King Arthur Flour has issued a voluntary recall.
Officials from the Norwich-based company say pea-sized polyurethane balls, which are used in the mixing process, ended up in a limited number of bags of Unbleached Bread Flour and Unbleached All-Purpose Flour.
The affected bags have a "best by" date between December and January of this year. Anyone who has purchased the 5-pound bags can return them for a full refund.
More information is available on the company's website.
