Application of a 222-nm krypton-chlorine excilamp to control foodborne pathogens on sliced cheese surfaces and characterization of the bactericidal mechanisms
Conventional low-pressure UV-C germicidal lamps have potential limitations. Prospects of 222-nm KrCl excilamp as an alternative surface disinfection method for sliced cheese were evaluated. 222-nm UV-C irradiation showed significantly higher inactivation capacity for some pathogens than 254-nm radiation. The mechanisms of the enhanced lethal effect of KrCl excilamp treatment were elucidated.
