Title Bronchiolitis obliterans in an animal feed worker
Bibliographic information Sep. 1995, Vol.28, No.3, p.437-443. 18 ref.
Abstract A case study is presented of a nonsmoking animal feed production worker who developed severe irreversible airflow obstruction during a 2-year occupational exposure to organic matter, microorganisms, proteolytic enzymes and both amorphous and synthetic silicates. Open lung biopsy demonstrated findings consistent with bronchiolitis obliterans; silicate particles in biopsy specimens suggested a potential link between silicate exposure and pathologic findings. Findings should be considered when evaluating symptomatic patients with occupational exposure to animal feed dusts, in particular amorphous and synthetic silicates.
