2011-2016年广西壮族自治区市售婴幼儿食品食源性致病菌监测结果分析

Analysis of monitoring results of foodborne pathogens in infant food on the market of Guangxi Zhuang Autonomous Region in 2011-2016

目的了解广西壮族自治区婴幼儿食品中食源性致病菌污染状况和趋势,为有效开展食源性疾病防控提供科学依据。方法2011-2016年从广西壮族自治区14个市采集婴幼儿食品,按照GB 4789系列标准和《2014年国家食品污染和有害因素风险监测工作手册》规定方法分别进行4种致病菌检验。结果共检测7956份样品,其中婴幼儿谷类辅助食品阳性率为6.1%(249/4084),婴幼儿配方食品阳性率为4.7%(183/3872)。不同年度监测结果显示,婴幼儿谷类辅助食品中,阪崎肠杆菌阳性率范围为2.7%~5.6%,蜡样芽胞杆菌为2.3%~8.4%(除2011和2015年),金黄色葡萄球菌为0.0%~0.4%;婴幼儿配方食品中,阪崎肠杆菌阳性率范围为0.2%~1.8%,蜡样芽胞杆菌为10.2%~12.4%(除2011和2015年),金黄色葡萄球菌为0.0%~0.3%;沙门菌检出1份,产地为内蒙古自治区。婴幼儿谷类辅助食品中,国内阳性率为6.1%(248/4077),7份国外样品检出1份阳性样品;婴幼儿配方食品中,国内阳性率为4.7%(177/3758),国外为5.3%(6/114)。结论广西壮族自治区市售婴幼儿食品中阪崎肠杆菌和蜡样芽胞杆菌污染持续存在,对婴幼儿食品安全造成威胁,应加强对国内生产企业的卫生监管。

Objective To understand the contamination status and trend of foodborne pathogens in infant food in Guangxi Zhuang Autonomous Region,and provide reference to prevent and control the foodborne disease effectively.Methods Collecting infant food from 14 cities of Guangxi Zhuang Autonomous Region in 2011-2016.Four kinds of pathogenic bacteria were tested according to the food safety standard microbiological test(GB 4789)and the national food pollution and hazardous factors risk monitoring manual(2014).Results A total of 7956 samples were detected.The positive rate of supplementary cereal food for infants and young children was 6.1%(249/4084),and that of infant formula was 4.7%(183/3872).The positive rates of Enterobacter sakazakii,Bacillus cereus(not in 2011 and 2015)and Staphylococcus aureus were 2.7%-5.6%,2.3%-8.5%and 0.0%-0.4%respectively in supplementary cereal food for infants and young children.In the infant formula,the positive rate of Enterobacter sakazakii was from 0.2%to 1.8%.Bacillus cereus was 10.2%-12.4%(not in 2011 and 2015),and Staphylococcus aureus was 0.0%-0.3%.Salmonella was detected in one sample,and the origin was Inner Mongolia Autonomous Region.The positive rate of supplementary cereal food for infants and young children was 6.1%(248/4077)in domestic products,while there was 1 positive in 7 foreign samples.In formula food,the positive rate was 4.7%(177/3758)in domestic products and 5.3%(6/114)in imported products.Conclusion The contamination of Enterobacter sakazakii and Bacillus cereus in infant food sold in Guangxi Zhuang Autonomous Region posed a threat to infants.Therefore,it was necessary to strengthen the health supervision of domestic production enterprises.
