2012年-2016年陕西省食品中蜡样芽胞杆菌污染情况调查

Contamination of Bacillus cereus in foods in Shaanxi Province during 2012-2016

目的了解陕西省食品中蜡样芽胞杆菌的污染情况,为制定有效的监管措施提供依据。方法按照食品安全国家标准方法,2012年-2016年在陕西省10个地市的流通、餐饮服务环节采集食品样品,进行监测分析。结果 7类3 157份食品样本中检出蜡样芽胞杆菌469株,总检出率为14.86%,各类食品中均有蜡样芽胞杆菌的检出,乳与乳制品检出率最高,为20.00%,其次是婴儿食品,为15.57%。流通和餐饮环节的检出率分别为15.06%,14.65%,差异无统计学意义(P>0.05)。2012年-2016年各年份检出率分别为15.25%、15.58%、10.45%、19.05%及14.82%,不同年份检出率差异有统计学意义(P<0.05)。商洛市、西安市、榆林市及汉中市检出率高于平均检出率。结论陕西省食品中存在蜡样芽胞杆菌污染,相关监管部门应加强重视,预防食源性疾病的发生。

Objective To study the contamination of Bacillus cereus in foods in Shaanxi Province,so as to provide basis for making effective supervision measures. Methods To took food samples for detection and analysis from the circulation and catering services in 10 cities of Shaanxi Province during 2012-2016,according to the methods from national standards for food safety. Results Among the 7 kinds of 3 157 food samples,469 strains of Bacillus cereus were detected,the total positive rate was14. 86%. Bacillus cereus were detected in all kinds of food,milk and dairy products,with the detection rate of 20%,followed by the infant food（ 15. 57%）. The detection rates of circulation and catering were 15. 06% and 14. 65% respectively,and the differences were not statistically significant（ P〈 0. 05）. The detection rates during 2012-2016 were 15. 25%,15. 58%,10. 45%,19. 05%,14. 82%,respectively,and there was statistical significance on the difference in detection rate among different years（ P〈 0. 05）. The detection rate in Shangluo,Xi＇an,Yulin,Hanzhong were higher than the average detection rate.Conclu sion There is contamination of Bacillus cereus in foods in Shaanxi,so supervision should be enhanced to prevent the foodborne diseases.
