Technical Abstract: Bacteria can attach to surfaces and form biofilms, which have a characteristic structure consisting of microcolonies enclosed in a hydrated matrix of microbially-produced proteins and polysaccharides. In this complex biofilm network, the cells act less as individual entities and more as a collective living system, often with channels to deliver water and nutrients to the cells in the inner portion of the biofilm. Human pathogens form biofilms on food and food contact surfaces, which enhances their ability to survive harsh environments, to resist antimicrobial treatments, and to spread and persist in the food processing environment. The formation of biofilms is a food safety concern since persistent low-level contamination of foods can occur.
