How does PFAS affect fish in our lakes and rivers?

Fish across the state are tested for PFAS annually, and the Michigan Department of Health and Human Services releases Eat Safe Fish Guides every Spring.

As new guidelines are set as a result of elevated levels of PFOS, Michigan is releasing those advisories outside of the annual Eat Safe Fish Guides update.

In Wayne County, the state has issued warnings about the fish in Lake St. Clair and the Huron River due to PFAS contamination. In order to protect our health, we must limit our consumption of contaminated fish, or eliminate fish from certain sources to protect ourselves from PFAS.
