Abstract：Semi-quantitative risk assessments of Vibrio parahaemolyticus from different seafood were carried out by Risk Ranger software. The data used in semi-quantitative risk assessments were acquired from investigations of V. parahaemolyticus in shellfish. In addition, papers on the contamination status of V. parahaemolyticus from seafood including fish, crustaceans and shellfish were also used as reference. The risk rank values of V. parahaemolyticus in fish, crustaceans and shellfish were 48, 49 and 59, respectively. The risk level of V. parahaemolyticus in fish was moderate   while the risk level of V. parahaemolyticus in crustaceans and shellfish were both high , and the risk level in shellfish was significantly higher than that in fish or crustaceans. The results indicated that quantitative risk assessment of V. parahaemolyticus from shellfish should be given priority  under the circumstance of limited resources.
