  • Stachybotrys Mould is also known as black toxic mould. Often found in long term water damaged buildings (WDB). 
  • Stachybotrys mould produces mycotoxins: trichothecene, roridin E & verrucarin. Mycotoxins can impact the gut microbiome by reducing the beneficial gut bacteria and impact the intestinal lining/barrier, resulting in leaks into the blood stream, resulting in a variety of adverse health effects.


Health Effects


  • Most biotoxin/mycotoxin-related health effects range from fatigue, weakness, memory problems, disorientation, headaches, vertigo, muscle and joint pains, light sensitivities, shortness of breath, chronic abdominal pain and high amounts of static shock.
  • Exacerbation of asthma has been associated with the following fungal species: Penicillium, Aspergillus, Cladosporium, and Alternaria. Stachybotrys mycotoxins will accumulate on contaminated materials, and therefore, it is best to remove/dispose of the contaminated materials.
  • Exposure to Stachybotrys and their mycotoxins often showed symptoms of skin “rash, especially in areas subject to perspiration, dermatitis, pain and inflammation of the mucous membranes of the mouth and throat, conjunctivitis, a burning sensation of the eyes and nasal passages, tightness of the chest, cough, bloody rhinitis, fever, headache, and fatigue” (Nelson, 2001).
