I recently read an article about mercury in canned tuna. It singled out albacore as having especially high levels; the FDA recommends limiting it to one meal per week, 6 ounces. In the same article it says that the American Heart Association advises people to eat fish at least twice a week. I guess just not albacore. For those interested, below is a link to a fun online "Mercury calculator". You can choose a fish, enter in the amount of it you eat per week, and enter in your own body weight, and it will tell you if you're getting too much mercury. (I'm guessing this is just an estimate, though, because I read that, for a particular type of fish, the larger ones contain more mercury than the smaller ones.) http://gotmercury.org/ Now that I wrote this, I'm wondering if anyone is going to come out and say: "I happen to like mercury! Mercury is good. Savior it. Let it pool on your tongue in little beads that you can roll around in your mouth. Hell, on occassion I crack open a thermometer and slather that beautifully gleaming silver liquid all over my seafood! Oh man, that's heaven..."
