Antimicrobial applications of treatments using light pulses emitted from light emitting diodes (LED)
DownloadSpring 2022
Low water activity (aw) foods have been associated with several foodborne outbreaks and recalls. Eradication of foodborne microorganisms like Salmonella and Escherichia coli from low aw foods is challenging, as they are resistant to conventional decontamination practices. High intensity light...

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...

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...

Spring 2019
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...

Strains of Escherichia coli may survive heat or pressure stress, acquire specific virulence genes and cause severe human diseases. The locus of heat resistance (LHR) has been identified as an important heat resistant element in E. coli. The objective of this thesis was to explore the role of the...

Heat and Pressure Resistance of Escherichia coli and Its Inactivation In the Presence of Antimicrobial Compounds
DownloadFall 2014
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...

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 71°C and...

Inactivation of Escherichia coli Using Electrochemical Disinfection with Potassium Periodate (KIO4)
DownloadSpring 2020
Electrochemical disinfection of water has drawn attention in recent years as an alternative for conventional chlorine-based water treatment, due to the generation of toxic disinfection by-products (DBP) during chlorination, and increased antibiotics resistant, chlorine resistant and virulent E....

Membrane lipid homeostasis and stress resistance in Escherichia coli and Lactobacillus plantarum
DownloadSpring 2017
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...
