The Centers for Disease control is investigating an E. coli outbreak in McDonald’s Quarter Pounder hamburgers sold in 10 states.

At least 49 people have been sickened as of Tuesday, Oct. 22, apparently after eating the quarter-pounders. A map provided by the CDC shows most of the cases are in Colorado, Utah, Wyoming and Nebraska. There have also been reports in Oregon, Montana, Kansas, Missouri, Iowa and Wisconsin. At least 26 people were sickened in Colorado alone.
