Environmental Health Service receives a number of requests for information and assistance concerning the mold in the home, workplace or schools. We have developed this webpage as a source of information to assist the community.

Environmental Health Services does not provide mold testing, evaluate specific mold problems, or provide consulting services.

Molds can cause allergic reactions, fungal infections, and other health effects. Allergic and other illnesses can be treated by getting rid of the mold exposure. Your doctor may also prescribe medication to control symptoms.

Center for Healthy Communities

New to CDPH's YouTube Channel – The Center for Healthy Communities (CHC) of the California Department of Public Health (CDPH) recently released an 11-minute public health video on indoor dampness and mold, providing science-based advice aimed at county and city housing code enforcers. The video was produced by a microbiologist and an epidemiologist from the Indoor Air Quality Program in the Department's Environmental Health Laboratory (EHL) in Richmond.

This video is designed for code enforcement officers and anyone interested in what the current science tells us about dampness and mold in buildings.

Watch here and learn:

·         The indicators of dampness and mold in buildings that scientific studies have linked to health effects.

·         The underlying cause of all mold problems in buildings.

·         Why you should be skeptical about making and interpreting mold measurements.  

·         The important public health benefits of enforcing for mold and dampness in housing.
