The three companies that sell Orville Redenbacher, Act II, Pop Secret and Jolly Time microwave popcorn are planning to revamp their microwave popcorn formulations to remove diacetyl, which was been linked to cases of bronchiolitis obliterans, a rare life-threatening disease often called popcorn lung, the Associated Press reported on Wednesday.
ConAgra Foods Inc., General Mills Inc. and the American Pop Corn Co. all said they would make the change, citing safety concerns, the AP said.
