PHYSICIANS FOR SOCIAL RESPONSIBILITY, accessed 21 March 2005 through their http://www.mercuryaction.org website Recent studies surveying contaminant levels in farmed and wild-caught salmon have shown that, on average, farmed salmon contain substantially higher concentrations of a variety of persistent organic contaminants such as PCBs, dioxins, and pesticides. These studies indicate that wild salmon, being generally lower in toxic contaminants, is a healthier choice for consumers. However, closer inspection reveals that contaminant levels in individual fish can vary widely across wild and farmed salmon of various species and from various geographic regions, so the issue is not black and white.

With new studies showing PCBs, dioxin, and pesticides in salmon and mercury in canned tuna, consumers who find themselves struggling to figure out what’s safe to eat will find some species of fish are high in contaminants, while others are generally low. The reason is usually diet — some fish eat smaller fish, but other fish eat veggies and tiny organisms.
[ True to the pattern, ignorant Americans may again be duped by short-sighted politicians under the sway of large corporations which aim to hide the unsustainability of our energy consumption as long as possible. While recent U.S. government claims suggest that drilling for oil in the Alaskan National Wildlife Refuge will yield “up to” 1.4 billion barrels of oil, this is at best a stopgap measure: the U.S. consumes 20 million barrels a day; hence one way to quantify the net effect of the proposed destructive drilling is to think of it as a 50-day appeasement of our oil-greedy appetites […]
