目的分析2015年西安市市售及网售食品中食源性致病菌污染状况,为制定更加有效的食品安全监督管理措施提供科学依据。方法选择西安市6个区县及食品网店进行随机采样,采集共11类240个样本,依据食品微生物检测国家标准及国家食品污染和有害因素风险监测工作手册方法检测、鉴定致病菌。结果食品中8种致病菌总检出率为27.50%,其中以副溶血性弧菌检出率最高,为35.00%,11个食品类别中,生畜肉和生禽肉致病菌检出率分别为63.33%,70.00%;4个流通环节及5个餐饮环节中,各采样地点类型间致病菌检出率差异有统计学意义(P<0.05);6个采样区县中,沣东新城所采样品致病菌检率最高(41.94%);3个采样季度中,第4季度致病菌检出率最高(33.33%)。结论西安市市售及网售食品受致病菌污染率较高,生肉、水产、凉拌类食品受污染较严重。为改善西安市食品安全状况,控制食源性疾病爆发,相关部门应加强食品监管,采取有效的针对性措施。
Objective To analyze the status of food-borne pathogenic bacteria in the foods sold in Xi’an and net-selling in 2015, and provide a scientific basis for formulating more effective food safety supervision and management measures. Methods Six districts and counties in Xi’an were selected for random sampling and 240 samples in 11 categories were collected. Pathogenic bacteria were detected and identified according to the national standards of food microbes testing and the national risk monitoring manual for food contamination and harmful factors. Results The total detection rate of eight kinds of pathogens in food was 27.50%, of which the detection rate of Vibrio parahaemolyticus was the highest (35.00%). Among the 11 food groups, the detection rate of pathogenic bacteria of live meat and raw poultry Respectively, 63.33% and 70.00% respectively. There were significant differences in the detection rate of pathogenic bacteria among the sampling locations in four circulation links and five dining links (P <0.05) Newcastle samples collected the highest incidence of pathogenic bacteria (41.94%); three sampling quarters, the highest incidence of pathogenic bacteria in the fourth quarter (33.33%). Conclusion The prevalence of food-borne diseases in Xi’an is higher than those in other places. The pollution of raw meat, aquatic products and cold food is more serious. In order to improve food safety in Xi’an and control the outbreak of foodborne illness, relevant departments should strengthen food control and take effective targeted measures.
