The purpose of disinfectants is to destroy the micro-organisms that cause infectious diseases and the objective for decontamination is to reduce the numbers of viable micro-organisms to a level that is not harmful to health.
CAUTION: Care should be taken when comparing the % pathogen kill offered by different disinfectants. Always check that this performance covers the micro-organisms that need to be deactivated. Click here for an example list of those destroyed by Nemesis eH20.
Decontamination is usually a combination of processes, including cleaning and disinfection, but the effectiveness of decontamination can only be determined when there is a defined objective, such as a specific reduction in viable pathogenic micro-organisms.
Logarithmic reduction is the standard used for quantifying disinfection.
A 4-log reduction in viable organisms (colony forming units – CFUs) is the same as a 99.99% pathogen kill.
