Evaluation of 405‐nm monochromatic light for inactivation of Tulane virus on blueberry surfaces IntroductionHuman norovirus (HuNoV) is recognized as the leading cause of gastroenteritis (Hal et al. ). This pathogen is transmitted mainly through the faecal–oral route, by person‐to‐person contact or contaminated food, irrigation or drinking water and from contaminated surfaces (Kingsley ). The infectious dose for HuNoV has been estimated to be between 18–1000 particles (Teunis et al. ; Atmar et al. ), making HuNoV a highly contagious virus. Fruits and vegetables that are not cooked prior to consumption are potential sources of HuNoV, (Kniel and Shearer ; Tavoschi et al. ). In vitro propagation of HuNoV is currently very challenging (Ettayebi et al. ), making assessment of viability and inactivation of HuNoV problematic.

Abstract

IntroductionHuman norovirus (HuNoV) is recognized as the leading cause of gastroenteritis (Hal et al. ). This pathogen is transmitted mainly through the faecal–oral route, by person‐to‐person contact or contaminated food, irrigation or drinking water and from contaminated surfaces (Kingsley ). The infectious dose for HuNoV has been estimated to be between 18–1000 particles (Teunis et al. ; Atmar et al. ), making HuNoV a highly contagious virus. Fruits and vegetables that are not cooked prior to consumption are potential sources of HuNoV, (Kniel and Shearer ; Tavoschi et al. ). In vitro propagation of HuNoV is currently very challenging (Ettayebi et al. ), making assessment of viability and inactivation of HuNoV problematic. Therefore, research on nonthermal inactivation methods for HuNoV often utilizes genetically related surrogates, such as murine norovirus and Tulane virus (TV; Farkas ).Visible blue 405‐nm light is one potentially promising inactivation technology. The antimicrobial effect of visible 405‐nm blue light is known to be effective against Gram‐positive and Gram‐negative bacteria, yeast, filamentous fungi, and bacterial and fungal spores (Jori ; Maclean et al. , ; Barneck et al. ; Guffey et al. ; Lacombe et al. ; Kim and Yuk ; Kim et al. ; Sommers et al. ) and is actively being researched as a method for
