The Wisconsin Department of Natural Resources released a report Tuesday detailing the findings of PFAS in the liver of deer harvested and analyzed from the JCI/Tyco Fire Technology Center in Marinette, Wisconsin.
The DNR and Wisconsin Department of Health Services issued a ‘Do Not Eat’ advisory for the liver from deer harvested within 5 miles of the JCI/Tyco Fire Technology Center (FTC). This includes areas of Marinette, Peshtigo and surrounding communities. The FTC is located at 2700 Industrial Parkway, Marinette.
The DNR conducted a study on PFAS levels in deer from the JCI/Tyco Fire Technology Center in Marinette. Twenty deer were harvested and tested for PFAS levels in muscle, heart, and liver tissues.
PFAS levels in muscle and heart tissue were either very low or not detected. For those who eat venison from deer harvested within the five-mile advisory area, the muscle and heart of white-tailed deer are not likely to result in significant PFAS exposure, according to the DNR’s findings. Therefore, the DNR and DHS have not issued a PFAS-based consumption advisory for muscles or hearts of deer from this location.
However, significant PFAS levels were found in deer liver tissues. The liver filters chemicals from the blood, and some chemicals, like PFAS, can accumulate in the liver over time. These findings suggest that eating liver from deer in this area is likely to result in significant PFAS exposure. The Wisconsin DHS and DNR recommend people not eat liver harvested from deer within the advisory area. Further investigation of PFAS in deer from other locations is under consideration.
“We want to be clear that people should feel comfortable eating venison from deer they’ve harvested near this area," said Tami Ryan, DNR wildlife health section chief. "We just advise they do not consume the liver.”
Per- and polyfluoroalkyl substances (PFAS) are man-made chemicals used in industrial processes and manufactured products. PFAS don’t break down easily and can remain for a long time in the environment where people can be exposed to them. PFAS can accumulate in the human body slowly over time through repeat exposure. High levels of PFAS in the body are harmful to human health, especially to the health of pregnant women.
