Public health officials in multiple states, including Utah, are investigating an outbreak of E. coli O157:H7 infections. Most people in this outbreak are reporting eating the Quarter Pounder hamburger at McDonald’s before becoming sick. McDonald’s stopped using slivered onions on the Quarter Pounder hamburger in some states to try to prevent more people from getting sick. At this time, no cases have been reported in the Weber-Morgan Health Department.
Epidemiologic and traceback information show that fresh, slivered onions are the likely source of illness in this outbreak. Taylor Farms, the supplier of slivered onions to the affected McDonald’s locations also recalled onions. Food service businesses were contacted directly by Taylor Farms. The likelihood of contaminated onions still being available for sale is low.
