2004年～2006年北京市西城区食品中主要致病菌株检测结果及分析

Analysis of main pathogens in food between 2004 and 2006 from Xicheng district in Beijing

目的：为了发现北京地区食品污染的特点,从而有针对性的制定食品卫生地方标准和控制食品污染的措施,防止病从口入,故进行了食品污染物监测网的监测工作。方法：西城区CDC作为监测点之一也在2004年～2006年的3年时间里采集了生肉类、生食蔬菜、熟肉类、水产品、冰淇淋等食品样品,进行了沙门菌、空肠弯曲菌、单增李斯特菌、金黄色葡萄球菌、O157：H7、副溶血弧菌的检验。结果：3年中共完成了430件样品的测定,共检出127株致病菌。其中检出率最高为单增李斯特菌,其次为沙门菌,其余几种致病菌检出率较低。结论：本市8种食品中都存在不同程度的污染,这也需要有关部门加强食品卫生管理,减少食源性疾病的发生。

Objective：The characteristics of food pollution in the Beijing area could be identified and summarized with the food pollutant monitoring network. Thus, the local area food safety standard and the measures to prevent and control food pollution could be constituted specifically to protect consumers from infectious diseases. Methods： As one of the monitoring agencies, Xicheng District CDC inspected the Salmonella, Campylobacter jejuni, Listeria monocytogenes, Staphylococcus aureus, O157 ： H7 and Vibrio parahemolyticus from raw meats, cooked meats, raw vegetables, seafood, and ice cream in 2004 and 2006. Results： In three years, 127 positive （pathogenic bacteria） samples were identified from total 430 samples. The frequency of Listeria monocytogenes is the highest and followed by Salmonella. Conclusion：We have found some plutions in these foods. All others have relative low frequency to the food salty and control food pollution.
