Disinfecting devices and related methods are provided that apply germicidal ultraviolet light to disinfect dispensing components of food and beverage dispensers. A disinfecting holster for a nozzle of a beverage dispensing handle includes a housing adapted to receive a nozzle of a beverage dispensing handle and an ultraviolet light source bent around the housing to surround at least a portion of the housing. The ultraviolet light source generates and emits germicidal ultraviolet light onto the nozzle. The housing substantially contains the ultraviolet light within the housing during the application of the ultraviolet light to the dispensing nozzle. The ultraviolet light can be periodically applied to maintain the nozzle in a disinfected state.
