The role of microorganisms in various forms of respiratory diseases attributed to grain dust and other factors that might contribute to the health effects of the dust are reviewed. Grain dust is a complex material composed of plant fragments, microorganisms and their metabolites, insects and mites and their products, the excreta of birds and rodents, and residues of pesticides. Occupational lung disease has long been recognized in the grain industry. These range from bronchitis and chronic obstructive pulmonary disease, through allergic rhinitis and asthma, extrinsic allergic alveolitis and organic dust toxic syndrome to febrile reactions to bacterial endotoxins and, perhaps, the effects of inhaled mycotoxins and infection. The components of grain dust that cause some of these symptoms are well known and often involve hypersensitivity to spores of fungi or actinomycetes and to mites and insects or their products. However, the aetiology of others is not well understood although allergy may sometimes play a part and there may be non-specific reactions to the dust or interactions between different components.
