江阴市2009-2011年食源性致病菌监测研究

Monitoring on food-borne pathogenic bacteria in Jiangyin city during 2009 to 2011

目的了解江阴市市售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警。方法采集8大类食品,按国标及相关方法对7种食源性致病菌进行分离、生化及血清学鉴定。结果 604份样品中检出食源性致病菌90份,平均检出率为14.90%,8类食品中,以散装熟肉制品的污染最严重,其次为凉拌菜、生禽肉类;致泻性弧菌检出率为11.09%,以副溶血性弧菌为主,占致泻性弧菌的44.64%;金黄色葡萄球菌检出率为1.71%;单增李斯特菌检出率为7.32%;变形杆菌检出率为6.07%;未检出EHECO157∶H7、沙门氏菌、志贺氏菌。结论江阴市市售食品中食源性致病菌污染较为严重,散装熟肉制品、凉拌菜、生禽肉类是主要污染食品,应加强细菌性食源性疾病相关危险因子的研究分析,做好食品安全预警工作。

Objective To learn the contamination status of food-borne pathogenic bacteria of food in Jiangyin,look for the key food which caused food origin diseases and early warning the contingent diseases.Method Collecting 8 kinds of food and 7 kinds of food-borne pathogenic bacteria were isolated from them and biochemistry and serological identification them according to national standards and correlation methods.Results Total of 90 food-borne pathogenic bacteria were detected from 604 samples and average detection rate was 14.90%.Among the 8 kinds of food,no packaging cooked products contamination were the most serious,the second were the cold food and raw meat.The detection rate of diarrhea vibrio was 11.09%,vibrio parahaemolyticus was the primarily,it accounted for 44.64%,staphylococcus aureus detection rate was 1.71%,listeria was 7.32%,bacillus proteus was 6.07%,no EHECO157∶ H7,salmonella and shigella.Conclusions The contamination status of food-borne pathogenic bacteria was serious,especially no packing cooked meat,salad,raw meat.We should enhance the study on correlated risk factors of food-borne disease and did well of the food safety early warning.
