Fish Cleaning Recommendations

Mercury and PFOS cannot be removed through cooking or cleaning -- they get into the flesh of the fish. However, you can reduce the amount of other contaminants like PCBs by removing fat when you clean and cook fish.

Remove the skin, cut away the fat along the back, trim off the belly fat, cut away the fatty area along the side of the fish

Remember the following tips when eating fish:


Eat smaller fish.


Eat more panfish (sunfish, crappies) and fewer predator fish (walleyes, northern pike, lake trout).


Trim skin and fat, especially belly fat. Also, eat fewer fatty fish such as carp, catfish, and lake trout. PCBs build up in fish fat.
