'Do Not Eat' Warning: MDH Flags These MN Lakes For Toxic Fish

ST. PAUL, MN — The Minnesota Department of Health has updated its "do not eat" fish consumption guidance after finding elevated levels of PFAS, also known as harmful "forever chemicals," in fish from lakes, rivers, and ponds across 10 counties.

Officials are now warning anglers and families to avoid eating certain fish caught in parts of the Twin Cities metro and Greater Minnesota, while loosening restrictions in some areas like Lake Superior.

According to the new guidance, fish that no one should eat include:

• All species of fish caught in the Minnesota River Valley ponds and Long Meadow Lake (Hennepin County).
• Bass caught in Mooney Lake (Hennepin County).
• Walleye caught in George Lake (Martin County).
• Yellow perch and common carp caught in Otter Lake, McCuen Creek, Bear Creek, and the south fork of the Crow River (McLeod and Carver counties).

"Our fish consumption guidance can help anglers and their families make informed choices about which fish to eat and how often," said Angela Preimesberger, MDH’s fish consumption guidance program lead, in a news release.

"Following the guidance enables you to reduce your exposure to contaminants while still enjoying the many benefits of eating fish, which is an important part of a healthy, well-balanced diet."

The MDH said its fish consumption guidance is based on:

• Where you caught the fish. Some waterbodies have lower levels of PFAS and other contaminants than others.
• Who you are. Some people are more sensitive than others to negative health effects from exposure to PFAS. The most sensitive groups include people who are or could become pregnant, those who are breastfeeding or plan to breastfeed, and children under age 15.
• The species of fish. The maximum number of servings recommended per week or month may vary among fish species caught in the same waterbody.

Fish consumption guidance will be updated as new scientific information becomes available, so officials say to check the DNR’s LakeFinder or MDH’s Fish Consumption Guidance webpage before you eat fish caught in Minnesota.
