1.0 INTRODUCTION Technological advances in both building design and the equipment used in modern slaughter and processing facilities has provided new opportunities for establishment operators to function at much higher production volumes than those plants constructed even a decade ago. Beef, poultry and swine have all seen significant advances in the facility operator’s ability to increase production volumes through the increased use of automation to perform many procedures that were formerly conducted through the use of traditional labour methods. Efficiency in plant monitoring methods have also changed dramatically through the application of science based quality assurance and food safety programs such as the Hazard Analysis Critical Control Point System (HACCP). These changes to plant operating methods also make it necessary to adjust and modernize the current method and approach to food inspection systems by CFIA in a modern slaughter facility in order that the Agency may continue to deliver reliable scientifically based methods of food safety inspection at these higher volumes. The High Line Speed Inspection System ( HLIS) is one such system that allows swine and beef slaughter facilities to operate at enhanced line speeds. This system can be implemented in federal establishments that slaughter market hogs as well as steers, heifers and mature cattle provided the facility operator agrees to certain facility and equipment modifications as well as specific process controls to ensure that the integrity of the product is maintained when it is produced under these high volume conditions. Before HLIS is adopted in any slaughter facility it is imperative that clear dialogue occurs between the CFIA and the facility operator regarding the resource impact of plant monitoring responsibilities, training needs, financial and human resource commitments. HLIS incorporates modifications to the traditional swine and beef postmortem inspection procedures and inspection station configurations by establishing presentation standards (PS) for the heads, viscera, and carcasses prior to inspection and finished product standards of performance (FPS) for carcasses. Additionally the establishment shall have a HACCP system in place that has been approved and recognized under CFIA’s FSEP program. HLIS provides an opportunity for the establishment to adjust to assuming a greater responsibility for managing the quality and safety of their product through an initial one time CFIA certified training program for their plant personnel. CFIA provides this initial training for any starting facility so an initial block of trained plant personnel may be established. Further training is then assumed by the establishment. This format provides a co-operative and shared "inspection" approach to the slaughter and carcass dressing procedures. Significant inspection station reductions are realized at higher line speeds due to efficiencies gained through minimized product handling and a shift toward greater responsibility on the part of the company to present and manage its own product. Under this program the establishment will be responsible for the identification and removal of defects that result during live handling, humane stunning, or dressing operations collectively referred to as "manufacturing defects". The operator will also assume responsibility for the removal of certain minor specified trimmable pathological conditions (TPC’s). Removal of these defects will be accomplished by plant personnel that have undergone a training and accreditation program to become designated "Accredited Trimmers, Presenters, Monitors, Detectors." The establishment employee training program is to be established in writing and approved by the Veterinarian in Charge (VIC)/Regional Veterinary Officer (RVO). 1.1 WRITTEN QUALITY ASSURANCE PROGRAM/(FSEP)HACCP SYSTEM: As mentioned earlier, before HLIS can be introduced into a registered facility the establishment shall be fully recognized under a CFIA’s FSEP/HACCP Program. The HACCP System should reflect distinct levels for managing and monitoring the HLIS program; normally Plant Production performs product control and monitoring (monitoring may be optional), Quality Control (QC) performs verification and CFIA functions in an oversight capacity to monitor and verify the overall testing activities of both groups. For the system to operate properly, each of these three levels of evaluation needs to function independently while remaining part of one system. In certain facility settings it may be more advantageous and effective to have only the Quality Control Department responsible for monitoring and verification procedures provided these activities are performed by different individuals. The entire slaughter process may be divided into operational zones for easier control and monitoring of the program if the company so chooses. Again, this should be reflected in the written program along with all monitoring/process control points, employee training and accreditation programs and submitted to the VIC for review and approval. 1.2 PRODUCT TESTING: Under traditional inspection, the Veterinarian-in-Charge has the authority to require line speed reductions or stoppages as well as other corrective actions when post-mortem inspection cannot be adequately performed at the current line speed because of preparation or presentation deficiencies or because of disease incidence etc. Under HLIS procedures the VIC or his/her designated Inspector still retains this final authority to stop the line or reduce its speed if it is evident that the plant’s efforts are failing to manage the problem. Due to the high volume and rapid line speeds that these plants operate at all alternative process actions to manage the problem should be thoroughly considered before the decision to stop or reduce line speed is taken. If it is apparent from performance data that an operator cannot consistently perform at an acceptable AQL for any of the process control steps in HLIS the line speed maximums shall be re-assessed by the VIC and the facility operator. See below also. Only designated trained industry personnel shall perform the tests described in the program. The test results are recorded in company logs/record sheets. It is normally the plant QC monitor's responsibility to review the entries made in the records for timeliness and accuracy and to assure that appropriate action is taken when the standards are not met. The QC monitor (or designated equivalent) will also conduct independent tests and compare the results of these with those of Production if applicable. In turn, CFIA personnel will periodically monitor the plant's quality control program by monitoring production activities, reviewing company records and by comparing and correlating the results of their own tests with those conducted by Production and/or plant Quality Control. Unless otherwise stated in this policy the CFIA will perform on a random basis a minimum of one correlation test during each half shift during the initial 60 operating days of the program in order to validate operator results for the following; Presentation, Shewhart control chart and carcass FPS testing. At the discretion of the Veterinarian in Charge or designate one or more additional correlation tests may be performed during a production shift if it is determined that product performance or test results are being affected or influenced by unusual or extraordinary circumstances or poor operator performance. The Veterinarian in Charge shall have discretion in initiating corrective action through consultation with the operator if it is determined that unsatisfactory or poor product/employee performance is occurring during non testing intervals or there is a general difficulty in achieving consistent satisfactory test score results. Repetitive occurrences shall be documented on the appropriate record and corrective action shall be undertaken by the operator or at the direction of the VIC/delegate. If it becomes apparent from historical performance data (5 consecutive shifts or more) that an operator cannot perform consistently* at an established AQL for any of the process control steps in the HLIS program and previous corrective action undertakings by the operator have not provided long term resolution to the problem, then the line speed maximums for the process step(s) involved shall be re-assessed by the VIC/RVO and the Operator and reset to a lower maximum level, using an initial increment reduction of 10%. If the initial line speed reduction does not provide satisfactory improvements within the first operating ½ shift a further reduction(s) shall be imposed until the accepted AQL for the affected process step(s) has been re-established. From the time a satisfactory line speed and associated AQL is established it shall remain in place for a minimum of 5 consecutive working shifts. If during this reduced line speed period the operator can clearly demonstrate that the initial cause of the original under performance was due to a discrete and specific operational issue that has subsequently been fully corrected the operator may then request that the VIC immediately commence to restore line speeds to their original values in the same increments that they were reduced. Once restored should the same or similar under performance issues again arise within a 5 consecutive shift period the line speed shall be immediately reduced to it’s former level and shall remain at this or a lesser line speed until 5 consecutive shifts have been completed at which time the Operator and the VIC/RVO shall consult and agree as to whether or not it is appropriate from records of performance for the past 5 shifts to restore line speeds to their original values. If CFIA’s correlation test result fails to correlate with that of the monitor an immediate retest shall be performed and QC will be notified. Two consecutive non matching correlation tests between the operator and CFIA will require that process action be initiated by the operator (if applicable) based on the results of the second CFIA test which shall be taken as the correct score. CFIA will monitor all Plant Production and QC corrective action activities to ensure program requirements are met. The discrepancy in scoring results shall be investigated and reconciled in consultation with the VIC after all required process actions have been implemented. *Note: For all AQL’s (or equivalent) assigned to a process control step in the HLIS program a participating operator shall be expected to achieve at least the 80th percentile of performance on average when results from CFIA and the Operator are jointly examined over a period of 5 consecutive working shifts or longer. 1.3 GENERAL RESPONSIBILITIES : Once a facility has had its application for HLIS inspection staff resources approved within the Region it will then be subject to a review process to confirm that it can provide adequate resources, materials and facilities to meet the requirements of the HLIS policy on an ongoing basis. In addition, those process steps that will be subject to a performance standard under the HLIS policy shall first have their existing performance level assessed. This shall be done by gathering sets of baseline data prior to implementing any process controls at these locations under the HLIS policy. Performance Standards: The HLIS policy introduces the application of process controls at certain critical locations along the processing line. In order to fairly assess these control points it is important to know what level the plant was performing at prior to entering the HLIS program and to also know at what level it is able to maintain itself. Therefore performance data based on a minimum of fifty sample sets taken at each designated process step gathered over a minimum of 10 working days are required before the facility may begin to apply the HLIS process controls at these locations. Facility and Resource Requirements: Under the HLIS Program Plant Management shall agree to provide an approved facility that meets CFIA HLIS and MOP construction standards. Before a facility can be approved for HLIS operations it shall undergo a facility review by the responsible Area Program and Regional Operational specialists along with the VIC to validate that all HLIS facility standards are in compliance with the policy requirements See Forms CFIA/ HLIS 006/007: Beef/Swine Program Facility Assessment. Once the facility review is satisfactorily completed a signed Letter of Commitment from a responsible company officer shall be forwarded to the Veterinarian in Charge addressing items a) through e) below. a) the operator agrees to maintain a facility that meets the criteria referenced in the HLIS policy and/or CFIA Manual of Procedures (MOP) once the HLIS program application is approved. b) the operator agrees to provide sufficient material(s), financial and human resources, to carry out the various functions and responsibilities designated to the establishment under the HLIS Program. c) the operator agrees to carry out all functions and responsibilities assigned to the establishment under the HLIS program and to take all necessary actions as indicated therein during the operation of the HLIS program. d) should the operator decide to withdraw from the HLIS program CFIA shall be provided with written notification of the operator’s decision10 working days prior to the final scheduled day of HLIS operations. After 6 months of continuous absence from the HLIS program the establishment shall lose its certification as an approved HLIS facility. e) while certified as an HLIS facility all slaughter operations shall be performed in accordance with the HLIS program. The letter of commitment shall be renewed at least annually or upon departure of the responsible signing official. Note: The application of this HLIS policy manual must at all times remain in conformity with the Meat Inspection Act, Meat Inspection Regulations, Manual of Procedures as well as the Food Safety Enhancement Program. Unresolved differences in the interpretation of the application of the HLIS policy between facility CFIA personnel and the operator may be referred to CFIA headquarters for written clarification. During this interim period the decision of the Veterinarian in Charge/Regional Veterinary Officer shall prevail. 2.0 INTRODUCTION: STATISTICAL PROCESS CONTROLS: All slaughtering plants are responsible for producing product that is consistently in compliance with minimum food safety standards as set out in the Meat Inspection Act and Regulations, Manual of Procedures and The Food Safety Enhancement Program (MIA, MIR, MOP and FSEP). In order to be able to evaluate as well as enhance an operator’s ability to comply to these standards the HLIS program incorporates the use of Statistical Process Controls (SPC). These are science based tools that help to improve and at the same time objectively measure the performance effectiveness of a manufacturing process. Under this system dressed carcasses and their relevant portions must meet several performance criteria during the dressing procedure. These performance criteria are applied in the form of Presentation Standards (PS), Finished Product Standards (FPS) and Control Chart performance standards. These tools provide the means for assessing the carcass and portions for food safety and wholesomeness while also determining if the slaughter process is in control. The PS, FPS and Control Chart tests are all tools that are applied at specified locations by randomly sampling and testing the carcass and/or its associated portions during the production shift for a pre-determined level of manufacturing performance. 2.1 INTRODUCTION TO CONTROL CHARTS: This section provides a brief introduction to the use of Control Charts. For detailed information on this as well as Presentation Standards and Finished Product Standards information. See Training Module A 45, Annex 1-5 and Sections 6 and 7 of this policy. Control charts are used in various manufacturing environments to provide a statistical indication of how effectively a certain manufacturing step(s) is performing under a prescribed set of Quality Assurance standards. Their importance rests in being statistically reliable in evaluating the manufacturing step they are assessing. For optimal benefit it is critical that this evaluation occurs at a location immediately downstream from the process step that is being evaluated in order to provide real time performance measurement and feed back to the operating step under evaluation. The Shewhart Control Chart operates on the principle of measuring a process step’s departure from mean or average performance through the use of units of standard deviation. This approach has been shown to be an objective statistically reliable means of determining when early process intervention is warranted. The application of the Shewhart Control Chart provides the additional benefit of allowing the use of ISO special sampling plans for evaluating final carcass performance rather than the conventional General Inspection Level II sampling plan which requires a larger carcass sample size. A trained and accredited plant employee shall conduct scheduled randomized hourly control chart tests on 10 consecutive carcasses immediately after the evisceration step and prior to any further alteration or trimming of the carcass (in the event a facility performs hide removal a similar station shall be located after the last de-hiding procedure and prior to any further processing step). The carcasses will only be scored as "positive" or "negative" for the presence of any distinguishable fecal or ingesta defect related to the evisceration step. Any carcass found to be attribute positive during the test shall be clearly "marked" for positive identification and correction along the processing line prior to final approval. All test results are to be recorded on Form CFIA/ HLIS 001S. CFIA will periodically monitor operator testing and recording activities during the production shift and will perform a minimum of one correlation test per half shift. See section 1.2. TABLE 2.1
2.2 CORRECTIVE ACTIONS FOR SHEWHART CONTROL CHART DEVIATIONS: As previously noted the Shewhart Control chart evaluates a process on the principle of units of standard deviation from the mean or average performance. One standard deviation (+/-) from average performance is considered to be acceptable or satisfactory performance. Two standard deviations is considered fair performance and three or four standard deviations are viewed as unsatisfactory performance. See Appendix A Shewhart Control Chart Decision Tree. Satisfactory Performance: Green Zone: No action required. Fair Performance: Yellow Zone: Random testing shall be immediately suspended and the operator shall initiate immediate corrective actions as detailed in the facility’s written program. All corrective action procedures shall have been previously approved by the VIC and RVO. Once corrective measures have been implemented the operator shall perform an immediate retest. Two consecutive satisfactory test scores taken at least 15 minutes apart shall be achieved before random testing is resumed. If the retest score remains in the fair performance zone after any two consecutive retests the floor supervisor and the VIC/delegate shall consult on the next course of action which shall include a line speed reduction. Unsatisfactory Performance: Red Zone: Upon scoring an unsatisfactory test result random testing shall be suspended and an immediate 10% line speed reduction shall be initiated by the operator along with the corrective measures as approved and detailed in the facility’s written program. These corrective measures shall have been previously approved by the VIC and Area Program Specialist/RVO. CFIA shall be notified immediately whenever an unsatisfactory score is recorded. Once corrective measures have been satisfactorily implemented a retest shall be performed by the operator no earlier than 15 minutes after the previously failed test. The operator shall first achieve a satisfactory score on the initial retest before line speed increases may commence. Upon completion of each consecutive satisfactory 15 minute retest thereafter the line speed may be increased by the same increment it was reduced until original line speed is re-established. When two consecutive satisfactory retest scores have been achieved and the line speed has returned to normal random testing frequencies shall be resumed. In the event of a second consecutive unsatisfactory retest score a further 10% line speed reduction shall occur with re-evaluation of the corrective measures and consultation between the VIC/delegate and floor supervisor. Also see Product Testing Section 1.2, Appendix A Decision Tree. Note: The corrective actions outlined in Appendix A are the minimum actions required at the entry level of the program. Based on individual plant performance the corrective actions decision tree may be modified to reflect an operator’s improved data performance profile wherein a line speed reduction would not occur until 2 consecutive red zone failures had occurred (or some similar modification). These changes shall be approved by the Area and National Program based on supporting establishment data. 3.0 PERSONNEL REQUIREMENTS 3.1 TRAINING: 3.1.1 Training Protocol for Accredited Plant Employees: An important part of the success of HLIS is the training and accreditation of key plant personnel. The positions for which accreditation is required are Presenters, Detectors, Trimmers, and Monitors. Training and accreditation for the initial group of plant employees will be done by CFIA certified staff using the CFIA National Training Program. Accreditation requires successful completion of both a theoretical classroom session as well as a practical evaluation. All subsequent training of new staff will be performed by accredited plant personnel through the establishment’s HLIS training program. Thereafter CFIA under the supervision of the VIC/delegate will only monitor the training of plant personnel as well as the plant’s written program to ensure sufficient training standards are being maintained. The VIC shall be responsible for approving the establishment’s HLIS training program and shall review the establishment’s HLIS employee training program at least annually to ensure that it is current and complete including records of all accredited employees. Should six or more consecutive calendar months lapse in which any accredited plant employee is not exposed to the application and/or practices of the HLIS program any such affected employee will be required to undergo a refresher training course and satisfactorily demonstrate their knowledge and application of the HLIS program before being re-accredited. The QA Department shall be responsible for monitoring and maintaining the accredited status of their employees. The VIC has the right to decertify any accredited plant employee by having their name removed from the company eligibility roster. There must be demonstrable factual information to show that the individual is not able to meet the required standards. A protocol describing the process of deaccreditation and retraining must be included in the establishment’s HLIS written program. 3.1.1 (1) Plant Employee Accreditation: a) CARCASS DEFECT TRIMMER: (see also 5.3.1) In order to accredit an employee as a "trimmer" the operator shall demonstrate that the following conditions are met: i) The accredited trimmers are establishment employees who are trained and accredited as proficient in the detection and sanitary removal of dressing nonconformances and Category I trimmable pathological conditions (TPC’s). ii) The operator takes full responsibility for the training/re-training of accredited trimmers as well as for testing for proficiency as per CFIA HLIS training program criteria. iii) A current written training program signed off by a responsible plant officer, which outlines the establishment's training and testing procedures is maintained on file and approved by the Veterinarian-in-Charge and shall be made available upon request. iv) Maintenance of a current roster of employees who have passed the plant accreditation process is maintained on file and a current copy of the roster shall submitted to the Veterinarian-in-Charge at least quarterly and be available on demand should the need to consult the roster arise during the intervening period. b) CARCASS DEFECT DETECTORS (see also 5.3.1) As for 3.1.1 a) c) PRESENTERS; Heads, Carcass, Viscera i) The accredited presenters are proficient in preparing/orienting the appropriate portions in a manner that conforms to minimum performance standards. Items II-IV under 3.1.1a) are applicable. d) PROCESS CONTROL MONITORS; Shewhart Control Chart, Presentation, FPS for FS and other carcass defects (includes Rework). i) The process control monitors shall be proficient in their knowledge, understanding and application of the respective detection, scoring, recording and process action activities associated with the described positions for which they assume responsibility. Items II-IV under 3.1.1a) are applicable. Note: When an accredited plant employee is required to perform more than one task, be it another accredited task or non accredited task relating to that person’s job, that employee shall not be distracted by additional responsibilities that would prevent him/her from otherwise satisfactorily performing the accredited functions of the position as if it were his/her sole responsibility. For example, the detector/trimmer function is often assigned as a joint responsibility. This may only occur if the above conditions can be met and there is an auditable means available for assessing detection and trimming performance. 3.1.1 (2) CFIA Employees: a) INDETERMINATE EMPLOYEES: CFIA Employees are initially trained and certified through the CFIA National Certification Program. Should a lapse of six consecutive calendar months or more occur where a certified CFIA inspector has not been exposed to the principles and applications of the HLIS program they shall be required to undergo a refresher training course in accordance with the National Training Program guidelines. Under the direction of the VIC or his/her Supervisory delegate the candidate shall satisfactorily demonstrate their knowledge and application of the program through a written and practical test process. b) SEASONAL/TEMPORARY EMPLOYEES: CFIA employees in this category will be trained for limited participation in the HLIS program. They shall be trained to understand and perform the necessary post mortem functions (see post mortem Modules 40 and 44) but shall not be responsible for floor monitoring activities. They shall be responsible for understanding and reporting on the activities of those plant employees who are improperly preparing carcasses and their portions for post mortem inspection. Any such employee who works in this capacity for greater than six continuous calendar months. (183 continuous calendar days) shall receive full HLIS certification training. 3.2 PLANT OPERATIONS: 3.2.1 Plant Production Plant Production designated staff shall assume the following responsibilities:
3.2.2 Plant Quality Assurance/Control Quality Assurance/Control designated staff shall assume the following responsibilities:
3.2.3 CFIA Inspection Staff CFIA shall assume the following responsibilities:
4.0 FACILITY REQUIREMENTS In addition to inspection facilities required under the Meat Inspection Act and Regulations and Manual of Procedures the following additional facilities/equipment are required for the implementation of the HLIS program. (1) Mirrors: Each carcass inspection station shall be equipped with a distortion free mirror(s) of sufficient size to provide a clear unobstructed view of the entire dorsal surfaces of the largest carcasses processed and provide a horizontal width at least equivalent to that of the CFIA inspection station(s). 2 metres x 2 metres is a recommended size/station. The mirror system can be a one piece tiltable mirror or a 2 piece vertical (to view the dorsal surface) canted (to view the posterior surface) system. In either case the mirror system shall be placed far enough from the vertical plane of the carcass to allow the carcass to be turned without contacting the mirror but close enough to provide the required view of the carcass. Swine Only:{ The installation of a distortion free mirror at the viscera inspection station area is left to the discretion of the VIC. Based upon the method of viscera presentation (e.g. hook and pan arrangement) and disposal this may or may not be of benefit. The mirror does provide a benefit in certain hook and pan configurations.} The decision to install a distortion free mirror at the Shewhart control chart station to detect fecal spillage as a result of the bunging operation shall be made by the VIC of each HLIS facility. This decision shall be based on the nature of the equipment and the specific procedure being applied at the bunging station. (2) Lighting: A minimum of 1000 lux of shadow-free lighting with a minimum Colour Rendering Index ( CRI) of 85 is required at each postmortem inspection station and associated company detection station, Shewhart carcass inspection station and each product reinspection station. In addition, a diffuse light source (such as a double tube fluorescent light fixture) shall be mounted at the top of the carcass mirror to provide a minimum of 1000 lux of lighting at the carcass shoulder level. Directional lighting may also be required at the carcass inspection station to ensure that sufficient lighting is provided inside the thoracic cavity of the carcass as it passes through the inspection zone. (3) Carcass centre spacing: The minimum distance between swine carcass centres shall be 61.0 cm (24 inches) and 1.83 metres (6.0 ft.) for beef. (4) Table Width: The minimum moving table width shall be 1.52 meters (5 ft). However the table shall be sufficiently wide enough and sufficiently long enough to provide a drag space to allow for the proper inspection of viscera and prevent any interference and/or common contact from other portions of the same carcass or from other carcasses. (5) CFIA Inspection/Plant employee Space Requirements: Adequate unencroached space shall be available for those plant employees who are responsible for proper presentation of heads and viscera for inspection as well as for the performance of presentation testing. Presentation testing requires a minimum of 92 cm. (3 feet). This space should be located next to and upstream from the various inspection stations. Each head, viscera and carcass CFIA inspection station requires 185 cm (6 feet) of adjustable platform work space without encroachments. (6) Sanitizers: Must be of sufficient size and readily accessible to an inspector’s working position. (7) Shewhart Test Stations: The Shewhart inspection stand or allocated space shall be in conformance with the space requirements of the presentation station and shall have lighting standards as for final carcass inspection. It shall be positioned close enough to the carcass line (comfortable arm’s length) to satisfy OSH requirements and so the evaluator may manipulate the carcass if necessary. It shall be located directly after the process step(s) it evaluates and prior to any further alteration to the product. This provides for effective evaluation of the process step and a timely response interval when process action is required. A sanitizer is not required if trimming is not performed. Beef operators shall provide three Shewhart test stations. Two stations shall evaluate hide removal. These shall be located so they can evaluate the rump/bung area and the shank/brisket area immediately after hide removal. The third station shall evaluate the evisceration procedure. In swine only the latter station is required unless hides are being removed. (8) Head Station (Cervical): BEEF ONLY: The space required to perform head (cervical) inspection is based on minimum unobstructed work space for head inspectors when heads are presented on 1.22 meters (4 ft.) centers. If spacing is greater than 1.22 meters (4 ft.), extra work space may be required. See Table 4.1
(9) Viscera Beef Only The requirement for the beef viscera inspection station is 2.44 meters (8 ft) per inspector. (10) Carcass Finished Product Standards Test Stations: The evisceration floor carcass FPS test station shall be located off the main chain and be adequate in length to collect, inspect and hold the required number of carcasses for a sample set based on ISO sampling plan 2859-1. On line inspection may be performed in a registered facility but only after an acceptable study has been performed and approved by National Headquarters to demonstrate its equivalency to off-line inspection. It is necessary that it be located downstream from all company trimming procedures and shall be placed, in the case of swine, before the final carcass wash cabinet. This station must also be equipped with a permanent platform preferably adjustable with enough room to allow two people access to all levels of the carcass. It shall be equipped with a sanitizer, soap and towels and safety rails, have a minimum 1000 lux of shadow-free lighting with a minimum CRI of 85 and have a clipboard holder for holding recording sheets. {Beef Only}{The inside/outside carcass inspection platform shall be large enough to accommodate two persons, may be adjustable, shall be equipped with safety devices to prevent anyone from falling off the platform, and shall be designed to allow for quick exit. The platform shall be located opposite the mirror prior to the splitting saw and in a position such that the carcass inspector can easily view the viscera table and communicate with the viscera inspector. Each platform is to be equipped with a sanitizer, sink, soap, and towels. The sink shall be installed on the outside of the platform, not inside. The platform shall be a minimum of 0.75 metres (2.5 ft) wide and 1.83 metres (6 ft) long with the lengthwise dimension running parallel to the moving chain. Unhampered access to and from the platform shall be provided. The platform shall be designed with a 1.05 metre (42") high back rail and 1.27 cm (l/2") foot bumpers on all sides, excluding access and exit points.} {Beef Only} { If adjustable, as measured from the rail, the upper platform height can be less than or equal to 2.54 metres (l00 inches). The lower platform can be greater than or equal to 2.85 metres (ll2 inches). If adjustable, as measured from the floor, the upper platform can be greater than or equal to 1.17 metres (46 inches). The lower platform height can be less than or equal to 83.82 cm (33 inches).} (11) Carcass Cooler Rework/Trim Station: The carcass cooler reinspection station may be a permanent trim station or mobile station. The location of the stand shall be in an open area, avoid common contact and shall receive the final approval of the Veterinarian in Charge/Area Program Specialist. Each stand must adhere to OSH safety guidelines and be fully equipped with a sanitizer, record/clipboard holder and sufficient lighting (1000 lux) shall be provided with convenient access to handwash facilities. (12) Carcass Rework Holding Capacity: Sufficient cooler space/rails shall be provided to separate detained lots of carcasses that have been identified for rework or reconditioning procedures by CFIA or the operator from those carcass lots that have been approved. An acceptable area that will allow effective rework of the detained lot shall be provided. (13) Display metre: An accurate digital line speed indicator (chain speed) for the carcass evisceration chain must be provided on the slaughter floor so that it be easily read by the inspectors performing presentation testing. 5.0 GENERAL INSPECTION PROCEDURES 5.1 CFIA Post-Mortem Inspection Procedures Under HLIS there are a number of changes that affect postmortem carcass and portion presentation methods when compared to those procedures that occur in plants under traditional inspection. With respect to specific CFIA post mortem inspection tasks in a HLIS facility all procedures remain essentially the same as in traditional inspection but with a notable reduction in manipulation of portions and carcasses resulting in a reduction of the number of required inspection stations at higher line speeds. CFIA Inspectors working on line shall only be responsible for identifying Category II Trimmable Pathological Conditions (TPC’s) and not for conditions that are classified as dressing defects or Category I TPC’s (see table 7.1). Conditions such as toenails, eyelids, hair etc. are the responsibility of operator. It is the responsibility of the plant Detector to identify defective conditions and decide if the carcass is to be railed out for trimming or left on line. It may not be possible at higher speeds for one person to identify, mark and trim carcasses. Therefore once determined by the VIC and or RVO that an individual cannot perform multiple tasks effectively the Detector(s) shall only identify and mark dressing defects and Category I TPC’s and one or more accredited Trimmers shall be in place to effectively perform the sanitary removal of the identified defects (or some acceptable alternative). CFIA INSPECTION STATION REQUIREMENTS - SWINE AND BEEF
Note: In plants where the viscera inspectors are unable to adequately visualize the carcass, the number of viscera inspection positions are reduced by one and one carcass inspection position is added on the main carcass line; this inspector shall be assisted by an accredited plant Detector. At the discretion of the VIC the ratio or distribution of carcass/viscera inspectors may be reconfigured (total # remains the same) as operational requirements may dictate and provided inspectional control is maintained.
* Where a facility uses a mechanically driven chain for the continuous movement of carcasses along the evisceration line the chain speed shall be assessed as the gross uninterrupted speed calculated over a 60 second cycle past a fixed point and shall not be calculated on the net number of carcasses dressed per hour. The HLIS monitor position shall be managed through the use of inspection station rotation. CFIA inspection personnel shall perform general daily record monitoring, perform correlation tests for presentation standards, finished carcass product standards and Shewhart control chart performance as per specified frequencies and generally oversee the activities of the Production and QC departments. It is recommended that the same individual be assigned to the floor monitoring position for at least the full shift and work in conjunction with and under the supervision of the slaughter floor veterinarian. The figures that are indicated for the various inspection stations may be impacted by various facility configurations with respect to carcass presentation. The VIC may re-distribute the recommended staffing numbers as s/he may so determine in conjunction with the Area Program Specialist/Regional Veterinary Officer provided the total numbers are not altered. 5.2 RANDOM TESTING GUIDELINE One of the major principles in any statistical testing program involving the selection of samples is that each unit in the population should have an equal chance of being selected as a sample. This is not completely possible under HLIS slaughtering conditions. These guidelines are intended to support that principle within the practical restraints of this inspection system. Plant Personnel As a general observation production employees should be exempted from the testing procedure if they may be in a compromised circumstance with respect to objectivity when conducting these tests. If a production employee is used in performing any test special efforts should be in place to ensure s/he is not influenced by the presence of the Production Supervisor. It is recommended that the QC Department be in charge of all testing requirements when this situation is encountered. The VIC shall review this situation in their respective facilities and determine what arrangement is most effective in providing the most reliable product evaluation procedure. Finished Product Standard (FPS) Checks A designated plant person(s) shall select random times according to the plant’s written program for conducting the carcass tests for food safety and non food safety defects. The selected times shall be submitted to the Veterinarian-in-Charge or his/her designate by the operator before the beginning of each shift. Presentation Checks: The operator need only perform the required checks within the thirty minute or one hour period required by the program, additional randomness is not required. These test times shall also be submitted to the Veterinarian-in-Charge or his/her designate by the operator before the start of each shift. Shewhart Control Chart Checks: These shall be performed by the operator on a random basis ensuring that each hour of the production shift is tested. The schedule of times shall be submitted to the Veterinarian in Charge or his/her designate by the operator prior to the start of each shift. Rework Checks: These shall be performed by the operator after all rework tasks have been performed on the detained lot. The entire population of the lot shall have an equal opportunity of being selected for the carcass subgroup test. The CFIA shall be notified when a rework is being performed on a detained lot and records of performance shall be maintained by the operator. Rework testing frequency by CFIA shall be discretionary. Carcass Testing: When the various carcass monitoring tests and evaluations are being performed either by the operator or by CFIA the general rule of observation is that the proximity of the carcass surface shall beat arm’s length and conducted from an acceptable inspection platform as referenced under sec 4.0 Facility Standards. CFIA Oversight and Verification Activities: CFIA shall perform daily periodic oversight monitoring and verification functions with respect to the operator’s testing, recording activities as well as employee performance to ensure the satisfactory application of the HLIS program. These activities shall also include randomly scheduled daily correlation tests but may also include unscheduled or spontaneous correlation tests if deemed necessary by the Veterinarian in Charge or the delegated EG 04 (equivalent) supervisor. Independent verification tests of a particular process control step are not routinely performed by CFIA but at the discretion of the VIC such test(s) may be authorized where it is determined that such a test is warranted. 5.3 CFIA/Accredited Employee Carcass Identification and Trimming Procedures: CFIA HELD tags are to be used for conditions requiring veterinary disposition (category II TPC) or in special circumstances as deemed necessary by CFIA personnel. In addition, an in-plant identification tag or ink marking system will be used by plant employees to identify dressing defects and Category I TPC’s. In-plant identification tags or ink marks must be removed once the defect is corrected. Defects so identified may be trimmed at any working position down the line or off line at the plant's discretion as long as the defect is removed sanitarily before leaving the final carcass approval area. CFIA HELD tags may only be removed (not repositioned) by a CFIA inspector or by an accredited plant employee under the direct and immediate supervision of a CFIA inspector. 5.3.1a Duties of Trained/Accredited Plant Personnel - Sec 5.3.1a SWINE ONLY (1) Head/Mandibular Lymph Node Presenter: a) Dorsal Presentation: carcass is approached from the dorsal side and the head is disarticulated at the atlanto-occipital joint and dropped but shall remain attached to carcass by the jowl skin. The mandibular lymph nodes shall be presented at the angle of the mandible (see diagram). The tongue shall remain in the buccal cavity until after final carcass inspection. b) Ventral Presentation: head is not disarticulated and access to lymph nodes is prepared in traditional manner via a ventral pharyngeal opening with mandibular lymph nodes exposed in the area of the mandibular angle. The tongue shall remain in the buccal cavity until after final carcass inspection. c) Attached to Tongue: Both mandibular lymph nodes are attached to laryngeal/lingual area. (2) Viscera Presenter: The viscera shall be presented in a consistent orientation that normally provides a hands free environment for the CFIA inspector. Under normal operating conditions the plant will provide one or more "presenters" upstream from the CFIA inspection station to ensure the all viscera are properly oriented to meet the presentation scoring standard. (3) Kidney/Carcass Presenter: The kidney presenter must expose the kidneys in the carcass for visual inspection before the carcass is in front of the viscera/carcass inspector. This employee will either; a) Remove and place in viscera pan all abnormal kidneys and be instructed by inspection staff on a protocol for handling hydronephrosis kidneys. OR b) Leave all kidneys in the carcass (IF PANS ARE TOO FAR FROM CARCASSES) and be instructed by CFIA staff on a protocol for handling hydronephrosis kidneys. (4) Carcass Detector: The carcass detector will use an approved in plant marking system to identify all dressing defects and Category I TPC’s and also place CFIA HELD tags on certain carcasses at the direction of CFIA Inspection staff. (5) Carcass Trimmers: The carcass trimmer will trim all identified defects on line or off line but NO trimming shall be performed on CFIA HELD carcasses until after veterinary disposition. CFIA Held tags are only removed after trimming and at the direction of a CFIA Inspector. The carcass trimmers shall remove all other identification marks after trimming and no carcass shall leave the final carcass approval area until these procedures are completed. (6) Process Control Step Monitors: This includes those accredited employees who monitor all presenter activities, perform FPS (FS and OCD rework) carcass monitoring and Shewhart Control Chart monitoring. The monitors shall score, record and initiate process action as required in each of their respective monitoring functions. Note: When an accredited plant employee is required to perform more than one task, whether an accredited task or non accredited task relating to that person’s job, that employee shall not be distracted by additional responsibilities that would prevent him/her from otherwise satisfactorily performing the accredited functions of the position as if it were his/her sole responsibility. 5.3.1b Duties of Trained/Accredited Plant Personnel - Sec 5.3.1b BEEF ONLY (1) Head and Tongue Preparation and Presentation: Head and tongue preparation may vary between establishments such as tongue attached to the head or detached, head oriented up or head oriented down, but once decided must remain consistent within the establishment. The employee shall thoroughly palpate the tongue and mark or signal the CFIA inspector of any abnormalities. The employee shall also incise the lateral and medial muscles of mastication exposing predominantly muscle tissue (at least 75%) and minimum connective tissue (no more than 25%). The medial retro pharyngeal and mandibular lymph nodes shall be prepared and presented intact and in a consistent location. (2) Viscera Preparation and Presentation The viscera shall be presented in a consistent orientation that normally provides for minimum manipulation by the CFIA inspector. Under normal operating conditions the plant will provide one or more "presenters" upstream from the CFIA inspection station to ensure the all viscera are properly prepared and oriented. (a) Heart:- a trained plant employee shall open the heart such that all chambers are exposed and also incise the interventricular septum (b) Kidneys:- a trained employee shall open the kidney capsule (minimum 75%), remove them from the carcass and present them on the table in a consistent location for CFIA inspection. (c) Stomach/intestines:- a trained plant employee shall orient the rumen and its attached components in a consistent orientation as determined by the Veterinarian in Charge and the Area Program specialist. A diagram depicting the orientation of all viscera components shall be posted in the employee training area and in the CFIA inspection office. (3) Carcass Detectors: The carcass detector will use an approved in plant marking system to identify all dressing defects and Category I TPC’s and may also place CFIA HELD tags on certain carcasses at the direction of CFIA Inspection staff. (4) Carcass Trimmers: The carcass trimmer will trim all identified defects on line or off line but NO trimming shall be performed on CFIA HELD carcasses until after veterinary disposition. CFIA Held tags are only removed after trimming and at the direction of a CFIA Inspector. The carcass trimmers shall remove all other identification marks after trimming and no carcass shall leave the final carcass approval area until these procedures are completed. (5) Process Control Step Monitors: This includes those accredited employees who monitor all presenter activities, perform FPS (FS and OCD rework) carcass monitoring and Shewhart Control Chart monitoring. The monitors shall score, record and initiate process action as required in each of their respective monitoring functions. Note: When an accredited plant employee is required to perform more than one task, whether an accredited task or non accredited task relating to that person’s job, that employee shall not be distracted by additional responsibilities that would prevent him/her from otherwise satisfactorily performing the accredited functions of the position as if it were his/her sole responsibility. 6.0 PRESENTATION STANDARDS The provision for uniform presentation standards is a key element in the implementation of HLIS. It provides not only consistency in presentation of the carcass and its portions but also reduces potential food safety concerns and offers early indication as to whether certain carcass dressing procedures are in control. Uniform presentation is essential in maintaining inspection efficiency and is critical at the higher rates of slaughter. When the carcass or its parts are not uniformly presented in a predetermined manner, time allotted for inspection must be used to correct or compensate for presentation errors. Therefore, the presentation standards must be met to ensure the effectiveness and efficiency of inspection when the HLIS standards are used. The adequacy of presentation is affected by several factors such as disease conditions, carcass uniformity, evisceration line configuration, sequence of evisceration procedures, adequate equipment, lighting, but most notably well trained and efficient production employees. 6.1 General Responsibilities: 6.1.1 Plant Responsibility: Plant management is responsible for implementing the prescribed presentation standards as well as initiating all corrective actions. The operator shall ensure the proper presentation of heads, carcasses and viscera using trained accredited personnel. The operator shall also designate responsible persons to schedule and conduct monitoring tests and take corrective action whenever the required standards are not met. This function is normally shared between Production and QC but may be performed by the QC Department alone if the operator so chooses. The VIC/delegate shall be informed whenever process action is initiated. See Table 6.1 6.1.2 CFIA Inspection Responsibility: Inspection personnel will monitor the activities of plant employees assigned to perform presentation monitoring checks. This will include evaluations of records, observation of employee performance and correlation tests for comparison with plant results. 6.2a PRESENTATION STANDARDS:- Sec 6.2a SWINE ONLY Note: Orientation for proper presentation is from the inspector's viewpoint facing perpendicular to the moving chain. 6.2a.1 HEAD-Dorsal Presentation(See figure 1) The head shall be presented in the dropped position attached to the carcass by the skin/soft tissue of the chin area, the atlanto-occipital joint severed or disarticulated with the mandibular region facing the Inspector. The mandibular lymph nodes must be readily accessible and attached to the mandible. The head shall normally be presented with essentially no movement that would be considered to interfere with the inspection procedure. The midline of the dorsal surface of the carcass with the dropped head attached shall face the Inspector. 6.2a.2 HEAD-Ventral Presentation The head shall be presented attached to the carcass with the ventral surface of the carcass/jowl area facing the Inspector. The mandibular lymph nodes must be readily accessible and consistently located in the same anatomical area as determined by the operator’s standards of carcass preparation. Head/carcass shall be presented with essentially no movement that would be considered to interfere with the inspection procedure. 6.2a.3 VISCERA Presentation (See figure 2& 3) (1) Red Offal Presentation (Hook): Red offal includes the larynx, trachea, esophagus, lungs, heart and liver and must be suspended from the hook by the larynx which is placed immediately adjacent to the hook cradle. Placement of the larynx in the cradle is critical to presenting the correct surface of the red offal for inspection (the tongue shall remain in the buccal cavity until after final carcass inspection).
(2) Gray Offal Presentation (Pan): Gray offal normally includes the gastrointestinal tract, spleen, uterus and bladder.
6.2a.4 CARCASS Presentation The carcass shall be presented split and hanging vertically in the open position so that the pleural and peritoneal cavity surfaces and kidneys are facing the inspector and are easily visualized with minimal or no carcass manipulation. In addition the entire dorsal surface of the carcass must be visible to the inspector by means of a mirror as s/he stands in front of the passing carcass. See section 4.1(1). 6.2b PRESENTATION STANDARDS:- Sec 6.2b BEEF ONLY 6.2b.1 Head Presentation: TONGUE: Tongue presentation may vary between establishments e.g. tongue in, tongue out, but must be consistent within an individual establishment. Prior to the inspector's examination of the tongue, an establishment employee is required to thoroughly palpate each tongue and notify the inspector if abnormalities were found. Notification to the inspector may be accomplished by directly signaling or by means of a marking system developed by the establishment and acceptable to the Veterinarian-in-Charge, such as ink, tags, cuts or other markings. There shall be no visible contamination from ingesta and there shall be no movement or sway of the tongue that would interfere/impede inspection activities. The inspector shall visually inspect each tongue and palpate any tongue identified as abnormal by the establishment employee or appearing abnormal to the inspector. LYMPH NODES: The parotid lymph nodes may be presented in their natural location or cut free along with their accompanying parotid salivary gland during the process of incising the masseter muscles and be presented attached to the lowest portion of the incised masseter muscle. The presentation must be consistent at one location or the other. The medial and lateral retro pharyngeal and mandibular lymph nodes must be presented intact and in a consistent location. No more than 50% of any lymph node shall be missing. HEAD: The head may be presented nostrils facing upwards or downwards but must be consistent. Prior to the inspector's examination of the head, an establishment employee is required correctly trim and dress the head, incise both lateral and medial muscles of mastication (cheeks) to expose the muscles for inspection. These incisions are to be made between the muscle planes so that 75% or more of the muscle is exposed, with no more than 25% of the exposed tissue consisting of white connective tissue, and with no more than l0% of the muscle surface obscured by blood. The head shall not be approved if it bears visible contamination from ingesta. It shall be the operator’s responsibility to ensure all heads are properly for CFIA inspection. Heads which are improperly prepared or display food safety dressing defects shall be so identified and controlled as inedible material by the operator. NOTE: The seepage of blood onto the exposed muscle surfaces may be reduced by cutting the blood vessels (common carotid artery and the external maxillary vein) at the angle of the mandible. Cutting these vessels before the head enters the final head wash cabinet reduces the amount of blood found on the cheeks at inspection. 6.2b.2 Viscera Presentation: (see figure 1) No red offal portion (heart, lungs, liver, kidney) shall be approved for edible use if visible food safety defects are present. The operator shall ensure that such portions are identified and appropriately controlled when they are the result of a dressing procedure. HEART/LUNGS: An establishment employee shall open all chambers of the heart and incise the interventricular septum to fully expose the interior of the heart for examination for CFIA inspection. KIDNEYS: An establishment employee shall open the kidney capsule, separate the kidneys from the carcass and present the kidneys for inspection with the viscera at the viscera station. STOMACH/INTESTINE: Small and large intestines shall be presented in a consistent orientation with the mesenteric chain fully exposed. NOTE: Spleens must be presented in full view to the viscera/carcass inspector in those establishments that do not separate spleen from the viscera. ORIENTATION: In each establishment the exact required placement of the various organs on the table is to be determined by the VIC in consultation with the Regional Program Specialist and establishment management. Schematic drawings of the approved viscera placement will be posted in the inspection office and in the establishment, where they can be readily viewed by inspection and production personnel. COMMON CONTACT: There shall be no co-mingling or common contact of viscera units belonging to different carcasses. Overlapping or obscuring of viscera portions from the same carcass due to improper placement and orientation shall also be prevented. DRAGGING/OVERHANG/PINCHING: No portion shall be pinched, overhang the table edges or be dragged along 6.2b.3 Carcass Presentation: The establishment shall present the dressed carcass for inspection in a manner that will ensure good visualization of the external surfaces, thoracic and abdominal cavities, and cut surfaces of the carcass with the hocks spread apart on 6 foot minimum centers. There shall be no movement of the carcass. No remnant portions shall be left in the carcass. Those carcasses that cannot be properly eviscerated as the result of pathological (physiological or disease origin) complications shall not be scored. 6.3 TESTING AND SCORING PRESENTATION STANDARDS 6.3.1 Test Procedures for Presentation Standards: The presentation tests will be made at the following frequencies. Also refer to section 6.1.1
CFIA will perform correlation tests in accordance with Table 6.1. CFIA will also perform periodic record monitoring activities to evaluate the entries made on presentation forms by establishment personnel. The frequency for such evaluations will be established by the Veterinarian-in-Charge. The inspector shall enter the date, time, and his/her initials at the bottom of each form evaluated, and if errors are found on the forms or they are not complete or timely, the inspector should describe the findings and actions taken on the bottom or back of the form. CFIA correlation test may also be recorded on the company form and will use a different colour of ink to distinguish CFIA information. Records of presentation tests shall be maintained for a period of one year. Line Speed Checks An accurate digital line speed indicator for both the head chain and the carcass chain is required at a location readily accessible to the person performing presentation tests. A 1% margin of error shall be allowed for inherent variations in the system. 6.3.2a Scoring Presentation Errors Section 6.3.2a SWINE ONLY Scoring of presentation errors is based on the ISO attribute system using Sampling Plan 2859-1. In each of the three presentation categories; heads, carcass and viscera a list of defects or attributes has been established to ensure that a minimum standard of presentation is maintained in each. ISO switching rules for Reduced, Normal and Tightened modes apply to this standard. Any attribute (condition/defect) described under Heads, Carcass or Viscera shall be scored as a defect. The AQL’s for each presentation category may vary depending on the complexity and number of attributes assigned to that procedure. Once determined these will be recorded in the company’s written program and on the records document. All results are to be recorded on Form CFIA/ HLIS 004A/B or C. Note: The presentation of any carcass or its parts which is adversely affected by the presence of a pathological/abnormal condition will not be scored for presentation. The next immediate trailing unit will be substituted in lieu and scored as part of the sample set. Presentation Error Categories: (1) HEAD (a) Lymph Nodes Mandibular lymph nodes must be presented intact (at least 50 per cent of each node) and consistently exposed in the area of the mandibular angle (ventral or dorsal approach). It must not be necessary to make an extra cut to expose the mandibular lymph node. Any procedure which leaves more than 1/2 of the lymph node in the neck area when using the dorsal presentation is considered to be a defect. >½ of one or both lymph nodes in the wrong location (neck) = 1 defect/attribute. >½ of one or both lymph nodes obscured from view = 1 defect/attribute (b) Detached Head Head (dorsal or ventral presentation) not attached or is only partially attached to carcass by normal skin attachment (regardless of whether reattached by other means). Head rotated >45 degrees = 1 defect. (c) Excessive Movement (dorsal or ventral presentation) Excessive head movement would be considered as any swinging or spinning motion that would interfere with or delay the inspector’s hook placement prior to incising the mandibular lymph nodes. This needs to be judged before the centre line of the first inspection station. (2) VISCERA - Hook and Pan Presentation (a) Red Offal (modified pluck includes larynx, trachea, esophagus, heart, liver and lungs) i) rotated > 90 degrees - 1 defect ii) pluck not suspended at the base of the larynx (exception trachea damaged) - 1 defect. iii) part of red offal not attached on hook but present in pan -1 defect. iv) entire organ(s) missing -1 defect. (b) Gray Offal i) rotated >45o left or right of standard position 1 defect. ii) grey offal (including spleen) is partially (greater than 50 per cent) or entirely missing 1 defect. iii) viscera/portions hanging outside pan/tray 1 defect. iv) not able to visualize at least 50 per cent of principle organs; spleen, hepatic lymph node, cecum, stomach, small intestine, rectum and mesenteric chain due to such things as improper presentation, dressing preparation, major contamination etc. resulting in manipulation of organs. 1 defect. (c) Generalized Contamination Whenever the red or grey offals are so contaminated that visualization is obscured and manual inspection through manipulation is required this shall be scored as 1 defect. (3) CARCASS (a) Unsplit/sides not attached/rotated Carcass not spread or presented to the inspector unsplit because of pathology do not count, the monitor skips this hog and continues selecting carcasses. Sides not attached in the pelvic and/or shoulder region (based on company’s carcass preparation standard), or the carcass is coming towards the inspector more than 45 degrees from the perpendicular, shall be scored as 1 defect. (b) Kidneys - not exposed/missing i) all kidneys shall be exposed. Each unexposed (i.e. the kidney is covered by more that 50% of the capsule/membrane) kidney shall be scored as 1 defect. This does not include kidneys with hydronephrosis. ii) at least one complete intact kidney and one half of the remaining kidney shall be present. Each absent kidney or missing portion exceeding one half is scored as 1 defect. 6.3.2b Scoring Presentation Errors: Section 6.3.2b BEEF ONLY Presentation Error Categories: (1) HEAD (a) Tongue (if presented separately may be hung by the tip or root but is scored as part of head presentation) i) visible GIT contamination present ii) improper orientation, turned > 45 degrees from center position (hung backwards, sideways) iii) no palpable/visual masses present iv) loss of identification v) portion missing (b) Head (may be suspended with head pointing up or down, tongue in or out) i) visible GIT contamination present ii) improper dressing (hide, eyelids, horns, lips, loose hairs) iii) improper preparation of head (<75% cheek muscles exposed/not incised, >25% blood obscuring surface, muscles not incised, tongue not palpated/lesion undetected) iv) loss of identification v) portion missing (>50% of any lymph node, tongue, medial/lateral masticatory muscle) (c) Kidneys i) visible GIT contamination present ii) improper position/orientation; incorrect schematic position, turned more than 45 degrees from normal center position. iii) improper preparation; > 25% covered by capsule iv) loss if identification, co-mingling, common contact with other carcass portions. v) portion missing; > 50% of organ missing (2) VISCERA (all viscera portions are scored collectively under this heading) (a) Heart i) visible GIT contamination present ii) improper position/orientation; incorrect schematic position, turned more than 45 degrees from normal center position. iii) improper preparation; heart not adequately opened, >25% surface obscured iv) loss of identification, co-mingling common contact with other carcass portions. v) portion missing; > 50% of organ missing (b) Liver i) visible GIT contamination present ii) improper position/orientation; incorrect schematic position, turned more than 45 degrees from normal center position, upside down etc. iii) loss if identification, co-mingling, common contact with other carcass portions. iv) portion missing; > 50% of organ missing, gall bladder, lymph node (c) GIT (gastro-intestinal tract) i) GIT internal spillage impeding inspection activities (inspector becomes contaminated, wash up, requires longer to perform duties etc.) ii) improper position/orientation; incorrect schematic position, turned more than 45 degrees from normal center position. iii) loss if identification, co-mingling common contact with other carcass portions. iv) portion missing; > 50% of organ missing, gall bladder, lymph node v) table overhang, dragging, pinching (d) Kidneys i) visible GIT contamination present ii) improper position/orientation; incorrect schematic position, turned more than 45 degrees from normal center position. iii) improper preparation; > 25% covered by capsule iv) loss if identification, co-mingling, common contact with other carcass portions. v) portion missing; > 50% of organ missing (3) CARCASS: i) generalized GIT contamination preventing inspection of carcass ii) improper orientation/position; hind legs not spread to specified distance for correct carcass exposure iii) improper dressing of carcass, remnant, unremoved organs/parts preventing final inspection 6.4 CORRECTIVE ACTIONS FOR FAILED PRESENTATION TESTS: Presentation checks shall be performed using ISO 2859-1 sample plan and the ISO switching rules between Reduced mode, Normal mode and Tightened mode shall apply. Sample size is based on the operator’s production volume. All new facilities shall commence testing in Normal mode. The results and follow up actions of all presentation tests are recorded on Form CFIA/ HLIS 004A/B or C for head, viscera or carcass presentation tests. All actions generated by presentation checks will be the establishment’s responsibility and may be initiated by either Plant Production or Quality Control. Under normal circumstances Plant Production and QC shall manage their respective process action issues separately unless otherwise defined in the company’s written program. If CFIA’s presentation correlation test result fails to correlate with that of the Presentation Monitor an immediate retest shall be performed and QC will be notified. Two consecutive non matching correlation tests between the operator and CFIA will require that process action be initiated by the operator (if applicable) based on the results of the second CFIA test which shall be taken as the correct score. CFIA will monitor all Plant Production and QC corrective action activities to ensure program requirements are met. The discrepancy in scoring results shall be investigated and reconciled in consultation with the VIC after all required process actions have been implemented. Also see Product Testing Section 1.2 Normal Mode The operator must continue to successfully pass four out of five consecutive random tests to maintain Normal mode status. Should the operator fail two presentation tests within any window of five consecutive tests the testing mode shall be switched to Tightened, no other corrective action shall be initiated. Tightened Mode Upon entering Tightened mode random testing shall be suspended and a presentation retest shall be conducted every 15 minutes until Normal mode is restored. Once returned to Normal mode random testing shall be resumed. After any two consecutive failures in Tightened mode the VIC or designate shall be notified and consultation between the operator and CFIA shall take place to determine the cause of the presentation under performance. At the discretion of the VIC a 10% line speed reduction may be exercised if immediate improvement cannot be achieved in the subsequent retest score. Reduced Mode Ten consecutive successful test scores in Normal mode shall be achieved before switching may occur to Reduced Mode. Any single failure of a test score in Reduced mode will move the operator back to Normal mode. No other corrective actions shall be initiated. Excessive Line Speed If on any test the line speed is found to exceed the currently allowed rate as per table 5.1A, B or C an immediate line speed reduction to the allowed rate is required. After any line speed reduction the line speed shall be rechecked after 15 minutes. If the line speed is above the currently allowed rate after the retest the VIC/delegate must be notified and a 10% reduction from the current maximum allowed line speed will apply. 7.0 FINISHED PRODUCT STANDARDS FOR CARCASSES: It is critical in slaughter production environments to be able to perform periodic product evaluations on the finished product in order to validate effective hygienic manufacturing performance. Finished product standards are one of several tools designed to ensure that the procedures used in preparing and approving a dressed food animal carcass are in control and are producing a product that is in conformance with CFIA minimum Canadian regulatory standards. These evaluations are performed on randomly selected sets of carcasses/products selected throughout the production shift to validate the manufacturer’s food safety and hygienic performance. The establishment's Production personnel, Quality Control personnel, and CFIA’s inspection staff each have a role to fulfill in applying the finished product standards. These responsibilities vary depending on the status of the process. In general, designated establishment personnel (Production or QC) are responsible for performing finished product standards tests as well as taking the appropriate action in response to the results of those tests. Designated CFIA inspectors are responsible for monitoring establishment tests and actions, performing correlation tests and performing periodic independent tests to verify the company’s performance as deemed necessary by the VIC. The VIC or the designated EG 04 supervisor (or equivalent) shall perform all tests/evaluations related to carcass FPS for food safety. Note: CFIA reserves the right to take regulatory corrective action including retention of product when it is determined by the VIC/delegate that the establishment has failed to properly and reasonably apply the HLIS program. The approved carcass population is evaluated for two general categories of defects; 1. Food safety (FS) defects which include identifiable fecal material, identifiable ingesta material and food safety pathological conditions. FS defects shall be evaluated on the basis of colour, texture and consistency and must be clearly identifiable before being scored as such. Generally defects that are < 3.0 mm in their greatest dimension can be difficult to characterize with certainty when using only the naked eye. If the observer is not able to clearly identify a defect as being of FS origin it shall be classified as extraneous or foreign material and scored under the OCD category. 2. Other Carcass Defects which are regarded as unsuitable for consumption or fail to meet regulatory requirements but do not pose a direct food safety risk as well as those defects that do not meet regulatory requirements and also in turn do not pose a significant food safety risk. These two general categories of defects are evaluated on randomly selected sample sets of approved carcasses collected on the slaughter line at a point after all trimming is completed. In certain circumstances and with the approval of the VIC and the Area/National Program Specialists the sample evaluation may be performed on line provided satisfactory trial evaluation of this procedure has been conducted. Defect Classification: Each of the two general categories of defects noted above contain two specific types of defects: 1) Manufacturing/Dressing Defects (MD’s): These are defects that occur during transportation, live handling, stunning and dressing procedures and are to be distinguished from pathological defects or lesions referred to as Trimmable Pathological Conditions ( TPC’s). Refer to Table 7.1. 2) Designated Trimmable Pathological Conditions (TPC’s): Under the HLIS system the operator has full responsibility for the identification and removal of dressing/manufacturing and specified pathological defects as well as the removal of all designated trimmable pathological conditions. These trimmable pathological conditions fall into one of two categories identified as Category I or Category II TPC’s, see Table 7.1. Category I TPC's are to be identified and removed by plant personnel on or off line and do not necessarily require direct CFIA supervision. Category II TPC’s may also be removed on or off line by plant personnel but only after first being identified by CFIA inspectors. Any Category II food safety TPC encountered in a sample set scores as zero tolerance and will require sanitary removal of the defect and may result in the failure of the carcass sample set. Refer to Decision Tree Appendix C to determine next step i.e. status of the associated lot and test mode status. 7.1 Trimmable Pathological Conditions - TPC’s: a) Category I TPC’s are simple isolated resolved pathological or unacceptable anatomical conditions sometimes associated with dressing procedures but which do not affect the disposition of the entire carcass and are assigned to the industry accredited detectors and trimmers for identification and removal. TPC’s include and are limited to bruising >2.5 cm, simple fractures, dry adhesions > 5.0 cm, single tarsal arthritis. b) Category II TPC’s includes all other pathologies and these must first be identified by CFIA personnel and then trimmed by a accredited trimmer on or off line under CFIA supervision. The presence of a Category II TPC in any sample set will require correction for the condition prior to the carcass(es) being released followed by the appropriate corrective action for the lot if applicable. The normal CFIA procedure for Category II TPC’s shall be: i) the head inspection station, if applicable, will place an alert tag/equivalent marking system for further evaluation by viscera/carcass inspectors. ii) carcass/viscera inspector will further evaluate and either direct a designated employee to place a held tag for veterinary disposition, or will allow carcass to continue with alert tag in place. iii) if the carcass is tagged HELD it is retained for Veterinary disposition. If not retained the carcass continues on line with the alert tag in place for removal of condition on line or on the retrim rail by an accredited trimmer.
7.2 CARCASS EVALUATION FOR DEFECTS: 7.2.1 Carcass Evaluation For Food Safety (FS) Defects: The carcass is evaluated for the presence of fecal, ingesta and food safety pathology defects based on ISO sampling plan 2859-1, S-1. The lot or batch size shall be the choice of the facility operator (see definitions) and agreed to by the VIC/Area Program Specialist but must remain within the facilities process control capability. Also included in this plan are associated switching rules which allows the operator to function in "Normal", "Tightened" or "Reduced" sampling mode based on test performance results. ISO switching rules apply. Scheduled random sampling is performed by the facility operator and monitored by CFIA. Refer Appendix C-Decision Tree for Food Safety Defects. Once a lot size category is selected by the operator it may not be switched spontaneously. A written request shall be submitted to the VIC and a mutually acceptable implementation date negotiated. All carcass samples shall be selected at one time (consecutively) if the sample will be examined off line. When selecting carcasses from a moving line random selection principles are applied. Sample size is determined according to the Operator’s ISO status under ISO sampling plan 2859-1 S1(this sample plan is only applicable if the Shewhart Control Chart is applied at the evisceration step) Record all nonconformances on Form CFIA/ HLIS 003S When the test is performed by CFIA and the same form for recording results is shared with the company a different ink colour shall be used to distinguish the CFIA results. Normal Mode: Normal mode is maintained as long as the operator continues to pass at least four out of five consecutive carcass sample set tests. In each carcass sample set the carcasses are examined for food safety defects only. All carcasses shall be examined for food safety defects irrespective of how many defects are observed. Observation of one or more food safety defects will fail the sample set but not necessarily alter the classification of Normal test mode unless this is the second failure within five consecutive tests. See section 7.2.2 Corrective Actions. Tightened Mode: Tightened mode is maintained until the operator has passed five consecutive satisfactory tests. In each carcass sample set the carcasses are examined for food safety defects only and all carcasses in the set shall be examined irrespective of how many food safety defects are noted. Five consecutive satisfactory sample sets must be achieved before returning to Normal Mode. See Section 7.2.2 Corrective Actions Reduced Mode: Reduced mode is presently an elective category and the operator may decline if s/he so chooses and is achieved after 10 consecutive satisfactory tests in Normal mode. The operator must perform without any defects being observed in any carcass sample sets while in Reduced mode or s/he shall return to Normal mode. All carcasses in the sample set shall be examined for food safety defects irrespective of the number of defects found. See Sec 7.2.2 Corrective Actions. 7.2.2 Corrective Actions for Food Safety Defects: Refer Appendix C-Decision Tree for Food Safety Defects FS Action Limits: Single Site GIT (gastro-intestinal tract) Defect {BEEF ONLY} {Carcasses in a stationary sample set which exhibit no more than1defect per carcass ˜ 5 mm in its greatest dimension and originating from the GIT shall not be scored. The defect shall be removed sanitarily before the carcasses are released. Any carcasses displaying more than one such defect, irrespective of size, OR one or more defects of another FS category shall be scored in accordance with the HLIS Program requirements and all process actions will apply. This action limit exemption does not apply to any carcasses that are evaluated and scored while on a moving carcass line.} Normal Mode: Under normal mode a lot failure occurs whenever there is a failure of more than one out of five consecutive carcass sample sets. When this occurs only the current production lot shall be detained and reworked for any food safety defects that caused the lot failure. The Operator shall then move into "Tightened" testing mode on the next sample test. Tightened Mode: Under tightened mode five consecutive sample sets must pass to return to Normal mode. When entering Tightened mode if the first test fails the affected lot shall be detained and reworked as above. While in Tightened mode any test failure requires rework of the affected lot. (See Rework 7.4) Reduced Mode: A lot failure occurs in this mode upon the first failed test of a sample set and the associated lot is identified for rework. A reduction in status to Normal Mode also occurs at the next scheduled test. Note: Any defects noted during the evaluation shall be sanitarily removed before the carcass is released. Particulate material < 3.0 mm in size that cannot be clearly or readily identified as GIT contamination using the normal criteria of texture, color and appearance will be treated as extraneous material. 7.2.3 Carcass Evaluation For Other Carcass Defects (OCD): The carcass is evaluated for other carcass defects which are defects that do not pose a direct food safety concern such as bruises, fractures, adhesions, hair, failed regulatory requirements such as presence of mammary tissue, untrimmed stick wound etc. When testing for these criteria generally about 1% of the carcass population is randomly sampled by the operator and monitored by CFIA. The carcass sample size shall be determined by the VIC and Area Program Specialist based on the above criteria. Refer Appendix B-Decision Tree for Carcass Non Food Safety Defects. Reduced testing frequencies may occur in this category based upon operator performance. Regular Mode: The operator shall perform carcass tests for other carcass defects on each production lot during each production shift. The choice of frequency will be correlated to the operator’s defined lot size (1.0 hour of production or 0.5 hour of production). See Table 7.2.These tests shall be performed on a random basis and may be conducted at the same time as the food safety defect test. Relaxed Mode: After ten (10) consecutive successful test scores the operator may elect to move into Relaxed testing mode. The same number of carcasses shall be tested but at a lowered frequency. See Table 7.2. Any test failure will return the operator to Regular mode. When taking samples all carcasses shall be selected at one time if the sample is to be examined off line. When selecting carcasses from a moving line random selection principles shall be used and consecutive sample units shall be collected. The nonconformance results for the sample units are to be recorded and scored on Form CFIA/ HLIS 002S. When the test is performed by CFIA and the same form is shared with the company a different ink colour shall be used to distinguish the CFIA results. After performing a CFIA correlation test the inspector shall compare the test score with the establishment's results. If results are not in agreement an additional correlation test shall be performed. In the event of a second non matching score CFIA test results shall be officially recorded as the correct result and appropriate process actions initiated (if applicable) by the operator. The VIC and the Operator shall collaborate to determine the reason for the non correlation. The CFIA inspector shall also evaluate appropriate plant records for timeliness, completeness, and accuracy at the preselected random times and correlate the results with the appropriate establishment representative. 7.2.4 Corrective Actions for Other Carcass Defects: Upon failing any FPS test for OC defects whether in Regular or Relaxed mode the operator shall immediately identify and hold for rework only the immediate production lot associated with the test failure. If the operator was in Relaxed testing mode he shall return to Regular testing mode. Ten consecutive successful test scores shall be achieved before returning to Relaxed mode. The affected lot shall be reworked for the defect(s) that were identified in the failed test score. 7.2.5 CFIA/Operator Testing Frequency: All correlation checks performed by the CFIA monitor will be selected on a random time basis. More than one check per shift or half shift may be performed if there is concern regarding test results. The VIC/delegate shall approve any additional testing.
7.3 SCORING CARCASS DEFECTS: 7.3.1 Food Safety Defects The following defects have a zero tolerance. For those defects that may be questionable as to origin and are < 3.0 mm in their greatest dimension please refer to section 7.0 for additional criteria.
All defects food safety defects that are observed while examining a sample set shall be sanitarily removed before the sample set is released. All findings shall be recorded on form CFIA/ HLIS 003. Refer to Appendix C Decision Tree for Food Safety Defects. 7.3.2a Other Carcass Defects: SWINE ONLY see Table 7.3: i) STAINS: Bile, oil etc.; Minor defect ii) BLOOD CLOTS: Clots iii) BRUISING: Bruises iv) EXTRANEOUS MATERIAL: Minor defect; v) HAIR (scalded carcass) Minor defect; obvious bristle/hair in an area vi) MUTILATION (equipment/live handling related prior to evisceration) Includes complete break in the skin: minor defect > 5.0 cm and vii) SCAR TISSUE/ADHESIONS: Defects smaller or equal to 5.0 cm are not scored. Minor defect; > 5.0 cm and viii) IMPROPER TRIM / ORGAN REMNANTS Defects ix) TOE NAILS / INTERDIGITIAL GLANDS: Minor defect; one toe nail/gland not removed. Major defect; > 1 toe nail/gland not removed x) FRACTURES/Category I TPC: Any recent fractures or fractures that have failed to heal and pose a consumer unsuitability condition or any unremoved Category I TPC. Major defect. xi) STICK WOUNDS Major defect: untrimmed in part or in whole. xii) SKIN CONDITIONS Unmarked skin defects (Urine burn, seedy belly etc.) Minor defects; area of skin > 5 cm2 and xiii) MAMMARY TISSUE - non lactating Minor defect; Notes: 1. All dry adhesions < 5.0 cm, localized hyperemic skin conditions, resolved scar tissue/fractures and small bone fragments/fractures created during dressing procedures are disregarded and not scored as a non-conformance and do not normally require trimming unless associated with unsuitable hemorrhage/bruising etc. 2. Scoring Rules; for each major defect score 1, to convert minor to major X minor score by 0.2 (except mammary tissue, organ remnants, toenails which are multiplied by 0.5). Accept lot with a total of 2.9, reject lot with a score of 3.0 or greater. Do not round decimal values up or down while adding score.
7.3.2a Other Carcass Defects: BEEF ONLY see Table 7.4 i) STAINS: Bile, oil etc; minor defect; ii) BLOOD CLOTS: Clots less than 4.0 cm not scored. Minor defect; > 4.0 cm and iii) BRUISING: Bruises iv) EXTRANEOUS MATERIAL: Minor defect; v) PARASITES/INSECTS: Minor defect; each insect, warble etc. 5 minors accumulate to one major. vi) FRACTURES/CATEGORY I TPC Any recent fractures or fractures that have failed to heal and pose a consumer unsuitability condition or unremoved Category I TPC. Major defect vii) HAIR Minor defect; 5-10 strands in a single 50 cm2 area. Major defect; >10 strands in a 50 cm2 area. Five minors accumulate to 1 major. viii) HIDE Minor defect; ix) MAMMARY TISSUE - non lactating (see note below). Minor defect; x) ORGAN REMNANT/IMPROPER TRIM (see note below) Less than 5.0 cm not scored. Minor defect >5 cm and xi) SCAR TISSUE/ADHESIONS
xii) STICK WOUNDS Major defect: untrimmed in part or in whole. Note: For each major defect score 1, to convert minor defects to major defects, # minors x 0.2 (except mammary and organ remnants are multiplied by 0.5). Accept a lot with total of 6.9, reject with a total score of 7 or greater. Any lactating mammary tissue will be classified as a Category II TPC with a zero tolerance.
7.4 REWORK OF FAILED LOT(S) i) Establishment Responsibilities and Actions: Specific lots of product retained for rework may, at the discretion of the establishment, be reworked as the original lot(s) or be subdivided into smaller lots of carcasses. Once the specified lot has been reworked for the appropriate defects one standard sample set of three (3) carcasses will be randomly selected for each 100 carcass lot reworked. A lot of less than 100 carcasses shall have a minimum sample size of three (3) carcasses with a minimum lot size of 25. Lots exceeding 100 carcasses shall have their sample numbers prorated according to their lot size, eg. 150 carcasses would require a minimum of 4 carcasses, 175 would require 5 carcasses, 200 would require 6 carcasses etc. Samples of reworked product that are presented for re-inspection must be randomly selected from the lot’s declared population. Refer to Appendix E Decision Tree for Carcass Rework. The establishment shall randomly select a sample set from throughout the lot and achieve a satisfactory test result before releasing it for further processing. If the lot was detained for rework because of an FS defect the sample set shall be examined for those FS defects only (ANY other encountered defect, FS or OCD, shall be sanitarily removed). The lot shall be released if no FS defects are found in any of the sample units. The lot shall be detained and reworked again if any of the FS defect(s) that failed the lot are found. If the lot was detained for rework for other carcass defects, the lot shall be examined and corrected for the specific non-conformance(s) which initiated the process control action. Once the lot is reworked it shall be sampled and evaluated as described above and released or reworked in accordance with the sample findings. ii) CFIA Responsibilities and Actions:
7.4.1 Voluntary Rework Under Extra Ordinary Circumstances Due to extra ordinary circumstances beyond the operator’s immediate control certain groups of carcasses may be presented with conditions on the evisceration floor that significantly bias that group towards failure of the performance standards for Finished Product Testing. In such circumstances and at the discretion of the VIC, the operator may request that such a group of affected carcasses be exempted from Finished Product Standards Testing provided that the operator agrees to properly identify and retain the affected group for rework as described in section 7.4 and the exempted group of carcasses poses no food safety concerns and an approved written procedure has been established for the handling of such hogs in the company’s written program and/or HACCP plan.
Rules : 1. Regular mode shall be used to start 2. Regardless of which inspection mode is being used, all defects are removed from the sample before it is released and all units in the sample are examined 3. Irrespective of mode, Regular or Relaxed, only the immediate associated lot shall be reworked when a failure occurs ie. ½ hour of production for swine and 1 hour of production for beef.
Rules 1. Normal mode shall be used to start 2. Normal, tightened or reduced modes shall continue unchanged except where indicated by the decision tree above; 3. Regardless of which inspection mode is being used, all carcass defects shall be removed from the sample set before it is released and ALL carcass units in the sample are examined. 4. Retests shall be performed every 15 or 30 minutes as per operator’s written program
Rules : 1. Testing in normal, tightened or reduced modes shall continue unchanged except where indicated by the decision tree. 2. A sample unit (viscera, head or carcass) fails if one or more attributes are scored. 3. There is a maximum of one failure per sample unit. 4. There shall be no more than one process control step under a line speed reduction at any given time.
Rules : 1. All encountered defects, Food Safety or Other Carcass Defects shall be sanitarily removed from all carcasses in the sample. 2. The failed lot shall be reworked for all contributing defects if encountered in the failed score. 3. Unless otherwise specified a lot consists of ( ½ hour of production for swine and 1 hour of production for beef), irrespective of the mode category. 4. The operator may select sub lots for purposes of rework as per the HLIS policy. Forms CFIA/ HLIS 001 to 007 not available on Internet - forms may be obtained from any CFIA Inspector |
