Exposure to Mold Infestation Is a Proven and
Serious Health Threat to Residents and Workers
by Phillip Fry
Many property owners,
landlords, employers, and mold victim relatives in Canada, the
USA, and worldwide often question or minimize the proven
and serious health threat arising from exposure to elevated
levels of indoor mold infestation, according to Phillip Fry,
Certified Mold Inspector, Certified Mold Remediator, and author of the book
Mold Health Guide.
Mold’s Harmful Effects
“All molds have the potential to cause health effects. Molds
can produce allergens that can trigger allergic reactions or
even asthma attacks in people allergic to mold. Others are
known to produce potent toxins and/or irritants,” according to
the US Environmental Protection Agency (EPA).
A number of commonly found mold species are, in fact, toxic
mold, a description applied to any mold that produces
mycotoxins in its spores. Stachybotrys (black mold),
Aspergillus, and Penicillium are three of the most dangerous
and commonly found indoor toxic molds.
Mycotoxins are cytotoxic, meaning they have the capacity to
pass through the human cellular wall and disrupt certain
cellular processes – potentially causing serious health damage
to workers and customers.
Studies on animals and cell cultures in labs have found toxic
effects from various microbial agents, raising concerns about
whether these same agents growing in buildings can cause
illness in people, according to the 2004 mold health report
from the Institute of Medicine (U.S. Government’s National
Academy of Sciences).
Mold Health Symptoms
Fungi can cause health problems to both humans and animals by
several different biological mechanisms: infections, allergic
or hypersensitivity reactions, irritant reactions, or toxic
reactions---reported a 2004 University of Connecticut Health
Center report
If exposed to elevated levels of indoor mold, some or many
residents and workers can experience one or more of most
common, mold health symptoms: allergies, asthma, bleeding
lungs, breathing difficulties, cancer, central nervous system
problems, recurring colds, chronic coughing, coughing up with
blood, dandruff problems (chronic) that do not go away despite
use of anti-dandruff shampoos, dermatitis, skin rashes,
diarrhea, and/or;
Eye and vision problems, fatigue (chronic, excessive, or
continued) and/or general malaise, flu symptoms (chronic),
sudden hair loss, headaches, hemorrhagic pneumonitis, hives,
hypersensitivity pneumonitis, irritability, itching (of the
nose, mouth, eyes, throat, skin or any other area), kidney
failure, learning difficulties or mental dysfunction or
personality changes, memory loss or memory difficulties;
and/or
Open skin sores and lacerations, peripheral nervous system
effects, redness of the sclera (white of your eyes), runny nose
(rhinitis) or thick, green slime coming out of nose (from sinus
cavities), seizures, sinus congestion, sinus problems, and
chronic sinusitis, skin redness, sleep disorders, sneezing
fits, sore throat, tremors (shaking), verbal dysfunction
(trouble in speaking), vertigo (feelings of dizziness,
lightheadedness, faintness and unsteadiness), and vomiting.
Mold Health Studies
“Where is the proof?” ask skeptical moldy home sellers,
landlords, employers, and unaffected relatives of mold victims.
There is actually abundant evidence about the serious impact of
mycotoxins and mold exposure in human disease.
Medical studies in both the military and agricultural
environments have discovered that that significant health
problems can readily arise from the inhalation of elevated
levels of fungal spores and toxins by soldiers and farmers.
Laboratory studies in animals and at the cellular level provide
supporting evidence for direct toxicity of fungal spores and
mycotoxins in mammalian lungs (University of Connecticut Health
Center report in 2004).
As to asthma (one of the most common health consequences of
mold exposure), a health study by the Finnish Institute of
Occupational Health links adult-onset asthma to workplace mold
exposure---
“The present (health study) results estimated that the
percentage of adult-onset asthma attributable to workplace mold
exposure to indoor molds and development of asthma in
adulthood. Our findings suggest that indoor mold problems
constitute an important occupational health hazard.”
The Finnish workplace mold study estimated that the percentage
of adult-onset asthma attributable to workplace mold exposure
to be 35% (Reported in Environmental Health Perspectives, May,
2002).
A European Community respiratory health survey in 2002 reported
that asthma patients experience more significant asthma
symptoms after they become sensitized to molds such as
Alternaria and Cladosporium species, and to dust mites.
Scientific evidence links mold and other factors related to
damp conditions in homes and buildings to asthma symptoms in
some people with the chronic asthma, as well as to coughing,
wheezing, and upper respiratory tract symptoms in otherwise
healthy people, stated the Institute of Medicine report.
“We were able to find sufficient evidence that certain
respiratory problems, including symptoms in asthmatics who are
sensitive to mold, are associated with exposure to mold and
damp conditions. Excessive dampness influences whether mold, as
well as bacteria, dust mites and other such agents, are present
and thrive indoors,” reported the Institute of Medicine in its
mold health report on May 25, 2004.
“In addition, the wetness may cause chemicals and particles to
be released from building materials. A rare ailment known as
hypersensitivity pneumonitis also was associated with indoor
mold exposure in susceptible people,” reported the Institute of
Medicine.
A 1994 Harvard University School of Public Health study of 10,
000 homes in the United States and Canada found that half had
conditions of water damage and mold, which was associated in
the study with a 50 to 100% increase in respiratory problems
for the residents of water and mold damaged homes.
Dr. David Sherris of the Mayo Clinic conducted (1999) a study
of 210 patients with chronic sinus infections and found that
most had allergic fungal sinusitis. The prevailing medical
opinion had been [prior to the Mayo Clinic study] that mold
accounted for only 6 to 7% of all chronic sinusitis. The Mayo
Clinic Proceedings reported on Sept. 13, 1999 that---
“Researchers have found that chronic sinusitis, a condition
that affects about 37 million people in the United States, is
apparently caused by an immune response to fungus (mold).”
The Centers for Disease Control (CDC) found an apparent link,
announced in 1997, between mold contamination in the homes and
cases of infant pulmonary hemorrhage.
The American Academy for Pediatrics (AAP) Committee on
Environmental Health released a statement (April 6, 1998)
concerning the toxic effects of indoor molds and acute
idiopathic pulmonary hemorrhage in infants.
The AAP recommended that until more information is available on
the cause of this condition, infants under one year of age
should not be exposed to chronically moldy, water-damaged
environments.
The AAP also recommended that pediatricians inquire about mold
and water damage in the home when treating infants with
pulmonary hemorrhage, and that when mold is present in a
patient’s home, that pediatricians should encourage parents to
try to find and eliminate sources of moisture.
At the University of Texas MD Anderson Cancer Center,
approximately 15-20% of patients with leukemia die of fungal
leukemia caused most frequently by the species Aspergillus.
In patients with leukemia who have undergone allogenic bone
marrow transplantation or allogenic hematopoietic stem cell
transplantation, 15-30% of deaths are caused by refractory
fungal infections such as Aspergillus, one of the most
dangerous indoor molds.
In recent years, comparative risk studies performed by EPA and
its Science Advisory Board (SAB) have consistently ranked
indoor air pollution among the top five environmental risks to
public health.
Ninety four percent (94%) of all respiratory ailments are
caused by polluted air according to the American Medical
Association, which also reported that one-third of the U.S.A.
national health bill is for causes directly attributable to
indoor air pollution.
Suggestions
“Any person at risk from mold should not be in an area that is
likely to be contaminated with mold. If you or your family
members have health problems after exposure to mold, contact
your doctor or other health care provider,” advises the Centers
for Disease Control.
Residents and workers often differ significantly (from
co-residents and co-workers) in their sensitivity and reaction
to mold exposure. Even the smell of mold can make some
residents and workers sick.
Consequently, there are no federal standards or
recommendations, (e.g. Occupational Safety and Health
Administration, National Institute of Occupational Safety and
Health, EPA and the Centers for Disease Control) for airborne
concentrations of mold or mold spores in either the home or the
workplace.
Thus, if one or a few residents, employees, or customers
experience one or more possible mold health symptoms, the
property owner, landlord or employer should still inspect and
mold test the residential or work premises for the health
protection of both the mold-sensitive residents and employees,
as well as others who may ultimately be harmed from
time-cumulative mold exposure.
Homes and workplaces should be carefully and thoroughly mold
inspected and mold tested all around by a Certified Mold
Inspector, Environmental Hygienist, or an Industrial Hygienist
if there are: (1) significant amounts of visible mold; (2)
serious water leaks, flooding problems, or high indoor
humidity; and (3) residents, employees, or business customers
[such as hotel guests] report experiencing one or more possible
mold health symptoms.
