Abstract

This study investigated the efficacy of common sanitizers and disinfectants on E. coli, Staphylococcus aureus, Listeria monocytogenes and Salmonella Typhimurium spiked on the surface of the main processing machine. All four microorganisms were greatly reduced by hydrogen peroxide (1,100 ppm), iodophors (25 ppm) and quarternary ammonium compounds (200 ppm). The reduction levels of E. coli, S. aureus, S. Typhimurium, and L. monocytogenes were 3.5, 3.4, 3.0, and 2.8 $log_{10}CFU/100cm^2$, respectively. Peroxy compounds and quaternary ammonium compounds can be applied to animal food manufacturing plants as a good sanitizer.

본 연구는 축산물가공공장에서의 살균소독 방법제의 효능을 평가하기 위해 주요 육가공기계 표면인 stainless steel 표면 test와 실제 축산물가공공장 적용 시험을 실시하였다 네 가지 식품위해 세균을 대상으로 simulation한 결과, E. coli, S. aureus, S. Typhimurium에 대하여는 hydrogen peroxide(1,100ppm), iodophor(25ppm) 사용 시 각각 3.5, 3.4, 3.0 log 정도의 균 감소를 보여 살균효과가 가장 컸으며, L. monocytogenes에 대해서는 quaternary ammonium compounds(200 ppm), hydrogen peroxide(1,100 ppm), iodophor(25 ppm)가 가장 좋은 약 2.8 log의 균 감소효과를 나타냈다. 대체적으로 alcohol(70%)의 효과가 가장 낮았고, hydrogen peroxide(1,100 ppm), iodophor(25 ppm)가 비슷한 수준으로 살균효과가 가장 높은 것으로 나타났다. 공장에서는 peroxy compounds와 quaternary ammonium compounds를 적용한 결과, 총균수와 대장균군수 모두 물세척에 비해 큰 균 감소효과를 볼 수 있었다.
