Interaction between natural microbiota and physicochemical characteristics of lettuce surfaces can influence the attachment of Salmonella Enteritidis

► Salmonella Enteritidis adhered more in hydroponic than in conventional lettuce. ► Hydroponic lettuce showed rougher surfaces that contributed to pathogen adhesion. ► Physicochemical features of lettuce surface influenced S. Enteritidis adhesion. ► Production system and microbial contamination influenced S. Enteritidis adhesion.
