FoodNet Canada:
The integrated sentinel site surveillance network for enteric disease in Canada.
- Last updated: 2024-10-29
FoodNet Canada's interactive data visualizations provide an overview of surveillance data since 2015 by:
- enteric pathogen
- sentinel site
- surveillance component (i.e., human cases, farm animal, retail food, and water)
- incidence rate or prevalence
The interactive visualizations are updated regularly, and therefore may differ from published FoodNet Canada reports.
Please contact FoodNet Canada with any additional questions about our data, or to submit a formal data request if you plan to publish these data or require additional data.
For additional information, please visit the Public Health Agency of Canada's FoodNet Canada webpage.
The COVID-19 pandemic resulted in several disruptions to FoodNet Canada surveillance activities from 2020 to 2022. The Quebec sentinel site was implemented in July 2019. For further details, please refer to figure footnotes.
Definitions
Sentinel site: A sentinel site is a community from which in-depth data are gathered and used to inform programs and policies affecting a larger geographic area. Sentinel sites generate results that are representative of the broader population.
Case classifications:
- Endemic
- Endemic cases of disease are affected individuals who had an infection that was considered sporadic and domestically acquired (i.e., within Canada).
- Lost to follow-up (LTF)
- Includes cases that could not be followed up with an interview by public health.
- Non-endemic
- Includes immigration-related cases where illness was acquired outside of Canada.
- Outbreak
- Outbreak-related cases of disease are one of a number of affected individuals associated with an increased occurrence of the same infectious disease, whose illness is confirmed through a public health partner (British Columbia, Alberta, Ontario, and Quebec sentinel sites) on the basis of laboratory and/or epidemiological evidence.
- Travel
- Travel-related cases of disease (excludes non-endemic cases) are individuals who travelled outside of Canada, and where the travel dates overlap with the expected disease incubation period (varies depending on the pathogen).
Abbreviations:
- FBCP
- Frozen breaded chicken products
- IR
- Incidence rate
- STEC
- Shigatoxigenic E. coli
Figure 1. FoodNet Canada human enteric disease incidence rates per 100,000 population
Combined sites include the following sentinel sites: British Columbia (Fraser Health), Alberta (Alberta Health Services: Calgary and Central Zones), Ontario (Middlesex-London Health Unit) and Quebec (Région sociosanitaire de la Montérégie). If the 'Combined sites' option is selected, all available site data will be included in this trendline.

Combined sites includes the following sentinel sites: British Columbia (Fraser Health), Alberta (Alberta Health Services: Calgary and Central Zones), Ontario (Middlesex-London Health Unit) and Quebec (Région sociosanitaire de la Montérégie). If the 'Combined sites' option is selected, all available site data will be included in this trendline.
No data is available for the current selection.
| Case classification | Incidence rate per 100,000 population | Proportion (%) |
|---|---|---|
| Total incidence rate |
For pathogens with low total incidence rates, case classification proportions should be interpreted with caution due to low case counts.

Combined sites include the following sentinel sites: British Columbia (Fraser Health), Alberta (Alberta Health Services: Calgary and Central Zones), Ontario (Middlesex-London Health Unit) and Quebec (Région sociosanitaire de la Montérégie). If the 'Combined sites' option is selected, all available site data will be included in this trendline.
There are data points that overlap since they have the same value. Please see the text description below to see all data.
