According to the regulations of the Korean Animal and Plant Quarantine Agency (QIA), offals include a greater diversity of internal organs than do those of other nations. The present study was conducted to investigate the microbiological quality of diverse edible offal products from pig and cattle slaughterhouses in Korea by performing aerobic plate counts (APCs) and E. coli counts. There were significant differences in E. coli values between red offal and white offal in both pigs and cattle. Significant differences in APCs were also observed between partial red offal and white offal of pigs (P < 0.05). However, no significant differences in APCs between red offal and white offal of cattle. The most frequently detected foodborne pathogen was Staphylococcus aureus (5.6% prevalence in pig offal and 12.5% % prevalence in cattle offal) followed by Clostridium perfringens (11.1 and 7.1%, respectively) and Salmonella (5.6% and 7.1%, respectively). None of the offal samples tested positive for E. coli O157:H7.
