The Missouri Department of Health and Senior Services (DHSS) has become aware of several cases of diarrheal illness from northwest Missouri, possibly caused by Shiga-toxin producing Escherichia coli (STEC), including one confirmed as E. coli O103. These may be related to the consumption of locally-produced, raw (unpasteurized) dairy products.

DHSS recommends that any person who has signs or symptoms of STEC infection seek medical care. Health care providers should evaluate patients adequately to determine if testing for STEC infection is warranted.
