Pilot-scale depuration demonstrates the suitability of non-pathogenic Vibrio parahaemolyticus as a surrogate for commercial-scale validation studies.

ABSTRACT: Shellfish producers have proposed using depuration systems to reduce Vibrio parahaemolyticus levels by supporting the oysters' natural purging ability. For commercial viability, depuration efficacy must be validated in relevant species and at scale using appropriate conditions, including time and temperature. This study aims to I) compare depuration efficacy across oyster species, II) assess non-pathogenic V. parahaemolyticus as a surrogate, and III) optimize pilot-scale depuration to identify process variables likely to achieve >3.0-log reduction of V. parahaemolyticus at commercial-scale. Three oyster species (Crassostrea gigas, Crassostrea sikamea, Crassostrea virginica) were exposed to artificial seawater (35 ppt) containing five non-pathogenic or five pathogenic V. parahaemolyticus st
