Development and validation of a surrogate strain cocktail to evaluate bactericidal effects of pressure on verotoxigenic Escherichia coliDownload
Many strains of verotoxigenic Escherichia coli (VTEC) are highly resistant to pressure. To facilitate future studies to improve the elimination of VTEC by pressure processing of food, this study developed and validated a cocktail of non-pathogenic strains of E. coli with equal or higher...
Effect of hydrostatic pressure and antimicrobial on survival of Listeria monocytogenes and enterohaemorrhagic E.coli in beefDownload
The effects of marinades on Listeria monocytogenes and enterohaemorrhagic Escherichia coli were investigated in pressure treated beef steaks. Meat was treated with 600 MPa or 450 MPa. Marinades did not enhance pressure inactivation of E. coli in beef steaks and marinades prevented...
Escherichia coli AW1.7 is a heat resistant food isolate and the occurrence of pathogenic strains with comparable heat resistance may pose a risk to food safety. To identify the genetic determinants of heat resistance, 29 strains of E. coli that differed in their of heat resistance were analyzed...
The Spatiotemporal Occurrence and Recovery of Shiga Toxin-producing Escherichia coli (STEC) in Well-sourced Drinking Water from Southern Alberta, CanadaDownload
Shiga toxin-producing Escherichia coli (STEC) are important enteric pathogens that cause significant morbidity and mortality worldwide, as well as in Canada. Drinking water is a key exposure pathway for STEC infection and the occurrence of these pathogens in drinking water sources represents an...
