摘　　要：目的了解甘肃省嘉峪关市即食食品中食源性致病菌的污染状况,为食源性疾病预防、控制提供科学依据。方法从选定的监测点和采样场所定期随机采样,按样品原有储存温度要求在最短时间内送达实验室,按《全国食源性致病菌监测工作手册》和GB 4789.10—2010《食品安全国家标准》规定的程序和方法检测分离致病菌。结果全年共采集1 022份样品,检出致病菌119株,总检出率为11.64%;共对7种食源性致病菌进行检测分离,其中蜡样芽孢杆菌检出率最高,为18.12%;食源性致病菌检出率学校周边小铺和小型餐馆中较高,散装食品明显高于定型包装食品,第二季度、第三季度明显高于第一季度、第四季度。结论嘉峪关市售即食食品中食源性致病菌污染较为严重,以蜡样芽孢杆菌和金黄色葡萄球菌污染为主,主要集中在米面制品、外卖配送午餐、盒饭、婴幼儿食品中。Objective To understand the contamination status of foodborne pathogenic bacteria in food in Jiayuguan,so as to provide scientific basis for the prevention and control of foodborne disease. Methods Samples,which were regularly collected from the selected monitoring points and sampling sites the under the original storage temperature of the sample,were delivered to laboratory in the shortest time,and detected and isolated for the pathogens according to the program and method of the The National Foodborne Pathogenic Bacteria Monitoring Manual and GB 4789. 10—2012 The National Food Safety Standards. Results A total of 1 022 samples were collected in the whole year,and 119 foodborne pathogens were detected with an overall detection rate of 11. 64%; 7 kinds of foodborne pathogenic bacteria were detected and isolated,and the highest detection rate was with Bacillus cereus（ 18. 12%）; the detection rate of foodborne pathogenic bacteria was more severe in the shop around schools and the small restaurant; that in the unpacked foods was significantly higher than that in the packaged food; that in the second and the third quarter was higher than that in the first and the fourth quarter. Conclusion Food in Jiayuguan are heavily contaminated by foodborne pathogens,especially Bacillus cereus and Staphylococcus aureus,which were dominant in flour products,takeaway delivery lunch,the instant rice and infant food.
