Farmer’s Lung
What is farmer’s lung and what is their risk?
Farmer’s Lung is an allergic disease usually induced by breathing the dust from stale hay. People can get Farmer’s Lung by breathing in dust containing the spores of special, heat-tolerating bacteria or moulds often found on moldy crops. Spores from two types of bacteria, “Micropolyspora faeni” and “Thermoactinomyces vulgaris”, and certain types of moulds called “Aspergillus” are the major causes of Farmer’s Lung. The spores that cause Farmer’s Lung are not infectious. Farmer’s Lung develops in two steps, as other allergic reactions do.
In some areas, blood tests have shown that 20 to 40 percent of farm workers have antibodies that react with antigens responsible for Farmer’s Lung. The degree of risk depends on the amount of dust that has collected in the person’s lungs. The condition is associated with intense or repeated exposure to inhaled biologic dusts. The symptoms are serious, and once the allergic reaction begins, the person will always have the potential for symptoms when they’re exposed to hay mould.
