“In July 2016, laboratory testing by General Mills and FDA isolated STEC (Shiga toxin-producing Escherichia coli) 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.
This investigation is ongoing. CDC will update the public when more information becomes available.”
