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。
Objective To understand the status of Salmonella contamination in common foods in Hefei and to provide evidences for the prevention and control of food borne diseases caused by this bacterium and the establishment of a salmonella contamination detection system in food. Methods Four kinds of common foods including raw meat, aquatic products, rutabaga, dairy products and fermented soybean products were collected in four districts of three counties under the jurisdiction of Hefei using sterile sampling method. Salmonella and serum were determined by means of enrichment, isolation, culture and identification Type. Results A total of 22 strains of Salmonella were detected in 442 samples, with a detection rate of 4.98%, including 14.71% of raw meat and 7.14% of aquatic products. The remaining three kinds of food were not detected. Salmonella was detected in 7 regions of raw meat samples, with a detection rate of 14.71% (15/102). Only aquatic samples were detected in Luyang District, with a detection rate of 23.33% (7/30). Serological classification belonged to 4 genotypes of B, C1, C3 and F, with 7 strains of Derbyshire, Typoson, Swine fever, Bardo, Agonist, Aberdeen, and Abortus abortuses Delpine 10 strains. Conclusions Raw meat and aquatic products are more polluted by Salmonella. Processing of these foods should be thoroughly cooked and pay attention to processing and hygiene.
