Illnesses started on dates ranging from December 21, 2015 to June 25, 2016. Ill people range in age from 1 year to 95, with a median age of 18. Eighty percent of ill people are female. Thirteen ill people have been hospitalized. One person developed hemolytic uremic syndrome, a type of kidney failure. No deaths have been reported.
Illnesses that occurred after June 29, 2016, might not yet be reported due to the time it takes between when a person becomes ill and when the illness is reported to CDC. This takes an average of 2 to 3 weeks. Please see the Timeline for Reporting Cases of E. coli O157 Infection for more details.
In July 2016, laboratory testing by General Mills and FDA isolated STEC O26 from a sample of General Mills flour. Whole genome sequencing (WGS) showed that the STEC O26 isolated from the flour sample was closely related genetically to isolates from an ill person. The flour tested was not included in the earlier General Mills recalls.
On July 25, 2016, General Mills expanded its recall to include more production dates. CDC recommends that consumers, restaurants, and retailers do not use, serve, or sell the recalled flours.
