Good link Dogfish. Thanks!

I'm a little confused by your comment. Do you think Pacific farmed Atlantics are significantly worse than to eat than wild salmon?

"Atlantic salmon contained higher PCB concentrations (means, 28-38 ng/g) than farmed coho or chinook salmon, and levels in these latter species were similar to those in wild counterparts (means, 2.8-13.7 ng/g)"

It seems odd you'd leave out the very next sentence

"PCB levels in Atlantic salmon flesh were, nevertheless, 53-71-fold less than the level of concern for human consumption of fish, i.e., 2000 ng/g as established by Health Canada and the U.S. Food and Drug Administration (US−FDA)"

Here's the full version for those not in the ivory tower of academia.
