However, UV lamps have several limitations, including low activity at refrigeration temperatures, a long warm-up time, and risk of mercury exposure. UV-type lamps only emit light at 254 nm, so as an alternative, UV light-emitting diodes (UV-LEDs) which can produce the desired wavelengths have been developed. In this study, we validated the inactivation efficacy of UV-LEDs by wavelength and compared the results to those of conventional UV lamps. Selective media inoculated with\n            <jats:named-content content-type=\"genus-species\">Escherichia coli<\/jats:named-content>\n            O157:H7,\n            <jats:named-content content-type=\"genus-species\">Salmonella enterica<\/jats:named-content>\n            serovar Typhimurium, and\n            <jats:named-content content-type=\"genus-species\">Listeria monocytogenes<\/jats:named-content>\n            were irradiated using UV-LEDs at 266, 270, 275, and 279 nm in the UVC spectrum at 0.1, 0.2, 0.5, and 0.7 mJ\/cm\n            <jats:sup>2<\/jats:sup>\n            , respectively. The radiation intensity of the UV-LEDs was about 4 \u03bcW\/cm\n            <jats:sup>2<\/jats:sup>\n            , and UV lamps were covered with polypropylene films to adjust the light intensity similar to those of UV-LEDs. In addition, we applied UV-LED to sliced cheese at doses of 1, 2, and 3 mJ\/cm\n            <jats:sup>2<\/jats:sup>\n            . Our results showed that inactivation rates after UV-LED treatment were significantly different (\n            <jats:italic>P<\/jats:italic>\n            &lt; 0.05) from those of UV lamps at a similar intensity.
