“Blown-pack” spoilage of beef by psychrotrophic Clostridium spp. occurs sporadically and resistance of the endospores to most interventions makes them very difficult to control. Current interventions used to control spoilage and pathogenic bacteria, such as acid washes and heat treatments, do...

Application of antimicrobials for the elimination of Escherichia coli and Listeria monocytogenes in brine injected beef
DownloadFall 2013
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...

Our bodies are in a constant state of flux. Skin cells get recycled every few weeks, blood cells every few months, liver cells every two years. Over the course of a decade or so, every atom is replaced, and our bodies are made entirely new. Despite this, most of us feel that we are essentially...

Enterococcus faecalis 710C is a lactic acid bacterium that produces two bacterocins, ent7A and ent7B. Both ent7A and ent7B have strong activity against gram-positive food pathogens including Listeria spp., Clostridium spp., vancomycin-resistant enterococci (VRE) and methicillin-resistant...

Although nanocrystalline silver is used commercially to treat burns and wounds, the mechanisms of action (MOA) for its activity are not clear. The purposes of this work were to determine if nanocrystalline silver has anti-inflammatory activity, determine physicochemical properties critical for...

Climate and air quality impacts of boreal wildfires — new analytical approaches for the investigation of light absorption and atmospheric reactivity of wildfire particulate matter
DownloadSpring 2022
Wildfire smoke emissions contain substantial amounts of light-absorbing aerosols that can affect the radiation and cloud processes, resulting in climate impacts on regional and even global scales. The radiative impact of these light-absorbing aerosols is largely contributed by brown carbon (BrC),...

Public concern regarding food safety has emerged as a major policy issue. Chemicals and biotechnological processes are perceived as risks of food safety despite their contribution to an efficient, low cost agriculture and food industry. Increases in uses of biotechnological processes for foods...

Effect of Antimicrobial Exposure on Clostridioides difficile (C. difficile) Colonization of the Infant Gut Microbiota in the Canadian Healthy Infant Longitudinal Development (CHILD) Birth Cohort
DownloadSpring 2020
Introduction: Antimicrobial exposure in early life has been associated with gut microbiota dysbiosis and development of allergic diseases in childhood. In adults and older children, C. difficile is the major pathogen responsible for antibiotic-induced diarrhea but the effect of colonization with...

Effect of bacterial stress response on pathogen enumeration and its implications for food safety
DownloadSpring 2011
To determine the impact of stress response on enumeration, cell association status and the viability of Escherichia coli DH5α, Staphylococcus aureus ATCC 13565 and Listeria monocytogenes CDC 7762 were evaluated using fluorescence microscopy and were compared with the outcomes of traditional plate...

The mechanism of heat resistance in an exceptionally resistant strain of E. coli was investigated. E. coli AW1.7 was compared to a heat sensitive strain, E. coli GGG10. The heat resistance of both strains was increased by inclusion of NaCl, but only E. coli AW1.7 exhibited a consistent heat...
