Overview

Laboratory tests reveal that peracetic acid effectively kills various bacteria, suggesting optimal sanitizer concentrations are crucial.

Key Points

  • Peracetic acid at 1% achieved over 7 Log10 CFU reduction for all tested strains, showing superior effectiveness.
  • Sodium hypochlorite and benzalkonium chloride had limited effect on P. aeruginosa, with reductions below 2 Log10 CFU/mL.
  • Testing followed CEN guidelines, evaluating common sanitizers against Staphylococcus aureus, Salmonella, and more.
  • Results indicate that lower manufacturer-recommended concentrations may not ensure effective microbiological control.
