E. Coli Outbreak Tied to McDonald’s Widens to 75 People in 13 States

The number of people hospitalized from the E. coli outbreak linked to raw onions on McDonald’s Quarter Pounder hamburgers has more than doubled, and those reporting they have been sickened rose to 75, the Centers for Disease Control and Prevention reported on Friday.

Illnesses of people ranging in age from 13 to 88 were reported in 13 states. Additionally, the C.D.C. said a second person had developed the life-threatening condition associated with E. coli called hemolytic uremic syndrome.

While cases had been originally clustered in the Mountain West, updated data from the C.D.C. now shows cases in Michigan, Washington and Oregon. It is still unclear whether those people ate at McDonald’s in their home states or stopped at one of the restaurants while traveling. The Washington state health department said that a resident of the state fell ill after a trip to Colorado.

One older person in Colorado has died in the outbreak. The C.D.C. said the most recent illness occurred on Oct. 10, although the agency said more cases could be reported because it can take three to four weeks to determine whether an illness is part of the outbreak.

Federal health officials said they hoped the risk to consumers would now be lower because onions have been recalled in many of those states, and many other fast-food chains including Taco Bell, KFC, Pizza Hut and Burger King also decided to stop offering onions in their menu items as a precautionary measure.

News of the outbreak broke this week when the C.D.C. issued a food safety alert, as McDonald’s pulled its Quarter Pounders from locations in 10 states.
