Presence, detection and growth of Listeria monocytogenes in seafoods: a review

Abstract

Listeria monocytogenes and other Listeria spp. have been isolated from seafoods on a regular basis since 1987. A relatively high incidence of the organism (6-36%) in ready-to-eat cold smoked salmon and cooked fish products has raised concern about the survival and growth potential of this organism in seafoods, as these products are not processed further before consumption. L. monocytogenes grows well at refrigeration temperature on most seafoods, but the sources of contamination in ready-to-eat fish products are still unknown. This paper reviews the knowledge available in order to make recommendations on control options and avenues for future research.
