Penalties for Foodborne Illness: Jury Decisions and Awards in Foodborne Illness Lawsuits
… plaintiff success and payouts in jury settled foodborne illness (FBI) lawsuits. Given the risk to firms in terms of potentially large payouts, future litigation, and lost reputation, the results may provide economic incentives for food firms and others in the supply chain to produce safer and …

Application of yeast technology in ruminant nutrition
… gain (COG) (Exp. 2), and fecal prevalence of the foodborne pathogen, E. coli O157:H7 (Exp. 3). In Exp. 1, supplementing the diets of pregnant beef cows maintained on dormant winter range with DDGS improved cow performance, had limited impact on nitrogen or mineral status, and was more economical …

High resolution meltcurve PCR assay for detection of salmonella and escherichia coli O157:H7 in foods
Foodborne illnesses associated with Salmonella and Escherichia coli O157:H7 have become world-wide public-health problems. Conventional methods for the identification of foodborne pathogens are tedious, expensive, and time-consuming. Alternatively, real-time PCR (RT-PCR) as a promising method to …

Molecular characterisation of the mechanisms of compatible solute accumulation in Listeria monocytogenes
The ability of the Gram-positive foodborne pathogen Listeria monocytogenes to survive and grow in environments of elevated osmolarity can be attributed, at least in part, to the accumulation of a restricted range of low molecular mass solutes compatible with cellular function. Accumulated to high …

Ethanol Mist to Control Salmonella enterica serovar Newport on Fresh Tomato and Cantaloupe Surfaces
… fresh produce washing is a potential vehicle of foodborne pathogen contamination. This work focused on assessing the sanitizing efficacy of ethanol mist to reduce Salmonella populations on the surfaces of tomatoes and cantaloupes. Ethanol (70%) mist was applied to whole tomatoes and cantaloupe …

Airborne Campylobacter in a Poultry Processing Plant
Campylobacter is a foodborne pathogen commonly found in live poultry and raw poultry products. Identifying areas of contamination or modes of transmission during commercial processing can lead to strategies to reduce the level of Campylobacter on finished products. Monitoring levels of airborne …

Defining the tropism of Listeria monocytogenes using a comparative genomics approach
Listeria monocytogenes is a human foodborne pathogen capable of causing invasive and non-invasive infections. Ubiquitous in the environment, strains are often classified into lineages I (serovars 1/2a, 1/2c, 3a; food); II (containing serovars 1/2b, 4b, 3b; human illness); and III (4a, 4c; …

The control, survival, and growth of Listeria monocytogenes on food products
Listeria monocytogenes, a ubiquitous foodborne pathogen, was recognized over 70 years ago. It is the source of the human disease listeriosis. The majority of Listeria monocytogenes that have been isolated from food product or human cases are of the serotypes ½ a, ½ b and 4b. Due to the recent …

Oxidative stress responses in Campylobacter jejuni: the role of the Peroxide Regulator PerR
Campylobacter jejuni is a microaerophilic foodborne pathogen capable of surviving the stressful, oxygen-exposed route from an avian host and entering into the human food chain. The ability of Campylobacter to survive oxidative stress is thought to contribute to the annual ~500,000 UK cases of …

A Molecular Approach to Understanding the Effects of Original-XPC on the Modulation of the Cecal Microbiota and the Survival of Salmonella in the Poultry Host
<p>Salmonella is a foodborne pathogen commonly associated with poultry products; the economic burden to the U.S. is estimated to be approximately $693 million (without factoring in contaminated eggs). Recently, there has been pressure to withdraw sub-therapeutic levels of antibiotics (also known as …

Experimental Approaches to Understand and Control Salmonella Infection in Poultry
<p>Salmonella is a major foodborne pathogen around the world and chickens are the major reservoir to transmit Salmonella into the human food chain. For decreasing the infection of Salmonella, we developed six attenuated live vaccines based on Salmonella Enteritidis (SE) and Typhimurium (ST) for …

Using model miniature ham as a high-throughput tool to screen antimicrobials targeting l. Monocytogenes
The foodborne pathogen Listeria monocytogenes can be transmitted through eating contaminated foods, with outbreaks associated with ready-to-eat (RTE) products, such as deli ham, turkey, and hot dogs. Luncheon meats are often formulated with antimicrobial agents to limit the growth of this …

Investigating the effect of mutations in lipopolysaccharides (LPS) (O-antigen and Core region) of Salmonella Typhimurium on the colonisation of “microgreens”
In recent years, foodborne illnesses linked to the consumption of raw leafy greens, particularly microgreens, have significantly increased. Salmonella Typhimurium, a common foodborne pathogen, has been implicated in several outbreaks, underscoring the importance of understanding its interactions …

Spatial and Temporal Immune Response in House Flies in Response to Ingestion of Bacillus Cereus and Eschericha Coli 0157-H7
… many different species of bacteria that are pathogenic. Escherichia coli O157:H7 is a pathogenic enterohemorrhagic serotype of E. coli that can be vectored by the house fly. Bacillus cereus is a foodborne pathogen that has also been isolated from the house fly in previous studies. To examine …

Application of Essential Oil Compounds and Bacteriophage to Control Staphylococcus aureus
… aureus is one of the most important pathogens, causing various diseases in humans and animals. In addition, S. aureus is a common foodborne pathogen. As methicillin- resistant S. aureus (MRSA) becomes increasingly prevalent, controlling this pathogen in animals and humans with …

Factors Associated with Foodborne Pathogens and Fecal Indicator Organisms in Virginia Agricultural Soils
Prior research reveals foodborne pathogens, as well as enteric bacteria, can thrive in agricultural soils. Understanding how macro- and micronutrients, as well as meteorological factors and observational factors, impact pathogen prevalence may promote a better understanding of how pathogens persist …
