Following the Oct. 3 recall for its Unbleached All-Purpose Flour, King Arthur Flour, Inc. has issued a recall for an additional three lots of flour produced by ADM Milling Co. because it may also be contaminated with E. coli.

The recall affects five-pound bags of Unbleached All-Purpose Flour with a Best Used by Date of 12/09/19 and product lot codes of L18A09A and L18A09C, and a Best Used by Date of 01/08/20 with a product lot code of A19A08A.

Consumers that have purchased the contaminated flour should throw it away. A refund or replacement can be issued by submitting a form to or by calling the King Arthur Flour Consumer Hotline at 1-866-797-9178.

King Arthur Flour has not received any reports of illness related to the flour recall. The company said in a statement that it is “committed to providing our consumers safe and superior products.”

Consumers are urged to wash their hands, work surfaces, and utensils when coming in contact with raw dough products or flour. Raw dough or batter should never be eaten. According to the Centers for Disease Control, E. coli in raw flour is killed through the heating of baking, frying, sautéing, or boiling.
