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, according to the Associated Press. McDonald’s shares dropped 9% in after-hours trading Tuesday after the CDC’s announcement.
Infections were reported between Sept. 27 and Oct. 11, in Wisconsin, Colorado, Iowa, Kansas, Missouri, Montana, Nebraska, Oregon, Utah, and Wyoming.
In a statement, McDonald’s officials said that initial findings suggest that some illnesses are linked to onions sourced from a single supplier. The company has halted distribution of the slivered onions and temporarily removed the Quarter Pounder from menus in the affected states, and also in portions of Idaho, Nevada, New Mexico, and Oklahoma.
The news comes in an already tough year for the Chicago-based McDonald’s chain. Its global same-store sales fell for the first time in nearly four years in the second quarter as inflation-weary customers skipped eating out or chose cheaper options. The company responded with a $5 meal deal, which was introduced at U.S. restaurants in late June and was recently extended through December. The deal doesn’t include the Quarter Pounder.
