Maybe one should get their Omega 3 oils from fish oil that is molecularly distilled, rather than from eating farm raised salmon? This report is rather disturbing to say the least.

Salmon Problems?: "The surprising results mean that farmed-raised salmon now on grocery shelves are the most PCB-contaminated protein source available to US consumers, if the groups findings are borne out by more comprehensive testing. On average the farmed salmon tested contained 16 times the PCBs found in wild Alaskan salmon, four times as much as in beef and 3.4 times as much PCBs as found in other seafood."

Here's what I use at a good price. Your health food store may also carry this, and if not, you can special order it. I usually get it for around $10/bottle. It's got a lemon/lime flavoring which is helpful when it comes to swallowing it. :) (It's really rather tasteless). I like to buy it in the health food store since it is refrigerated there. I take a cooler w/ice with me and transport it home that way. How they truck it to the store is a very good question - not sure I know the answer to that.
