I do not believe animals retain mercury forever. In humans, once the
dietary source of mercury is removed or stopped, mercury levels gradually
return to normal. Mercury levels in the hair remain high for an extended
period of time.
I haven't seen any literature on concentrating mercury by water removal,
but it sounds logical. I think tuna jerky processors are concerned about
increased mercury in the final product.

produces fish meal, fish oil and fish solubles from a variety of fish

mercury.

> I know that potentially mercury could pose a food safety hazard for
animal health as mercury is retained in the animals body and does not pass
through their system. Due to the removal of water during processing would
average mercury levels be increased in the fish meal, fish oil and fish
solubles?
