McDonald’s Quarter Pounders are the likely cause of an E. coli outbreak that has infected 49 people from 10 states and killed one, according to the U.S. Center for Disease Control (CDC).
The CDC issued a food safety alert after everyone interviewed reported eating at McDonald’s before their illness started, and most specifically mentioned eating a Quarter Pounder hamburger.
Investigators are focusing on fresh slivered onions and beef patties as potential sources.
Colorado has 27 cases and Nebraska nine.
Ten people have been hospitalized, and one person in Colorado has died.
