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.
Symptoms of STEC infection include severe stomach cramps, diarrhea (which is often bloody), and vomiting. If there is fever, it usually is not very high. Most patients’ symptoms improve within 5–7 days, but some patients go on to develop hemolytic uremic syndrome (HUS), usually about a week after the diarrhea starts. The classic triad of findings in HUS are acute renal damage, microangiopathic hemolytic anemia, and thrombocytopenia.
