Technical Abstract: Campylobacter jejuni is a foodborne pathogen which is commonly associated with poultry, and is responsible for many foodborne illness outbreaks. Ultraviolet light (UV-C) is a U.S. Food and Drug Administration approved technology that can be used to treat foods and food contact surfaces. In this study, a multi-isolate cocktail of C. jejuni was inoculated onto poultry (chicken and turkey) skin and breast meat which were then treated with UV-C (254 nm, 0-2.0 J/cm2). UV-C did not reduce C. jejuni on poultry skin, but inactivated >1 log on skinless breast meat. UV-C (0.5 J/cm2) inactivated > 5 log of C. jejuni which was suspended in poultry exudate (drip) and then placed on stainless steel coupons. When inoculated poultry exudate was placed on food grade epoxy floor tile pieces, and then exposed to 10 uW/s/cm2 UV-C for 8 hrs to simulate decontamination of a processing environment, >6 log of the pathogen was inactivated. UV-C may be used to improve the microbiological safety of poultry and food contact surfaces by inactivating C. jejuni. .
