Application of antimicrobials for the elimination of Escherichia coli and Listeria monocytogenes in brine injected beefDownload
The application of antimicrobials to a brine-injected raw beef roast for the elimination/inhibition of heat resistant Escherichia coli and Listeria monocytogenes was investigated. The choice of antimicrobials for use in brine injected beef was based on minimum bactericidal concentration in brine...
Heat and Pressure Resistance of Escherichia coli and Its Inactivation In the Presence of Antimicrobial CompoundsDownload
Verotoxigenic Escherichia coli (VTEC) are pathogens causing severe foodborne disease. E. coli AW1.7 is a heat resistant beef carcass isolate that may be used as a surrogate organism to study the survival of VTEC on food. This dissertation examines the heat and pressure resistance of E. coli and...
Environmental Risk Factors Associated with Contamination of Private Drinking Water Wells with Escherichia coliDownload
The focus of this research was to identify environmental risk factors that play a critical role in the contamination of drinking water wells with Escherichia coli. This study used data from a case control-study carried out between April 2005 and September 2006 in Ontario and Alberta, using...
Food processing, preservation and storage impose stresses on food bacteria. The maintenance of membrane lipid homeostasis through modification of phospholipids is a key strategy for bacteria to adapt environmental changes and survival in food. Mechanisms of adaptation are generally comparable...
Molecular Mechanisms Used by Auxiliary Regulator NlpE to Signal the Cpx Envelope Stress Response in Escherichia coliDownload
The Cpx two-component system senses and mediates adaptation to envelope stresses in Escherichia coli. NlpE is an outer membrane lipoprotein that senses surface adhesion and signals the Cpx pathway. This work focused on investigating the molecular mechanisms used by NlpE to signal the Cpx pathway...
The safety of low water activity (aW) foods is a concern due to the survival of low-infectious dose pathogens such as Escherichia coli and Salmonella. Desiccation of non-heat resistant E. coli and Salmonella increases their heat resistance; therefore, a non-thermal alternative is necessary to...
During food processing, Escherichia coli are exposed to stress from oxidation, osmolarity and temperature, and have developed mechanisms to survive. A highly heat resistant strain of E. coli AW1.7 was isolated from a beef carcass after thermal processing and it has a genomic island called the...
Escherichia coli and Salmonella are contaminants in meat products and pose a risk for foodborne illness. Thermal lethality is the traditional method for controlling pathogens in meat products. It is recommended that ground beef and poultry products be cooked to internal temperatures of 71Â°C and...
