Super-shedders, cattle shedding at least 104 colony forming units (CFU) of E. coli O157:H7, elevate risks of contaminating the food chain and maintaining the organism in cattle populations. As detecting supershedders in cattle populations is laborious and time-consuming, a study was conducted to evaluate the role of hide and pen-floor contamination by model super shedders (MSS) in transmission ...

hazards in food. Examples include foodborne pathogens such as salmonella, naturally occurring mycotoxins, such as aflatoxin, or pesticide residues. These hazards can pose acute risks (consumers become ill immediately) or chronic risks (consumers’ risk of chronic illness is enhanced). Some hazards are easily controlled or detected while others occur naturally and may be difficult for producers t...

The fi ght against foodborne illness is a fi ght against probability. The US Centers of Disease Control and Prevention (CDC) reported that each year one in six Americans (approximately 48 million) are affected by foodborne illnesses and there are 3000 deaths due to the consumption of tainted food products (CDC 2011 ). Recent incidences of foodborne outbreaks, including the most recent Listerios...

tance and use. In recent years, the U.S. food industry has made great advances toward improving the safety of our nation’s food supply. A recent report from the Centers for Disease Control and Prevention revealed the incidence of Escherichia coli O157:H7 infections are down 36% from 2002 to 2003 (CDC, 2004). Despite this, foodborne diseases continue to present unacceptable public health risks t...

ONE HUNDRED AND EIGHTY PATIENTS with positive cervical smears, but no clinical evidence of invasive cancer, elected to be sensitized to DNCB and subsequently have DNCB applied to the cervix. Twentyfive patients did not become sensitized to DNCB. Of the remaining 155 patients, the smear test remained positive in 105, but became negative in 50. Fourteen of the 50 patients were subsequently operat...

The agar diffusion assay was used to examine the effect of pH on the ability of alkaline salts of 3 fatty acids (FA) to inhibit growth of bacteria associated with poultry processing. FA solutions were prepared by dissolving 0.5 M concentrations of caprylic, capric, or lauric acid in separate aliquots of 1.0 M potassium hydroxide (KOH). Citric acid was added to the FA-KOH mixtures to reduce the ...

climate change around the world is now a reality that has adverse effects on the environment and human health. there is little information about the effect of climate change on food systems, especially seafood from the farm to the table. the aim of this study was to review the fundamental effects of climate change on seafood safety and human health. climate change is expected to increase chemic...
