Refrigerated seawater depuration for reducing Vibrio parahaemolyticus contamination in raw Pacific oysters (Crassostrea gigas)

Creator:

Yang, Qianru

Abstract:

Vibrio parahaemolyticus is a seafood-borne pathogen that can cause gastroenteritis in humans. This study investigated the effectiveness of refrigerated seawater (5°C) depuration on reducing V. parahaemolyticus in raw Pacific oysters (Crassostrea gigas). Raw Pacific oysters were inoculated with a mixed culture of five clinical strains of V. parahaemolyticus and depurated...

Duan, Jingyun

Abstract:

Distribution of Vibrio parahaemolyticus in Oregon and Washington oystergrowing areas was studied between November 2002 and October 2003. V. parahaemolyticus was detected in 14.3% of oyster, 23.0% of seawater, and 44.4% of sediment samples with very low levels (≤7.4 MPN/g) of pathogenic strains being detected in oysters. Occurrence of V....
