A log kill or log-reduction is a measure of how thoroughly a decontamination process reduces the concentration of a contaminant. The term “log reduction” indicates a 10-fold reduction(one decimal), which means that with every level, the number of bacteria or virus is reduced by 90%.
What does this really mean? If there is 1 million bacteria on a surface, a disinfectant with a 2-log reduction will leave behind 10,000 bacteria while a disinfectant with a 6-log reduction will kill all but 1 cell.
1-log reduction = kills 90% of bacteria leaving 100,000 alive
2-log reduction = kills 99% of bacteria leaving 10,000 alive
3-log reduction = kills 99.9% of bacteria leaving 1,000 alive
4-log reduction = kills 99.99% of bacteria leaving 100 alive
5-log reduction = kills 99.999% of bacteria leaving 10 alive
6-log reduction = kills 99.9999% of bacteria leaving 1 cell of alive
The majority of EPA registered disinfectants have a 3 or 4-log reduction and take anywhere between 5-30 minutes to work. SteraMist is a hospital grade disinfectant that has a 6-log reduction and kills 99.9999% of bacteria and viruses within seconds of application.
