I agree the study probably draws the wrong conclusion as to the safety of farmed salmon -- and by the way, the study also found levels of PCBs above EPA safety levels in free-swimming salmon -- but before you find a conspiracy under every rock, it might be worth noting that Santerre now works for the salmon farming industry. Also, the Journal of Science is the most respected academic journal in America and typically does not publish BS. Furthermore, I never saw any concentrations reported in parts per trillion, and I read the report in Science.
