Listeria monocytogenes (L.m.) is an agent of serious foodborne illness. It is a major concern for the food industry, since microorganism, growing in biofilms is protected against cleaning and disinfection and is difficult to eradicate. Aim of this study was to develop a protocol to assess the ability of two flexible packaging materials, named HGP40 and GND35, submitted to corona discharge treatment, to limit the production of L.m. biofilm at 12±1°C. Two strains were selected for this study: L.m ATCC 7644 and L. m. EURL 12MOB098LM isolated from dairy products. Results suggest that both L.m. strains were able to form biofilm on packaging materials tested. The differences on HGP40 and GND35s treated and not treated surfaces were not statistically significant.
