目的了解平顶山市食品中食源性致病菌的污染状况及可能来源,为开展食品安全风险评估和采取针对性的控制措施提供科学依据。方法按照国家食源性致病菌监测工作手册要求的检测方法进行沙门菌、金黄色葡萄球菌、蜡样芽胞杆菌等9种致病菌的分离、鉴定。结果 740份食品中38份检出了食源性致病菌,检出率为5.14%;构成比居前三位的食源性致病菌是沙门菌(28.95%)、金黄色葡萄球菌(28.95%)、蜡样芽胞杆菌(26.32%);检出率居前的3种食品为大米盒饭(30.00%)、桶装饮用水(18.18%)、速冻水饺(15.29%)。结论平顶山市市售食品致病菌监测结果总体较好,但速冻水饺中沙门菌、大米盒饭中蜡样芽胞杆菌、桶装饮用水中铜绿假单胞菌污染较为严重,存在一定隐患,必须采取针对性的控制措施,预防和控制食源性疾病的发生。
Objective To understand the pollution status and possible sources of food-borne pathogens in food in Pingdingshan City, and to provide a scientific basis for carrying out food safety risk assessment and taking targeted control measures. Methods Nine strains of Salmonella, Staphylococcus aureus and Bacillus cereus were isolated and identified according to the detection methods required by the National Foodborne Pathogenic Virus Monitoring Manual. Results Foodborne pathogens were detected in 38 out of 740 food samples, with a detection rate of 5.14%. Among the top three foodborne pathogens, Salmonella (28.95%), Staphylococcus aureus 28.95%) and Bacillus cereus (26.32%). The top three kinds of food with the highest detection rate were rice box lunch (30.00%), bottled drinking water (18.18%) and frozen dumpling (15.29%). Conclusion The monitoring results of commercially available food pathogens in Pingdingshan City are generally good. However, the contamination of Salmonella typhi and rice cereal in Bacillus cereus and Pseudomonas aeruginosa in bottled drinking water is more serious and there are some hidden dangers and must be taken Targeted control measures to prevent and control the occurrence of foodborne diseases.
