| Extreme mold cases are possible without precautions. |
Although molds are a natural part of our environment, exposure to certain types of airborne mold spores can cause allergic reactions, asthma episodes and other respiratory problems. In addition, exposure to high spore levels can cause the development of an allergy to the mold. Health impacts from mold/mildew occur when individuals are exposed to large doses of mycotoxins, which are by-products produced from the molds. Adverse health effects from exposure to mycotoxins may differ from person to person. While some people may be highly sensitive to mycotoxins and experience adverse health effects, other people exposed to the same dosage of the mold will be unaffected. The mere presence of mold found indoors does not indicate a public health risk.
Certain types of mold are considered toxic and can cause serious health effects. These species include Stachybotrys chartarum, Aspergillus versicolor, A. flavus, A. fumigatus and Fusarium moniliforme. Stachybotyrs Chartarum is a greenish black mold that forms in environments with high moisture such as those that have water damage, water leaks, excessive humidity, condensation and flooding. The health effects of Stachybotyrs Chartarum range from short-term irritation to extremely serious illnesses. Stachybotrys chartarum can produce mycotoxins that can develop into an indoor air quality problem. Stachybotrys chartarum has the potential to cause symptoms such as coughing, wheezing, runny nose, irritated eyes or throat, skin rash or diarrhea.
Certain population groups have a greater health risk when exposed to mold. These people include infants and children, elderly, immune compromised patients, pregnant women and individuals with respiratory conditions. Pathogenic mold can cause serious health effects in persons with suppressed immune systems, those taking chemotherapy, or those with HIV/AIDS. Allergenic molds, normally not dangerous, can cause allergy or asthma symptoms.
