摘　　要：目的了解阜阳市市售主要食品中致病菌的污染状况,为有效预防食源性疾病的发生提供科学依据。方法按国标GB4789和食源性致病菌监测手册的方法,对10类食品中的沙门氏菌、单核细胞增生李斯特氏菌、肠出血性大肠埃希菌O157:H7、阪崎肠杆菌、空肠弯曲菌、副溶血性弧菌和金黄色葡萄球菌进行分离与鉴定。结果2007～2011年859份食品样品中共检出致病菌114株,总检出率13.27%。10类食品中鲜奶的金黄色葡萄球菌污染率最高,达到52.50%(21/40),其次为水产品中的副溶血弧菌污染22.11%(21/95)。所有致病菌中金黄色葡萄球菌检出株数最多,阳性率为11.65%(53/455)。O157:H7检出株数最少,阳性率为0.26%(1/391)。农贸市场、超市、个体户三种不同监测点食源性致病菌的检出差异无统计学意义(χ2=5.15,P>0.05)。结论阜阳市主要市售食品中存在食源性致病菌的污染,其中鲜奶产品中金黄色葡萄球菌污染率最高。有针对性防范和控制各类食品致病菌的污染,是防止食源性疾病暴发的重要措施。Objective To understand the pathogen contamination in foods in Fuyang city and provide the scientific basis for effective prevention of the food-borne diseases.Methods Food samples were collected in 10 kinds of foods and examined for presence of salmonella enterica,listeria monocytogenes,enterohemorrhagic E.coli O157： H7,E.Sakazakii,campylobacter jejuni,vibrio parahaemolyticus and staphylococcus aureus according to the national standard guide.Results A total of 114（13.27%） pathogenic bacteria were isolated from the 859 specimens during the period of 2007-2011.Among them,fresh milk had the highest pollution rate of 52.50%（21/40） by staphylococcus aureus,next was animality fishery products 22.11%（21/95）by vibrio parahaemolyticus.Staphylococcus aureus had the highest positive rate of 11.65%（53/455）,O157：H7 had the lowest positive rate of 0.26%（1/391）.There was no statistical difference in detective rate among farming trade market,super-market and individual（χ2=5.15,P0.05）.Conclusions Foods might be polluted by pathogenic bacteria in Fuyang city.The pollution of staphylococcus aureus in fresh milk product was the most serious.Specific efforts towards prevention and control of food contamination are crucial to prevent food-borne illness outbreak.
