Detection of Shiga Toxin-Producing Escherichia coli Using Loop Mediated Isothermal Amplification
DownloadFall 2013
Shiga toxin-producing Escherichia coli (STEC) is a worldwide health concern. To detect STEC, a loop mediated isothermal amplification reaction (LAMP) was optimized to detect shiga toxin genes. LAMP’s performance was compared to conventional and real-time (RT) PCR using two product detection...

Development and validation of a surrogate strain cocktail to evaluate bactericidal effects of pressure on verotoxigenic Escherichia coli
Download2015-01-01
Garcia-Hernandez, Rigoberto, McMullen, Lynn, Gänzle, Michael G.
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...

Development of an optical biosensor based on Mach-Zehnder Interferometry for detection of Listeria monocytogenes
DownloadFall 2013
Label-free optical biosensors are widely used for the detection of pathogens due to their low-cost, real-time detection and high sensitivity. A Mach-Zehnder Interferometer (MZI) based biosensor has been developed for the detection of gram-positive bacteria, Listeria monocytogenes. An extensive...

Forty feedlot steers were fed a barley-grain-based finishing diet typical for western Canada, with two levels of supplementary vitamin E (468 or 1069 IU head-1 d-1) and the effect on backfat trans-18:1 isomeric profile was determined. Feeding 1068 IU vitamin E reduced the total trans-18:1 content...

Effect of breed type and residual feed intake on meat and collagen quality and expression of genes involved in collagen synthesis and degradation in bovine m. gluteus medius
DownloadSpring 2020
Residual feed intake (RFI) is an index of feed efficiency that has been demonstrated to be moderately heritable, with cattle having low RFI values being efficient as they consume less feed for the same weight gain. This may be of financial benefit to producers, but to be fully beneficial to...

Effect of chitosan, and bacteriocin – Producing Carnobacterium maltaromaticum on survival of Escherichia coli and Salmonella Typhimurium on beef
Download2018-01-01
Hu, Zi Yi, Balay, Danielle, Hu, Ying, McMullen, Lynn M., Gänzle, Michael G.
The aim of this study was to investigate the synergistic effect of chitosan and bacteriocins against Escherichia coli and Salmonella in media and in lean beef. The inhibitory effects of chitosan and bacteriocins against E. coli AW1.7 and S. enterica Typhimurium in media were determined by a...

Spring 2019
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...

Effect of hydrostatic pressure and antimicrobial on survival of Listeria monocytogenes and enterohaemorrhagic E.coli in beef
Download2016-01-01
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...

Effect of Preservatives on Growth and Filamentation of Listeria monocytogenes on Ready-to-Eat Meats
DownloadFall 2020
Listeria monocytogenes is a foodborne pathogen known to contaminate RTE foods and grow at refrigeration temperatures. It is also known to form filaments when stressed, which may affect enumeration and compromise consumer safety. The objective of this study was to observe the growth and...

The pressure resistance of Shiga-toxin producing Escherichia coli (STEC) depends on food matrix. This study compared the resistance of two five-strain E. coli cocktails, as well as the pressure resistant strain E. coli AW1.7, to hydrostatic pressure application in bruschetta, tzatziki, yoghurt...
