目的了解主要食源性致病菌在食品中的污染状况,确定高危食品,为预防和控制食源性疾病提供科学依据。方法按照《全国食源性致病菌监测工作手册》检测技术要求,2010-2012年在邵阳市5个监测点共采集食品样品827份,对沙门菌、单核细胞增生李斯特菌、副溶血性弧菌、金黄色葡萄球菌、空肠弯曲菌和大肠埃希氏菌O157∶H7等10种菌的污染情况进行监测。结果 827份样品中,共检出食源性致病菌146株,总检出率为17.65%。2010-2012年不同年份致病菌样品检出率分别为22.81%(65/285)、16.44%(37/225)、13.88%(44/317)。不同种类食品中动物性水产品致病菌的检出率为53.13%,生禽肉为44.00%。对农贸市场、超市、餐饮店3种不同消费场所样品检测,其中餐饮店食源性致病菌检出率为29.87%。结论邵阳市食品食源性致病菌的污染广泛,水产品、生禽肉类是主要污染品种,3种不同消费场所以餐饮店检出率较高,在食源性疾病中存在较高感染的风险。
Objective To understand the contamination status of foodborne pathogens in foodstuffs and to identify high-risk foodstuffs and provide a scientific basis for the prevention and control of foodborne diseases. Methods A total of 827 food samples were collected from 5 monitoring points in Shaoyang City from 2010 to 2012 according to the detection technology of “National Foodborne Pathogenic Bacteria Monitoring Manual”, and the detection of Salmonella, Listeria monocytogenes, Vibrio spp., Staphylococcus aureus, Campylobacter jejuni and Escherichia coli O157: H7 and other 10 kinds of bacteria were monitored. Results Among the 827 samples, 146 food-borne pathogens were detected with a total detection rate of 17.65%. The detection rates of pathogenic bacteria in different years from 2010 to 2012 were 22.81% (65/285), 16.44% (37/225) and 13.88% (44/317), respectively. The prevalence of pathogenic bacteria of animal aquatic products in different kinds of food was 53.13% and that of raw poultry meat was 44.00%. On the farmers market, supermarkets, restaurants, three different consumer venues for testing, including food-oriented food-borne pathogenic bacteria detection rate of 29.87%. Conclusion The food-borne pathogens in Shaoyang City are widely polluted. Aquatic products and raw poultry meat are the main pollutants. The detection rate of the food and beverage outlets in the three different consumption places is high, and the prevalence of food-borne diseases is high risks of.
