目的了解广州市生食水产品副溶血性弧菌(Vibrio parahaemolyticus,VP)污染水平,为生食水产品VP监测工作提供依据。方法在全市12个区的餐饮单位、批发市场、肉菜市场、超市和零售店等场所分季节采集485份不同种类生食水产品样品开展VP检测。结果广州市2009年-2014年生食水产品VP总体检出率为11.55%(56/485)。淡水产品VP检出率高于海产品;甲壳类高于软体动物,最低的是鱼类。第3季度VP检出率最高(18.48%),其次为第2季度,最低的是第1季度、4季度。肉菜市场VP检出率最高,为28.57%;其次为餐饮单位、超市及批发市场;零售店检出率最低。结论广州市生食水产品存在不同程度的VP污染,检出率有明显的样品种类和季节差异,应加强整个产业链综合监管,夏秋季节开展VP食品安全风险预警。
Objective To understand the pollution level of Vibrio parahaemolyticus (VP) in raw aquatic products in Guangzhou and provide the basis for the VP monitoring of raw aquatic products. Methods A total of 485 samples of raw aquatic products from different regions of China were collected in 12 districts of the city including catering outlets, wholesale markets, meat markets, supermarkets and retail outlets. Results The overall detection rate of raw seafood VP in Guangzhou from 2009 to 2014 was 11.55% (56/485). Freshwater products VP detection rate higher than seafood; crustaceans higher than molluscs, the lowest is the fish. In the third quarter, the highest detection rate of VP was (18.48%), followed by the second quarter, the lowest was the first quarter and the fourth quarter. Meat market VP highest detection rate of 28.57%; followed by catering units, supermarkets and wholesale markets; the lowest retail store detection rate. Conclusion There are different degrees of VP pollution in raw seafood in Guangzhou. The detection rate has obvious sample types and seasonal differences. Comprehensive supervision of the whole industry chain should be strengthened and early warning of VP food safety risks should be carried out in summer and autumn.
