The fluorescent filter method with “Bioplorer” (Bioplorer method), the official direct microscopic count method (Breed Method), the measurement count with “BactoScan” (BactoScan method) and the viable cell count by standard plate count method (SPC) were comparatively examined each other for the total bacterial counts (TBC) in raw milk. The coefficient of variation of Bioplorer method was better than that of Breed method. The TBC of Bioplorer method correlated well with that of Breed method. Whereas the correlations between TBC of Bioplorer method and that of BactoScan method and/or SPC were low, and the correlations between TBC of Breed method and that of BactoScan method and/or SPC were similarly low. Consequently, it was recognized that Bioplorer method was qualified for the microbes enumeration method in raw milk instead of the official direct microscopic count method (Breed method).
