Signs and Symptoms
Multistate Outbreak of Shiga toxin-producing Escherichia coli Infections Linked to Flour (Final Update)
Posted September 29, 2016 12:45PM EST
Although the outbreak investigation is over, illnesses are expected to continue for some time. The recalled flour and flour products have long shelf lives and may still be in people’s homes. Consumers who don’t know about the recalls could continue to eat the products and get sick. A list of the recalled products and how to identify them is available on the Advice to Consumers page.
What are the signs and symptoms?
- People usually get sick from Shiga toxin-producing E. coli (STEC) 2-8 days (average of 3-4 days) after swallowing the germ.
- Most people infected with STEC develop diarrhea (often bloody) and abdominal cramps.
- Most people recover within a week.
- Some illnesses last longer and can be more severe, resulting in a type of kidney failure called hemolytic uremic syndrome (HUS).
- HUS can occur in people of any age but is most common in young children under 5 years, older adults, and people with weakened immune systems.
- Symptoms of HUS can include fever, abdominal pain, pale skin tone, fatigue and irritability, small, unexplained bruises or bleeding from the nose and mouth, and decreased urination.
- People who experience these symptoms should seek emergency medical care immediately.
- STEC infection is usually diagnosed by testing a stool sample.
