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...

Behaviour of cold-adapted Listeria monocytogenes under conditions representative of meat processing plants
DownloadSpring 2012
The objective of this study was to examine filamentation characteristics of cold-adapted Listeria monocytogenes under conditions representative of a meat processing plant. Initial analysis of 16 strains found three strains with a wide range of filamentation characteristics and these were used in...

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...

The growth of Listeria monocytogenes and spoilage microorganisms is a concern in sodium-reduced ready-to-eat (RTE) meats. To assess the microbial risk of sodium-reduced RTE meats, the microbiota of retail RTE meats was profiled and the growth of L. monocytogenes and an autochthonous microbiota...
