Efficacy of UV, Acidified Sodium Hypochlorite, and Mild Heat for Decontamination of Surface and Infiltrated Escherichia coli O157:H7 on Green Onions and Baby Spinach

Produce-associated foodborne illnesses outbreaks have highlighted the need for more effective decontamination methods to ensure the safety of fresh produce. The main objective of this study was to evaluate the individual and combined efficacies of germicidal UV light (12.5 to 500 mJ/cm(2)), acidified sodium hypochlorite (ASC 10 to 200 ppm), and mild heat (40 to 50°C) for decontaminating green onions and baby spinach infected with Escherichia...
