The person who died in Colorado and whose death is connected an E. coli outbreak at McDonald's in multiple states lived in Mesa County. That's according to Mesa County Public Health, which has not released the identity of the deceased person.

Colorado is the only state where a death has been reported, and it is the state with the most cases of people falling ill with E. coli food poisoning linked to McDonald's Quarter Pounder hamburgers.

USDA is also investigating the beef patties on the Quarter Pounder hamburgers.”

Arapahoe County
Chaffee County
El Paso County
Gunnison County
Larimer County
Mesa County
