Mercury is not outlawed. Thimerosol is still widely used a preservative in

To make this fishing related it has been found that high mercury levels in
some fish is actually a naturally occurring phenomena, not a pollution
issue. Samples of Swordfish caught early last century were tested and
contained very high mercury content. Because they are long lived predators
they tend to concentrate mercury (among other things) over their entire
lifetime. Interesting
