Survival of Microorganisms on Covered Contaminated Stainless Steel After 2 1/2 Years

Abstract

Death rates for a 2 1/2-year period were determined for microorganisms on stainless steel strips that were initially contaminated by handling or by aerial fallout. After 2 weeks' storage, the level of contamination from handling had decreased 94%, and after 2 1/2 years most but not all of the organisms were dead. Organisms accumulated on stainless steel from aerial fallout survival longer; 40% died in 2 weeks and 93% in 2 1/2 years. The results are also discussed in relation to the 'plateau' phenomenon.
