E. coli food poisoning linked to McDonald’s Quarter Pounder hamburgers has sickened at least 49 people in 10 states, including one person who died and 10 who were hospitalized, federal health officials said Tuesday. The death was reported in an older person in Colorado, and one child has been hospitalized with severe kidney complications, the U.S. Centers for Disease Control and Prevention reported. Infections were reported between Sept. 27 and Oct. 11, in Colorado, Iowa, Kansas, Missouri, Montana, Nebraska, Oregon, Utah, Wyoming and Wisconsin. Colorado has the most cases, 27, followed by Nebraska with nine. Everyone interviewed in connection with the outbreak had reported eating at McDonald's before falling ill and most mentioned eating Quarter Pounder hamburgers, the CDC said. The U.S. Agriculture Department, the Food and Drug Administration and state health officials are also investigating. The specific ingredient tied to the outbreak has not been identified, but investigators are focused on onions and beef. McDonald's reported to the CDC that it had removed slivered onions and beef patties used for Quarter Pounders from stores in the affected states. The burgers may be temporarily unavailable in those states. MORE: https://www.wthr.com/article/news/nation-world/mcdonalds-e-coli/507-8e1128f4-ebcd-42aa-9649-e7f4e5deca47
