Disinfecting effectiveness of lab-grade and household sanitizers against SARS-CoV-2 surrogate MS2 on plastic and stainless steel surfaces

Lab-grade (n=11) and household (n=10) grade disinfectants were tested for the virucidal activities against bacteriophage MS2, a surrogate of severe acute respiratory syndrome coronavirus 2, on plastic and stainless steel surfaces. The lab-grade sanitizers containing ethanol concentrations up to 90% showed 1-2.5 log PFU/ml reductions on both surfaces, and the 70% isopropanol and isopropanol-based formula also reduced MS2 by 0.7-1.5 log PFU/ml on both surfaces. Household sanitizers containing 1.84% or 3% sodium hypochlorite (NaClO) reduced 4.15-6.23 log PFU/ml MS2 on hard surfaces. The use of ethanol and NaClO-based product was a potential surface decontamination strategy in the food industry. TEAM: Lin Chen, Yoyo Lee, Yvonne Ma, Sung Sik Jang, Karen Fong, Siyun Wang
