These fish are fed unnatural diets and are contaminated with chemicals, antibiotics, pesticides, and other known carcinogens. They live in very crowded conditions which results in these fish having 30 times the number of sea lice than wild salmon. (Doesn’t that sound appetizing?) Farmed salmon are fed chemicals to make their meat that reddish pink color that should occur naturally but doesn’t because of the diet of chicken litter that they are fed.
Also, due to their diet, they have less of the healthy omega-3 that we think we are getting when we consume fish. Studies have also shown that farmed salmon contain high levels of PCB’s, mercury, and cancer causing dioxins. Avoid farmed salmon and buy it canned or look for labels in your market that state the fish you are buying is wild sockeye salmon.
