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...

Control of Listeria monocytogenes and Heat-Resistant Escherichia coli on Vacuum-Packaged Beef
DownloadSpring 2012
Novel methods to control Listeria monocytogenes and Escherichia coli on vacuum-packaged raw beef were investigated. Bacteriocin-negative Lactobacillus sakei FUA3058 and bacteriocin-positive Carnobacterium maltaromaticum UAL307 were tested as biopreservatives, alone or in combination with...

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...

Quantification of bacteriocin gene expression in Carnobacterium maltaromaticum ATCC PTA-5313
DownloadFall 2014
Carnobacterium maltaromaticum ATCC PTA-5313, which produces bacteriocins carnocyclin A, piscicolin 126 and carnobacteriocin BM1, has been approved for use on meat products to control the growth of Listeria monocytogenes. This combination of bacteriocins is very effective as a biopreservative. It...
