USDA Researchers Develop Camera System to Detect Active Shiga Toxin

Scientists at USDA’s Agricultural Research Service Western Regional Research Center in Albany, CA, have come up with a less-expensive way to detect biologically active Shiga toxin, a product of pathogenic Escherichia coli serotype O157:H7. It is estimated that E. coli O157:H7 causes 73,000 cases of food poisoning and more than 60 deaths in the United States each year…. Continue Reading
