UVC disinfection is a physical method of decontamination: UV-C light (typically 254 nm) inactivates microorganisms by disrupting their ability to reproduce. The decisive factor is the UV dose (intensity × exposure time)—once the organism-specific “lethal dose” is reached, the germ is no longer able to replicate. The required dose varies by organism: viruses, bacteria, and yeasts are generally considered highly sensitive, while some mold spores require higher doses.
Below is a selection of the most common bacteria, viruses, yeasts, and molds found in food production:
