Influence of housing system on bacterial eggshell contamination and horizontal transmission of Salmonella and Campylobacter among laying hens
(uga, 2010-12)
In the U.S. table egg industry, commercial laying hens are primarily housed in conventional battery cages. Although there are several advantages to cage management, this housing system has been extensively criticized for ...
Efficacy of a food-grade mixture of volatile compounds to reduce Salmonella levels on food contact surfaces
(uga, 2016-05)
A novel antimicrobial solution called Flavorzon was evaluated for its ability to reduce Salmonella contamination levels on food contact surfaces. The food contact surfaces evaluated include stainless steel, HDPE cutting ...
Impacts of storm-driven surface runoff and landscape characteristics on Salmonella in farm irrigation ponds in south Georgia, USA
(uga, 2014-05)
The prevalence of Salmonella in waterways of the southeastern U.S. and elsewhere raises questions about the potential role of contaminated agricultural irrigation water in foodborne illness. This thesis provides background ...
Evaluating the addition of charcoals to broiler diets on the recovery of Salmonella Typhimurium during grow-out and processing
(uga, 2014-12)
Two experiments evaluated charcoals added to the feed on the recovery of Salmonella in broilers during grow-out and processing. In both experiments, 2 "seeder" chicks were inoculated with Salmonella Typhimurium and placed ...
Food and environmental safety of pasture-raised broilers processed on-farm, in a Mobile Processing Unit and a small USDA-inspected facility
(uga, 2012-12)
The objectives of this study were to quantify the food safety risk represented by pasture-raised broilers processed on-farm, in a Mobile Processing Unit (MPU), and a small USDA-Inspected slaughter facility (U-IF) in addition ...
The RpoN regulon of Salmonella and its component RNA repair system
(uga, 2014-08)
RNA polymerase (RNAP) holoenzyme catalyzes transcription in eubacteria. The one variable subunit of this multi-subunit enzyme is σ, which mediates promoter recognition and promoter-holoenzyme interactions. In addition to ...
Hydrogen use by bacterial enteric pathogens
(uga, 2008-12)
Uptake-type hydrogenases catalyze the oxidation of molecular hydrogen in an energy-conserving manner. Many prokaryotes use these hydrogenases in their central metabolism. It has been recently shown that pathogens can use ...
Viability of Salmonella, Escherichia coli o157:h7, and Listeria monocytogenes in dairy and non-dairy yellow fat spreads and toppings
(uga, 2001-12)
Outbreaks of Salmonella, Escherichia coli O157:H7, and Listeria monocytogenes infections associated with dairy products have been documented. Seven dairy and nondairy yellow fat spreads and toppings were inoculated with ...
Evaluation of the efficacy of commercial fruit cleaners and waxes to remove or kill Escherichia coli O157:H7 and Salmonella muenchen on Red Delicious cv. apples
(uga, 2001-12)
Outbreaks of Escherichia coli O157:H7 and Salmonella infections linked to consumption of unpasteurized fruit juices have been reported. Apples spot-inoculated with E. coli O157:H7 and Salmonella Muenchen were treated with ...
Migration, PCR detection and molecular typing of Salmonella during preharvest production, postharvest storage of produce using tomato as a model
(uga, 2001-08)
Salmonellae have been increasingly identified as a cause of outbreaks of infections associated with raw produce. However, lack of information on sources of contamination before and after harvest, location of cells on or ...
