Objective To investigate the contamination level and trend of Vibrio parahaemolyticus(VP) in freshwater products in Jiangsu Province, and provide basic quantitative data for the risk assessment. To grasp the contamination level and trend of Vibrio parahaemolyticus (VP) in freshwater products in Jiangsu Province, and provide basic quantitative data for the risk assessment. Methods One thousand one hundred and seventy samples form 8 categories freshwater products were collected from 2010 to 2018. The sampling sites include different locations of circulate and catering links in 13 cities of Jiangsu Province. The qualitative and quantitative data was obtained by method based on GB 4789.7 “Food microbiological examination-Examination of Vibrio parahemolyticus”. @RISK software was used to analyze the data and fitting quantitative contamination data. 1170 samples form 8 categories freshwater products were collected from 2010 to 2018. The sampling sites include different locations of circulate and catering links in 13 cities of Jiangsu Province. The qualitative and quantitative method based on GB 4789.7 “Food microbiological examination-Examination of Vibrio parahemolyticus”. Use @RISK software analyze the data and fitting quantitative contamination data.Results The detection rate of VP in 1 170 freshwater products was 28.0% and 3.7% VP carried virulence gene. The contamination levels of VP in freshwater products was (-1.01±1.57) lg MPN/g. The detection rate and contamination levels of VP in inland areas was higher than coastal areas, the difference was statistically significant (P<0.05). The difference of detection rates and contamination levels in different years, areas, categories, months and quarters were statistically significant (P<0.05). While the difference in different sampling sites was not statistically significant (P>0.05). The contamination levels of VP in inland areas and coastal areas were (-0.89±1.59) lg MPN/g and (-1.56±1.54) lg MPN/g. The contamination level in the second quarter, in the restaurant/hotel and freshwater shrimps were the highest, with the values of (-0.56±1.72) lg MPN/g, (-0.68±1.55) lg MPN/g and (-0.44±1.68) lg MPN/g, respectively.

The contamination levels of VP in inland areas and coastal areas were -0.89±1.59 lg MPN/g and -1.56±1.54 lg MPN/g.

The values were -0.56±1.72 lg MPN/g, -0.68±1.55 lg MPN/g and -0.44±1.68 lg MPN/g, respectively.Conclusion The contamination of VP in freshwater products in Jiangsu Province was seriously. The contamination of VP had shifted from seafood to freshwater products and spread from coastal areas to inland areas. Moreover, the contamination of inland area had a trend to exceed the coastal areas. Freshwater products might be the important risk factor for the disease of VP. The contamination of VP in freshwater shrimps were seriously. It is necessary to carry out the risk assessment for freshwater products.
