Continental Mills’ Krusteaz Blueberry Pancake Mix and three flavors of Betty Crocker cake mixes are the latest products affected by a large recall of potentially tainted flour manufactured at a General Mills Facility.

The possible contaminant is Shiga toxin-producing E. coli (STEC O121), which also may be present in a handful of other previously recalled General Mills flour products, including Gold Medal All Purpose Flour, Gold Medal Wondra Flour and Gold Medal Self-Rising Flour.

According to the Food and Drug Administration (FDA), the recall of Krusteaz Blueberry Pancake Mix affected only specific lots, which were manufactured between April 2016 and June 2016. Those products are:  Krusteaz Blueberry Pancake Mix 28 oz. carton with a best by date code between 3/30/2018 and 6/16/2018, and a UPC code 041449001289; and Krusteaz Blueberry Pancake a 3.5 lb. bag, with a best by date code between of 4/27/2018 to 4/28/2018, with a UPC code 041449001487.

The flavors of cake mixes include Betty Crocker Delights Super Moist Party Rainbow Chip Cake Mix, which is called Betty Crocker Super Moist Rainbow Bit Cake Mix in Canada.

General Mills’ initial flour recall was issued May 31, and since then 42 people from 21 states have been sickened and 11 have been hospitalized. No deaths have been reported.

Symptoms of STEC infection include often-bloody diarrhea and abdominal cramps that exhibit an average of three to four days after swallowing the germ.
