【摘要】：目的了解2012-2016年陕西省市售婴幼儿食品中蜡样芽胞杆菌的污染情况。方法在陕西10个地市的便利店,超市等流通环节采集婴幼儿食品,按照国家食品污染和有害因素风险监测工作手册方法进行蜡样芽胞杆菌的监测分析。结果 845份婴幼儿食品样本中检出蜡样芽胞杆菌阳性样品共132份,总检出率为15.62%,污染量在10 cfu/g~3 600 cfu/g。婴幼儿配方粉和婴幼儿即食谷类辅助食品中蜡样芽胞杆菌的检出率分别为17.18%和10.73%。计数结果100 cfu/g的样品有12份,均为婴幼儿配方粉。各年份中2015年检出率最高,为50.00%,懫自不同流通环节的样品蜡样芽胞杆菌检出率的差异有统计学意义(χ~2=11.63,P=0.017)。不同产地的样品蜡样芽胞杆菌检出率的差异有统计学意义(χ~2=41.19,P=0.008)。结论陕西省市售婴幼儿食品中存在蜡样芽胞杆菌的污染,具有一定的安全隐患,相关监管部门应予以重视加强对婴幼儿食品中蜡样芽胞杆菌的监管,预防食源性疾病的发生。
[Abstract]:Objective to investigate the contamination of Bacillus cereus in infant foods sold in Shaanxi Province from 2012 to 2016. Methods Infant foods were collected from convenience stores and supermarkets in 10 cities of Shaanxi Province. Results 132 positive samples of Bacillus cereus were detected in 845 samples of infant food. The total detection rate was 15.62%. Pollution at 10 cfu/g~3 600. The detection rates of Bacillus cereus in infant formula powder and infantile instant cereals were 17.18% and 10.73, respectively. There are 12 samples of cfu/g. In 2015, the detection rate was the highest (50.00%). The detection rate of Bacillus cereus from different circulation links was significantly different (蠂 2 + 11.63). The detection rate of Bacillus cereus was significantly different from that of samples from different areas (蠂 2: 41.19). Conclusion the contamination of Bacillus cereus in infant food on sale in Shaanxi Province has some potential safety problems. Relevant regulatory authorities should pay attention to strengthen the supervision of Bacillus cereus in infant food to prevent the occurrence of foodborne diseases.

【正文快照】： 蜡样芽胞杆菌是一种能产芽胞的革兰阳性杆菌,其分布较为广泛,存在于空气、水、土壤、植物和动物中。有报道认为食物暴露在空气中24 h以上就极易被蜡样芽胞杆菌污染[1],食用了被蜡样芽胞杆菌污染的食品易引发食物中毒[2,3],中毒症状表现为腹泻和呕吐。婴幼儿食品因富含蛋白质、
