Title Characterization of respiratory exposures at a microwave popcorn plant with cases of bronchiolitis obliterans
Bibliographic information Mar. 2005, Vol.2, No.3, p.169-178. Illus. 22 ref.
Abstract Eight former workers from a popcorn packaging plant were reported to have severe obstructive lung disease consistent with bronchiolitis obliterans. Investigations into respiratory exposures were carried out at the plant. Air samples were collected to assess airborne particulate concentrations, particle size distributions, endotoxins, nitrogen oxides and other chemicals. Bulk corn and flavoring components were also analyzed for endotoxins and culturable bacteria and fungi. Findings confirm that workers involved in popcorn packaging can be exposed to a complex mixture of volatile organic compounds from flavouring ingredients. Animal studies show that diacetyl can cause airway epithelial injury, although the contribution of other specific compounds associated with obstructive respiratory disease remains unresolved.
