BACKGROUND: Toxic pneumonitis or Organic Dust Toxic Syndrome (ODTS) is a common, usually self-limiting condition among agricultural workers, occurring after high level exposure to agricultural dust. CASE REPORT: We describe the case of a 68-year-old smoker and farmer who became ill with dyspnea, flu-like symptoms, and hypoxia after cleaning out a grain bin. RESULTS: Chest radiograph was normal. He was treated with steroids, antibiotics, and oxygen supplementation and recovered over 3 months, but continues with lingering exercise intolerance after 2 years. DISCUSSION: Although toxic pneumonitis usually follows a relatively benign course with spontaneous recovery and no permanent sequale it can lead to the exacerbation of underlying lung conditions, resulting in incomplete or delayed recovery. Prevention is aimed at limiting exposure by avoidance, by increasing ventilation in closed spaces and by appropriate use of personal protective equipment.
