Abstract
To evaluate the microbiological quality of pork carcasses at different slaughtering process in large and small scale slaughtering houses, swabbing method was used to analyze microorganisms on the surface of pork belly in each process of before evisceration, after evisceration, before final wash, after final wash and in chilling. In autumn time, large scale slaughterhouse showed lower incidence of aerobic microorganisms (10²∼10³ CFU/㎠) than those of small scale slaughterhouse (10⁴∼10/sup 5/ CFU/㎠) during all processing lines. Samples from cold room of large scale slaughterhouse showed lower incidence of aerobic cells (10² CFU/㎠) than small scale slaughterhouse (10⁴ CFU/㎠). In winter and spring time, large scale slaughterhouse showed lower incidence of aerobic microorganisms than those of small scale slaughterhouse during the slaughtering process of before evisceration, after evisceration and before final wash, except spring samples from before final wash and chilling at cold room storage in spring time. After final wash, different sampling place of carcass such as belly, ham, jowl showed the different washing effect depending on the small and large scale slaughterhouse. After final wash, ham and belly had lower aerobic cell counts, but jowl had higher aerobic cell counts than each site before final wash.
