Muhlenberg County Health Department Mold Information
What are molds and where are they found?
Molds are fungi found both indoors and out, almost everywhere in the environment. They can grow all year long and grow best in warm, damp and humid conditions. Molds spread by making spores that can survive harsh environmental conditions that normally do not support mold growth.
In the home, mold is almost always present in the air and grows best in damp areas with high humidity levels, like bathrooms and basements. While there are perhaps thousands of species of mold, most common indoor molds include Cladosporium, Penicillium, Alternaria and Aspergillus.
How can I test for mold in my home?
Generally, it is not necessary to identify the species of mold growing in a residence, and CDC does not recommend routine sampling for molds. Current evidence indicates that allergies are the type of diseases most often associated with molds. Since the reaction of individuals can vary greatly either because of the person’s susceptibility or type and amount of mold present, sampling and culturing are not reliable in determining your health risk. If you are susceptible to mold and mold is seen or smelled, there is a potential health risk; therefore, no matter what type of mold is present, you should arrange for its removal. Furthermore, reliable sampling for mold can be expensive, and standards for judging what is and what is not an acceptable or tolerable quantity of mold have not been established.
