ORIGINAL: Big Les Well - there is a actually debate on this -as some sources say that the type of mercury in Tuna is not harmful However, mercury builds up so the bigger the fish the more mercury. The stuff used for cans is not the big Tuna fish at all, its much younger fish with much lower levels. Also its likely to be the product of several fishing areas - and we know that certain fish stocks are more prone to mercury contamination than others. Personally i would like to see the study done on european tuna - as the study that highlighted mercury was done in the US, which gets its Tuna from a different place to Europe, and I was told that US tuna cans tend to be based on the larger fish - because thats what sells over there, whereas in Europe we have the smaller fishes. Current guidelines for pregnant women are no more than 2 cans per week - for saftey. The thing with mercury is that it builds up slowly and we really dont know how long it would take to get a toxic level in a human from eating canned tuna - hence the conservative recommendations (lawsuit anyone), it may well be that people dont on average live long enough for it have an effect. Or that most people dont eat the amount of tuna required for long enough - and so on. In essence - we know that mercury is found in Tuna, we know that mercury can build up and get toxic, we know that mercury is transmitted to the foetus, and well apart from that - ist pretty much conjecture as we really dont know yet - Thats my reading of the situation As with anything you pay your money and take your choice. Personally i havent changed a thing about how much tuna I eat.
