How to prepare fish from Devil's Swamp, Devil's Swamp Lake, and Bayou Baton Rouge
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.
