Oceana is the largest international organization focused solely on ocean conservation, and they've created awareness with grocers regarding mercury and seafood. Some larger grocers have opted to post warnings about mercury in seafood on Oceana's Green List. Those on the Red List do not.
It is suggested that those who are mercury/heavy metal poisoned eliminate all seafood consumption, and those with recent dental work eliminate seafood consumption until the site is completely healed.
