江苏省2016—2017年熟肉制品生产加工过程致病菌监测结果

目的 科学客观地了解常见熟肉制品生产过程中每个阶段致病菌分布情况、监控措施、控制效果和可能产生交叉污染的环节，发现致病菌污染的风险。方法 收集酱卤肉类、肉灌肠类、熟肉干制品类生产加工过程中环境、原辅料、中间产品、成品、终产品等同批次样品1 068份，依据食品安全国家标准方法进行沙门菌、金黄色葡萄球菌和单核细胞增生李斯特菌的检测。应用SPSS 20.0版本软件进行统计学分析，率的比较根据适用条件，分别使用χ2检验和校正χ2检验。结果 2016—2017年进入生产厂家采集环境、原辅料、中间产品、成品、终产品样品共计1 068份，检出致病菌污染样品88份，检出率8.2%（88/1 068）；其中环境样品713份，检出致病菌污染样品21份，污染率2.9%(21/713)；食品样品355份，检出致病菌污染样品67份，污染率18.9%（67/355）。结论 江苏省熟肉制品生产加工过程中存在致病菌污染，容易发生交叉污染和二次污染，应加强检测和监控。

Investigation of pathogenic bacteria polluted in cooked meat production process in Jiangsu Province from 2016 to 2017

To understand the distribution of pathogenic bacteria at each stage of the production process of commoncooked meat products, monitoring measures, control effects and possible cross -contamination links to detect the risk ofpathogenic bacteria contamination. Methods A total of 1 068 samples of environmental, raw and auxiliary materials, intermediate products, finished products and final products in the production and processing of marinated meat, meat sausage andcooked dried meat products were collected to detect Salmonella, Staphylococcus aureus and Listeria monocytogenes accordingto the national food safety standard method. SPSS version 20.0 software was used for statistical analysis, and rates were compared using chi-square test and corrected chi-square test, respectively, according to the applicable conditions. Results Among the 1 068 samples of environment, raw and auxiliary materials, intermediate products, finished products and final products in 2016-2017, 88 samples of pathogenic bacteria contamination were detected, with a detection rate of 8.2% (88/1 068).Specifically, 713 environmental samples were collected, and 21 samples of pathogenic bacteria contamination were detected,with a contamination rate of 2.9% (21/713); 355 food samples were collected, and 67 pathogenic bacteria contaminated samples, with the contamination rate of 18.9% (67/355). Conclusion Pathogenic bacteria contamination exists in the productionand processing of cooked meat products in Jiangsu Province, which is prone to cross-contamination and secondary contamination and should be strengthened for detection and monitoring
