Fish advisories are designed to help you gain the health benefits of eating fish while protecting you and your family from contaminants sometimes found in fish.
Fish consumption guidelines provide recommendations for when you should limit or avoid eating certain fish to reduce your exposure to chemicals like mercury, PCBs and other contaminants. The key is to make smart choices and choose fish that are low in contaminants. In general, younger, smaller fish have fewer contaminants.
NOTE: Not all of Oregon’s waters have been sampled for contaminants in fish. For more information about fish advisories in Oregon, or contaminants in fish and their health effects, call the Oregon Health Authority at 1-877-290-6767.

Contaminants and their health effects
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.
