2009～2010年北京市延庆县食源性致病菌污染状况

目的了解北京市延庆县食源性致病菌污染状况及污染途径,初步确定高危食品的种类,为食源性疾病的监测提供科学的依据。方法 2009～2010年抽取延庆县8类食品样品,进行沙门氏菌、单核细胞增生李斯特氏菌、金黄色葡萄球菌、肠出血性大肠埃希氏菌O157：H7、副溶血性弧菌检测。结果 250件食品样品,共检出致病菌21株（8.4%）,其中单核细胞增生李斯特氏菌11株（5.8%）,金黄色葡萄球菌5株（2.4%）,副溶血性弧菌5株（6.7%）。结论延庆县某些食品存在食源性致病菌的污染,应采取有效的控制措施,加强食品卫生监督管理,减少食源性疾患发生。

Analysis of food-borne pathogen contamination during 2009 - 2010 in Yanqing County, Beijing

Objective In order to understand the status and means of the contamination caused by food-borne pathogens in Yanqing County, Beijing, a study was conducted to determine the type of high-risk foods and provide a scientific evidence for the surveillance of food-borne disease. Methods 8 kind of food samples were selected to detect several pathogens, such as Salmonella, Listeria monocytogenes bacteria, Staphylococcus aureus, enterohemorrhagic Escherichia coli O157：H7 and Vibrio parahaemolytieus. Results There were 21 strains of pathogens （ accounting for 8.4% ） were found among 250 samples including 11 strains of Listeria monocytogenes bacteria （accounting for 5.8% ）, 5 strains of Staphylococcus aureus （accounting for 2.4% ） ,and 5 strains of Vibrio parahaemolyticus （accounting for 6. 7% ）. Conclusion According to the contamination caused by the food-borne pathogens in some foods in Yanqing County, the effective control measures should be taken to strengthen food safety supervision and management in order to reduce the risk of diseases.
