Health Effects of Mold Exposure
The CDC and EPA recognize that mold exposure can cause: nasal and sinus congestion, respiratory irritation, coughing and wheezing, eye irritation, skin irritation, and aggravation of asthma symptoms. For most healthy adults, mold exposure causes relatively mild, reversible symptoms. Sensitive individuals experience more significant effects.
Who Is Most At Risk
People with elevated mold sensitivity include: individuals with asthma or other respiratory conditions, those with allergies (especially to mold), children and the elderly, and people with compromised immune systems from illness or medications. For immunocompromised individuals, exposure to certain mold species can cause serious systemic infections.
The Black Mold Question
Stachybotrys chartarum, commonly called black mold, receives significant media attention. While it does produce mycotoxins under certain conditions, the scientific evidence linking household black mold to severe or chronic illness in otherwise healthy people is less clear than popular reporting suggests. Any mold present in significant quantities in a home should be remediated regardless of species.
When to Take Action
If household members are experiencing unexplained respiratory symptoms, headaches, fatigue, or worsening asthma, a mold inspection is warranted. If visible mold occupies more than 10 square feet, professional remediation is recommended by the EPA. Any mold in HVAC systems requires professional remediation to prevent distribution throughout the home.
Frequently Asked Questions
What symptoms does mold cause?
Common mold exposure symptoms include nasal congestion, coughing, wheezing, eye irritation, throat irritation, and skin irritation. In people with mold allergies, reactions can be more severe. In those with asthma, mold is a significant trigger.
Is all black mold toxic?
Not all black-colored mold is Stachybotrys chartarum, and not all Stachybotrys produces significant toxin levels in all conditions. Mold should be remediated based on its presence and extent, not solely on its color. Professional identification determines the actual species involved.
When should I see a doctor about mold exposure?
If you experience persistent respiratory symptoms, unexplained headaches, fatigue, or worsening of known conditions that correlate with time spent in a specific building, consult a physician. Mention your potential mold exposure so they can evaluate whether mold-related illness is a possible factor.
