Vol. 138, No. 45 — November 6, 2004 Regulations Amending the Food and Drug Regulations (1413 — Dimethomorph)Statutory authority Food and Drugs Act Sponsoring department Department of Health REGULATORY IMPACT (This statement is not part of the Regulations.) Description Dimethomorph is registered under the Pest Control Products Act as a fungicide for the control of late blight on potatoes. By virtue of subsection B.15.002(1) of the Food and Drug Regulations, the Maximum Residue Limit (MRL) for residues of dimethomorph in any food is 0.1 parts per million (p.p.m.). The Pest Management Regulatory Agency (PMRA) of Health Canada has recently approved an application for the registration of a new end-use product containing the active ingredient dimethomorph for the use mentioned above. Following the review of data submitted in connection with this application, this proposed regulatory amendment would establish an MRL for residues of dimethomorph resulting from this use on potatoes, in order to permit the sale of food containing these residues. In order to determine whether proposed MRLs are safe, the PMRA conducts a dietary risk assessment. An acceptable daily intake (ADI) and/or acute reference dose (ARfD) is calculated by applying a safety factor to a no observable adverse effect level or, in appropriate cases, by applying a risk factor which is calculated based on a linear low-dose extrapolation. The potential daily intake (PDI) is calculated from the amount of residue that remains on each food when the pest control product is used according to the proposed label and the intake of that food from both domestic and imported sources in the diet. PDIs are established for various Canadian subpopulations and age groups, including infants, toddlers, children, adolescents and adults. Provided the PDI does not exceed the ADI or ARfD for any subpopulation or age group, and the lifetime risk is acceptable, the expected residue levels are established as MRLs under the Food and Drugs Act to prevent the sale of food with higher residue levels. Since, in most cases, the PDI is well below the ADI and lifetime risks are very low when MRLs are originally established, additional MRLs for the pest control product may be added in the future. After the review of all available data, the PMRA has determined that an MRL for dimethomorph of 0.01 p.p.m. in potatoes would not pose an unacceptable health risk to the public. Alternatives Under the Food and Drugs Act, the sale of food containing residues of pest control products at a level less than or equal to 0.1 p.p.m. is permitted unless a lower MRL has been established in Table II, Division 15, of the Food and Drug Regulations. In the case of dimethomorph, establishment of an MRL for potatoes is necessary to support the additional use of a pest control product which has been shown to be both safe and effective, while at the same time preventing the sale of food with unacceptable residues. Benefits and costs The use of dimethomorph on potatoes will provide joint benefits to consumers and the agricultural industry as a result of improved management of pests. In addition, this proposed regulatory amendment will contribute to a safe, abundant and affordable food supply by allowing the importation and sale of food commodities containing acceptable levels of pesticide residues. Some costs may be incurred related to the implementation of analytical methods for the analysis of dimethomorph in the food mentioned above. Resources required are not expected to result in significant costs to the Government. Consultation Registration decisions, including dietary risk assessments, made by the PMRA are based on internationally recognized risk management principles, which are largely harmonized among member countries of the Organisation for Economic Co-operation and Development. Individual safety evaluations conducted by the PMRA include a review of the assessments conducted at the international level as part of the Joint Food and Agriculture Organization of the United Nations/World Health Organization Food Standards Programme in support of the Codex Alimentarius Commission, as well as MRLs adopted by other national health/regulatory agencies. Compliance and enforcement Compliance will be monitored through ongoing domestic and/or import inspection programs conducted by the Canadian Food Inspection Agency when the proposed MRL for dimethomorph is adopted.
