Cover Story: Shiga toxin-producing Escherichia coli (STEC) are important foodborne pathogens that can cause enteric disease and kidney failure in humans. Biofilms contribute to the persistence of STEC in food processing environments. Several factors, including nutrient profile, temperature, physical, and chemical properties of contact surfaces and the genomics of the strain can influence biofilm formation. Identification of the conditions that promote STEC biofilm formation in food processing facilities, is key to developing disinfection and production conditions that reduce the risk of adulteration of food.
