2010-2012年邵阳市食源性致病菌污染状况监测分析

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。

Surveillance on the food-borne pathogens in Shaoyang, 2010-2012

Objective To monitor main food-borne pathogens in food, and identify high-risk food, and provide the fundemental data for the prevention and control of food-borne diseases. Methods In accordance with“national foodborne pathogen monitoring manual”, we collected 827 food samples from 5 monitoring points in Shaoyang city during 2010-2012. And salmonella, listeria monocytogenes, vibrio parahaemolyticus, staphylococcus aureus, campylobacter, E.coli O157：H7 and other pathogens were detected. Results We isolate 146 strains from 827 samples. The overall isolate rate was 17.65%, while the isolate rate of 2010, 2011 and 2012 year was 22.81% （65/285）, 16.44%（37/225）, 13.88% （44/317）respectively. The isolate rate of aquatic food was 53.13 %, and the isolate rate of raw poultry was 44.00 %. We investigate farmers markets, supermarkets, and restaurants, while restaurants had the top isolate rate（29.87%）.Conclusions Foodborne pathogens were common in food of Shaoyang city, and aquatic food, raw poultry were the main varieties. In three levels of consumption place, restaurants owned top isolate rate, where has higher high risk of infection.
