McDonald’s says Quarter Pounders will return to its menu at all of its restaurants after it said testing ruled out beef patties as the source of an E. coli poisoning outbreak tied to the burgers.
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, federal health officials said.
The CDC said the source has not been determined but said many of the sickened people had reported eating sandwiches with romaine lettuce at Wendy's restaurants in four Midwestern states.
