Abstract:Objective To understand Vibrio parahaemolyticus and Vibrio vulnificus contamination in raw ready-to-eat (RTE) aquatic products. Methods Using the principle of random sampling, 2 980 samples of raw RTE aquatic products were collected from restaurants, retail stores and wholesale markets in 13 regions of China, to monitor the contamination status of Vibrio parahaemolyticus and Vibrio vulnificus. Results The detection rate of Vibrio parahaemolyticus was 14.7%(437/2 980), the proportion of samples with >100 MPN/g was 2.9%(83/2 909), and the detection rate of Vibrio vulnificus was 3.5%(104/2 980). The detection rate of Vibrio parahaemolyticus, the proportion of samples >100 MPN/g and the detection rate of Vibrio vulnificus in samples from wholesale markets were higher than those from restaurants and retail stores. The detection rate of Vibrio parahaemolyticus, the proportion of samples with >100 MPN/g, and the detection rate of Vibrio vulnificus were the highest in the third quarter. The main causes of contamination included pollution in source areas, improper storage conditions and cross-contamination during processing. Conclusion There were Vibrio parahaemolyticus and Vibrio vulnificus contamination in raw RTE aquatic products, and its risk to health deserved enough attentions.
