Idea to reality: In response to national health initiatives, the dairy industry is exploring ways to reduce the sodium content of cheese without compromising food safety and quality. Salt helps limit the growth of harmful bacteria in cheese. The industry needed to know if reducing the sodium content of processed American cheese slices would increase the survival of Listeria — a food-borne pathogen that can make people sick. AURI’s role:… Read More »AURI and the cheese industry
Reducing the salt content of American cheese slices doesn’t increase the survival of Listeria monocytogenes, a University of Minnesota study has found.
Listeria is a common bacteria found in soil, water, and some animals, including cattle, according to the U.S. Health Department’s website: Foodsafety.gov. It can also be present in raw milk and foods made from raw milk. Unlike many food pathogens, Listeria can grow in cold temperatures in the refrigerator. It is killed by cooking and pasteurization. Common sources of Listeria include ready-to-eat deli meats, hot dogs, meat spreads, unpasteurized dairy… Read More »What is Listeria?
