The objective of this study was to investigate the effects on Escherichia coli O157:H7 biofilm formation of bacteria isolated from meat site surfaces following cleaning and disinfection. We first isolated and identified, to the genus level, strains of the latter organisms. Samples were obtained by swabbing the surfaces of equipment or floors over areas(More)
Seven Escherichia coli O157:H7 strains, three pathogenic (including epidemic EDL933 and Sakai) and four nonpathogenic (including mutants of EDL933 and Sakai), were compared to find a model strain to avoid the use of European third-class biological agents in biofilm studies. Comparison was performed on attached populations reached at the end of growth in(More)
Our aim was to assess the potential of Escherichia coli O157:H7 to persist in a processing environment. We studied E. coli behaviour under conditions modelling those of meat plants to establish one initial bacterial load that allows persistence and another that does not. Polyurethane coupons (3.5 cm²) were contaminated once with E. coli in meat exudate(More)
