This study investigates the sensitivity of the significant foodborne pathogen <jats:italic>Listeria monocytogenes<\/jats:italic> to selected wavelengths of visible light. Results demonstrate that exposure to wavelength region 400\u2013450\u2003nm, at sufficiently high dose levels (750\u2003J\u2003cm<jats:sup>\u22122<\/jats:sup>), induced complete inactivation of a 5\u2003log<jats:sub>10<\/jats:sub> population. Exposure to wavelengths longer than 450\u2003nm did not cause significant inactivation. Analysis of 10\u2003nm bandwidths between 400 and 450\u2003nm confirmed 405(\u00b15)\u2003nm light to be most effective for the inactivation of <jats:italic>L. monocytogenes<\/jats:italic>, with a lesser bactericidal effect also evident at other wavelengths between 400 and 440\u2003nm. Identification of the optimum bactericidal wavelength enabled the comparison of inactivation using 405(\u00b15)\u2003nm filtered light and a 405\u2003nm light\u2010emitting diode (LED) array (14\u2003nm FWHM). Results demonstrate similar inactivation kinetics, indicating that the applied dose of 405\u2003nm light is the important factor. Use of the 405\u2003nm LED array for the inactivation of <jats:italic>L. monocytogenes<\/jats:italic> and other <jats:italic>Listeria<\/jats:italic> species resulted in similar kinetics, with up to 5\u2003log<jats:sub>10<\/jats:sub> reductions with a dose of 185\u2003J\u2003cm<jats:sup>\u22122<\/jats:sup>.
