84%, according to the Biodiversity Research Institute in Maine, of fish have hazardous levels of mercury, posing a health risk for people who eat some fish more than once a month.
The UN is facilitating an effort to Reduce mercury pollution at a conference this week in Geneva, where international delegates may agree to a treaty backed by the United States.
Eating fish is the primary means by which people are poisoned by mercury. Tuna & swordfish contain the most mercury of all, which permanently damages the brain and kidneys. Mercury pollution is global; no country alone or subset can rid its food supply of this contamination.
