ALLERGIES TO MOULD

There are many types of moulds in our environment. Allergic individuals are often allergic to moulds in the environment including seasonal leaf moulds (alternaria and cladosporium) as well as moulds that can be indoors (e.g. aspergillus). Mould grows in indoor and outdoor areas that are warm, dark and/or moist. Molds reproduce and grow by sending tiny spores into the air. Inhaled spores cause allergy and asthma symptoms.

ENVIRONMENTAL CONTROL

• Mould sensitivity can be identified by skin testing. Once this allergy has been detected, an attempt should be made to decrease or eliminate exposure to the mould.

• Allergy and asthma symptoms may improve over time if the environmental control changes are made. Many of the changes are for the entire home. The bedroom is the most important, because the bedroom is where people usually spend 1/3 to 1/2 of their time.

Control OF MOULD ALLERGENS

• In the bathroom - use an exhaust fan or open a window to remove moisture after showering. Wipe down the damp surfaces after showering. Wash bathrooms with a mould-preventing or mold-killing solution at least once a month.

• In the kitchen - use an exhaust fan to remove water vapor when cooking. Discard spoiled foods immediately. Empty the garbage daily. Empty water pans below self-defrosting refrigerators frequently.

• Remove mouldy stored items.

• Vent the clothes dryer outside.

• Remove leaves, clippings and compost from around your house.

  The person with a mould allergy should avoid cutting grass and raking leaves or wear a face mask for these activities.

Keep the indoor moisture low. The ideal humidity level is 30-40%. Use an air conditioner or dehumidifier in warm climates to decrease the humidity. Clean the dehumidifier regularly.Humidifiers and vaporizers are not recommended because they will increase humidity in the room and create a favorable environment for mould growth. If you must use a humidifier, clean it daily to prevent mould growth.
