This study was conducted to survey the hygienic status of chicken meats on the microbial levels, which were collected from poultry processing plants located in the local provinces in nationwide including the JeJu island (n=15) in 1997. In particular, Salmonella spp., Campylobacter jejuni, and Listeria monocytogenes, which were regarded as one of the most important entero-pathogens relating to food borne illness from poultry, were investigated on their isolation frequency including the other pathogens related on the food-borne illness. A total of 115 processed hickens were submitted on the present study. In general, the bacterial contamination frequency showed more or less lower (10~100 cells) than those of sold on the retail and super markets and department stores because of lacking of cross-contamination incidences, depending on the total cells, Coliforms and Staphylococcal cells count. While, Salmonella species, Campylobacter jejuni, Listeria monocytogenes, and coagulase positive Staphylococcus aureus isolation frequency of chicken meats from slaughter houses were 58.3%, 37.4%, 43.5%, and 30.4%, in order. But the present microbial isolation data were a little lower levels than those of sold on the retail and super markets and famous department stores in Seoul and GyeongGi province at the same period. It seemed that the cross-contamination problems (including the human, environmental and instrumental
factors) during the marketing stage (after the last processing procedure; rinsing step) had the major roles on the ncreasing of the microbial contamination frequency on the chicken meats after the slaughter houses.
