The effectiveness of ultraviolet (UV) irradiation in potentially reducing Salmonella on eggs and in egg handling facilities was evaluated using four primary parameters: test materials, UV intensity, time of UV exposure, and initial Salmonella contamination levels. Decontamination of fiber and plastic egg transfer belts, egg shells, and metal was attempted. The results showed that each of these elements varied in its capacity for sterilization by UV when contaminated with Salmonella. Regression models for system design were developed to define the relationship among UV intensity, Salmonella contamination level and time of UV exposure for each material. |
