A study was carried out in order to reduce the hygienic bacteria from sea urchin Strongylocentrotus nudus viscera. The effect of pre-culturing before shipment using electrolyzed seawater on reduction of Vibrio parahaemolyticus and viable bacteria inhabiting the sea urchin viscera was examined. When 3% salt water suspended with V. parahaemolyticus was electrolyzed, the viable number of V. parahaemolyticus was reduced by more than 99.99% after treatment with 0.23 mg/L chlorine for one minute. In the case of sea urchin reared with electrolyzed seawater containing O.76 mg/L chlorine for 2 days, a lot of dejecture was discharged, and the bacteria in the sea urchin viscera were reduced by more than 90%.
