Consumption Advisory

Because of pollution, many lakes and rivers in Minnesota are under a fish consumption advisory from the State Department of Health.

Statewide safe fish eating guidelines are based on mercury and PCB levels measured in fish throughout Minnesota and on levels of mercury found in commercial fish. Not all waters in Minnesota have been tested for contaminants in fish. But the Safe Eating Guidelines can be used for both tested and untested waters.

The guidelines are particularly protective for children and women of child-bearing age. These groups should not eat walleyes larger than 20 inches, northern pike longer than 30 inches, and muskellunge.
