I did do a quick google search on Russian salmon, and it appears if it's been processed in China, that's where the iffy factor comes up. Obviously, the Russian salmon I was eating came direct from the source and was good. But salmon, just like beef, should say where it's been handled, right? Isn't that part of U.S. food labeling laws?
Maybe it's only the source, not the processing. Hmmm...
Well, in theory, it should be good.
