Not all tuna is alike….

A new study may prompt hand wringing among you tuna poke and sushi lovers. When it comes to pollutant levels, researchers now say where your tuna was caught matters.

In a first-of-its-kind global study, scientists from Scripps Institution of Oceanography at the University of California, San Diego analyzed 117 yellowfin tuna taken from 12 locations worldwide, measuring the contaminant levels of each. They found yellowfin tuna caught closer to more industrialized locations off North America and Europe can carry 36 times more pollutants — including pesticides, flame retardants and polychlorinated biphenyls (PCBs) — than the same species caught in more remote locations, like in the West Pacific Ocean.

As unregulated fishing collapses tuna stocks elsewhere and global demand for tuna grows, the value of the fish here continues to climb. One Pacific bluefin recently sold in Japan for $1.76 million, and over the past four years, the cost of licenses to fish tuna in this region shot from $400 per day to $6,000. High prices and healthy stocks are a huge magnet for pirate fishers who flock to this part of the Pacific.
