Is that the answer blowin’ in the wind, or pathogen drift?

Free-manure

“The answer, my friend, is blowin’ in the wind.” — Bob Dylan The question in the case of food safety is: “What’s blowing in the wind?” Turns out it can be dangerous pathogens such as E. coli, Campylobacter and Salmonella when manure is spread on the land, which is a common agricultural practice. At least that’s… Continue Reading

New Stanford center targets Salmonella with $10M grant

Markus Covert will head the Allen Discovery Center for Multiscale Systems Modeling of Macrophage Infection  at Stanford University.

A new center at Stanford University has Salmonella in its crosshairs, with a $10 million grant to use against the bacteria that causes more than 100 million infections annually. The Allen Discovery Center for Multiscale Systems Modeling of Macrophage Infection will be directed by Markus Covert, an associate professor of bioengineering. The center takes its… Continue Reading

Research links food poisoning to increased suicidal behaviors

ScientistMicroscopeMain

Most people associate food poisoning with physical symptoms, but new research shows a connection between a foodborne parasite and mental/emotional problems, including suicide. Researchers at universities across the country analyzed data collected from 1991 through 2008 and confirmed a relationship, previously theorized, between Toxoplasma gondii (T gondii) and self-directed aggression and other psychiatric disorders, according… Continue Reading

Research shows feedlot link to E. coli O157:H7 on leafy greens

Current guidelines for the minimum distance between cattle feed lots and fresh produce growing fields are likely inadequate to ensure leafy greens are not contaminated with E. coli from dust and manure. “Additional research is needed to determine safe set-back distances between cattle feedlots and crop production that will reduce fresh produce contamination,” according to… Continue Reading

A food safety team at Montreal’s McGill University has been awarded $10 million for a study intended to answer remaining questions about Salmonella and how food growers can better prevent its contamination. The research team, led by McGill Food Safety Associate Professor Lawrence Goodridge, Ph.D., will first sequence the genomes of 4,500 isolates from the 2,500 known Salmonella serotypes —… Continue Reading

Scientists Learn How Listeria Grows on Refrigerated Smoked Salmon

One of the dangers of Listeria monocytogenes is that it can grow on food even in the cold temperatures of the refrigerator, although it does grow more slowly at 40 degrees F or less. Studying how foodborne pathogens adapt in different foods and storage conditions could help scientists develop more efficient control strategies and growth inhibitors. One… Continue Reading

Chicken Flock Study on Salmonella Transmission Makes Novel Discovery

http://www.dreamstime.com/royalty-free-stock-photo-chicken-farm-image22950815

Despite Salmonella being the most common illness-causing foodborne bacteria in the U.S. food system, still very little is known about the precise processes through which the bacterium contaminates and transmits among its most pervasive carriers: chickens. New research from the University of Arkansas, however, is aiming to bridge the gap in knowledge about how Salmonella infects such a large percentage… Continue Reading

Study: Peanuts May Help to Ward Off Some Foodborne Illnesses

ShelledPeanutsMain

Eating the skinless inner kernels of peanuts may improve a person’s gut biota and its ability to ward off E. coli and Salmonella, according to a new study by researchers at the University of Maryland published in the Journal of Food Science. The findings suggest that skinless peanuts could be a beneficial promoter of gut bacteria that will outcompete… Continue Reading
