For those who like to look at scientific papers and draw conclusions look at the bar charts for PCB levels in the Hites paper linked by "the chemist". Compare those levels to the levels found in wild Puget Sound chinook in the paper linked below. The contaminate levels are as high and in resident chinook much higher than the worst farmed salmon. It is all in the fat, even though Atlantic salmon contain the most fat of all a belly strip from a Puget Sound Chinook is not something people of child bearing age should eat.
