目的了解广州市食品中食源性致病菌的污染情况。方法随机抽取广州市10区2县的农场、超市、餐馆、宾馆等363种有代表性的食品样品，检测沙门氏菌、单核细胞增生李斯特菌、肠出血性大肠杆菌O 157 ∶ H7、金黄色葡萄球菌、采用国标法分离空肠弯曲菌和副溶血性弧菌。共检出致病菌72株，副溶血性弧菌检出率为33.93%，主要来源于水产品，金黄色葡萄球菌检出率为33.93%，主要来源于污染熟食，沙门氏菌检出率为1.93%，单增李斯特菌检出率为0.66%，未检出肠出血性大肠杆菌O 157 ∶ H7和空肠弯曲菌。水产食品污染率最高，生肉次之，主要是沙门氏菌。结论广州市市售食品中存在致病菌污染，水产食品和生肉是主要的致病菌污染食品，因此，应加强预防措施，控制食源性传染病。
Objective To investigate the food contamination caused by foodborne pathogens in Guangzhou.Method Three hundred and sixty-three representative kinds of food samples were collected at random from farms,supermarkets,restaurant and hotel in ten districts and two counties of Guangzhou.Salmonella,Listeria monocytogenes,EHEC O157 ∶ H7,Staphylococcus aureus,Campylobacter jejuni and Vibrio parahaemolyticus were isolated from these samples by the GB method.Result Among three hundred and sixty-three samples,seventy-two bacterial pathogens were detected.The detection rate of Vibrio parahaemolyticus,mainly from aquatic products,was 33.93%.The detection rate of Staphylococcus aureus,mainly from contaminated cooked food,was 3.00%.The detection rates of Salmonella and Listeria monocytogenes were 1.93% and 0.66%,respectively.EHEC O157 ∶ H7 and Campylobacter jejuni were not found.The contamination rates of different foods were different.Above all,the contamination rate of aquatic food was the highest while raw meat was the second,which were mainly contaminated by Salmonella.Conclusion The investigation showed that the contamination of commercial food caused by pathogens occurred in Guangzhou.The aquatic food and raw meat were the main foods that were contaminated by pathogens.Therefore,preventive measures should be strengthened to control foodborne infectious disease.
