McDonald's Quarter Pounders return to the menu after testing rules out beef as E. coli source

The video discusses an E. coli outbreak linked to McDonald's, initially thought to be from their beef patties, but later suspected to be from onions supplied by Taylor Farms. McDonald's took swift action by removing Quarter Pounders from the menu and communicating the issue to the public. The CDC assessed the risk to the public as low, but the outbreak affected 75 people across 13 states, with one death. McDonald's stock dropped by 7%, and they extended a value meal promotion to mitigate the impact. Other restaurants like Taco Bell and Illegal Pete's also stopped using onions as a precaution.
