Michigan’s health department and natural resource agency is warning hunters to not eat deer taken at a northern Michigan marsh because of forever chemical contaminants in the meat.

Both the Michigan Department of Natural Resources and the Michigan Department of Health & Human Services say the venison can be harmful if consumed.

According to fox2detroit, animals that live around Clark's Marsh in Iosco County were exposed to per- and polyfluorinated substances, which are commonly called PFAS, and the contaminants have been found in their livers and muscle tissue. A 2021 report found PFAS levels in Michigan deer in the northern counties.

PFAS include manmade chemicals used in consumer products such as nonstick pans, stain-resistant clothing, and firefighting foam. These chemicals do not break down and have become an increasingly worrisome emergence in the environment. The bonds that make up PFAS are among the strongest in the world. One researcher said the key to permanently destroying them is exposing them to temperatures of 30,000 degrees Celsius. In addition to wildlife and fish, the PFAS have also been detected in people, resulting in negative health impacts including liver damage and reduced fertility.
