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. Visit healthoregon.org/fishadv for additional advisories and to learn more about fish and shellfish cleaning guidelines that reduce your exposure to PCBs and other fat-soluble contaminants.

* Vulnerable population includes children under age 6, women of childbearing age and people with thyroid or immune system problems. “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.
