Call for data: Request for scientific data and information on Shiga toxin-producing Escherichia coli in various food commodities

Current status: Closed

Opened on July 23, 2021 and will close November 12, 2021

Health Canada has begun the development of a risk analysis on Shiga toxin-producing Escherichia coli (STEC) (also known as Shigatoxigenic E. coli and verotoxin-producing E. coli (VTEC)) in various food commodities. This work will review information related to STEC in various food commodities in Canada and examine current food safety approach. The main objective of this work is to support Health Canada’s guidance to industry and regulatory authorities regarding the identification and mitigation of STEC in food and continue to protect the Canadian population from foodborne illnesses.

Goals of this call for data

Health Canada is issuing a call for data to help identify the factors that may have an impact on the presence of STEC in various food commodities and to identify potential mitigation strategies in the production, distribution and consumption of such products. The risk analysis will also examine microbiological methods for isolation and identification of STEC in use across the production and distribution continuum.
