49 people from 10 states have gotten sick from the same strain of E. coli O157:H7. Most sick people are from Colorado (27) or Nebraska (9).
10 people have been hospitalized. One older person in Colorado has died. Additionally, one child is hospitalized with complications of hemolytic uremic syndrome, or HUS.
Everyone interviewed has reported eating at McDonald's before their illness started, and most specifically mentioned eating a Quarter Pounder hamburger.
The specific ingredient linked to illness has not yet been identified, but investigators are focused on two ingredients in particular: fresh slivered onions, and fresh beef patties.
