目的了解安康市市售食品中食源性致病菌的污染状况和高危食品种类。方法依据《食品卫生微生物检验》标准和国家食源性疾病监测网要求对市售食品进行采样检测。对安康市几个主要的集贸市场和超市采集12类食品进行7种食源性致病菌检测。结果 2010年共对174份样品进行食源性致病菌污染检测,检出致病菌29株,总检出率为16.67%(29/174),其中单核细胞增生李斯特菌检出率11.11%(12/108),金黄色葡萄球菌检出率10.42%(10/96),沙门菌检出2.87%(5/174),副溶血弧菌检出率5.56%(2/36)。12类食品中熟肉制品以及速冻熟制米面制品污染率较高,分别达到了28.57%、16.67%。结论各类食品中均检出食源性致病菌,以单核细胞增生李斯特菌和金黄色葡萄球菌为主,表明这两种菌是本市目前最主要的食源性致病菌。应加强对各类食品食源性致病菌监测,并采取相应的预防和控制措施,防止食源性疾病的暴发。
Objective To understand the status of food-borne pathogens in Ankang City and the types of high-risk foods. Methods According to the standards of “Food Hygiene Microbiological Test” and the National Foodborne Disease Surveillance Network, sampling and testing were conducted on commercially available foods. A total of 12 foodstuffs were collected from several major markets and supermarkets in Ankang for foodborne pathogen detection. Results A total of 174 samples were tested for food-borne pathogens in 2010 and 29 pathogenic bacteria were detected, with a total detection rate of 16.67% (29/174). The detection rate of Listeria monocytogenes 11.11% (12/108), Staphylococcus aureus was 10.42% (10/96), Salmonella was 2.87% (5/174), and Vibrio parahaemolyticus was detected in 5.56% (2/36). The contamination rate of cooked meat products and quick-frozen cooked rice products in 12 kinds of foodstuffs were higher, reaching 28.57% and 16.67% respectively. Conclusion Food-borne pathogens were detected in all kinds of food, with Listeria monocytogenes and Staphylococcus aureus as the main ones, indicating that these two kinds of bacteria are the most important food-borne pathogens in the city. Should be strengthened on foodborne pathogens monitoring of various types of food, and take appropriate prevention and control measures to prevent the outbreak of foodborne diseases.
