WASHINGTON (AP) _ A Massachusetts company is recalling batches of a gourmet pickled pepper labeled as sulfite-free but that actually contain sulfites _ posing a serious, even life-threatening, risk to people allergic to that ingredient.

Recalled are 4,200 jars of Zorba Natural Pepperoncini labeled as sulfite-free and sold in 15-ounce jars that bear, on the lid, the production codes OCT1703, OCT1803 and NOV703.

They were sold in Arizona, Connecticut, Florida, Georgia, Iowa, Pennsylvania, Texas, Washington and Wisconsin.

People with sulfite allergies should not eat the recalled peppers but return them to the store of purchase for a refund.

No illnesses have been reported, said manufacturer Orleans Packing Co., which said the product was mislabeled in a temporary breakdown in packaging processes.
