Molds are simple, microscopic organisms found virtually everywhere. Molds can be found on plants, foods, dry leaves and other living material. Mold growths can often be seen in the form of discoloration, ranging in color from white to orange and from green to brown to black.
Health problems from exposure to mold can vary greatly depending on the person and the amount of mold in the home. The type of health symptoms that may occur include coughing, wheezing, nasal and throat conditions. People with asthma or allergies who are sensitive to mold may notice their asthma or allergy symptoms worsen.
Any damp conditions in a home can lead to the growth of mold, if not quickly and properly eliminated. These damp conditions can be caused by floods, leaky pipes, or excessive moisture in the home. The Minnesota Department of Health has extensive information about mold, it's health effects and ways to control it.
