What are the actual health risks of mold growth in buildings?
• Infection. They can begin to grow inside the body. Mold (fungal) infections are rare except among people who are immune-compromised. • Allergies. For those people who are allergic to a particular mold, the health effects can be quite serious. With high exposure levels, it is possible for mold allergies to develop. Aggravation of asthma and sinusitis can also occur, and has aspects in common with allergic reactions. • Toxic effects. Many molds produce fungal poisons (mycotoxins) as a defense mechanism against other micro-organisms. Some of these are toxic to humans if there is a sufficient dose. Whether mold growth in buildings provides a sufficient dose to cause serious human health effects is hotly debated among scientists. The US EPA says, “When moisture problems occur and mold growth results, building occupants may begin to report odors and a variety of health problems, such as headaches, breathing difficulties, skin irritation, allergic reactions, and aggravation of asthma sympto
