陕西省食品中食源性致病菌监测研究

Analysis on foodborne of pathogens in Shanxi province

目的:了解陕西省食品中食源性致病菌污染状况。方法:采用现场调查与实验室分析想结合。结果:检测三地15类22种2960份食品,检出食源性致病菌916份,目标菌检出率30.95%。沙门菌、阪歧肠杆菌、副溶血性弧菌、金黄色葡萄球菌、弯曲菌、单增李斯特菌的检出率分别为10.00%、7.78%、31.12%、24.75%、24.48%、15.56%。生猪肉、生牛肉、生禽肉、生羊肉、水产品、速冻类、速冻类荤馅的致病菌检出率分别为16.50%、10.96%、20.58%、10.77%、15.92%、12.66%、24.10%。在时间上以05年最高07年最低。在空间上陕北高于关中高于陕南。结论:要严把生肉尤其是鸡、鸭、鱼肉食品的微生物污染关口,防止生肉食品变质;把握关中陕北人口密度高流动大特征的食品卫生工作;落实监管措施,促进食品安全。

Objective：To understand the Food pathogenic bacteria contamination in Shanxi Province.Methods： Combination of on-site investigation and laboratory analysis.Results： The target bacteria have been detected in 916 of 2960 samples of 15 Class and 22 varities from three districts.and t detection rate is about 30.95.%.the detection rate of Salmonella,Kosaka discrimination Enterobacter,Vibrio parahaemolyticus,Staphylococcus aureus,Campylobacter,Listeria monocytogenes were 10.00%,7.78%,31.12%,24.75%,24.48%,and 15.56% respectively,16.50%,10.96%,20.58%,10.77%,15.92%,12.66%,24.10% for pork,beef,poultry,mutton,aquatic products,frozen categories,quick-frozen stuffing respectively,higher in 2005 the lower in 2007 and step lower from the north guanzhong plain,to the southern of Shaanxi.Conclusion： We must strictly control the microbial contamination of meat to prevent the deterioration,especially for chicken,duck,fish etc.,grasp the feature of high population density and flow in northern and Guanzhong plain of Shaanxi;implementation of regulatory measures to promote food safety.
