More than 25,000 cases of tomato-based bread items sold at Trader Joe’s and by other brands have been recalled because of the possible presence of metal, according to a recall notice by the U.S. Food & Drug Administration.

The affected products were sold under brands Trader Joe’s, Frederik’s by Meijer, Harris Teeter, and Fresh and Simple at stores in 10 states, including Texas, and Arizona, California, Connecticut, Florida, Illinois, Michigan, North Carolina, New Jersey and Virginia.

The voluntary recall was initiated by manufacturer Bakkavor in January and on March 23 classified by the FDA as a Class II recall, which means the affected items could lead to “temporary or medically reversible adverse health consequences,” the FDA report said.

Among the various recalled products are more than 20 lots of Trader Joe’s Roasted Tomato and Parmesan Focaccia Bread, sold exclusively at Trader Joe’s with use-by dates between July 26 and Oct. 15.

Also included in the recall were 2,337 cases of HelloFresh Basil Pesto and Mozzarella Pizza, sold under the HelloFresh brand, an E-commerce food delivery brand.

Other products recalled are Frederik’s by Meijer Slow-Roasted Tomato and Shredded Parmesan Cheese Focaccia and Fresh and Simple Roasted Tomato and Parmesan Focaccia.

The metal fragments were discovered by the Charlotte, N.C.-based Bakkavor and traced to roasted tomatoes provided by one of the company’s ingredient suppliers, according to the FDA recall notice.

People who purchased these items are being urged to throw them out or return them for a refund by the place of purchase.
