How to prepare fish from Lower Columbia
Some contaminants build up in fat and skin, so cleaning and cooking can lower your exposure. Others — mercury and PFAS — are in the muscle itself and trimming does nothing.
PCBs
- Skin the fish — most of the contaminant sits in the fat just under the skin.
- Trim the fatty areas away: the belly flap, the top of the back, and the dark lateral line down each side.
- Cook on a rack — grill, broil, or bake — so the fat drips off the fillet.
- Throw the drippings out; don't use them for soup, sauce, or chowder.
- Choose smaller, younger fish — they've had less time to build it up.
