With the wet weather and exceptionally wet seasons in Northern Illinois, mold is a constant concern for local residents.
There are up to 100,000 different types of mold. There are no ‘standards’ for mold exposure. You will need to talk to your physician regarding any medical concerns. 
?Keep humidity levels at 40-60% at all times; you can purchase a relative humidity gauge at most hardware stores. 

? The Winnebago County Health Dept. does not perform mold inspections. However, a listing of private contractors who can perform these tests can be found in the yellow pages of the phone book under “mold”.
?Mold and its clean up is the responsibility of the property owner. WCHD will take complaints based on a “foreign substance”, but is not able to confirm whether it is actually mold.
The source of the moisture must be identified and repaired to prevent future problems.  Hard, non-porous surfaces such as walls & floors can be cleaned with a warm water/non-ammonia based detergent.
