摘要：

Methods of the Association of Official Analytical Chemists (AOAC) were compared with the A‐l (direct) and the A‐l (modified) methods for enumerating fecal coliforms and Escherichia coli in 702 samples, representing 11 food types. Geometric means of fecal coli‐form most probable number (MPN) values of samples analyzed by the A‐l (direct) and A‐l (modified) methods were equal to or significantly higher than the geometric means of samples analyzed by the AOAC method in 9 (82%) and 11 (100%) of the food categories, respectively. Geometric means of E. coli MPNs of samples analyzed by the A‐l (direct) and A‐l (modified) methods were equal to or significantly greater than the geometric means of samples analyzed by the AOAC method in 4 (36%) and 8 (73%) of the food categories, respectively. Overall, a significant degree of correlation was demonstrated between the AOAC method and the A‐l (modified) method in the enumeration of both fecal coliforms and E. coli in the majority of food types used in this evaluation.
