The entire Pacific ocean–including Alaskan waters are highly radioactive causa Fukishima–so avoid anything coming from there including sea salt…the soviet union dumped barrels of nuclear waste into the North sea for over 50 yrs–they have been leaking and splitting open=Fukishima waste is now in the Atlantic–if u must have fish oil, use oils from the scandanavian fjord area–avoid capsules–get. oil in a glass bottle. I like Carlsen brand.
