Under the experimental conditions of this study, the pathogen was found to adhere or attach readily to both stainless steel and HDPE surfaces. Controversial results on the correlation between the physicochemical properties (e.g., hydrophobicity, surface energy, surface roughness and micro-topography) of different types of food-contact surfaces and bacterial colonization have been reported (Allan et al., 2004; Mafu et al., 1990; Pasmore et al., 2002; Rodriguez et al., 2008).
