What are the health effects of mold?

Everyone is exposed to some amount of mold every day. Not everyone is mold sensitive. Continual exposure to active mold spores in the home, workplace or outdoors can, over time, cause or worsen health effects.

What are the health symptoms of mold exposure?

According to a 2004 Institutes of Medicine Report, Damp Indoor Spaces and Health, sufficient evidence exists only to link mold exposure to upper respiratory (nose and throat) symptoms, coughing, wheezing and asthma symptoms among sensitized individuals.

Molds produce allergens, irritants and, sometimes, toxins that may cause adverse health reactions. The types and severity of symptoms depend on the types of mold present, extent of the mold exposure and an individual's existing allergies to mold.

What if someone in my household is sensitive to mold?

Consult a health care provider to learn if the symptoms may be related to mold allergies. Keep anyone who is known to be sensitive to mold away from the exposure. You may need to find temporary living arrangements for them if the mold problem is large enough.

How do I clean up mold?

Clean-up of small areas of mold can be safely done by an individual home owner, who takes the proper precautions. It is important to take precautions to limit your exposure to mold and mold spores.

The following are basic steps recommended by the EPA:

  • Scrub mold off hard surfaces with detergent and water, and dry completely.
  • Fix plumbing leaks and other water problems as soon as possible. Dry all items completely.
  • Absorbent or porous materials, such as ceiling tiles and carpet, may have to be thrown away if they become moldy. Mold can grow on or fill in the empty spaces and crevices of porous materials, so the mold may be difficult or impossible to remove completely.
  • Avoid exposing yourself or others to mold.
  • Do not paint or caulk moldy surfaces. Clean up the mold and dry the surfaces before painting. Paint applied over moldy surfaces is likely to peel.
  • If you are unsure about how to clean an item, or if the item is expensive or of sentimental value, you may wish to consult a specialist. Look for specialists who are affiliated with professional organizations.

If you are using a strong cleaning solution, you should select gloves made from natural rubber, neoprene, nitrile, polyurethane, or PVC.
  • Wear goggles. Avoid getting mold or mold spores in your eyes.

What is toxic mold?

Some molds can produce toxins under certain circumstances, but this does not occur everywhere there is mold growth. Research on the presence, detection and effects of mold toxins is ongoing. One mold in particular, Stachybotrys atra (chartarum) has received a lot of attention.

The initial reports on the health affects of this mold have been revised by the Centers for Disease Control and Prevention. Fear of mold has been sensationalized in the news media and on many websites, and citizens need to be cautious when considering expensive testing and be informed about the kind of information that the testing will yield.

As a rule, mold testing in private homes when visible mold growth is present is not recommended by the Centers of Disease Control and Prevention nor the US Environmental Protection Agency.

It is stressed, however, that all mold, no matter the type, must be properly cleaned-up and moisture in the home must be controlled.

  • The key to mold control is moisture control.
  • If mold is a problem in your home, you should clean up the mold promptly and fix the water problem.
  • It is important to dry water-damaged areas and items within 24-48 hours to prevent mold growth.
