Black Mold

Stachybotrys – The Black Mold Demystified

Since the 1993-1994 unusual outbreak of pulmonary hemorrhage (lung breeding) in infants in Cleveland, Ohio, that was then thought to be due to  exposure to Stachybotrys, the health effects associated with this mold have remained controversial. Frequently referred to as the Black Mold by the general public, Stachybotrys has probably caused more economic and psychological agony than ill-health. The mold has resulted in multimillion dollar remediations and litigations.

Stachybotrys was first associated with death of horses in Eastern Europe in the 1930s. Horses fed with hay contaminated with Stachybotrys were reported to surfer from a disease characherized by irritation of the mouth, throat, and nose; shock; dermal necrosis; a decrease in leukocytes; hemorrhage; nervous disorder; and death.

While Stachybotrys is so much feared the number of cases where it was the cause of ill-health or death are insignificant compared to some other toxigenic molds such as Aspergillus flavus or Aspergillus fumigatus. There are about 15 species of Stachybotrys but the most well known is Stachybotrys chartarum. Stachybotrys chartarum is sometimes erroneously referred to as pathogenic mold. When encountered in buildings it’s a serious problem for homeowners, building managers and remediation contractors who must deal with the human issues and remediation. The presence of a single spore in an air sample is enough for some professionals to declare the remediated building unfit for human occupancy. Currently there is no scientific evidence to support such a decision. Perhaps such decisions are driven by fear of liability, fear of being sued by someone who may later believe they were sick because the building was found to have a few spores of Stachybotrys when they occupied it. It’s time the scientific community demystified Stachybotrys, the black mold, for everyone’s peace of mind.

Black Mold Symptoms Explained

The phrase “black mold symptoms” is one of the most searched phrases regarding health effects of mold. The general public believes that black mold is dangerous. However, the term “black mold” does not refer to a specific type of mold. Similarly there are no symptoms specific to “black mold”. A number of molds that grow indoors may appear black. Generally all molds regardless of their color are potentially a health hazard if allowed to grow indoors.

Symptoms of Mold Exposure

The term “black mold symptoms” is rather misleading. People who are sensitive to molds, regardless of the color of the mold, may experience various symptoms such as nasal stuffiness, eye irritation, wheezing, or skin irritation. Those with serious allergies to molds, may have more severe reactions. Severe reactions may occur among workers exposed to large amounts of molds in occupational settings, such as farmers working around moldy hay, demolition workers tearing down a moldy building, and even people working near or in composting facilities. Severe reactions may include fever and shortness of breath. People with chronic lung illnesses, such as obstructive lung disease, may develop mold infections in their lungs.

These symptoms are not restricted to mold exposure. They could also be caused by other airborne polutants. Therefore, the fact that someone is experiencing these symptoms does not necessarily mean they are caused by mold exposure. It’s also important to remember there are no “black mold symptoms” and “black mold” could be any of the several types of molds that appear black.

Exposure limits to black mold

Many times we’re asked the exposure limits to black mold. Unlike other indoor pollutants, there are no exposure limits to mold. Exposure limits to mold would be difficult to set because human beings differ in their susceptibility to mold. Similarly, the molds themselves differ in their ability to cause health problems.

Molds may affect human beings in three different ways:

  • Allergenicity
  • Infection
  • Toxicity

As concerns common indoor molds the most likely effect is allergenicity. Very few fungi (molds and yeasts) are known to cause infection to healthy individuals. Toxicity is most likely to occur if one eats food contaminated with the fungal toxins. While toxicity is also possible through inhalation of spores or dust containing toxins, little is known about this possibility. 

Generally, elderly people, infants, sick people and other individuals with weak immune systems are at higher risk of suffering from mold exposure related diseases than healthy people.
