Salmonella spp. are responsible for foodborne illness associated with a variety of products. Many studies have documented the ability of Salmonella to adhere and form biofilms on surfaces such as plastic, cement, glass and stainless steel. The presence of these organisms in food processing environments can serve as a persistent source of contamination.
S. enterica forms biofilms that are relatively resistant to chemical sanitizing treatments. Ionizing radiation has been used to inactivate Salmonella on a variety of foods and contact surfaces, but the relative efficacy of the process against biofilm-associated cells and free-living planktonic cells is not well ...
