Prevalence of Listeria in Smoked Fish.

ABSTRACT

Smoked fish samples (71) were surveyed from Newfoundland retail markets and tested for the prevalence of Listeria . Staphylococcus aureus and fecal coliforms were also detected in the samples. Listeria was present in 11.3% of the smoked seafood products; 4 smoked cod, 3 smoked mackerel, and 1 smoked caplin were found to harbor the bacterium. The Food and Drug Administration protocol was also analyzed with regards to testing smoked seafoods. The secondary enrichment broth showed a 68% false-positive rate, whereas all positive samples were detected after 24 h of primary enrichment.
