To evaluate the survival and removal of viruses on fresh fruit and vegetables across various temperatures and wash treatments using bacteriophage MS2 as a surrogate for human norovirus.
Measured MS2 bacteriophage survival in buffer and on inoculated fresh fruit and vegetables stored at 4 °C, 8 °C, and 22 °C for up to 50 days.
Tested viral removal efficacy from produce surfaces using potable water versus a 100 ppm chlorine wash.
MS2 viral counts decreased by <1 log10 after 50 days at 4 °C and 8 °C in buffer, while a >1 log10 reduction occurred within 9 days at 22 °C, with produce survival times exceeding shelf life.
Washing with 100 ppm chlorine achieved a mean viral reduction of 0.89 log10 across produce types (<1.5 log10 reduction in all but one case), compared to a 0.3 log10 mean reduction using potable water.
