An interlaboratory evaluation was made of the 96 h AOAC method and the 24 h A-1 procedure for the enumeration of fecal coliforms in samples of yellow corn meal, rye flour, mung beans, raw ground beef, and raw oyster homogenate. Results indicated that the efficiency of the A-1 procedure, measured in terms of recovery of fecal coliforms, and the reproducibility of that recovery were dependent on the particular food being analyzed. Accordingly, until its efficiency can be more fully demonstrated, the A-1 procedure is recommended only as a screening procedure for fecal coliforms in foods.
对96小时AOAC方法和24小时A-1程序进行了实验室间评估，以测定黄玉米粉、黑麦粉、绿豆、生牛肉末和生牡蛎匀浆样品中的粪大肠菌群数。结果表明，以粪大肠菌群回收率衡量的A-1程序的效率以及该回收率的重现性取决于所分析的特定食品。因此，在其效率能得到更充分证明之前，A-1程序仅推荐作为食品中粪大肠菌群的筛查程序。
