CDC Declares End to McDonald's E. Coli Outbreak Linked to Onions

The CDC announced the end of a lethal E. coli outbreak linked to slivered onions in McDonald's Quarter Pounder burgers, which resulted in one death and 104 infections across 14 states. McDonald's has removed contaminated products from its supply chain and invested $100 million in marketing to restore its image. The outbreak primarily affected Colorado and Nebraska, with the company pausing sales and switching suppliers to address the issue. No new cases have been reported since October 22.
