Study investigated cold plasma for inactivation of human norovirus surrogates. Tulane virus was significantly reduced by 1.5 PFU/g after 45s, with maximum reduction of 3.5 log PFU/g after 120s. Murine norovirus was significantly reduced by 0.5 log PFU/g after 15s, with greater than 5 log PFU/g after 90 s. Inactivation was not a result of heating. With further optimization, cold plasma may be used by food processors for nonthermal inactivation of foodborne viruses.
