2018~2019年南昌市市售生鲜肉中小肠结肠炎耶尔森氏菌污染情况分析
目的 了解2018~2019年南昌市生鲜肉品中小肠结肠炎耶尔森氏菌的污染现状。方法 以市售的生鲜肉品(猪肉、牛肉和鸡肉)为研究对象, 2018年8月～2019年7月期间每月从南昌地区当地超市和农贸市场累进行采样。样品经4 ℃冷增菌, 划线CIN平板分离后, 对可疑菌进行了生化鉴定。比较分析了不同采样场所、不同类型肉品以及不同采样时间小肠结肠炎耶尔森氏菌的检出情况。结果 采集的480份样品中小肠结肠炎耶尔森氏菌的平均检出率为14.8%, 来自超市的样品中小肠结肠炎耶尔森氏菌的检出率高于农贸市场中的样品; 猪肉、牛肉和鸡肉样品的阳性检出率分别为7.0%、18.8%和22.5%, 其中猪肉和牛肉样品中污染率最高的均为调理肉; 2018年12月～2019年4月采集的样品阳性检出率处在较高水平。结论 生鲜肉品中应重点关注整鸡、调理肉品中小肠结肠炎耶尔森氏菌污染风险, 气温较低或低温贮藏的肉品中小肠结肠炎耶尔森氏菌污染风险较高。
Objective To investigate the contamination of Yersinia enterocolitica in fresh meat in Nanchang from 2018 to 2019. Methods The main fresh meat products (pork, beef and chicken) sold in Nanchang city were selected as the research objects. From August 2018 to July 2019, samples were collected from local supermarkets and farmers' markets every month. The samples were separated by 4 ℃ cold enrichment and CIN plate, and biochemical identification of the suspected bacteria was performed. The detection rates of Y. enterocolitica in different sampling sites, different types of meat and different sampling time were compared. Results The average detection rate of Y. enterocolitica in 480 collected samples was 14.8%, and the detection rate of Y. enterocolitica in samples from supermarkets was higher than that in samples from farmers' markets. The positive detection rates of pork, beef and chicken samples were 7.0%, 18.8% and 22.5%, respectively. The highest pollution risk of pork and beef samples was from conditioned meat. The positive detection rate was at a high level from December 2018 to April 2019. Conclusion The risk of Yersinia enterocolitica contamination in whole chickens and conditioned meat should be paid more attention. The pollution risk of Y. enterocolitica was at a high level in meat stored in low temperature.
