Colorado has reported five cases of an E. coli strain linked to raw cookie dough, and one person has developed a severe complication.

Health officials say two cases of E. coli were reported in Douglas County and one each in Denver, Jefferson and Weld counties.

Four reported eating raw cookie dough in the week before they became ill. The fifth hasn't been interviewed.

Two people have been hospitalized. One has a complication called hemolytic uremic syndrome. Federal health officials say the syndrome can cause anemia and can also cause kidney damage in children.

Nestle USA has recalled its Toll House refrigerated cookie dough after a number of illnesses were reported by people who ate the dough raw.
