Public health officials are investigating a deadly E. coli outbreak across several states, where most people say they had eaten a McDonald’s Quarter Pounder hamburger before becoming sick, according to a CDC notice.

The outbreak has infected 49 people, hospitalized 10, and killed one so far.

It notes that the outbreak may not be limited to the states with known illnesses, and the number of sick people is likely much higher than 49, as people are likely recovering without medical care or testing for E. coli.

Investigators are still determining which specific ingredient is contaminated, and whether contaminated ingredients went to other restaurants or stores.
