A $25 million research project that has already produced improved detection and eradication techniques for toxic E. coli is beginning its seventh year with the continued goal of reducing public health risks. Scientists and educators at 18 institutions have been working on the project, funded with a grant from the U.S. Department of Agriculture that… Continue Reading

Cold plasma proving to be hottest new food safety treatment

cold plasma blueberry research

Described as a “purple blow torch” by food safety scientists, cold plasma treatment can kill 99.9 percent of norovirus on blueberries without damaging the delicate fruit, giving a food safety boost to the so-called superfood. Brendan Niemira, a microbiologist at the U.S. Department of Agriculture’s Eastern Regional Research Center in Wyndmoor, PA, and a team… Continue Reading

Those nerds at the FDA and CDC have been at it again, thank goodness. They took a crazy close look at the Listeria outbreak traced to Blue Bell Creameries ice cream and found evidence supporting the long-held assumption that very small amounts of the pathogen can lead to serious infections in some groups of people. Though… Continue Reading

Ten of the good guys and gals in the battle to defeat foodborne illness just got $2 million from the Center for Produce Safety to help with seek-and-destroy efforts focused on pathogens’ pathways to people via produce. While fresh fruits and vegetables are undeniably vital for good health, many of them pose a greater risk… Continue Reading

Study finds ‘amazing’ bacterial diversity in transported raw milk

Dairy cows

Researchers at the University of California-Davis report that samples of raw cow’s milk shipped by tanker truck for processing show “amazing bacterial diversity” which varies by season. Their findings were reported Aug. 23 in mBio, the online, open-access journal of the American Society of Microbiology. The researchers sampled and analyzed raw cow’s milk from 899 tanker trucks as they… Continue Reading
