(AP) -- State health officials say six of 13 confirmed cases of E. coli in the state are linked to consumption of unpasteurized milk or raw dairy products from a farm in Howard County.

Health officials said Monday the remaining seven people with confirmed E. coli infections did not consume raw dairy from the farm.

Gena Terlizzi, spokeswoman from the state health department, says all potential sources of exposure are being considered in those cases.

Three cases of E. coli have been reported in Boone County, including a 2-year-old child who has been hospitalized for two weeks. Other E. coli cases were confirmed in Camden, Clark, Cooper, Howard and Jackson counties.
