Antimicrobial Blue Light for Foodborne Pathogen Control


Long-term goal: The goal of this project is to investigate the application of aBL for reducing the surface viability of Listeria monocytogenes and Salmonella enterica biofilms, and of foodborne associated viruses.Specific objectives and approach:Determine optimal aBL emission doses to inactivate biofilms of L. monocytogenes and Salmonella as single species on different inert solid surfaces.Assess the impact of mixed culture biofilms on aBL inactivation effectiveness.Determine optimal conditions to inactivate norovirus surrogates, Hepatitis A virus and SARS-CoV-2.Characterize the possible interaction of aBL with sanitizers to inactivate pathogen biofilms.
