What is the Food and Drug Administration (FDA) tolerance level for PCBs in fish?
The FDA tolerance (action) level for PCBs in commercial fish currently is two parts per million (2 ppm). The FDA has established tolerance levels for PCBs in foodstuffs, including fish, in interstate commerce. The FDA limits are used determine whether or not the food is safe to consume over an extended period of time; they do not include advice on limiting the number of meals of particular fish. The levels of PCBs found in trout stocked from state hatcheries are many times less than the FDA tolerance levels for PCBs in fish.
