How has the U.S. federal government determined safe levels of PCBs in foods? “The FDA has set residue limits for PCBs in various foods to protect from harmful health effects. FDA required limits include 0.2 parts of PCBs per million parts (ppm) in infant and junior foods, 0.3 ppm in eggs, 1.5 ppm in milk and other dairy products (fat basis), 2 ppm in fish and shellfish (edible portions), and 3 ppm in poultry and red meat (fat basis).” Two ppm in fish is equivalent to 2,000 ppb (parts-per-billion) in fish. The fish oil products in question today contain less as a percentage by weight than is allowed even in baby food, and are taken in far smaller amounts by total weight per serving than whole fish. Yet these fish oils are now being targeted for added label warnings that they are known by the state of California to contain toxins with the false implication that these minute dietary amounts are proved to be harmful and should be avoided at all costs.

What are the alternatives? Apparently eating actual fish won’t do; they would be consumed at far larger serving weights and naturally contain far more PCBs than a serving of natural fish oil. Yes, some fish oils are highly purified, which is what the lawyers argue as a reasonable alternative to the natural oils. Yet there are legitimate critics who argue against chemically processing and refining natural food products such as this, even for reasons of purity. And some of the oils most likely to have accumulated PCBs are from long-lived fish which are higher in the ocean food chain and have been long valued as health foods with strong evidence of enhancing human health.

If we force all foods to either have disproportionally scary warnings or be processed out of their natural states, pushing only the least natural products as the “best” choices, this has serious implications for the nature of our food supply and how it impacts our nutritional status. We have seen degenerative disease rates soar as the amount of refined foods in the diet increases, and natural food advocates have long argued that we return to unrefined whole foods in order to naturally maintain health. This current fish oil scare is capable of needlessly frightening people away from taking safe healthy fish oils that could improve their health. That would be the real crime.
