The environmental group, Defenders of Wildlife, says that canned tuna
from Costa Rica, Ecuador and Mexico can contain mercury levels 30
percent to 50 percent higher than the federal limit. It is believed
that larger fish have more mercury because they are older and have been
exposed to the substance longer.
Tuna caught in Thailand and the United States have less mercury because
the fishing is usually done in “dolphin safe” conditions. This type of
fishing is more likely to net smaller tuna with less mercury.
The canners in Mexico and Ecuador usually buy from fishers who drop
their nets near schools of dolphins. This usually assures they get the
larger / older Tuna. These tuna usually have the higher levels of
Mercury.
The lowest levels of Tuna Came from US canners including Bumble Bee,
Chicken of the Sea, and Starkist tuna. At the bottom of the list were
four varieties of Trader Joe's brand tuna from Thailand with levels as
low as .012 parts per million. Calmex light brand topped thelist at at
1.4 parts per million.
Ingestion of high levels of mercury can be dangerous. Mercury has been
linked to heart and kidney damage in adults and to learning disabilities
and developmental disorders in children.
So what is a safe amount to eat? The Food and Drug Administration (FDA)
says consumers can eat up to 12 ounces (about 2 meals) of tuna a week.
Pregnant women and children should only eat fish and shellfish with
lower concentrations of mercury.
The Defender’s of Wildlife recommend that this be cut in half. They say
that adults should only consume 6 ounces per week and children half of
that.
