Inhalation anthrax can occur when a person inhales spores that are in the air (aerosolized) during the industrial processing of contaminated materials, such as wool, hides, or hair. Chickens have evolved in such a way that they have innate immune protection against anthrax because their body temperature is too high for anthrax to survive.
