It is important for clinical and investigational purposes that organic dust toxic syndrome be distinguished from acute farmer's lung. Organic toxic dust syndrome (OTDS): a flu-like illness that arises after heavy exposure to organic dust. Many agricultural workers are at risk for developing various respiratory illnesses due to regular exposure to inhaled dusts. Although a producer who has been exposed to silo gases may not experience symptoms, damage to the lungs may still have occurred. HEALTH EFFECTS OF ORGANIC DUST Agricultural workers may develop ODTS after inhaling dust from contaminated organic materials. Mold spores, which are not always visible, are so tiny that 250,000 spores can fit on the head of a pin.

Organic dust toxic syndrome in a child Clin Pediatr (Phila). Organic Dust Toxic Syndrome (ODTS) is a flu-like illness following respiratory exposure to organic dusts. People who have experienced ODTS and who experience additional exposures to organic dust have an increased risk for respiratory problemsand the potential for developing chronic bronchitis. Due to their size, the mold spores easily move into and settle in the lower part of the lungs. Epub 2012 Jan 24.

Organic dust toxic syndrome is a potentially severe flu-like syndrome originally described in farmers, mushroom workers, bird breeders and other persons occupationally exposed to dusty conditions. Cough, hemoptysis (coughing up blood from the respiratory tract), dyspnea (shortness of breath), and chest pain can occur after an exposure to 20 ppm, a moderate level of nitrogen dioxide. It results fromthe inhalation of mold spores from moldy hay, straw, or grain. Workers [Granulomatous diseases and pathogenic microorganism]. 1986; May et al. 1990).
