Severe obstructive lung disease has been identified in people who work with flavoring chemicals containing diacetyl, including butter flavoring. Animal studies suggest that some flavoring chemicals similar to diacetyl, such as 2,3-pentanedione, may also be a hazard. Cases of severe lung disease have occurred in microwave popcorn plants and flavoring production plants. Lung biopsies in some affected people have shown the presence of a rare condition; constrictive bronchiolitis obliterans (also referred to as constrictive bronchiolitis, obliterative bronchiolitis, and bronchiolitis obliterans). In some workers, fixed airways obstruction has been severe enough to be fatal.
