The efficacy of a flow-through depuration system in eliminating the human pathogen Vibrio vulnificus from eastern oysters ( Crassostrea virginica ) collected from the North Gulf of Mexico coast was evaluated in this study. Depuration experiments were conducted with artificially inoculated oysters using laboratory-grown strains of V. vulnificus as well as with naturally contaminated oysters. Determination of V. vulnificus numbers in oyster tissues was conducted at 0, 1, 2, 3 and 6 days of depuration. Results showed that the depuration of V vulnificus is possible using a flow-through system. Numbers of V. vulnificus in laboratory-inoculated oysters were reduced from >100,000 Most Probable Number (MPN)/g of oyster tissue to 23 MPN/g after six days of depuration. As expected depuration results of naturally contaminated oysters were more variable. Depur.. View More»
