Packages of Betty Crocker cake mix have been added to the General Mills recall of Gold Medal Flour, Signature Kitchens, and Wondra Flour. It's due to due to E. Coli contamination. General Mills says the source is likely a supplier who used flour produced at a plant in Kansas City. The products were sold in the U.S. and Canada.

The company reminds consumers not to eat uncooked cake batter.

From General Mills:

Two flavors of cake mix – Betty Crocker Delights Super Moist Party Rainbow Chip Cake Mix (called Betty Crocker Super Moist Rainbow Bit

Cake Mix in Canada) and Betty Crocker Delights Super Moist Carrot Cake Mix have been added to the recall. A General Mills supplier used Wondra flour implicated in the July 1, 2016 recall to manufacture the flavor chips (or bits) used in these two recalled cake mix flavors.  General Mills continues to collaborate with health officials to investigate a multistate outbreak of E. coli O121 connected to several brands of flour.
