Abstract

Influenza A virus poses a major public health concern and is associated with annual epidemics and occasional pandemics. Influenza A H3N2 viruses, which are an important cause of human influenza, can infect birds and mammals. Contaminated undercooked poultry products including eggs with avian influenza virus constitute a possible risk of transmission to humans. In this study, a novel levulinic acid plus sodium dodecyl sulfate (SDS) sanitizer was evaluated for eggshell decontamination. Influenza A H3N2 virus-inoculated chicken eggshells were treated with a 5 % levulinic acid plus 2 % SDS, 2 % levulinic acid plus 1 % SDS, and 0.5 % levulinic acid plus 0.5 % SDS liquid solution for 1 min. Log reductions of viable viruses were observed by plaque assay. The 5 % levulinic acid plus 2 % SDS sanitizer provided the greatest level of influenza A H3N2 virus inactivation (2.23 log PFU), and differences in virus inactivation were observed for the various levulinic acid plus SDS concentrations tested (P ≤ 0.05). To the best of our knowledge, this is the first study demonstrating influenza A H3N2 virus inactivation on eggshells using a novel levulinic acid plus SDS sanitizer. The sanitizer may be useful for reducing egg contamination and preventing the spread of avian influenza virus to humans.
