Animal handlers' lung

Last edited: 4/14/2026

Overview

Animal handlers' lung, also known as hypersensitivity pneumonitis, is an occupational lung condition affecting individuals who work closely with animals, particularly in environments with high levels of organic dust, endotoxins, and microbial antigens. It manifests as an immune-mediated inflammatory response following inhalation of these antigens. 1525

Diagnosis

  • Clinical Presentation: Symptoms include dyspnea, cough, fever, and fatigue, often triggered by exposure to animal environments.
  • Diagnostic Tests:
  • - Pulmonary Function Tests (PFTs): To assess airflow obstruction and lung volumes. - High-Resolution Computed Tomography (HRCT): For characteristic interstitial lung patterns. - Bronchoalveolar Lavage (BAL): To identify cellular infiltrates and markers of inflammation. - Serological Testing: For specific antibodies against environmental antigens.
  • Environmental Exposure Assessment: Identifying potential sources of antigen exposure. 1525
  • Management

  • Primary Prevention:
  • - Exposure Reduction: Minimize contact with antigen sources through improved ventilation, personal protective equipment (PPE), and hygiene practices.
  • Secondary Prevention:
  • - Avoidance: Temporarily removing the individual from the exposure environment.
  • Medical Management:
  • - Corticosteroids: High-dose oral or intravenous corticosteroids for acute exacerbations. 15 - Immunosuppressive Agents: In refractory cases, consider agents like methotrexate or azathioprine under specialist guidance.
  • Supportive Care: Oxygen therapy, hydration, and symptomatic relief measures. 15
  • Special Populations

  • Occupational Risks: No specific differentiation noted for pregnancy, pediatrics, or elderly populations in the provided abstracts; however, heightened vigilance is advised in all high-risk occupational groups. 1525
  • Key Recommendations

  • Implement strict environmental controls and use of PPE to minimize antigen exposure in animal handling environments. (Evidence: Moderate) 15
  • Early recognition and removal from exposure are critical in managing acute episodes of animal handlers' lung. (Evidence: Moderate) 15
  • Corticosteroids should be considered as first-line therapy for acute exacerbations of hypersensitivity pneumonitis. (Evidence: Moderate) 15
  • Regular health monitoring and education on symptoms and preventive measures are essential for at-risk workers. (Evidence: Expert opinion) 15
