I believe that domestic farmed catfish is safe to eat. Publix always has very fresh quality filets
and we enjoy Catfish Meuniere regularly (from The Best of Cooks Illustrated):
1/2 C flour
4 filets, 5-6 oz. each, PAT DRY
2 T oil
2 T butter
salt and pepper to taste
Browned Butter Sauce:
4 T butter
1 T ch. parsley
1 1/2 T lemon juice
Heat dinner plates in 200 degree oven.
Season both sides of fish with salt and pepper. Let stand until glistening, about 5 minutes. Coat with flour, shake off excess.
Heat 1 T oil on High, add 1 T butter. When foam subsides, place 2 filets, skin side up, in pan, reduce heat to med-hi, cook until edges are opaque and bottom is browned, 3 min.
Use two spatulas to flip filets and cook 2 min. more. Place filets on dinner plate in oven.
Wipe out skillet, cook two more filets same way, (1 T oil, 1 T butter). Place on dinner plate in oven to keep warm.
Browned Butter Sauce:
Wipe out skillet, heat butter until brown and nutty, 1-1 1/2 min. Add lemon juice to butter sauce, Salt and Pepper to taste, sprinkle fish with ch. parsley and spoon sauce over fish.
Enjoy!
