4. Conclusions
Using a UV-C conveyor system we were able to demonstrate a
4e6 log reduction of avirulent Y. pestis suspended in beef, chicken,
and poultry drip (purge) on stainless steel and plastic surfaces at a
dose of 0.5e1.0 J/cm2. A ca. 1 log reduction of avirulent Y. pestis was
obtained on boneless skinless chicken breasts, beef steaks, and
catfish fillets. These results are consistent with other studies indicating
that use of UV-C can significantly decontaminate exudates
on food contact surfaces, and foods, during processing.
