During the past several years, there have been a number of instances in which workers exposed to moldy wood chips have experienced respiratory health problems.
In most cases these health problems have been associated with inhalation of high numbers of fungal spores that can become deposited in the lungs.
Workers around chip piles in chipping mills or at pulp ing operations where chips are unloaded and stored are at the greatest risk of exposure.
The most common respiratory disease associated with wood-product workers is organic dust toxic syndrome.
Hypersensitivity pneumonitis is less common and may contribute to subsequent health problems.
Benign mucous membrane irritation or allergies may also occur.
Organic particles that contribute to respiratory problems include actinomycete spores, fungal spores, endotoxins, mycotoxins, and certain wood dusts.
It is likely that the occurrence of high levels of fungal spores is site specific and depends on the fungi present, type and origin of wood, environmental conditions, and handling or storing practices.
