Analysis of salmonella pollution in five kinds of food in Hefei

目的了解合肥地区常见食品中沙门氏菌污染状况,为预防和控制该菌引起的食源性疾病,建立食品中沙门氏菌污染检测系统提供依据。方法在合肥所辖三县四区,采用无菌采样方法,采集生肉、水产品、卤菜、乳制品和发酵豆制品五大类常见食品,通过增菌、分离培养、鉴定方法,确定沙门氏菌属和血清分型。结果 442份样品检出22株沙门氏菌,检出率4.98%,其中生肉类14.71%,水产品类7.14%,其余三类食品未检出。生肉类样品在7个地区均检出沙门氏菌,检出率为14.71%(15/102);水产类样品只有在庐阳区检出,检出率为23.33%(7/30)。血清分型分属B、C1、C3、F等4个群7个型,菌名为德尔卑、汤卜逊、猪霍乱、巴尔多、阿贡纳、阿伯丁、马流产沙门菌,其中德尔卑10株。结论生肉、水产品沙门氏菌污染较严重,加工该类食品应烧熟煮透和注意加工卫生。
