Two trials were carried out by 9 and 47 laboratories to evaluate the reproducibility and sensitivity of a standard technique for the isolation of salmonellas from animal feeding stuffs. The trials involved the examinations of test samples containing known numbers of salmonellas by a buffered peptone water pre-enrichment technique. Statistical analysis of the results of the trials showed that the method was capable of detecting salmonellas in most probable numbers as low as 2.3 per 100 g and that no significant differences in performance were observed between laboratories. The standard technique described is recommended for the examination of animal feed and conforms to international recommendations.
9个和47个实验室进行了两项试验，以评估从动物饲料中分离沙门氏菌的标准技术的重现性和灵敏度。试验采用缓冲蛋白胨水预富集技术对含有已知数量沙门氏菌的测试样品进行检测。试验结果的统计分析表明，该方法能够检测出每100克低至2.3个的最可能数目的沙门氏菌，且各实验室之间在性能上未观察到显著差异。所描述的标准技术推荐用于动物饲料检测，并且符合国际建议。
