The efficacy of different sanitizers against MS2 bacteriophage introduced onto plastic or stainless steel surfaces

The virucidal activities of 11 prepared disinfectant solutions (active ingredients of household sanitizers) and 10 household sanitizers against bacteriophage MS2 on plastic and stainless steel surfaces were studied. Among the prepared sanitizers, 70–90% ethanol and ethanol-based disinfectants resulted in 1–2.5 log PFU/mL reductions on both surfaces. The 70% isopropanol and isopropanol-based formula reduced MS2 by 0.7–1.5 log PFU/mL on both surfaces. Other disinfectants, containing 0.1% benzalkonium chloride (BAC), 0.5% hydrogen peroxide, or 4% acetic acid, showed significant (P 0.05) affected by the treatment time (30–600 s). However, 85% ethanol-treated groups showed significant (P
