Tuna Served in Public Schools Contains Excessive Mercury

Canned albacore tuna purchased by US schools contains more mercury than what government officials have reported, raising the risks for some tuna-loving kids, according to a new study from a coalition of advocacy groups. Children who eat two medium servings of albacore, or white, tuna per week could be exposed to as much as six times the dose that federal guidelines consider safe, according to the report prepared for the Mercury Policy Project. It is the first study to test the mercury content of tuna brands purchased by schools.
