Molds are very small organisms found almost everywhere. They are common on plants, foods, dry leaves and other living material. Exposure to mold could cause health effects.
Health problems from being around mold can vary greatly. Symptoms could include coughing, wheezing, runny nose and sore throat. Individuals with respiratory conditions or sensitivities, like asthma, could notice more severe reactions.
Damp conditions in a home can also lead to mold growth if not quickly and properly eliminated. Floods, leaky pipes and excessive moisture provide the right conditions for mold growth. Mold growth usually looks like a stain, ranging in color from white to orange and from green to brown to black.
The Minnesota Department of Health has more information on mold, including its health effects and ways to control it.
Testing and inspection
Carefully look and smell for mold signs and odors. Focus on areas where there are signs of moisture or where moisture problems are suspected. The goal of your inspection is to locate the indoor mold growth and determine how to correct the moisture problem. You then can remove the contamination safely and effectively.
Dakota County Public Health and the state do not provide inspection or testing services.
We offer help by phone and email. We normally suggest that you investigate potential mold problems on your own first.
Homeowners can hire indoor air quality service providers to assist in investigating and removing mold. These professionals use special equipment to investigate potential issues.
Neither the state nor federal agencies license or certify mold investigators or remediators.
