The Wisconsin Department of Natural Resources has updated fish consumption advisories for the Wisconsin River, impacting anglers across the state. These guidelines reflect new findings regarding the health effects of chemical contaminants.
Why it matters
Updating these advisories is necessary to reflect current research into how persistent chemicals impact health, helping residents make informed decisions about their dietary safety.
These advisories are informed by toxicological testing and species-specific PFAS monitoring conducted over the last six years. This builds upon 20 years of PFAS research and 60 years of data on mercury and PCB contamination levels in local fish populations.
