MADISON, Wis. (WMTV) - Before you take that fresh catch home for dinner, make sure you’re aware of new fish consumption advice in Dane and Rock Counties.

Wisconsin’s Departments of Natural Resources and Health Services put out new guidance Wednesday on eating fish caught in Yahara Chain Waters.

This applies to fish species with elevated levels of PFAS, harmful chemicals in water. One of the most widely produces PFAS called PFOS builds up the most in fish.

“PFAS or per/poly-fluoroalkyl substances are a large group of man-made chemicals that have been widely used since the 1950′s. When they are spilled or improperly disposed of they can easily travel through the environment, do not easily break down and often build up in fish tissue,” said Nathan Klockzo, DHS Site Evaluation Program Coordinator.

The DNR now recommends you only eat one meal per month of Walleye, Largemouth Bass, Crappie and Northern Pike and one meal per week of Pumpkinseed, Yellow Perch, and Bluegill.

Authorities say exposure to PFAS is something to take seriously.

“PFAS can stay in your body for years. High levels of PFAS have been connected to increased cholesterol levels, decreased immune response and decreased fertility, though that research is still emerging,” said Klockzo.

The advisory applies to fish caught in the following lakes and waterways:

  • Lake Monona
  • Lake Waubesa
  • Lake Kegnosa
  • Upper and Lower Mud Lakes
  • Starkweather Creek
  • Wingra Creek
  • The Yahara River, downstream to where it meets the Rock River

These advisories are not in place at Lake Mendota or Lake Wingra.

The DNR is working closely with Dane and Rock County Health Departments to develop new signage and outreach techniques to educate fishermen and women who frequent these waterways.
