Notes:
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.
