ABSTRACT
From September to December 1994, 130 samples of aquatic food imported from mailand China were collected from Taipei wholesale center and Lien Chiang county retail markets, and screened for Vibrio parahaemolyticus. The overall incidence was 16.9 %. Incidence for clam, shrimp and fish was 50.0 %, 25.0 % and 14.9 %, respectively. For samples collected from Lien Chiang county retail market, the incidence of Vibrio parahaemolyticus was significantly higher than from Taipei wholesale center ( p=0.001 ). For enrichment media, no significant difference (p=0.871 ) was found between alkaline peptone salt broth and glucose salt teepol broth.
