JEFFERSON CITY — Missouri health officials said they have narrowed their investigation of E.coli in Missouri to 12 cases with similarities.
The state Department of Health and Senior Services previously reported 15 confirmed cases of E. coli, mostly in central Missouri.
A department spokeswoman said the investigation will now concentrate on 12 cases with similar lab results, geographic proximity and case history.
The Columbia Tribune reported that eight people recently sickened by a strain of E. coli consumed raw milk from a farm in Armstrong. But samples of raw dairy materials taken from the Howard County farm all tested negative for the bacteria.
Columbia/Boone County health officials said one of four cases in the county, a 2-year-old child, remains hospitalized.
