“…The superior e cacy of NEW is likely due to its mixture of chlorine species (Cl 2 , ClO-, ClO 2 ) which have higher oxidation potential than the Ca(ClO) 2 -derived hypochlorous acid (HOCl) (Rebezov et al, 2022;Vorobjeva et al, 2004;Yan et al, 2021). Other studies corroborate NEW's effectiveness against SARS-CoV-2 on fresh produce, with > 3 log reductions on strawberries and lettuce at similar chlorine concentrations (Fritz et al, 2022;Komaikul et al, 2022;Wu et al, 2022).…”

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has raised concerns over viral transmission via contaminated fresh produce. In this study, we evaluated the efficacy of Neutral Electrolyzed Water (NEW) in comparison to calcium hypochlorite (Ca(ClO)2) for the removal of SARS-CoV-2 viral RNA from vegetables stored at refrigeration temperature over a one-week period. Vegetables were inoculated with SARS-CoV-2 viral particles and subsequently treated by immersion in NEW, Ca(ClO)2, or sterile water (control) solutions. Viral RNA was extracted from the produce on days 0, 1, 3, 5, and 7 post-immersion and quantified using RT-qPCR. We demonstrate that NEW solutions reduced over 99% of detectable SARS-CoV-2 RNA on vegetables within the first 24 hours. Comparatively, Ca(ClO)2 treatment resulted in less pronounced viral RNA reduction over the 7-day experiment. At identical concentrations, NEW led to significantly higher SARS-CoV-2 RNA removal from contaminated vegetables versus Ca(ClO)2. Given the on-site production feasibility, lower environmental impacts, and reduced costs associated with NEW solutions, our findings position NEW as a promising alternative to conventional chlorine-based sanitizers for mitigation of SARS-CoV-2 presence on fresh produce.
