目的:了解南通市市售食品中5种食源性致病菌的污染状况,对食源性疾病进行预警,为制定预防控制食源性疾病发生和流行的措施提供科学依据。方法:依据《江苏省食品污染物监测网工作方案》,参照国家标准和病原微生物检验规程对市售食品中可能存在的沙门氏菌、单核细胞增生李斯特菌、肠出血性大肠埃希氏菌O157∶H7(EHEC O157∶H7)、副溶血性弧菌和空肠弯曲菌进行检测。结果:2009～2011年共检测样品363件,检出致病菌34株,总检出率为9.37%(34/363),其中沙门氏菌的检出率为4.96%(18/363),单核细胞增生李斯特菌的检出率为2.79%(9/323),副溶血性弧菌的检出率为17.50%(7/40),EHECO157∶H7和空肠弯曲菌未检出。结论:南通市市售食品中沙门氏菌、副溶血性弧菌、单核细胞增生李斯特菌是主要污染的食源性致病菌。生禽畜肉、海水产品污染状况较严重。加强对生禽畜肉、海水产品的管理,对南通市控制食源性疾病的传播具有重要意义。
Objective: To understand the pollution status of five food-borne pathogens in Nantong food and to provide early warning to food-borne diseases and provide a scientific basis for the prevention and control of the occurrence and prevalence of food-borne diseases. Methods: Based on the Work Plan of Food Contamination Monitoring Network of Jiangsu Province, reference to national standards and pathogenic microorganism testing protocols, the possible presence of Salmonella, Listeria monocytogenes, enterohemorrhagic Escherichia coli O157 : H7 (EHEC O157: H7), Vibrio parahaemolyticus and Campylobacter jejuni. Results: A total of 363 samples were detected from 2009 to 2011, 34 of them were detected. The total detection rate was 9.37% (34/363). Among them, the detection rate of Salmonella was 4.96% (18/363) The detection rate of Listeria monocytogenes was 2.79% (9/323), the detection rate of Vibrio parahaemolyticus was 17.50% (7/40), and none of EHECO157:H7 and Campylobacter jejuni were detected. Conclusion: Salmonella, Vibrio parahaemolyticus and Listeria monocytogenes are the main food-borne pathogenic bacteria in Nantong food. Live poultry meat, seawater pollution is more serious. Strengthening the management of live poultry meat and seawater products is of great significance to the control of the spread of foodborne diseases in Nantong City.
