This survey was conducted to evaluate the microbiological quality and to detect of pathogenic microorganisms on the surface of slaughtered beef and pork products in two abattoirs located in Seoul from January 2001 through December 2001. Two hundred and twenty-five beef and 215 hog were surveyed for microbiological quality and 630 beef and 625 hog were detected for pathogenic microorgainsms. 1. The prevalence level on number of standard plate count(SPC) less than cfu/in beef and hog were 89.8% and 90.7%, respectively. 2. Escherichia coli less than cfu/ in beef and less than cfu/ in hog were 98.2% and 99% 3. E coli 0157:H7 was recovered from 2 beef carcasses(0.32%), and Staphylococcus aureus from 12 pork carcasses(1.90%), Listeria monocytogenes from 1 beef and 4 pork carcasses (0.15%, 0.64%) and clostridium perfringens from 14 beef and 11 pork carcasses(2.22%, 1.76%), respectively.
