本文作者就进口冻蛙腿采用了四种样品制备方法,即混合法、浸没法、消化法和轻洗法进行沙门氏菌的检测以比较其效率;同时研究了从蛙腿分离沙门氏菌的五种选择性琼脂平板[煌绿(BG)、亚硫酸铋(BS)、SS、木糖赖氨酸去氧胆酸盐(XLD)和Hektoen-肠遵(HE)培养基]对沙门氏菌检出率的相关性。混合法:将蛙腿样品25 g(包括肌肉、腱和骨)置于225ml乳糖肉汤中高速粉碎90秒钟后倾入灭菌烧瓶内。浸没法:将整个蛙腿直接放入装有225 ml乳糖肉汤
The authors used four sample preparation methods to import frog frog legs, that is, mixing method, immersion method, digestion method and light washing method to detect Salmonella to compare their efficiency. At the same time, the five selectivities of Salmonella isolated from frog legs Detection of Salmonella in agar plates [BG, BS, SS, XLD and Hektoen-ghosting] . Mixed method: The frog leg sample 25g (including muscle, tendon and bone) 225ml lactose broth in high speed grinding 90 seconds into the sterile flask. Immersion method: The entire frog leg into 225 ml lactose broth
