Log reduction is a mathematical term
used to show the relative number of live microbes eliminated
from a surface by cleaning and disinfecting. Log Reduction
defines how well a disinfectant kills pathogen.For example, a 5 log-reduction, means lowering the number
of microorganisms by 100,000-fold, that is if a surface has
100,000 pathogenic microbes on it, it would be reduced to 100.1 microorganism doubles every 20 minutes, which means
in 1 hour, 1 microorganism will become 8.This means in 8 hours 1 microorganism will become 1,000,000
microorganisms. This is why it is so important to have a very high
log reduction, reducing the number of bacteria present to multiply.
