Volume: 24S5 - September 1998
Canadian Integrated Surveillance Report for 1995 on
Salmonella,
Campylobacter and Pathogenic Escherichia coli
Prepared by the
Division of Foodborne and Enteric Diseases
Bureau of Infectious Diseases
Laboratory Centre for Disease Control
Health Protection Branch
Health Canada
This report was developed as part of a pilot project that used Salmonella
as a model agent to evaluate current enteric disease surveillance databases
and develop a more integrated approach to presenting information from
these systems. A survey of information needs of surveillance data users
across Canada was conducted to determine what information was most important
and what format was most acceptable to them. The content and presentation
of Salmonella surveillance data reports from other countries were
also surveyed prior to development of this report.
The data used in this report are from 1995, which was the most recent
year for which complete and verified data were available from the data
sources. The report includes summary information on Campylobacter
and pathogenic Escherichia coli in addition to Salmonella. The
data for human cases are from the National Notifiable Diseases (NND) databases
(Summary and Individual Case) and the National Laboratory for Bacteriology
and Enteric Pathogens (NLBEP) database; data for non-human isolates are
from the NLBEP and Health of Animals Laboratory (HAL) - Guelph (Appendix
A). Other details regarding the cases and isolates in the report can be
found in the annual reports from the sources listed above. These data,
from passive surveillance systems, are useful for evaluating trends and
relative levels of burden of disease but must be interpreted with caution,
given the potential differences in reporting practices between geographic
areas and across time.
Any comments or suggested changes concerning this report can be sent
to Dr. Jeff Wilson, Chief of Foodborne and Enteric Diseases, Bureau of
Infectious Diseases, LCDC, HPB, at the following: jwilson@ovcnet.uoguelph.ca

Veterinary College, University of Guelph, Guelph, ON N1G 2W1.
Acknowledgements
This report would not have been possible without the dedication and hard
work of personnel from across Canada. Local inspectors, public and private
health workers, and public and private laboratory personnel collected
the initial samples and data. Provincial, territorial and federal personnel
ensured that the samples and data were handled appropriately to be included
in the national databases. The cooperation of personnel from Laboratory
Centre for Disease Control (LCDC), Bureau of Infectious Diseases and Bureau
of Microbiology (NLBEP), and from HAL - Guelph was essential for generating
this report. We would like to thank, in particular, Dr. Frank Pollari and
Dr. Christine Powers for the major contribution they made in compiling
and analyzing the submitted data, and in writing this document.
