Small fruits are increasingly being implicated in outbreaks of foodborne illness, and fresh produce is now the second leading cause of foodborne illness in the U.S. Conventional methods of decontamination are not effective, and there is the need to evaluate novel technologies. Pulsed UV-light is one technology. In this study pulsed UV-light was applied to strawberries and raspberries at varying distances and times. Maximum reductions of 3.92 and 3.44 log 10 CFU/g of E. coli O157:H7 and Salmonella were obtained on raspberries and 2.14 and 2.75 log 10 CFU/g on strawberries. This research indicates that treatment with pulsed UV-light shows promise for the decontamination of small fruits.
