Abstract

To investigate the comparative susceptibility of E. coli and S. aureus strains isolated from Korean foods to sanitizer/disinfectants, the bactericidal efficacies of sodium hypochlorite and benzalkonium chloride were assessed by quantitative suspension tests in both 'clean' and 'dirty' conditions, respectively. The sanitizers/disinfectants achieved over 5-log reduction in viable counts of all strains at the tolerance exemption concentration, except in the case of S. aureus exposure to sodium hypochlorite under dirty condition. There were no significant differences in the susceptibility of antibiotic-resistrant and antibiotic-sensitive isolated strains to the sanitizers/disinfectants (p>0.05).

유통식품에서 분리한 E. coli 및 S. aureus의 차아염소산나트륨과 염화벤잘코늄에 대한 감수성을 현탁액시험법으로 청정조건과 오염조건에서 각각 조사한 결과 차아염소산나트륨의 오염조건에서 S. aureus가 5 log 감소의 살균소독력이 나타나지 않았을 뿐, 모든 균주가 사용범위 내에서 살균소독력을 나타내었으며, 항생제 내성균과 감수성균에 대한 살균소독제 감수성의 차이는 발견되지 않았다(p>0.05).
