E. coli Outbreak Linked to McDonald's Investigated

The U.S. government has concluded its investigation into an E. coli outbreak linked to McDonald's Quarter Pounder hamburgers, which resulted in 104 reported cases across 14 states, including one death in Colorado. The outbreak was traced back to yellow onions supplied by Taylor Farms, which initiated a recall on October 22 after the first illness reports emerged in mid-September. The Centers for Disease Control and Prevention (CDC) noted that the actual number of cases could be higher, as many individuals may not have sought medical attention. McDonald's halted the use of slivered onions and temporarily withdrew the Quarter Pounder from its menu in affected areas but resumed normal operations after identifying an alternate supplier. There have been no new cases reported since October 21, 2023, and federal health officials stated there is no ongoing food safety concern. The outbreak significantly impacted McDonald's sales, prompting the company to spend $100 million to restore customer traffic.
