The fate of Listeria monocytogenes on packaged, refrigerated, and frozen seafood was determined. Fish and shrimp were inoculated with L. monocytogenes, packaged by one of three treatments (film overwrap or 2 vacuum packaging treatments), and stored either on ice for 21 d or at −20°C for 3 months. No increase in the L. monocytogenes population on iced products was noted regardless of the type of packaging. Populations on frozen products decreased by less than 1 log after 3 months. Vacuum packaging of chilled fish and seafood in the material evaluated may be an alternative packaging treatment.
