Here are 5 things to know about Stachybotrys, which is commonly referred to as "black mold" or "toxic mold" due to it's mycotoxin production:
1. The mold is generally slimy, which makes it harder to sporulate (reproduce, or spread into the air) compared to other molds. When the Stachybotrys genus is discovered in air samples taken in a property, high spore counts can suggest that this is a longer term mold issue in the property.
2. Mycotoxin poisoning by this fungus is referred to as Stachybotryotoxicosis (Nelson, 2001).
3. The Stachybotrys fungus is most notably found within buildings which have sustained a long term flooding issue, or general water damage from broken piping, roof leaks etc.
4. According to the US Department of Health and Human Services, the most commonly reported symptoms related to airborne Stachybotrys exposure include: "allergic rhinitis (cold-like symptoms,) dermatitis (rashes,) sinusitis, conjunctivitis, and aggravation of asthma. Some related symptoms are more general, such as inability to concentrate and fatigue. Usually symptoms disappear after the contamination is removed." (FOH, 2017)
5. Exposure can be through ingestion, inhalation and skin exposure.
If you suspect you may be subjected to Stachybotrys in your property, it is advised to contact a professionally licensed microbial expert to properly assess the property.
