Residential real estate expert witness Steve Cohen writes this on mold:

Most types of mold that are routinely encountered are not hazardous to healthy individuals. However, studies have shown that too much exposure to mold may cause or worsen conditions such as asthma, hay fever, or other allergies. Common symptoms of overexposure are cough, congestions, runny nose, eye irritation and aggravation of asthma. In those who are more vulnerable, more serious health effects such as fevers and breathing problems can also occur. Some molds produce chemicals called mycotoxins. Mycotoxins may cause illness in people who have sensitivity to them.

According to the EPA, "A major concern associated with exposure to biological pollutants is allergic reactions, which range from rhinitis, nasal congestion, conjunctival inflammation, and urticaria to asthma". The most effective way to control mold is to control moisture. It is recommended that humidity levels be reduced to 30-60% to reduce the possibility of mold growth.
