Abstract

The study was undertaken to provide information on the efficacy of sanitizers against bacteria with and without organic road dried on to food contact surfaces using the surface test method which EU and USA are currently implementing as one of their official test methods. Escherochia coli ATCC 10536 or Staphylococcus aureus ATCC 6538 was inoculated on to food contact surfaces, such as stainless steel, polypropylene, and silicon, which was then treated with benzalkonium chloride, sodium hypochlorite, or ethanol as a sanitizer for 5minutes at $20^{\circ}C$. Results indicated that the type of surface had little affected the efficacy of various sanitizers. In addition, 200 ppm of benzalkonium chloride or 200 ppm of sodium hypochlorite showed no definite reduction of bacterial populations in the present of organic load, while 40% ethanol showed reduction to $4\;cfu\;\log_{10}$/carrier or more in viable count in the organic load.

현재 미국 및 유럽에서 공정시험법 중 하나로 인정되고 있는 표면시험법을 사용하여 유기물과 함께 또는 유기물 없이 세균만 건조된 식품접촉 표면에서의 살균소독제 유효성에 대한 정보를 제공하고자 식품접촉표면으로 사용되는 스테인리스, 폴리프로필렌 및 실리콘에 Escherochia coli ATCC 10536 또는 Staphylococcus aureus ATCC 6538을 접종하고 살균소독제로서 염화벤잘코늄, 차아염소산나트륨 또는 에탄올을 $20^{\circ}C$에서 5분간 처리하였다. 그 결과, 각 표면의 종류는 살균소독제의 유효성에 큰 영향을 미치지 않았으며, 200 ppm 농도의 염화벤잘코늄 및 차아염소산나트륨은 유기물질이 존재할 경우 생균수를 $4\;cfu\;\log_{10}$/carrier 이상 감소시키지 못하였으나, 40% 에탄올은 생균수를 $4\;cfu\;\log_{10}$/carrier 이상 감소시키는 것으로 나타났다.
