   One hundred and twenty Sashimi samples obtained from traditional markets, supermarkets and other retail outlets in the Taipei area from September 1994 to January 1995 were screened for Vibrio parahaemolyticus. The total incidence was 13.3 % (< 0.08~0.56 MPN/g); broken down by traditional markets, supermarkets, and others, incidence was 23.1 %, 0 %, and 17.1 % respectively. The incidence of V. parahaemolyticus from supermarkets was significantly lower than that from traditional markets and other sources. However, no significant difference was found in occurrence rate between samples from supermarkets and samples from other sources. Raw fish fillet samples showed a higher incidence than miscellaneous samples. When enrichment media were used, no significant difference was observed between alkaline peptone salt broth and glucose salt teepol broth.
