Mold in our Environment
The University of Louisiana Monroe takes the safety of our students, employees, and
community members seriously and strives to create a workplace free from recognized
hazards. Here is some general information from The Centers for Disease Control and
Prevention (CDC) and the US Environmental Protection Agency (EPA):
It is impossible to eliminate all mold and mold spores in the indoor environment.
Exposure to mold does not necessarily present a health problem. Generally, it is not
necessary to identify the species of mold growing in a residence, and CDC does not
recommend routine sampling for molds. Since the susceptibility of individuals can
vary greatly either because of the amount or type of mold, sampling and culturing
are not reliable in determining your health risk.
What are molds?
Molds are fungi that can be found both indoors and outdoors. No one knows how many
species of fungi exist but estimates range from tens of thousands to perhaps three
hundred thousand or more. Molds grow best in warm, damp, and humid conditions, and
spread and reproduce by making spores. Mold spores can survive harsh environmental
conditions, such as dry conditions, that do not support normal mold growth.
What are some of the common indoor molds?
- Cladosporium
- Penicillium
- Alternaria
- Aspergillus
How do molds affect people?
Some people are sensitive to molds. For these people, exposure to molds can lead to
symptoms such as stuffy nose, wheezing, and red or itchy eyes, or skin. Some people,
such as those with allergies to molds or with asthma, may have more intense reactions.
Severe reactions may occur among workers exposed to large amounts of molds in occupational
settings, such as farmers working around moldy hay. Severe reactions may include fever
and shortness of breath.
Where are molds found?
Molds are found in virtually every environment and can be detected, both indoors and
outdoors, year round. Mold growth is encouraged by warm and humid conditions. Outdoors
they can be found in shady, damp areas or places where leaves or other vegetation
is decomposing. Indoors they can be found where humidity levels are high, such as
basements or showers.
Mold growth can be removed from hard surfaces with commercial products, soap and water,
or a bleach solution of no more than 1 cup of household laundry bleach in 1 gallon
of water.
