McDonald's shares dropped in premarket trading Wednesday morning after the Centers for Disease Control and Prevention said an E. coli outbreak linked to McDonald's Quarter Pounder burgers has led to 10 hospitalizations and one death.
"Most" sick people reported eating a McDonald's Quarter Pounder, the CDC added.
McDonald's shares dropped about 7% in trading before the market opened Wednesday.
In a statement Tuesday, McDonald's said it is taking "swift and decisive action" following the E. Coli outbreak in certain states.
McDonald's has instructed all local restaurants to remove slivered onions from their supply and has paused the distribution of that ingredient in the affected area.
