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.

Master Chef Fabio Bertoni, of Il Forno Bertoni bakery in Montichiari, mixes some flour as he teaches a bread making technical class during the advanced course of Italian cuisine at the Alma International School of Italian Cuisine in Colorno on January 28, 2006 in the outskirts of Parma, Italy. The Alma school was founded by Italian Master Chef Gualtiero Marchesi, with the aim of creating professionals in Italian cuisine at the very highest level. The school calls on a highly respected body of tutors, some of the very best connoisseurs of Italian produce, local wine, pastry chefs, culinary historians and nutrition experts, to train the very top level of chefs in the catering industry worldwide.
