Staphylococcus (S.) aureus is commonly found on the skin and mucous membranes of animals. Moreover, some isolates producing staphylococcal enterotoxins (SE) are also responsible for food poisoning. This study was conducted to explore the prevalence of S. aureus enterotoxin from slaughtered pigs and cattle. A total of 202 carcass swabs were collected from slaughterhouses: 102 samples were taken from slaughtered pigs and 100 were taken from cattle, respectively. Among them, 16 (7.9%) from slaughtered pigs were found to contain S. aureus, while S. aureus was not isolated from any of the slaughtered cattle samples. Additionally, six (37.5%) of the S. aureus isolates contained genes that encode staphylococcal enterotoxin type A. Therefore, it is necessary to investigate the management of food-borne pathogens based on differences in the process by which pigs and cattle are slaughtered.
