In this study, we isolated viable cells from various meats and determined the characteristics and taxonomic position of the Pseudomonas strains isolated. As a result, the viable cell counts ranged from 10³ to 10⁶ cfu/g. In addition, all the meat samples contained strains belonging to the genus Pseudomonas. Most of the Pseudomonas isolates grew at 4°C and decomposed lipids and proteins; they were identified as Pseudomonas fluorescens. Recently, sanitation has become well based on HACCP and etc. However, the number of cells and bacterial species consisting one part of meat samples have not changed compared with those reported 20 years ago.
