Mold (fungi) are present everywhere. There are over 100,000 species of mold with at least 1,000 common to the U.S. Black Mold (Stachybotrys) is most likely to grow where there is water or dampness - such as in bathrooms and basements - and has been associated with health effects in people. 

Many molds appear black but are not Stachybotrys. For example, the black mold commonly found between bathroom tiles is not toxic. Stachybotrys can be positively identified by trained professionals through a microscopic exam.

DANGERS OF BLACK MOLD

When mold is disturbed, spores can be released into the air. Exposure can occur if people inhale these spores, directly handle moldy materials, or accidentally ingest it. Mold can also produce chemicals called Mycotoxins. Mycotoxins may cause illness in people who are sensitive to them or if they are exposed to large amounts in the air. As the indoor air level of Stachybotrys increases, the higher the chance of health affects such as:

​

Allergic Rhinitis (Cold-Like Symptoms) • Dermatitis (Rashes), Sinusitis, Conjunctivitis, and Aggravation of Asthma. Some related symptoms are more general - such as inability to concentrate and fatigue. In cases of prolonged or severe exposure, or cases exacerbated by an allergic reaction, more extreme symptoms can appear including nausea, vomiting, and bleeding in the lungs and nose.
