Abstract

Background: Exposure to organic dust is a well-known hazard for farm animal workers leading to respiratory diseases. Organic dust exposure has not been adequately evaluated in environmental settings in relation to veterinarians. Objective: To investigate inhalable dust, endotoxin, and β-(1 → 3)-glucan exposure among caretakers, veterinarians, and veterinary students. Task-based determinants of exposure were studied. Methods: This study investigated the exposure during veterinary education in the ruminant and poultry clinics. Dust measurements were performed using the conical inhalable samplers (CIS). Endotoxin and β-(1 → 3)-glucan were determined by the kinetic limulus amebocyte lysate (LAL) assay and inhibition enzyme immunoassay (EIA), respectively. Determinants of exposure were identified by multiple linear regression analysis. Results: Personal exposure levels of dust, endotoxin, and β-(1 → 3)-glucan were higher for poultry [geometric mean (GM): dust, 1.32 mg m(-3) (below the lower limit of detection (
