Analysis on the status of Vibrio parahaemolyticus contamination in animal freshwater products sold in Guangzhou

Objective To investigate the contamination level of Vibrio parahaemolyticus (VP) in the freshwater products in Guangzhou. Methods Nine hundred and sixty-six samples of the freshwater products were collected for VP detection from 2006 to 2019 according to the food safety risk monitoring of national, provincial and municipal project. Results Two hundred and eleven samples were detected positive of VP out of 966 samples, with an overall positive rate of 21.84%. The detection rate was significantly different in different seasons, sampling positions, species and processing methods and selling styles. The detection rate of VP (27.40%) was the highest in the third quarter of a year. The detection rate of VP (32.73%) was the highest in supermarkets of all sampling positions. The detection rate of VP (53.33%)was the highest in the freshwater crab of all species. The detection rate of VP (27.23%) was the highest in the fresh freshwater products of all kinds. Conclusion The freshwater products had been contaminated with VP in Guangzhou. The government should integrate management throughout the food chain to prevent contamination, and carry out health education and the early risk warning of food safety.
