Check the flour in your cupboard.

King Arthur Flour of Vermont is recalling bags of flour due to the possible presence of small blue polyurethane balls that are used in the sifting process.

The balls are 7-9 mm, have a smooth surface with no sharp edges and are made from food-grade material.

Because the balls are bright blue and about half the diameter of a dime, they are easily seen in the flour, officials said.

The bags were sold at Target and Walmart.

The recall is for 5-pound bags of King Arthur Unbleached All-Purpose Flour and King Arthur Unbleached Bread Flour. Look for the best if use by dates and lot codes. If they are printed on the top of the bag, then the product is not part of the recall. If they are printed on the side of the bag beneath the nutrition panel, then look for the UPC code and the following information:

King Arthur Unbleached All-Purpose Flour, 5-pound bag, UPC 0-71012-01050-9 with the combination of both the Best Used By Date plus Lot Code beneath the nutrition facts panel as listed below:
