EQRoy/Shutterstock Yellowfin tuna caught closer to more industrialized locations off North America and Europe can carry 36 times more pollutants than tuna caught in more remote locations, found a recent study from Scripps Institution of Oceanography at the University of California, San Diego. These pollutants include pesticides, flame retardants, and polychlorinated biphenyls (PCBs). Instead of ordering yellowfin tuna, opt for albacore or skipjack tuna, which contain lower levels of pollutants. If you’re going to have yellowfin, make sure it was fished from somewhere in the West Pacific Ocean rather than the northeast Pacific Ocean or the northeast Atlantic Ocean. Hungry?

Pacific Bluefin Tuna especially is threatened with extinction, but Atlantic Bluefin tuna is also endangered, according to International Union for Conservation of Nature’s Red List. Avoid bluefin tuna, and instead look for albacore tuna belly instead, which still has a rich flavor but is much more sustainable.
