E. coli O157:H7 has not been previously associated with eating raw cookie dough. The CDC, state health departments, and federal regulatory partners are working together in this ongoing investigation.
Most people infected with E. coli O157:H7 develop diarrhea (often bloody) and abdominal cramps 2-8 days (average of 3-4 days) after swallowing the organism, but some illnesses last longer and are more severe. Infection is usually diagnosed by culture of a stool sample. Most people recover within a week, but some develop a severe infection. A type of kidney failure called hemolytic uremic syndrome (HUS) can begin as the diarrhea is improving; this can occur in people of any age but is most common in children under 5 years old and the elderly.
