The 2023 Listeria policy, which replaces the 2011 version, was developed by Health Canada, with input from the Canadian Food Inspection Agency (CIFA) and the Public Health Agency of Canada, and takes into account the roles and responsibilities of industry, government, and consumers. The Listeria policy is intended to assist in the application and verification of activities for L. monocytogenes in ready-to-eat (RTE) foods. Its implementation should permit the early identification of the persistence of Listeria species in the food processing environment and allows for the assessment of the effectiveness of control measures put in place to address L. monocytogenes in RTE foods.
