摘要
目的:了解 2016-2022 年银川市市售食品食源性致病菌污染情况.方法:于 2016-2022 年对银川市辖区的市售食品进行随机抽检,采集1275 份样本进行11种相关致病菌的分离培养,分析食源性致病菌污染情况.结果:共采集 1275 份样品,检出致病菌样品 67 份,总检出率为 5.25%.检出率最高的是蜡样芽胞杆菌,为 11.15%(31/278);其次为铜绿假单胞菌,检出率为 8.70%(2/23).19 类食品中,有 11 类食品检出致病菌,主要为豆制品(25.00%)、粮食制品(22.22%)、食用菌及其制品(12.50%)、焙烤及油炸类食品(9.62%)以及饮用水(8.70%);流通环节和餐饮服务环节阳性率无统计学差异;散装和预包装食品食源性致病菌的阳性率无统计学差异.结论:银川市市售食品存在食源性致病菌的污染,但各类分析无统计学差异,应继续加强监测监管.
Abstract
Objective:To investigate the contamination of foodborne pathogens in commercial food in Yinchuan from 2016 to 2022.Method:From 2016 to 2022,1275 samples were collected for isolation and culture of 11 related pathogenic bacteria,and the contamination of foodborne pathogens was analyzed.Result:A total of 1275 samples were collected,and 67 pathogenic samples were detected,with a total detection rate of 5.25%.Bacillus cereus(11.15%)(31/278)had the highest detection rate,followed by Pseudomonas aeruginosa 8.70%(2/23).Among the 19 types of food,11 types of food were found to have pathogenic bacteria,mainly soy products(25.00%),grain products(22.22%),edible fungi and their products(12.50%),baked and fried foods(9.62%)and drinking water(8.70%);there was no statistical difference between the positive rate of circulation link and catering service link;there was no significant difference in the positive rate of foodborne pathogens between bulk and pre-packaged foods.Conclusion:There is contamination of foodborne pathogens in the food sold in Yinchuan city,but there is no statistical difference in various analyses,and the monitoring and supervision should be strengthened.
