Contamination of food by Listeria monocytogenes (L.m) frequently occurs in food processing environments,
where cells persist due to their ability to attach to surfaces. L.m is able to attach and
colonize environmental surfaces by producing a three-dimensional matrix of extracellular polymeric
substances (EPS) called biofilm; such structures are dynamic systems. Once established, biofilms can serve as a source of product contamination. Moreover, L.m in the biofilm state shows a reduced susceptibility to antimicrobial agents. The present review focuses on L.m biofilms in
food processing environments. In addition, some aspects of biofilm control and eradication are
highlighted
