The ocean currents head from Japan to the West Coast of the U.S so Is It Safe to Eat Salmon from the West Coast?

The Topp (Tagging of Pacific Pelagics) project has discovered that bluefin tuna once believed to live separate lives in Japanese and Californian waters may belong to a single population.
Before, this tuna would have been counted twice and we would have thought there are twice as many tuna as there are,said Prof O'Dor.
Not to worry, though: ...fish are so unlikely to be contaminated, that the US govt. won't even bother to test them, so all's well...
