目的了解南充市食品中食源性致病菌污染状况,为进行食品安全风险评估、制定有效的食品监管措施、预防控制食源性疾病提供科学依据。方法按照食源性致病菌定性检验方法,进行了沙门菌、单核细胞增生李斯特菌、金黄色葡萄球菌等8种致病菌的分离和鉴定,并对部分样品进行了大肠菌群、大肠埃希菌计数。结果 2014-2016年南充市共常规监测12类食品381份样品,检出致病菌59株,总检出率为15.5%;大肠菌群计数检出率26%,大肠埃希菌计数检出率31.8%。2015-2016年熟肉制品专项监测2大类259份样品,检出致病菌19株,总检出率7.3%。其中致病菌检出率居前3位的食品依次是生禽肉(85%)、桶装饮用水(16.7%)、学生餐(13.3%);食品中检出率居前3位的致病菌依次铜绿假单胞菌(16.7%)、金黄色葡萄球菌(16.6%)、单核细胞增生李斯特菌(8.6%)。结论南充市食品中存在不同程度的食源性致病菌污染,应该加强对重点食品和重点食源性致病菌的监测,采取针对性措施加强食品安全监管工作,切实有效地预防和控制食源性疾病的发生。
Objective To understand the status of food-borne pathogens in food in Nanchong City and provide scientific basis for food safety risk assessment, effective food regulatory measures and prevention and control of food-borne diseases. Methods Isolation and identification of 8 pathogenic bacteria including Salmonella, Listeria monocytogenes and Staphylococcus aureus were carried out according to the qualitative test of food-borne pathogenic bacteria. Some samples were tested for coliforms, Escherichia coli count. Results From 2014 to 2016, 381 samples of 12 kinds of food were routinely monitored in Nanchong City. 59 pathogens were detected with a total detection rate of 15.5%. The detection rate of coliform bacteria was 26%, and the count of Escherichia coli Rate of 31.8%. From 2015 to 2016, 259 samples of 2 categories of cooked meat products were specially monitored, and 19 pathogenic bacteria were detected, with a total detection rate of 7.3%. Among them, the top 3 food-borne pathogens were raw poultry meat (85%), barreled drinking water (16.7%) and student meal (13.3%), the top 3 in food Pathogenic bacteria in turn Pseudomonas aeruginosa (16.7%), Staphylococcus aureus (16.6%), Listeria monocytogenes (8.6%). Conclusion There are different levels of food-borne pathogens in food in Nanchong City, so it is necessary to strengthen the monitoring of key foodstuffs and key food-borne pathogens, take targeted measures to strengthen food safety supervision, effectively prevent and control food Origins of the disease.
