Summary

Rainbow trout samples (n= 74), purchased at 31 retail markets, were surveyed for the presence of Listeria. Samples were direct plated and enriched in accordance with USDA and FDA protocols. From the results, it was apparent that Listeria species were frequently present in fresh trout. Ninety percent of the fresh retail trout samples having a coliform count of log 5.0 CFU/g or higher were positive for Listeria. Optimal recovery of Listeria species in trout was obtained by use of multiple enrichment and plating media.
