Too late for moderation, in my opinion. We are all now loaded with toxins of every kind. Farmed salmon may not have mercury in it, but they are grey and died the pink of your choice from a color chart and fed a really noxious swill. (Even breathing is no longer a good idea.)
“Farmed fish, on average, showed a level of polychlorinated biphenyls, or PCBs, about seven times higher than that of wild fish. The average dioxin level in farm-raised salmon was 11 times higher than in wild salmon.
The key difference is what the fish eat—the same difference that prompted last year’s controversy over artificial coloration of farmed salmon. Many many sources: One
Farmed fish are fed a mixture whose creation relies heavily on catching fish such as small anchovies, then processing them into fish oil and fish meal. This concentrates contaminants that have scattered across the globe. PCBs, a family of chemical compounds used in industrial lubricants and coolants, were banned in this country in the 1970s but still are used overseas.
Wild salmon eat a variety of other fish, including tiny shrimp known as krill that give their flesh a reddish orange color. Farmed fish would be gray without artificial coloring.
“This is a product that does contain great beneficial nutrients, but it also contains PCBs at levels that are expected to cause cancer in the population,” said Jane Houlihan, an environmental engineer with the Environmental Working Group. “They know how to remove the PCBs from the feed and the fish.”
