2011~2015年吉林省食品中单增李斯特菌的 监测数据分析
目的 掌握吉林省市售食品中单增李斯特菌污染情况, 为预防食源性疾病及保障食品安全工作提供科学研究数据。方法 根据GB 4789.30-2010《食品安全国家标准 食品微生物学检验 单核细胞增生李斯特氏菌检验》及《2013年国家食品污染和有害因素风险监测工作手册》进行不同地区、不同类别及不同采样地点的食品中单增李斯特菌的风险监控。结果 2011~2015年在5093件11大类食品中共检出单增李斯特菌294株, 总检出率为5.77%。9个监测地区中, 白山、长春及四平的食品污染高于其他地区。肉与肉制品、速冻米面制品和动物性水产品的阳性检出率偏高, 分别为12.43%、5.88%和5.43%。相对餐饮服务环节, 流通环节污染率更高。散装与预包装食品检出率无显著性差别。结论 吉林省各地区市售食品存在单增李斯特菌不同程度的污染, 需要对存在高污染风险食物的生产加工、运输销售及餐饮服务多个环节加强监督监管。
Objective To investigate the status of market food contaminated with Listeria monocytogenes (L.M.) in Jilin province, in order to provide scientific data for the prevention of foodborne disease and food safe.

Results A total of 5093 samples of 11 kinds of food were detected and analyzed. Among those, total 294 strains of L.M were isolated, and the total positive rate was 5.77%. The positive rates of Baishan, Changchun and Siping cities were higher than other regions. The positive rates of meat and meat products, quick-frozen rice flour products and animal aquatic products were much higher than others, which were 12.43%, 5.88% and 5.42%, respectively. Compared with catering and service industry, the pollution rate of circulation was much higher. The positive rate of bulk and pre-packaged food had no significant difference.
