摘　　要：目的分析郑州市2016—2018年食品中主要微生物污染状况,为预防食源性疾病提供科学依据。方法按照《食品安全国家标准食品微生物学检验》方法,并参照《国家食品污染和有害因素风险监测工作手册》,对郑州市共561份食品样品进行食源性致病菌检测。结果2016—2018年郑州市共检测561份食品,检出致病菌阳性样本49份,阳性样本率为8.73%,阳性菌株51株,菌株检出率为9.09%。在检出的菌株中,蜡样芽胞杆菌最多,占总阳性菌株的41.81%,其次为沙门氏菌10株,占总阳性菌株的19.60%。在检测的10类食品中,餐饮食品阳性样本率最高,为15.83%,其次为肉与肉制品15.15%,水果及其制品10.00%,豆制品8.89%,特殊膳食用食品6.13%,调味品3.45%。从不同的采样地点分布来看,集体食堂的阳性样本率最高,其次为学校周边小商铺、街头摊点等。结论2016—2018年郑州市市售食品中存在一定的食源性致病菌污染,主要污染菌为蜡样芽胞杆菌和沙门氏菌。建议持续开展对餐饮食品、肉与肉制品和水果及其制品的致病菌监测,加强对集体食堂、学校周边小商铺、街头摊点等地点的监督管理。Objective To analyze the status of major microbial contamination in food in Zhengzhou City from 2016 to 2018,and to provide a scientific basis for prevention of food-borne diseases.Methods According to the National Food Safety Standard of Food Microbiological Examination and referring to the Manual for China National Food Contamination and Harmful Factors Risk Monitoring,a total of 561 food samples collected in Zhengzhou city were examined for pathogenic bacteria.Results A total of 561 food samples were detected in Zhengzhou city from 2016 to 2018.49 samples showed to be positive for pathogenic bacteria,with the positive sample rate of 8.73%.51 strains of food-borne pathogens were detected,and the detection rate of strains was 9.09%.Bacillus cereus was the most common pathogen among the detected strains,accounting for 41.81%of the total positive strains,followed by 10 strains of Salmonella(19.60%).Among the 10 categories of food samples,the positive sample rate of food and beverage was the highest(15.83%),followed by meat and meat products(15.15%),fruits and their products(10.00%),soybean products(8.89%),special dietary food(6.13%)and condiments(3.45%).As for the distribution of sampling sites,the positive sample rate in collective canteens was found to be the highest,followed by small shops around schools and street stalls.Conclusions Food-borne pathogen contamination was existent in food sold in markets in Zhengzhou city during 2016-2018,and the main contaminating bacteria were Bacillus cereus and Salmonella.The results suggest that continuously monitoring of food-borne pathogens in food and beverage,meat and meat products,and fruits and their products should be conducted,and supervision and management of collective canteens,small shops around schools and street stalls should be enhanced.
