摘　　要：目的了解陕西省市售食品中食源性致病菌污染状况及分布和高危食品种类。方法在全国食品污染物监测网与食源性疾病监测网控制体系下，2002-2006年采集8个监测点内的7大类市售食品共计2772份，对沙门菌、单核细胞增生性李斯特菌、O157：H7出血性大肠埃希菌、弯曲菌以及副溶血性弧菌5种食源性致病菌进行监测分析。结果2772份食品样品中，分离出目标菌765株，总检出率33．67％。其中生肉类、水产品检出率最高，分别为55．31％（536／969）和43．50％（144／331），其次熟肉制品检出率17．57％（71／404）。监测的5种食源性致病菌均有检出，各类食品中单增李斯特菌和沙门菌的检出率最高，分别为16．68％和9．15％；0157：H7检出率为0．66％；水产品中副溶血性弧菌的检出率高达30．15％；生猪肉、生禽肉中弯曲菌的检出率分别达14．81％和26．07％。沙门菌经血清学鉴定，分属11个血清群或亚群、29个血清型，并发现陕西省未曾报道过的新血清群和血清型。结论通过连续5年对陕西省市售食品中食源性致病菌主动监测，掌握食源性致病菌的污染状况、高危食品及5种食源性致病菌在不同食品中的分布情况。Objective To investigate the occurrence and distributing trends of food - borne pathogens in retailed foods, find out food with high risk. Methods According to the instruction of national surveillance network on food - borne disease and food pollution, 2 772 food samples of eight kinds were collected from eight areas during a period from 2002 to 2006 to monintor and analyse the presence of Salmonella, Listeria monocytogenes, E. coli O157=H7, Campylobacter and Vibro parahaemolyticus. Results 765 strains of objective pathogens were detected with an overall positive rate 33.67 %. Raw meat and aquatic products showed a high prevalence of 55.31% （536/969） and 43.50 % （144/331） respectively, followed by cooked meat products 17.57% （71/404）. All of 5 monitored food- borne pathogens were found. On average, Listeria monocytogenes, Salmonella had the mostly high positive rate （ 16.68 % and 9.15 % respectively） than other pathogens, E. coli O157 ： H7 was 0.66 % ;While in aquatic products, Vibro parahaemolyticus reached to 30.15 %, in pork and poultry, Campylobacter was 14.81% and 26.07% respectively. Salmonella strains were serotyped into 11 serum groups or subgroups and 29 serotypes, including some new groups and types which had never been reported in Shaanxi province. Conclusion Through 5 years continuing active surveillance, the situation of contamination in daily consuming foods by food - borne pathogens had been revealed, high risk foods were found, and five food - borne pathogens＇ distributing trends in different foods were also known.
