This study deals with the development of novel approach to decontaminate packaging from food pathogens by photosensitization. This study was focused in the key issue - effectiveness of the chlorophyll sodium salt-based photosensitization for decontamination of packaging from several food pathogens (Bacillus cereus, Listeria monocytogenes). Moreover, it was important to evaluate the susceptibility of pathogenic spores and biofilms to this treatment. In conclusion, obtained results reveal, that chlorophyll sodium salt-based photosensitization treatment is effective antibacterial tool against such food pathogens as Bacillus cereus and Listeria monocytogenes and can totally decontaminate packaging from these bacteria adhered on the surface of packaging. It is important to note, that chlorophyll sodium salt-based photosensitization treatment can combat resistant Listeria biofilms and Bacillus spores on the surface of packaging.
