Irreversible lung damage and sometimes death results when the disease is not diagnosed and treated in early stages. A long-term implication of the disease is shortness of breath which requires the farmer to take frequent rest periods and severely limits the amount of work that can be accomplish. Inhaling these less noxious dusts decreases lung capacity and also causes some people to be more susceptible to respiratory infections such as pneumonia. Smoking of tobacco products has been reported to hasten the damage. To reduce the risk of respiratory problems from dusts, a farmer should store only dry grain and dry, well-cured forages and hay.
Mold develops in moist or wet grain, forages, hay and many other moist or stale organic materials.
To reduce dust exposure, a farmer should keep animal areas as clean and dust-free as possible. Stale dust and feed accumulations attract and absorb moisture from the air in the barn, creating an environment for mold and other microorganisms to grow. Safety Precautions Disposable dust masks or a respirator with a replaceable cartridge designed to filter dusts ensures an adequate supply of clean air for the farmer. Change the mask or cartridge frequently for the greatest protection. Test the atmosphere if possible.
