In this study, 50 rump samples of raw beef obtained from local Korean supermarkets were analyzed to surveymicrobial distributions. As results, mesophilic microorganisms ranged from (1.4±0.01)×102 to (1.6±0.05)×105 CFU/g, and totalcoliforms ranged from 0 to (1.3±0.04)×104 CFU/g. Major foodborne pathogens, including Listeria monocytogenes, Escherichiacoli O157:H7, and Salmonella spp., were not found among the samples. However, Staphylococcus aureus was isolated with 4%frequency. Other isolated microorganisms included Enterobacter amnigenus (4%), Enterobacter cloacae (24%), E. coli (24%),Listeria innocua (8%), Staphylococcus saprophyticus (56%), Staphylococcus xylosus (10%), and Staphylococcus warneri (8%).
