摘　　要：目的监测茂名市主要食源性致病菌污染状况,为预防食源性疾病和食物中毒提供科学依据。方法在本市的大型超市、农贸市场、餐饮店和养殖场等随机采集六类食品,依据《食品卫生微生物学检验》GB/T4789-2003/2008,对采集样品分别进行沙门菌、单核细胞增生性李斯特菌、金黄色葡萄球菌、大肠杆菌O157:H7和副溶血性弧菌分离、生化及血清学鉴定。结果共监测生禽畜肉、熟肉制品、凉拌菜、豆类制品、水产品及生奶等6类样品273份,检出食源性致病菌33株,总检出率12.09%(33/273)。其中沙门菌22株,检出率8.70%(22/253);单增李斯特菌3株,检出率1.19%(3/253);副溶血弧菌5株,,检出率8.93%(5/56);金黄色葡萄球菌3株,检出率2.65%(3/113);大肠杆菌O157:H7未检出。结论茂名市食品存在食源性致病菌污染较严重,其中生禽畜肉、生奶、水产品和熟肉制品是主要受污染食品;应加强食源性致病菌的监测,防止食源性疾病和食物中毒发生。Abstract：Aim To monitor main food-borne pathogens , and provide the scientific basis for the prevention of food- borne diseases and food poisoning in Maoming City. Methods The pathogens of Salmonella,Listeria monocytogenes, Staphylococcus aureus ,Escherichia coli 0157：H7 and Vibrio parahaemolyticus were isolated,the biochemical and serotype were tested according to＂Methods of microbiology tests for food＇s hygiene＂（GB/T4789-2003[l]/2008[21） . Results There 273 food samples in 6 categories＇ including uncooked meat of livestock and poultry, cooked meat products , salad vegetables, beans products , aquatic products and raw milk were tested, 33 bacteria strains of food-borne pathogens were isolated and the total positive rate was 12.09% （33/273）. There were 22 Salmonella strains with the detection rate of 8.70% （22/253）;3 Listeria monocytogenes strains with the detection rate of 1.19% （3 / 253）; 5 Vibrio parahaemolyticus strains with the detection rate of 8.93%（5/56）; 5 Staphylococcus aureus strains with the detection rate of 2.65%（31113）; E. coli 0157：H7 was not detected. Conclusion Foods were contaminated by food-borne pathogens in MaoMing City,uncooked meat of livestock and poultry,raw milk ,aquatic products and cooked meat products were the main contaminated foods. The work of minotring of foodbome pathogens be lstrengthened to prevent the occurrence of food-borne diseases and food poisoning.
