陕西省市售肉与肉制食品中食源性致病菌污染监测与分析

Shaanxi commercial meat and meat Food borne pathogens in food of pollution monitoring and analysis

目的:对陕西省市售生肉类(猪、牛、禽、羊肉)与非包装熟肉制品中食源性致病菌污染状况及分布趋势监测分析,为预防食源性疾病发生、加强食品生产企业良好生产规范(GPM)和HACCP管理提供科学依据。方法:采集监测点内农贸市场、超市、餐馆等市售生肉与非包装熟肉制品,对沙门菌、单核细胞增生性李斯特菌(下称单增李斯特)、O157:H7出血性大肠杆菌(下称O157)及弯曲菌食源性致病菌进行监测。结果:从采集的1175份四类生肉样品中,分离出目标致病菌633株,最高检出率79.02%,最低检出率32.12%,平均检出率53.87%。544份非定型包装熟肉制品样品中,分离出目标致病菌86株,检出率15.81%。二者均以单增李斯特菌检出率为高,沙门菌次之。检出的237株沙门菌经血清学鉴定,分属9个血清群或亚群、32个血清型,并检出陕西省未曾报道过的新血清群或血清型。结论:通过连续7年对陕西市售生肉类与非包装熟肉制品中食源性致病菌主动监测,肉与肉制品的卫生状况堪忧,是导致食源性疾病或食物中毒的高危食品,应加强食品卫生监督检测和食品安全监管力度。

Objective：Shaanxi Province commercial raw meat（pork,beef,poultry,lamb） and non-packaged Food borne pathogens in cooked meat products and the distribution of pollution trend monitoring and analysis,for the prevention of foodborne diseases,strengthen food production and good manufacturing enterprises specification（GPM） and HACCP management provide the scientific basis.Methods： Within the Collected farmers market monitoring,supermarkets,restaurants and other commercial and non-packaged raw meat and cooked meat,Salmonella,Listeria monocytogenes of bacterium（hereinafter referred to as Listeria monocytogenes）,O157： H7 Escherichia coli（hereinafter referred to as O157） and Campylobacter monitoring of Foodborne pathogens.Results： From the collected samples in 1175 were four categories of raw meat,separating the target pathogen 633,Zuigao Jian Ratio 79.02%,the lowest detection rate of 32.12 percent,the average detection rate of 53.87%.544 copies of amorphous packing cooked meat samples,86 strains of bacteria isolated targets,the detection rate of 15.81%.Both are Listeria monocytogenes detection was high,followed by Salmonella.237 detected by serological identification of Salmonella,belonging to serogroup 9 or sub-groups,32 serotypes,and Shaanxi Province have not reported the detection of new serogroups or serotypes.Conclusion： 7 consecutive years by Shaanxi commercial raw meat and cooked meat products packaged in non-foodborne pathogens actively monitoring the health status of meat and meat products worrying is the cause of foodborne illness or food poisoning,high-risk foods,should be to strengthen food health supervision,inspection and food safety supervision.
