Fresh onions are the probable source of an E coli outbreak at McDonald’s restaurants that has sickened 49 people and killed one, the US Department of Agriculture said, alarming fast food chains using the ingredient.
Taylor Farms, a supplier for McDonald’s, the biggest US burger chain, recalled several batches of yellow onions produced in a Colorado facility, according to a memo on Wednesday by US Foods, one of the largest suppliers of food service operations in the country.
