AB  - Lung diseases in farmers attributable to their occupation include (a) farmer's lung, caused by exposure to mouldy hay, (b) the asthma caused by exposure to grain dust and (c) silo-filler's disease. Their prevalence in Canada is unknown. Farmer's lung results from inhalation of mould spores in hay; the mechanism is immunologic. The exact cause and mechanism of grain dust asthma are unknown but may be immunologic. Silo-filler's disease is caused by the toxic effects of inhaled nitrogen dioxide.
