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 10(4)cfu/cm(2) in beef and hog were 89.8% and 90.7%, respectively. 2. Escherichia coli less than l0(2)cfu/cm(2) in beef and less than l0(3)cfu/Cm(2) in hog were 98.2% and 99% 3. E coli O157: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.

It was conducted to evaluate the microbiological quality on the surface of slaughtered beef and pork products in Seoul from January 2003 to December 2003. Two hundreds four beefs and 284 pork carcasses were surveyed on generic E coli, total bacterial count for microbiological quality, and Salmonella spp as food-borne pathogen. The prevalence of the excellent or good grade(104 CFU/cm2 in SPC) of beef and pork carcasses were 99.7% and 97.9%, respectively. The frequency of beef carcasses with less than 102 CFU/cm2 of E coli was 100%, while that of pork carcasses was 98.2%. Salmonella spp was not recovered from all of beef and pork carcasses.
