摘要

Consumption of raw oysters has been linked to several outbreaks of Vibrio parahaemolyticus infection in the United States. This study investigated effects of ice storage and UV-sterilized seawater depuration at various temperatures on reducing V. parahaemolyticus in oysters. Raw Pacific oysters (Crassostrea gigas) were inoculated with a mixed culture of five clinical strains of V. parahaemolyticus (10290,10292,10293, BE 98-2029 and 027-1 c1) at levels of 10~(4-6) MPN/g. Inoculated oysters were either stored in ice or depurated in recirculating artificial seawater at 2,3, 7,10,12.5, and 15℃ for 4-6 days. Holding oysters in ice or depuration of oysters in recirculating seawater at 2 or 3℃ for 4 days did not result in significant reductions (P > 0.05) of V. parahaemolyticus in the oysters. However, depuration at temperatures between 7 and 15℃ reduced V. parahaemolyticus populations in oysters by >3.0 log MPN/g after 5 days with no loss of oysters. Depuration at refrigerated temperatures (7-15℃) can be applied as a post-harvest treatment for reducing V. parahaemolyticus in Pacific oysters.
