中文摘要:

      目的 了解吉林省肉及肉制品食源性致病菌污染情况, 分析主要的危险因素。方法 按照随机采样原则和食源性致病菌监测样本采样要求, 对2011-2019年吉林省9个市的肉及肉制品采集5683株样品,依据GB 4789.4、GB 4789.10-2016和GB 4789.30-2016的标准方法, 对沙门氏菌、金黄色葡萄球菌、单核细胞增生李斯特氏菌进行检测。结果 共检出阳性食源性致病菌314株, 总体检出率为5.53%, 其中沙门氏菌、金黄色葡萄球菌、单核细胞增生李斯特氏菌检出率依次为1.47%、5.51%、9.41%。在不同地点采集的标本中, 农贸市场、酒店和超市检出率较高, 集体食堂和学校周围小商铺均未检出。结论 吉林省各市不同场所的肉及肉制品存在不同程度的食源性致病菌污染, 食品安全监管部门应根据污染程度实施有针对性的食品安全监督管理。

英文摘要:

      Objective To understand the contamination of foodborne pathogenic bacteria in Jilin province, analyze the main existing risk factors. Methods According to the principle of random sampling and the sample sampling requirements for foodborne pathogenic bacteria monitoring, 5683 samples were collected from meat and meat products in 9 cities of Jilin Province from 2011 to 2019. Salmonella, Staphylococcus aureus and Listeria monocytogenes were detected according to the standard method of GB/T 4789.41-2016, GB 4789.10-2016 and GB 4789.30-2016. Results Total of 314 strains of foodborne pathogens were detected, the overall detection rate was 5.53%, among which Salmonella, Staphylococcus aureus and Listeria monocytogenes were 1.47%, 5.51% and 9.41%, respectively. Among the specimens collected at different locations, the detection rate of farmers’ markets, hotels, and supermarkets was relatively high, and none were detected in collective canteens and small shops around schools Conclusion There are different degrees of foodborne pathogens contamination to meat and meat products in different places in Jilin province, and the food safety supervision department should carry out targeted food safety supervision and management according to the contamination.
