I read about this report. 10 samples! That's supposed to be representative?

Two, I immediately want to know why farm-raised salmon would have higher PCB levels than wild salmon. PCBs increase in predatory fish because with each step up the food chain, the "food" has more contaminants in it. (Same goes for mercury.) So wild fish consuming wild food should have higher levels than farmed fish consuming feed.

NOW, in another thread I pointed out that farmed fish eat fish meal. So the first obvious thing to do is to test the fish meal for PCBs.

This whole scare junk is the result of improvement in analytical techniques...it wasn't too long ago these small amounts would have been undetectible.
