One person has died and 10 have been hospitalized in a multistate outbreak of Escherichia coli infections linked to McDonald’s Quarter Pounders, the CDC said Tuesday.

There have been 49 cases overall in 10 Mountain West states — most in Colorado (27) and Nebraska (nine), according to the CDC.

All 49 people were infected with the same strain of Shiga toxin-producing E. coli O157:H7, the agency reported. The cases include a child hospitalized with hemolytic uremic syndrome, a serious condition that affects the kidneys, which can be a complication of this type of E. coli infection.

According to the CDC, every person involved in the outbreak reported eating McDonald’s before they became sick, and most said they had a Quarter Pounder burger.

McDonald’s removed slivered onions and beef patties used in Quarter Pounders from stores in the 10 states where cases have been reported, although no specific ingredients have been identified as the cause of the infections, the CDC said.

Symptoms of E. coli infection include diarrhea, fever (temperature higher than 102°F), excessive vomiting and dehydration, the agency noted. People with the type of E. coli infection identified in this outbreak often experience bloody diarrhea, the CDC said.
