2017年楚雄地区餐饮业过桥米线微生物污染状况调查分析

目的 了解楚雄地区过桥米线微生物污染状况, 获得地域代表性数据。方法 按照《2017年云南省食品安全风险监测方案》, 采用国家标准规定的检测方法, 对60份过桥米线样品进行菌落总数、大肠菌群、霉菌计数、沙门氏菌、蜡样芽胞杆菌、变形杆菌、金黄色葡萄球菌、单核细胞增生李斯特杆菌8个微生物指标检测。结果 60份过桥米线样品中,菌落总数检出率83.33%(50/60), 大肠埃希氏菌计数检出率40.00%(24/60), 霉菌计数检出率65.00%(39/60); 致病菌总检出率33.33%(20/60), 共检出食源性致病菌23株, 检出菌株数(检出率)分别是: 蜡样芽胞杆菌9株(15.00%)、金黄色葡萄球菌6株(10.00%)、变形杆菌5株(8.33%)、沙门氏菌3株(5.00%), 单核细胞增生李斯特杆菌未检出。结论 楚雄地区过桥米线微生物污染严重, 应加强监管, 控制食用安全风险; 同时应尽快制定云南省地方特色食品过桥米线的食品质量或安全标准。

Investigation and analysis on microbial contamination of Yunnan rice noodles in catering market of Chuxiong district in 2017

Objective To understand the microbial contamination status of the Yunnan rice noodles in Chuxiong district and obtain the regional representative data. Methods According to the 2017 Yunnan food safety risk monitoring program, adopting the testing methods prescribed by national standards, the total number of bacteria, coliform bacteria, mold count, Salmonella, Staphylococcus aureus, Bacillus cereus, proteus and Listeria monocytogenes were detected in 60 samples of Yunnan rice noodles. Results Among the 60 samples of Yunnan rice noodles, the detection rate of total bacterial colonies, Escherichia coli count and mold count was 83.33% (50/60), 40.00% (24/60), and 65.00% (39/60), respectively. A total of 23 food-borne pathogenic bacteria were detected, the detection rate of pathogenic bacteria was 33.33% (20/60), and the number of detected bacterial strains (detection rate) were as follows: 9 strains of bacillus cereus (15.00%), 6 strains of staphylococcus aureus (10.00%), 5 strains of proteus (8.33%), and 3 strains of Salmonella (5.00%), and Listeria monocytogenes were not detected. Conclusions In chuxiong district, the microbial contamination of the Yunnan rice noodles is serious, we should strengthen the supervision, and control the edible safety risk. At the same time, Yunnan province local characteristics food of Yunnan rice noodles quality or safety standards should be established as soon as possible.
