2 Outline Background and ra2onale Objec2ves Methodology Results Next steps 2

3 Background and ra>onale Na2onal food exposure data for outbreak response do not exist» Currently use 7 year old data from the U.S. and one regional study in Ontario» Nutri2on focused surveys do not meet these data needs 3

4 Objec>ves To establish a database describing Canadians exposure over a seven day period to foods that may serve as vehicles of foodborne infec2on to inform 2mely and effec2ve enteric illness outbreak response To determine sources of enteric illness in Canada, suppor2ng risk assessments and help to target public health interven2ons to prevent illness To inform the burden of foodborne and waterborne illness es2mates in Canada To use consump2on paperns, consumer behaviour, health-related informa2on, and socioeconomic status indicators to inform food safety educa2on ini2a2ves and health promo2on efforts linked to obesity and determinants of health 4

10 Foodbook data for outbreak response Rapid access to general popula2on exposure data will help guide outbreak response» This will help build the weight of evidence required to support the 2mely removal of contaminated food source(s) from the marketplace Examples of use in recent mul2-jurisdic2onal outbreak inves2ga2on: S. Enteri2dis in breaded chicken products» Approximately 70% of cases reported exposure to breaded chicken products, compared to <20% of Foodbook respondents 10
