I also was listening to a radio programme (where they were interviewing a university researcher,) about seals getting uterine cancer from eating salmon where the concentration of toxins multiplied into the fish fat. It has really put me off salmon. Only an occasional treat from now on.

I think you need to look for fish farmed in spring water or a clean river. I would imagine lakes not as good as a river. The kineisiologist said that the seas are accumulating toxins, so older fish are worse than younger, shallow water worse than deep sea fish.

We eat organic meat whenever possible. WHat ever the animal eats affects the quality of meat produced.In England we have lots of grass fed meat which is healthier than feed lot cattle common to USA.

Our food bills are probably nearly twice as high as they were. The price of good health I guess.
