EFFICACY OF PEROXYACETIC ACID
TIME VS. CONCENTRATIONVS. TEMPERATURE AGAINST BACTERIA, YEASTS, MOLDS, AND SPORES
These charts include 6 bacteria species, 5 yeasts, 4 molds, and 6 types of spores. The 100% Kill Times represent the time to completely eradicate (100%) of each indicated species. This chart is unusual in that it does not report the time needed to reduce the given organism to particular log reductions, which typically would be 5-6 logs.
All challenge organisms started with levels of the challenge from 107 to 108 populations.
These challenge tests would be appropriate for peroxyacetic acidformulas containing approx. 5.5% PAA and 26-27% hydrogen peroxide. Other formulas may not perform to the standards and results reported herein.
