Silo-filler's disease

Silo-Filler's disease, not to be confused with farmer's lung (associated with inhalation of biologic dusts), is an occupational lung disease associated with toxic gas inhalation. The disease results from inhalation of nitrogen dioxide (NO2) gas from fresh silage. The presentation is variable depending on level of exposure. Often the gas penetrates throughout the lung and if severe can manifest as a form of Acute Respiratory Distress Syndrome, such as significant pulmonary edema, hyalinized alveolar membranes, congestion and other respiratory illnesses.
