King Arthur Flour is adding three more lot numbers to a recall it announced last month over its 5-pound bags of Unbleached All-Purpose Flour due to the potential for E.coli contamination.

The company announced Friday that it was notified by ADM Milling Co. that the lot codes were omitted from the original data King Flour provided in its October 3 announcement.

Under this update, consumers are urged to look for lot codes L18A09A and L18A09C wth best used by date 12/09/19.  Also, look for lot code A19A08A with best used by date 01/08/20. 

Those are in addition to this earlier list of the “Best Used By” dates and their associated lot codes for bags with UPC 071012010509. They come in 5-pound and 25-pound bags.
