过敏性肺炎的一种类型农民肺，由于农民吸入耐热的放线菌，它由发霉的干草中繁殖生长。鸟尘(爱鸟病)和空调中的霉也引起类似的问题。田野中标准捆包，质量好，就很少发生种此病。
One form of hypersensitivity pneumonitis is known as farmer's lung because the farmer inhales thermophilic actinomycetes in moldy hay that set off the reaction. Bird dust (bird fancier's disease) and molds in air conditioners may produce similar problems. The bales in this field near Sterling are of good quality and less likely to produce this disease.
