Didn't know fish oil supplements have Pcb  

PCB = polychlorinated biphenyls. Used in the plastics industry amongst others. If you look hard enough you will discover that virtually every foodstuff will do you harm. But you have to balance the advantages with the disadvantages. I would think that you are pretty safe with your fish oil supplements the PCB content is at trace levels. Let us know if you turn into the Terminator though. We'll find you a State to govern! LOL.

Isn't that one of the chemicals that is in plastics that they have proven that is not safe for humans to consume from it? I could be wrong about that. However, it seems like almost everything that we consume is dangerous to us in one way or another, so I take all of these warnings that we are hearing these days for a grain of salt. These days, I will listen to these warnings but I have come to accept the fact that I am most likely going to die from cancer, so I don't need to worry about it too much.
