Stachybotrys Molds and the Effect on Health
In the past decade, there has been a heightened alert about toxic molds
in homes, buildings and schools. The culprit seems to be Stachybotrys
mold, a fungus originally identified in Russia in the 1930’s. It
was discovered in horses and eventually farm workers, who were exposed
to hay or feed grain. The symptoms of contact included rash, dermatitis,
pain and inflammation of the mouth and throat, conjunctivitis, chest tightness,
cough, fever, headache and fatigue. Stachybotrys chartarum has resulted
in millions of dollars in litigation and has caused serious problems for
building managers and homeowners who must deal with remediation and human
issues of illness.
Although many questions
remain unanswered about the effects of Stachybotrys molds on individual
health, we have learned that one should not handle materials contaminated
with the mold. Research strongly indicates that environments infected
with Stachybotrys chartarum are unhealthy and can result in illness. Typically,
the younger the host, the more serious the health problem. The fact that
science has not determined if the symptoms are caused by an allergic reaction
to the mold, or by the mold itself, has no bearing on avoidance. Although
symptoms vary in each case, it is most important to determine the source
of the irritant; basic treatment involves removal of the cause.
Source of Stachybotrys Mold
The spores of the fungus are embedded in the soil and introduced into
homes and buildings that have been exposed to sustained flooding or water
damage from broken pipes, leaks in the roof, walls or floors, condensation,
etc. Wet conditions are necessary to initiate and maintain growth. It
is common for it to grow on the paper covering of gypsum wallboard; cellulose
based ceiling tiles, wallpaper, insulation and organic debris. There may
be little or no visible evidence of the mold, but nevertheless, its presence
can cause contamination through cracks or holes. Condensation due to inadequate
design or faults in the heating, ventilation or air conditioning systems
will encourage the development of the spores.
What to do?
Detection of Stachybotrys molds is usually carried out by visual inspection
or through air and surface sampling. If there are suspected areas of contamination,
removal of the fungus must follow recommended safety procedures for working
with toxic molds. If the areas are disturbed, such as when they are torn
down, the dust created can increase exposure to the fungus. Remediation
in large areas is similar to asbestos removal; however, unlike asbestos,
after removal of the fungus, the source of the contamination must be addressed.
Leaking pipes must be fixed, moisture trapped in mechanicals needs must
be flushed with a bleach mixture, and any materials harboring the spores
need to be removed and replaced.
Help and extensive information on Stachybotrys molds can be found in
local health departments, colleges and universities with agricultural
extension services, private consultants, and the internet. Do not attempt
identification or remediation without advice from a trained professional.
Whether you are living in a “sick building” where people
are experiencing symptoms of toxicity, or dealing with mold in your home,
the issue should be addressed immediately. The problem will not go away
by itself, nor will the symptoms abate over time. If you have any persistent
symptoms related to Stachybotrys mold, do not hesitate to see a physician.
