Present situation in Canada regarding Listeria monocytogenes and ready-to-eat seafood products

The present situation regarding Listeria monocytogenes and ready-to-eat (RTE) seafood is discussed. An updated regulatory policy on L. monocytogenes directs inspection and compliance action to those RTE foods capable of supporting growth of the organism and is based on a combination of inspection, environmental sampling and product testing. The incidence of L. monocytogenes in imported seafood products in 1996–1997 and 1997–1998 was 0.88 and 0.3%, respectively. With respect to domestic products, an analysis of 347 RTE foods in 1997–1998 and 1998–1999, at one of the large fish inspection labs in the Maritimes, revealed an absence of L. monocytogenes. The only seafood product linked to suspect cases of listeriosis in Canada was imported.
