Farmers are usually exposed to a wide variety of noxious organic or chemical substances. This explains why agriculture is probably one of the occupations where prevalences of respiratory diseases are the highest. Some diseases such as extrinsic allergic alveolitis, allergic asthma, silo filler's disease or pesticides-related fibrosis are classic and well described. Others, more recently identified although probably more frequent, remain often unrecognized. This is notably the case of agricultural chronic bronchitis and of organic dust toxic syndrome. Sometimes, these respiratory pathologies are intricate and lead to a complex presentation where signs of irritation or inflammation of the respiratory tract, bronchial hyperreactivity and chronic bronchial obstruction are mixed.
农民通常会接触到各种各样有害的有机或化学物质。这就解释了为什么农业可能是呼吸系统疾病患病率最高的职业之一。一些疾病，如外源性过敏性肺泡炎、过敏性哮喘、谷仓装料工病或农药相关纤维化，都是典型且有充分描述的。其他一些疾病，虽然最近才被发现，但可能更为常见，却常常未被识别。农业慢性支气管炎和有机粉尘中毒综合征尤其如此。有时，这些呼吸道疾病错综复杂，会导致一种复杂的症状表现，其中呼吸道刺激或炎症、支气管高反应性和慢性支气管阻塞的症状相互交织。
