Development of label-free detection systems targeting food-borne pathogens
Food-borne pathogens and food safety-related outbreaks have come to the forefront over recent years. Estimates on the annual cost of sicknesses, hospitalizations, and deaths run into the billions of dollars. There is a large body of research on the subject of detection of food-borne pathogens, …

Effect of spices on food borne pathogens during African milk fermentation
… and the use of natural antimicrobials for food preservation. There are no studies however on the effect of spices on foodborne pathogens in fermented milk. in this study, the antimicrobial effect of spices and essential oils when combined with milk fermentation acids and/or with each other …

Interaction of Salmonella typhimurium and Listeria monocytogenes with the murine host
Food borne pathogens that cause systemic disease must cross the intestinal barrier. Many of these pathogens, eg Salmonella typhimurium and Shigella flexneri, use M cells, found only within the follicle associated epithelium (FAE) that overlies Peyer’s patches and other lymphoid follicles, to enter …

Feed Supplementation with Natural Extracts of Cranberry and its Efficacy on Campylobacter Colonization in Poultry
… as one of the leading causative agents of food borne diarrheal illness. Epidemiological evidence has shown that poultry is the main source for human infection. Poultry are asymptomatic carriers of Campylobacter within their gastrointestinal tract, with colonization levels reaching 106-108 …

MOL-PCR For SNP Based Detection and Characterization of STEC non-O157 Strains
… Escherichia coli (STEC) strains are important food-borne pathogens that have been linked to human illness. In the United States, STEC O157:H7 strains have been attributed to the majority of disease and outbreaks; however, the frequency of disease associated with STEC non-O157 strains have also …

Diversity and virulence of the genus Cronobacter revealed by multilocus sequence typing (MLST) and comparative genomic analysis
… bacterial genus consisting of opportunistic food-borne pathogens affecting all age groups, with particularly severe clinical complications such as meningitis and necrotising enterocolitis in neonates and infants. In this study, a multilocus sequence typing (MLST) approach has been established …

Microbial Safety, Shelf Life Stability, Quality Preservation, and Consumer Acceptance of Vacuum-infused, Irradiated Chicken Breast Meat Treated with Natural Plant Extracts and Organic Acids
<p>Contamination of poultry products with food borne pathogens is a consistently recurring problem in the United States and the world. Recalls associated with chicken contamination are responsible for considerable economic losses to the poultry industry. Many decontamination steps are currently in …

The Elimination of Listeria monocytogenes Biofilms from Stainless Steel Deli Meat Slicer Components by the use of Hurdle Technologies
… is of the greatest concern amongst ready-to-eat foods. The United States Department of Agriculture's Food Safety and Inspection Services determined that deli luncheon meats pose the greatest risk of contamination from L. monocytogenes Industrial meat slicers have many removable parts that are …

Effect of Evaporative Cooling, Fat Content and Food Type on Pathogen Survival during Microwave Cooking
… microwave heating, the microbiological safety of foods prepared in the microwave has been in question for several years. Because foods are heated from the inside out and are strictly governed by their own internal properties such as ionic content, moisture level and specific heat, work must be …

Fate and Effect of Peracetic Acid Solutions on Biological Wastewater Treatment Systems
… especially in poultry processing to control food-borne pathogens. Upsets of biological wastewater treatment processes and failures of whole effluent toxicity (WET) tests have been reported as potentially caused by the excessive use of PAA solutions. However, information related to the fate …

Development of gold nanoparticles based lateral flow assay for detection of food and water-borne pathogens
Food and water are two of the necessities required for survival. With increasing global population, urbanization, and climate change, to name a few, the strain on these two precious resources puts pressure on health as well as the economic sector. Microbial contamination of food and water can lead …

Copper tolerance of Listeria monocytogenes strain DRDC8.
… monocytogenes is one of the most important food-borne pathogens due to the severity of the disease it can cause. While the virulence factors required for effective colonisation and infection of mammalian hosts have been well described, other genes may modulate disease persistence. For L. …

Deciphering host-parasite molecular networks mediating resistance to toxoplasma gondii
… is the second leading cause of death due to food-borne pathogens. Current drugs against T. gondii are limited by hypersensitivity and toxicity and are ineffective against the encysted stage of the parasite. Coupled with the lack of T. gondii vaccine for humans, there is an urgent need to …

Agent-based and contact network modeling applications for Escherichia coli transmission in commercial feedlot settings
… coli (STEC) are recognized as a major food-borne pathogens with outbreaks, human infections, and occasional deaths associated with the consumption of contaminated foods. Cattle are recognized as a primary reservoir for STEC, though the transmission dynamics of STEC in feedlot cattle are …
