What is Mold Toxicity?

Mold is an example of a fungi that reproduce through the formation of spores. They may grow indoors or outdoors and thrive in environments that are warm, humid and damp. The most common places inside the house where they usually grow are bathrooms and shower stalls [2]. The spores of mold usually starts in places where there is excessive moisture such as leakages in pipes, roof plant pots or places where there recently was a flood. Building materials like cardboard, wood, ceiling tiles and paper products provide nutrients that support the growth of molds [1]. The five most common varieties of mold that can be seen inside the house are [3]:

  • Alternaria
  • Aspergillus
  • Cladosporium
  • Penicillium
  • Stachybotrys

Mold Toxicity

Molds that are known to produce mycotoxin are the type that is dangerous to human. People react to this chemical when they unknowingly touch, ingest or inhale them. One example of a mycotoxin is the aflatoxin which is one of the most potent carcinogen in the world. This chemical is present on the surface of the mold that forms on peanuts and other grains. Stachybotrys or “black mold” can possibly cause difficulty in breathing, bleeding in the lungs and other health problems [3].

Toxic Mold Symptoms

Exposure to toxic mold can bring about different signs and symptoms. Some of these are [1, 2, 3]:

Allergic reaction

The most common symptoms of exposure to toxic mold is allergic reaction. This may occur immediately or after a period of time following the exposure. An allergic reaction to toxic mold may cause wheezing, coughing, sneezing, redness of the eyes and runny nose [1, 2, 3].


The mycotoxin produced by Stachybotrys mold can irritate the airway when it is inhaled. This can trigger an asthma attack to those who have asthma [1, 2, 3].

Hypersensitivity pneumonitis

The Institute of Medicine have identified the link between the development of hypersensitivity pneumonitis and exposure to toxic mold. This rare disease is similar to a pneumonitis and develops in individuals who are susceptible to this immunologic condition [2].

Mold Toxicity Treatment

The focus of the management of exposure to toxic mold is to manage the symptoms that have developed and remove the accumulation of mold [1, 2, 3, 4].

Symptom management

Those who have developed an allergic reactions may be given antihistamines to reduce the intensity of the symptoms. Asthmatic individuals may use their medications to manage the asthmatic attack [1, 2, 3, 4].

Mold removal

Removal of the mold is the best way to manage the exposure to toxic mold. Commercial products are available to remove mold for hard surfaces. Personal protective equipment should be worn while cleaning to avoid the exposure to mold. Molds that grow under the carpet or behind the walls would need a professional to remove the growth in these places. Items that have become moldy should be removed from the living areas of the house [1, 2, 3, 4].
