Mushroom Compost Worker's Lung

Abstract

This study draws attention to difficulties in the diagnosis and the understanding of the mechanism of action of mushroom compost worker's lung. Descriptions are given of 4 workers in one factory who developed acute respiratory failure within a 6-month period; 13 others who were unaffected were also studied. Serological investigation appears to be largely unhelpful, and the evidence against the condition being included amongst the extrinsic allergic alveolitides is discussed. A detailed clinical and occupational history is essential for diagnosis.
