目的了解禹州市消费量大、流通广的食品中食源性致病菌的污染状况及分布,为食品安全风险评估和食品卫生监督提供支持。方法 2013-2015年,采集十四类食品共计304份样品,依据最新版GB,T4789的检测方法和《河南省食源性致病菌检测作业指导书》,对其进行金黄色葡萄球菌、沙门氏菌、单核细胞增生李斯特氏菌、致泻大肠埃希氏菌、志贺氏菌、阪崎杆菌、蜡样芽胞杆菌等7种食源性致病菌的监测分析。结果共检测出致病菌阳性样品50份,检出率为16.44%。其中金黄色葡萄球菌为7.17%、沙门氏菌为1.00%、单核细胞增生李斯特氏菌为3.82%、致泻大肠埃希氏菌为11.00%、蜡样芽胞杆菌为18.75%。在禹州市的食品生产经营领域,肉及肉制品、米粉类、蔬菜及其制品受致病菌污染程度较高。对三年的样品进行致病菌阳性检出率统计学分析,有明显差异。结论禹州市居民消费的主要食品中存在致病菌污染的风险。食源性致病菌的主动监测机制,在及早发现食品安全隐患、降低食源性疾病的发病率、切实保障食品消费者的身体健康方面,发挥了重要作用。
Objective To understand the pollution status and distribution of food-borne pathogens in foods with high consumption and circulation in Yuzhou, and to provide support for food safety risk assessment and food hygiene supervision. Methods From 2013 to 2015, a total of 304 samples of fourteen kinds of food were collected. Staphylococcus aureus and Salmonella were tested according to the latest GB and T4789 detection methods and the “Guide for the detection of food-borne pathogenic bacteria in Henan Province” , Listeria monocytogenes, diarrhea Escherichia coli, Shigella, Sakazakii, Bacillus cereus and other 7 kinds of foodborne pathogens monitoring analysis. Results A total of 50 positive samples were detected, the detection rate was 16.44%. Among them, Staphylococcus aureus was 7.17%, Salmonella was 1.00%, Listeria monocytogenes was 3.82%, Escherichia coli was 11.00% and Bacillus cereus was 18.75%. In the field of food production and management in Yuzhou, meat and meat products, rice noodles, vegetables and their products are highly contaminated by pathogens. Three-year samples of pathogenic bacteria positive detection rate of statistical analysis, there are significant differences. Conclusion The main food consumed by residents in Yuzhou City is at risk of pathogen contamination. The active monitoring mechanism of food-borne pathogens has played an important role in early detection of food safety hazards, reducing the incidence of food-borne diseases and effectively ensuring the health of food consumers.
