Definition of Mold

Mold: A very large group of microscopic fungi that live on plant or animal matter. Most are filamentous organisms and produce spores that can be air-, water-, or insect-borne. A common trigger for allergies.

For people who are sensitive to molds, exposure can cause symptoms such as nasal stuffiness, eye irritation, or wheezing. People with serious allergies to molds may have more severe reactions. Severe reactions may occur among workers exposed to large amounts of molds in occupational settings, such as farmers working around moldy hay. Severe reactions may include fever and shortness of breath. People with chronic illnesses, such as obstructive lung disease, may develop mold infections in their lungs.

People allergic to molds should avoid areas that are likely to have mold, such as compost piles, cut grass, and wooded areas. Mold growth in the home can be slowed by keeping humidity levels below 50% and ventilating showers and cooking areas. Mold growth can be removed with commercial products or a weak bleach solution (1 cup of bleach in 1 gallon of water). In situations where mold exposure is unavoidable, sensitive people should wear a tight-fitting face mask.
