Immune Response and Salmonella Clearance in Broiler Chickens after Fed Arginine, Vitamin E and Prebiotics
(2012-02-14)
Four experiments were conducted to evaluate effects of arginine (ARG), vitamin E (VE) and mannanoligosaccharide (MOS) on immune response and clearance of Salmonella in broiler chickens. There were 4 groups in Exp.1 (E.1) ...
Epidemiological Investigation of Risk Factors for Microbial Contamination in Produce at the Preharvest Level
(2013-11-15)
In the United States, the proportion of outbreaks of microbial foodborne illnesses associated with fresh produce has increased over the past decades. A large proportion of these outbreaks have been caused by enteric ...
Controlling Salmonella in Poultry using Bacteriophages
(2012-10-19)
Public health concerns associated with high prevalence of foodborne salmonellosis, the emergence of antibiotic-resistant organisms and the identification of poultry meat and products as one of the most common sources of ...
Challenges of Pathogen Control in Beef Cattle Production and Processing in South Texas
(2013-01-04)
This multi-phase project was designed (1) to evaluate existing post-harvest process controls and intervention strategies used to reduce Escherichia coli O157:H7, (2) to evaluate the impacts of cattle source and environmental ...
Selected genomic and phenotypic responses of Salmonella serovars to chlorine, chlorine dioxide, and cetylpyridinium chloride
(2012-07-11)
Non-typhoidal Salmonella enterica serovars continue to be the leading cause of foodborne illnesses in United States. Chlorine, chlorine related, and quaternary compounds are generally used for disinfecting carcasses and ...
Quantification of the Antimicrobial Substances Produced by Lactic Acid Bacteria used as an Intervention to Inhibit Escherichia coli O157:H7 and Salmonella in vitro and on Fresh Spinach (Spinacia oleracea)
(2012-02-14)
The metabolic activity of bacterial microorganisms may influence the growth and metabolic activities of other microbes that are present in any specific niche. Lactic acid bacteria (LAB) are antagonistic to some microbial ...
Electron Beam Irradiation for Improving Safety of Fruits and Vegetables
(2012-07-16)
Increase in consumption of fresh cut produce over the past decade has resulted in
a rise in incidents of food borne outbreaks due to pathogens. Conventional techniques of
sanitizing washes may not be effective since the ...
Evaluation of Hot Water Wash Parameters to Achieve Maximum Effectiveness in Reducing Levels of Salmonella Typhimurium, Escherichia coli O157:H7 and coliforms/Escherichia coli on Beef Carcass Surfaces
(2010-07-14)
This study measured and compared different temperatures and dwell times of hot water treatment on the reduction of Escherichia coli O157:H7 and Salmonella Typhimurium on beef carcass surfaces. Two different types of beef ...
Efficacy of Direct Fed Microbial Components Compared to Traditional Feeding Programs Against Salmonellosis and Performance of Turkey Poults
(2016-12-07)
The research evaluated in this thesis focuses on Salmonella infection in turkeys. In both experiments, poults were randomly placed into pens of four experimental treatment groups. These four treatments groups consisted of ...
Comparison of Salmonella Presence in Bovine Lymph Nodes across Feeding Stages
(2017-05-02)
Peripheral lymph nodes (LNs) located in the fatty tissues of beef carcasses have been shown to harbor Salmonella, and thus are a potential source of contamination in beef trimmings. Salmonella prevalence within LNs differs ...
