Ultraviolet light (UV-C, 254 nm), a U.S. Food and Drug Administration
(FDA) approved food safety intervention technology, can
be used for decontamination of food and food contact surfaces. UV-C exerts its bacteriocidal effect primarily through the
formation of DNA adducts including cyclobutane pyrimidine dimers
and 6e4 photoproducts, either killing the bacteria or
rendering them unable to reproduce, and to some extent through
oxidation of proteins in the bacterial cell
