PCB's in seafood ?

Studies show there are more of PCBs in butter and brown gravy packets than in most types of seafood. Studies also show we eat much, much more PCB's in cattle, poultry, pork, and dairy than we do in seafood. 

"I’m not saying that we shouldn’t be concerned about PCBs in our food.  But I don’t think we should worry about seafood any more than we worry about contamination in beef, chicken, or pork.  Now pass the gravy." [1]
