Tuna tops in mercury exposure for fish eaters

Consumption of tuna, the most commonly eaten fish in the United States, accounts for one-third of mercury exposure from eating seafood, a new study shows.

The study is in this month's issue of the journal Environmental Research, and shows that mercury content varies widely depending on the variety of fish. In all, 51 varieties of seafood are ranked based on mercury content.

Salmon, catfish and flounder have low levels while bluefin tuna and swordfish are among the varieties that have the highest levels. Shellfish and crustaceans such as clams and crabs were listed with low mercury levels, according to the study.

But the National Fisheries Institute's registered dietitian Jennifer McGuire says a study that looks only at mercury levels in seafood undermines the nutritional value of fish as a whole. Fish and other seafood are rich in omega-3 fatty acids and other nutrients that are good for both the heart and brain. Making healthy choices isn't that hard.

What about all the pollutants they don't test for?

The seas are just one big cauldron of toxic waste.

They should learn to grow meat in a lab instead.

I was suffering from mercury poisoning 2 months ago. I was consuming canned tuna and tuna sashimi like crazy.

Suffered extreme fatigue, insomnia and loss of appetite. I had to struggle to keep my weights up when working out and my workouts lasted 2 hours instead of my original 45 minutes due to very slow recovery.

I love seafood and fish but it seems like everything is farm raised out of China, Taiwan, or some other country that doesn't have the regulations of the FDA. Have you seen some of the tilapia farm videos floating around the internet? I just don't trust it... I won't even buy it unless it's wild... Atlantic Cod has been the easiest for me to find.

this could be a dumb question. but how much tuna does one have to eat to get poisoning? cause they're on sale at cvs for 49 cents a can and i just bought a shitload! lol

good question. should we worry about a miniscule amount? afterall, usnic acid is toxic, but its in some supplements.

The wild tuna has just as much mercury content then the farm raised tuna if not considerably more, methyl mercury bioaccumulates in small organisms then biomagnifies in bigger fish (ie. tuna eats small organisms, so the mercury works it way up the food chain). Tuna is not a small fish, which would explain it's higher content of mercury. Too bad though considering how good and cheap it is!

Canned Tuna fah life!!!!

interesting site, lets you plug in the type of fish and then calculates how much you cqan eat on a weekly basis before you risk mercury exposure

full disclosure: it is a pro-fishing site but still interesting

conversely, this site which is an environmental group says I can only take in 1 can per 9 days vs the above which says I can take in 32cans in 7days at a weight of 205lbs

I eat only 1 can a day of albacore tuna 5oz. 5 to 6 days a week. according to that second site that you posted there would be tons of people being poisoned with mercury being hauled off to the hospital. Thats gotta be some kind of mistake.

People get sick all the time with various symptoms. It just don't get linked to the real culprit.

Never had an issue with this, but often when I diet I tend to binge on certain foods for awhile and could see how this can be dangerous.
