Fish advisories are warnings to the public from state health departments and federal agencies that eating certain fish poses a danger to health because of chemical contamination. They provide graphic public testimony to the risks chemical contamination poses to local and regional ecosystems. The Great Lakes region of the United States contains a disproportionate share of the nation’s fish advisories. While the states bordering the Great Lakes account for 27 percent of the nation’s people, they are home to 75 percent of the nation’s fish advisories and 72 percent of all of the nation’s fish advisories due to POPs contamination. Fully 100 percent of the Great Lakes waters and their connecting waters are under advisories.
