Answer 1

PCBs build up in fish and animal fat, and therefore proper cooking methods can help reduce your exposure:

Before cooking, remove the skin, fat (found along the back, sides and belly), internal organs, tomalley of lobster and the mustard of crabs, where toxins are likely to accumulate.

When cooking, be sure to let the fat drain away and avoid or reduce fish drippings.

Serve less fried fish; frying seals in chemical pollutants that might be in the fish's fat, while grilling or broiling allows fat to drain away.

For smoked fish, it is best to fillet the fish and remove the skin before the fish is smoked.
