Mercury Testing & Updating Tribal Walley Consumption Advice

Purpose

GLIFWC will determine mercury levels in walleye, lake trout, whitefish, cisco, and siscowet from Lake Superior and walleye from inland lakes. Test results for selected fish species and areas in Lake Superior will be compared with data from previous testing. Results from inland waters will be used to update tribal and lake specific GIS maps and consumption advice aimed at reducing health risks associated with consuming mercury contaminated walleye.

Objective

GLIFWC will determine mercury levels in walleye, lake trout, whitefish, cisco, and siscowet from Lake Superior and walleye from inland lakes. Test results for selected fish species and areas in Lake Superior will be compared with data from previous testing. Results from inland waters will be used to update tribal and lake specific GIS maps and consumption advice aimed at reducing health risks associated with consuming mercury contaminated walleye. Indigenous communities rely on fish as a source of subsistence. Therefore, monitoring mercury in fish flesh in harvested waters is imperative.
