(영문초록있음) Using acceptable verification methodology, test substance showing 5log (99.999%) or higher reduction in viable count against G (-) Escherichia coli ATCC 10536 and G (+) Staphylococcus aureus ATCC 6538, respectively, under test condition for 5 min±10 sec at 20± 1℃, was considered to have sanitizer capability. These two strains have a merit in that control of micro-organisms becomes easier and reproducible results can be expected, however, in order to find out how much these two strains can be actually effective on the removal or destruction of microorganisms or pathogen that causes food poisoning locally, its sterilizing and disinfectant efficacy against pathogen that causes food poisoning with a focus on independent strains that separated from standard strains and food were compared evaluated thereof. Tests were performed by dividing it into chlorines, iodines, quaternary ammonium compounds (or quats) and alcohols. The results of this test indicated that, taking standard strains, in case of Sodium hypochlorite sterilizer and disinfectant solution, it showed sterilizing and disinfectant effect of more than 5log (99.999%) under a clean condition, and of E.coli, under a state of containing valid chlorine of 50 mg/L, and of S.aureus, under 100 mg/L. However, under dirty conditions, E.coli exhibited sterilizing and disinfectant effect of 5log in time of using valid chlorine solution of more than 100 mg/L, and particularly, in case of S.aureus, it revealed sterilizing and disinfectant effect of 5log (99.999%) and more when used valid chlorine solution that exceeded 385 mg/L. In case of iodophor sterilizer or disinfectant, it showed its ability of more than 5log (99.999%) sterilization against S.aureus with iodophor concentration of over 44 mg/L under dirty conditions. Benzylammonium chloride showed difference in terms of decreasing rate of number of bacteria between clean condition and dirty condition. However, these ammonium germicides all exhibited more than 5log (99.999%) sterilization and disinfection at the 100 mg/L concentration. In case of ethanol, it showed more than 5log (99.999%) sterilization or disinfection all with 40% solution under both clean condition and dirty condition. Sterilizing efficacy of isolated strains that belong to Sodium hypochlorite showed a difference from standard strains, and under clean condition, E.coli displayed its effect at valid chlorine of 50-65 mg/L, and under dirty condition at 220-250 mg/L. So then it revealed a lower sensibility than that of standard strains. S.aureus exhibited its sterilizing effect at 100 mg/L and 385 mg/L under clean and dirty condition respectively. Benzylammonium chloride showed its sterilizing and disinfectant efficacy at 100 mg/L and 112 mg/L each under clean and dirty condition, and sterilizer or disinfectant in the line of ethanol products showed an ability of more than 5log (99.999%) sterilization at 40% under both clean and dirty condition. Iodophor displayed a similar sterilizing efficacy to the standard strains.
