Potential Health Effects Associated with Inhalation Exposure to Molds and Mycotoxins
Allergic Reactions (e.g., rhinitis and dermatitis or skin rash); Asthma; Hypersensitivity Pneumonitis; Other Immunologic Effects Research on mold and health effects is ongoing. This list is not intended to be all-inclusive.
The health effects listed above are well documented in humans. Evidence for other health effects in humans is less substantial and is primarily based on case reports or occupational studies.
Some molds, such as Aspergillus versicolor and Stachybotrys atra (chartarum), are known to produce potent toxins under certain circumstances. Although some mycotoxins are well known to affect humans and have been shown to be responsible for human health effects, for many mycotoxins, little information is available, and in some cases research is ongoing. For example, some strains of Stachybotrys atra can produce one or more potent toxins. In addition, preliminary reports from an investigation of an outbreak of pulmonary hemorrhage in infants suggested an association between pulmonary hemorrhage and exposure to Stachybotrys chartarum.
Review of the evidence of this association at CDC resulted in an a published clarification stating that such an association was not established. Research on the possible causes of pulmonary hemorrhage in infants continues.
Consult the Centers for Disease Control and Prevention (CDC) for more information on pulmonary hemorrhage in infants. (See Resources list for CDC contact and other information.)
