Minnesota health officials say the number of E. coli cases linked to raw milk or other dairy products from a Gibbon farm has grown to eight.

The Minnesota Department of Health said Friday three additional cases have been identified. Two of those cases are school-aged children who consumed milk from the Hartmann Dairy Farm.

The Health Department said both cases had E. coli with the same DNA fingerprint as five earlier cases associated with dairy products from the Hartmann farm. The other new case was an infant living in the same household as one of the earlier five cases, but a stool sample was not available for genetic fingerprinting.

The farm earlier disputed allegations that its unpasteurized milk caused the E. coli outbreak.
