** FILE ** Shelves on the peanut butter aisle at an Atlanta supermarket are bare after jars of Peter Pan Peanut Butter were pulled from stores in Atlanta in this Feb. 16, 2007 file photo. When ConAgra Foods Inc. recalled its Peter Pan-brand peanut butter, it also recalled Great Value peanut butter it made for Wal-Mart Stores Inc. But increased outsourcing can complicate food recalls as companies are increasingly paying others to make the foods we eat _ or the ingredients in them _ and then selling it under multiple brand names.
