Advisories are designed to help you gain the health benefits of eating fish and shellfish while protecting you and your family from contaminants sometimes found in seafood.
Consumption guidelines provide recommendations for when you should limit or avoid eating certain fish or shellfish to reduce your exposure to chemicals like mercury, PCBs and other contaminants. The key is to make smart choices and choose fish and shellfish that are low in contaminants. In general, younger, smaller fish have fewer contaminants.

All resident fish; avoid eating carp, bass and catfish
“Resident” fish spend their entire lives within a certain territory, and do not migrate.“Migratory” fish such as salmon, steelhead, shad and lamprey, spend most of their lives at sea, and contain less localized contaminants. In general, smaller, younger fish have fewer contaminants.
Follow these fish cleaning guidelines to reduce your exposure to PCBs and other fat-soluble contaminants.
What is a meal?
A meal is about the size and thickness of your hand, or 1 ounce of uncooked fish for every 20 pounds of body weight.
Mercury and PCBs accumulate in our bodies over time and are passed on to developing fetuses through the placenta. Children’s brains go through extraordinary development in the womb and during the first six years of life. Mercury and PCBs can interfere with normal brain development and cause lifelong learning disabilities. PCBs can also cause cancer in children and adults.
