本研究采用定性法和定量法,对通辽市五旗一县二区的牛肉及牛肉制品抽样进行沙门氏菌分离鉴定。结果显示,从210份食品样品中检出52份阳性样品,总阳性率为24.8%。在检测的牛肉与牛肉制品中:鲜生肉的沙门氏菌阳性检出率较高,其次为散装牛肉制品,纸袋包装制品中极低,而真空包装及灌装制品中未检出。本研究结合定性法和定量法检测沙门氏菌,更为真实地反映食品中沙门氏菌污染的情况。 In this study, qualitative and quantitative methods were used to carry out the isolation and identification of the samples of beef and beef products in two districts of Five Flags of Tongliao City. The results showed that from 210 food samples were detected in 52 positive samples, the total positive rate was 24.8%. Among the beef and beef products tested, the positive detection rate of salmonella in fresh meat was higher, followed by bulk beef products, very low in paper bag packaging products and undetectable in vacuum packaging and filling products. This study combined qualitative and quantitative detection of Salmonella, a more realistic reflection of the contamination of Salmonella in food.
