In China neighboring countries, rapid economic growth has encouraged increased seafood, dietary habits are changing, more people eating fish. this study, the prevalence V. was investigated 48 samples from 11 species live seafood available markets coastal cities China. The detected four razor clam samples, seven giant tiger prawn five nine mantis shrimp samples. also found water aquaria at markets. maximum level 3.4 log CFU/g 4.9 by direct spreading method. Differential bacterial counts on body revealed that most bacteria were shells (exoskeletons), very few edible muscle. However, dense populations can be intestines. Biochemical tests indicated isolates biotype 1 strain, which pathogenic to humans. These susceptible ampicillin, penicillin, kanamycin, streptomycin, erythromycin. results suggest potential health hazard consuming handling shellfish, especially prawns.
