Fourteen people have been sickened by E. coli O157:H7 in central Missouri, and seven now report consuming unpasteurized milk from the same farm before becoming ill, according to Gena Terlizzi, office of public information, Missouri Department of Health and Senior Services.

Investigators at the Missouri Department of Health and Senior Service (DHSS) have not yet identified a definite source of the outbreak, but a farm in Howard County is under investigation.

Terlizzi, in an email, said the other 7 people with confirmed E. coli infections reported that they did not consume raw milk from the farm prior to the onset of their illnesses.

A 2-year-old now hospitalized for more than two weeks is being treated for kidney failure.
