Multistate Outbreak of Shiga toxin-producing Escherichia coli O157:H7 Infections Linked to I.M. Healthy Brand SoyNut Butter (Final Update)

Posted May 4, 2017 11:45 AM EST

Although the outbreak investigation is over, illnesses may continue for some time. The recalled SoyNut Butter products have long shelf lives and may still be in people’s homes or in institutions. People who don’t know about the recalls could continue to eat the products and get sick. The recalled products are listed on the Recalls & 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 one 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.
