【摘要】 [目的]了解副溶血性弧菌在泰州市市售淡水产品中的污染状况,为预警副溶血性弧菌引起的食物中毒的发生提供科学依据。[方法]不同监测季节分别从超市、农贸市场采集淡水鱼、甲壳类(虾、蟹、贝)水产品根据GB/T4789.7-2003标准进行副溶血性弧菌的分离培养和鉴定。[结果]123份淡水产品检出副溶血性弧菌的样品数为49份,总检出率为39.84%。甲壳类副溶血性弧菌检出率为55.32%,高于淡水鱼副溶血性弧菌检出率30.26%(χ2=7.61,P﹤0.05);夏季副溶血性弧菌检出率为57.81%,高于其他季节检出率。[结论]市售淡水产品中副溶血性弧菌的污染状况严重,有明显的季节特点且分离的菌株多数具有较强的毒力,是引起食物中毒的潜在危险因素。更多还原

【Abstract】 [Objective] To understand the Vibrio parahaemolyticus contamination status in fishery products of fresh water in Taizhou,so as to provide scientific basis for precaution of food-poisoning induced by Vibrio parahaemolyticus.[Methods] We collected kinds of fishery products from supermarkets and farmer’s markets such as fresh-water fishes,shellfishes,shrimp and crab in different monitoring seasons.The Vibrio parahaemolyticus were determined,separated and cultured in terms of GB /T4789.7-2003.[Results] 49 strains of Vibrio parahaemolyticus were detected in 123 fresh-water products.The total rate was 39.84%.The detectable rate of Vibrio parahaemolyticus in shellfish was 55.32%,which was higher than that in fresh water fish-es with the rate of 30.26%(χ2 = 7.61,P﹤ 0.05).The detectable rate of Vibrio parahaemolyticus in summer was 57.81%,which is higher than that in other seasons.[Conclusion] The contamination status of Vibrio parahaemolyticus in fresh water fishery products was serious.The Vibrio Parahaemolylicu strains separated had obviously strong poison and seasonal variation,which are the risk factors to produce food poisoning.更多还原
