A recent study has demonstrated the efficacy of antimicrobial blue light technology for the inactivation of both dried cells and biofilms of Listeria monocytogenes on surfaces found in food processing environments. 

Researchers from the University of Georgia received a grant from the U.S. Department of Agriculture’s National Institute of Food and Agriculture to study how antimicrobial blue light can be used in food processing facilities to combat pathogenic biofilms and viruses.
