Do environmental fish consumption advisories change how often you eat fish caught in your area?
The Wisconsin Department of Natural Resources has released updated fish consumption advisories for the Wisconsin River. These changes are based on recent evaluations of how per- and polyfluoroalkyl substances (PFAS) impact human health.
Why it matters
Updated guidance ensures that anglers and residents have the most current information to minimize exposure to harmful chemicals. These revisions are essential for managing health risks associated with the consumption of locally caught fish.
Official guidelines now restrict consumption of bluegill and perch near the Rhinelander Dam to one meal per month. A total do not eat advisory is now in effect for walleye harvested between Plover and Wisconsin Rapids.

The details
Toxicologists perform rigorous testing on various fish species to identify the levels of contaminants present in the waterway. The state has integrated this latest data with its existing 60-year record of tracking mercury and PCB levels to form comprehensive safety recommendations.
Timeline
The Department of Natural Resources has researched PFAS for the last 20 years.
Data collection for mercury and PCBs has been ongoing for 60 years.
State experts have focused specifically on PFAS monitoring for the last six years.
Deeper Dive
The Wisconsin Department of Natural Resources update follows the federal benchmarks established in the EPA's PFAS Strategic Roadmap. These state-level revisions align with and extend the regulatory focus set by the federal government's broader efforts to mitigate PFAS exposure.
Anglers should verify the updated consumption limits for specific segments of the Wisconsin River before fishing. These changes require a shift in routine for those who rely on local catches for their primary source of protein.
