Salmonella Enteritidis forms biofilm under low temperatures on different food industry surfaces/Salmonella Enteritidis forma biofilme sob baixas temperaturas em diferentes superficies da industria de alimentos

We evaluated the influence of temperature on the ability of Salmonella Enteritidis (SE) to form biofilms on stainless steel, polyethylene, and polyurethane surfaces under different hygiene procedures. These materials were placed on SE culture and incubated at 42[+ or -]1[degrees]C, 36[+ or -]1[degrees]C, 25[+ or -]1[degrees]C, 9[+ or -]1[degrees]C, and 3[+ or -]1[degrees]C for 4, 8, 12, and 24 h. Hot water at 45[degrees]C and 85[degrees]C, 0.5% peracetic acid solution, and 1% quaternary ammonia were usedfor hygienization. Biofilm formation occurred at all temperatures evaluated, highlighting at 3[degrees]C which has not been reported as an ideal temperature for the adhesion of SE to these materials. The SE adhered more often to polyethylene surfaces than to polyurethane and stainless steel surfaces (P
