Common practice is to perform the 1:100 dilution, perform a pour plate of 1 mL in duplicate and if 2 colonies grow on each plate, the product fails specification. This common practice is scientifically unsupportable â it confused the Limit of Detection with the Limit of Quantification for the plate count method.n this analysis, plates with more than 400 CFU were unsatisfactory, as were those of less than 30 CFU, with best results in the range of 50-200 CFU/plate.
