【摘要】：目的了解成都市动物性水产品及其外环境中部分弧菌(创伤弧菌、副溶血性弧菌、霍乱弧菌、溶藻弧菌)在养殖、销售、加工等各个环节中的分布和可能污染源,为风险评估提供可靠的基础数据。方法选择有代表性的3个养殖场、3个销售场所和3家餐饮店,分别采集鲜活/非鲜活淡水鱼/海水鱼及鲜活鱼类的水体/水底沉积物,检测创伤弧菌、副溶血性弧菌、霍乱弧菌和溶藻弧菌。结果成都市动物性水产品及其外环境中4种弧菌的总体检出率为38.8%,创伤弧菌、副溶血性弧菌、霍乱弧菌、溶藻弧菌的检出率分别为17.5%、29.1%、1.9%、5.8%;养殖场所、销售场所、餐饮环节中弧菌的检出率分别为14.7%、45.5%、55.6%;弧菌在鱼肠/鳃中的检出率(94.7%)高于在鱼肉中的检出率(32.5%),差异有统计学意义(χ2=20.01,P0.001);弧菌在非鲜活淡水鱼中的检出率(75.0%)高于鲜活淡水鱼(26.9%),差异有统计学意义(P=0.033);淡水水体和海水水体的平均盐度分别为0.19%、17.7%,平均钠含量分别为19.0 mg/L、3 138.3 mg/L;弧菌阳性样品与阴性样品在温度、平均盐度和钠含量上的差异无统计学意义(t温度=0.000,t盐度=0.585,t钠=0.540,P0.05)。结论成都市动物性水产品及外环境中弧菌的检出率较高,发生食物中毒的风险较高,需要采取一系列措施以防止食物中毒的发生。
[Abstract]:Objective to investigate the distribution and possible pollution sources of some vibrio vibrio (Vibrio vulnificus, Vibrio parahaemolyticus, Vibrio cholerae, Vibrio alginolyticus) in culture, marketing and processing of aquatic products in Chengdu. Methods three representative farms, three sales sites and three restaurants were selected to collect fresh / non-fresh freshwater fish / seawater fish and fresh fish / bottom sediments, respectively. Vibrio vulnificus, Vibrio parahaemolyticus, Vibrio cholerae and Vibrio alginolyticus were detected. The detectable rate of vibrio alginolyticus was 17.5and 29.1and 1.9and 5.8respectively. The detectable rate of Vibrio in food and beverage was 14.75.55.55.6; the detectable rate of Vibrio in fish intestine / gills was 94.77.The detection rate of Vibrio in fish was higher than that in fish meat (蠂 2 + 20.01% P 0.001), and the detection rate of Vibrio in non-fresh freshwater fish was 75.0% higher than that in fresh freshwater fish (P < 0.05), which was higher than that in fresh freshwater fish (P < 0.05). The average salinity of fresh water and seawater was 0.19 and 17.7, and the average sodium content was 19.0 mg / L, 3138.3 mg / L, respectively. There was no significant difference in average salinity and sodium content. Conclusion the detection rate of vibrio in animal aquatic products and external environment of Chengdu is higher and the risk of food poisoning is higher. A series of measures are needed to prevent food poisoning.
