摘　　要：目的了解北京市某区13类市售食品微生物的污染情况。方法对该区内超市、餐饮单位、农贸市场和社区商店采集的3类生鲜食品和10类直接入口食品进行微生物监测。按照国家和地方标准,判定监测结果。结果 2009—2012年监测生鲜肉类,沙门菌检出率为5.00%,金黄色葡萄球菌检出率为15.00%,单增李斯特菌检出率为1.89%,副溶血性弧菌为9.40%。直接入口食品中菌落总数检出率为45.00%,大肠菌群检出率为13.53%,金黄色葡萄球菌检出率为1.00%,单增李斯特菌检出率为0.69%,沙门菌检出率为0.14%。结论该区生鲜肉存在被致病菌污染的问题,需要加强对生鲜制品屠宰、加工、进出口等各环节的检疫。直接入口食品中菌落总数和大肠菌群污染严重,沙门菌、金黄色葡萄球菌、单增李斯特菌仍有检出,建议相关监管部门针对直接入口食品加强监管。[Objective]To understand the microbial pollution status of 13 kinds of commercially-available foods in a district of Beijing City.[Methods]Microbiological monitoring was performed on 3 kinds of raw meat and 10 kinds of ready-to-eat foods collected from supermarkets,catering units,farmers markets and community stores in this district.[Results]The monitoring results of raw meat from 2009-2012 showed the detection rate of Salmonella was 5.00%,that of staphylococcus aureus was 15.00%,1.89% of Listeria monocytogenes,9.40% of Vibrio parahaemolyticus.The detection rate of total colonies in ready-to-eat foods was 45.00%,that of Coliform was 13.53%,1.00% of Staphylococcus aureus,0.69% of Listeria monocytogenes,0.14% of Salmonella.[Conclusion]The phenomenon of fresh meat polluted by pathogenic bacteria exists in this district,therefore,it is necessary to strengthen quarantining in raw meat slaughtering and processing,import and export and so on.The coliform group and total colonies pollution is serious in ready-to-eat foods.Salmonella,staphylococcus aureus and Listeria monocytogenes can be still detected.it is suggested that the relevant supervisory department should strengthen supervision of ready-to-eat foods to reduce the occurrence of food-borne disease risk.
