For measuring general bacterial count and Escherichia coli count, the standard plate count was used to conduct a test on 113 cases of pork carcass surfaces from slaughterhouses in Incheon area from January to February 2003. And Salmonella spp, Staphylococcus aureus and Listeria monocytogenes was used to conduct a test on 68 cases of pork carcass surfaces and 76 cases of feces, that is to say, a total of 144 cases. The results were obtained as follows: In the case of general bacterial count, 29 cases(25.7%) were in the range of 100∼999 and 62 cases(54.9%) were in the range of 1,000∼9,999 and 22 cases(19.4%) were in the range of 10,000∼99,999. Meanwhile as regards E coli count, 22 cases(19.4%) were in the range of 1∼9 and 69 cases(61.2%) were in the range of 10∼99 and 22 cases(19.4%) were in the range of 100∼999. On 68 cases of pork carcass surfaces, 7 strains(10.2%) of Salmonella spp, and 12 strains(17.6%) of S aureus were detected and 27 strains(39.7%) of L monocytogenes, respectively. As for the detected Salmonella spp, 6 strains of the B group, 3 strains of S enterica subsp salame and 2 strains of S typhimurium were detected, respectively. On 76 cases of feces, 14 strains(18.4%) of Salmonella spp, and 15 strains(19.7%) of L monocytogenes and 14 strains(18.4%) of S aureus were detected respectively. As for the detected Salmonella spp, 6 strains of the B group, 4 strains of S derby and 8 strains of the C group, 5 strains of S rissen were detected, respectively. All of 42 strains of L monocytogenes were type 1. As a result of conducting a toxin test on the detected S aureus, all of 26 strains were found to be non-toxin.

Abstract
For measuring general bacterial count and Escherichia coli count, the standard plate count was used to conduct a test on 113 cases of pork carcass surfaces from slaughterhouses in Incheon area from January to February 2003. And Salmonella spp, Staphylococcus aureus and Listeria monocytogenes was used to conduct a test on 68 cases of pork carcass surfaces and 76 cases of feces, that is to say, a total of 144 cases. The results were obtained as follows: In the case of general bacterial count, 29 cases(25.7%) were in the range of 100∼999 and 62 cases(54.9%) were in the range of 1,000∼9,999 and 22 cases(19.4%) were in the range of 10,000∼99,999. Meanwhile as regards E coli count, 22 cases(19.4%) were in the range of 1∼9 and 69 cases(61.2%) were in the range of 10∼99 and 22 cases(19.4%) were in the range of 100∼999. On 68 cases of pork carcass surfaces, 7 strains(10.2%) of Salmonella spp, and 12 strains(17.6%) of S aureus were detected and 27 strains(39.7%) of L monocytogenes, respectively.
