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 of scientists already demonstrated that cold plasma (CP) can kill pathogens such as Salmonella and E. coli on blueberries.
