Mercury and Tuna
Mercury toxicity
Nearly all fish contain trace amounts of methyl mercury, some more than others. In areas where there is industrial mercury pollution, mercury levels in the fish can be quite elevated. In general, however, methyl mercury levels for most fish are very low. However, certain species of very large tuna, typically sold as fresh steaks or sushi, can contain methyl mercury levels in excess of the Food and Drug Administration, (FDA) 1 part per million (ppm) limit. Canned tuna, composed of smaller species of tuna such as skipjack and albacore, has much lower levels of methyl mercury, averaging only about 0.17 ppm. Click here for more information. Experts theorize that albacore, because it is a short-lived species, would tend to have less mercury than bigger, longer-lived tuna such as Blue-fin or Big-eye Tuna. And, by the same theory, the younger and smaller the albacore, the better. For the tuna fan, perhaps the best approach is to buy quality, not quantity, a strategy that the current canned tuna wave encourages . San Francisco Chronicle, Wednesday, August 21, 2002 Dave Salmon and Albacore Results We sent can samples of both our Gourmet Albacore Fillets and Wild King Chinook Salmon to The National Food Laboratory, Inc. in August, 2002. The salmon samples came back with results of less than one half of one tenth part per million (ppm). The Albacore samples returned results were of less than one third of one part per million (very trace amounts). This translates into negligible amounts Nearly non-detectable. These results are so far below the FDA, 1 part per million limit, that it would take many cans consumed at one time to amount to this limit. http://davedraper.com/mercury-in-tuna.html -- Diva ************* The Best Man for the Job is a Woman |
