SARS-CoV-2 is primarily a respiratory pathogen that can be transmitted through fomites. Previous studies indicated that SARS-CoV-2 RNA can be detected on high-touch surfaces such as those commonly found at hospitals and food production facilities. In addition, in laboratory studies, infectious virus was found to survives for days on these surfaces. Therefore, there is a need for a validated disinfectant that can inactivate more than 3 logs of SARS-CoV-2 on common surfaces. The objective of this study was to investigate the virucidal efficacy of sodium hypochlorite (NaOCl) and peracetic acid (PAA) against SARS-CoV-2 following the ASTM standard protocol for in suspension and carrier assays. It was found that NaOCl must be used at a concentration of 1000 ppm for 10 minutes to inactivate SARS-CoV-2 on stainless steel or high density polyethylene surfaces. PAA must be used at 200 ppm for 10 minutes to inactivate SARS-CoV-2 on stainless steel and HDPE surfaces.
