imported tuna has levels of mercury higher than the US federal limit. Libby Quaid reports:According to the Associated Press
Defenders of Wildlife found the highest levels of mercury in tuna from Ecuador and Mexico — countries known for setting nets where they see dolphins to catch large tuna swimming below.The group’s analysis revealed some daunting results:
"They tend to catch larger, more mature fish, which tend to have higher levels, being at the top of the food chain," said Bob Irvin, the group's senior vice president for conservation.
The group is a longtime advocate of dolphin-safe tuna.
The group had a laboratory test 164 cans of tuna labeled as being from Ecuador, Mexico, Costa Rica, Thailand, Malaysia, the Philippines and the United States. Tests were done by New Age/Landmark laboratory, a Benton Harbor, Mich., company that has been used by the federal government.
Average mercury content of U.S. tuna was generally lower than imported tuna.For more information on mercury contamination check out this previous post: Fishing for the Truth
Tuna from Asia had the lowest average levels of mercury.
Tuna from Latin America had the highest mercury levels, with some exceeding the government limit of 1.0 parts per million.
The lab found higher levels of mercury even in light tuna, which the Food and Drug Administration considers to be low in mercury.
