2010年广州市市售食品中食源性致病菌污染情况检测结果分析

目的:了解广州市区主要消费食品中食源性致病菌的污染状况,寻找本市引起食源性疾病的重点食品,对可能发生的食源性疾病进行预测和预报。方法:按照"全国食源性致病菌监测计划"检验技术要求提出的检测方法,采集七类食品,检测沙门菌、单核细胞增生李斯特菌、副溶血性弧菌等项目。结果:264份样品中检出致病菌64份,平均检出率为24.24%;副溶血性弧菌检出率为37.50%(24/64);单增李斯特菌检出率为5.91%(14/237);沙门菌检出率为12.12%(32/264)。结论:广州市市售食品中食源性致病菌污染较为严重,应加强细菌性食源性疾病的研究分析,做好食品安全预警预报工作。

Analysis of food-borne pathogen contamination situation in retailed food in Guangzhou in 2010

Objective:To understand the contamination status of food-borne pathogenic bacteria in main food in Guangzhou,find out the pathogen source and predict the food-borne disease.Methods:Based on the standard operation procedures in the handbook of National Surveillance on Food-borne Pathogenic Bacteria,seven kinds of food samples were collected for detection of Salmonella,Listeria monocytogenes and Vibrio parahaemolyticus.Results:264 samples were detected,64 strains of pathogens were detected with an overall positive rate of 24.24%.Vibrio parahaemolyticus had the highest positive rate of 37.50%(24 /64),Listeria monocytogenes had the positive rate of5.91%(14 /237),the positive rate of Salmonella was 12.12%(32 /264).Conclusion:The contamination status of food-borne pathogenic bacteria in main consumption of food in Guangzhou was serious.The study on risk factors of food-borne disease and the predictive warning on food safety should be enforced.
