Abstract

Photodynamic therapy (PDT) and sanitation is a novel and promising technology that designed for surface cleaning and sanitation in food industry. It is based on the treatment of surfaces with nontoxic dyes (photosensitizers), followed by cleaning the surface with regular white light. The method is currently used in the medical field, food industry and was proved to have wide specificity against a variety of bacterial and viral pathogens as well as against yeasts and protozoa and development of resistance of microorganisms. Previous research highlight that the Photodynamic therapy (PDT) in medical field is a non-invasive, highly selective method for the destruction of unwanted cells and tissues. The Antimicrobial/antiviral PDT has been effectively utilized for the treatment of viral contaminations against anti-toxin, bacterial and parasitic strains
