Answer:

ConsumerLab's tests of popular brands of canned tuna and salmon found that all five brands of albacore ("white" tuna) were contaminated with mercury to such an extent that you should limit intake to no more than one serving per week. Brands of skipjack tuna contained less mercury, although, one had a mercury level suggesting consumption not more than twice a week.

Yellowfin tunas contained the least mercury among the tunas; however, one had a fairly high amount of arsenic (as did most albacore tunas), suggesting that its use also be limited.

So, while it is safe for you to continue to eat albacore tuna once a week, there are some better tuna alternatives. 

Before you settle back to eating albacore tuna, or any tuna, consider canned salmon -- particularly pink salmon, which is mild-flavored and light-colored, like albacore tuna. It is also more "heart healthy" than most tunas because pink salmon tends to provide greater amounts of the omega-3 fatty acids EPA and DHA than albacore tuna. Furthermore, the pink salmon brand we tested had the lowest amount of mercury and second lowest amount of arsenic of any of the tested canned tunas and salmons.

Although it may not appeal to your tastes, if you really want to boost your omega-3 intake, try sockeye ("red") salmon. The three sockeye salmons that we tested all provided very high amounts of omega-3's and low amounts of mercury and arsenic.

I eat sashimi(raw fish) twice a week, which includes salmon, tuna, and yellowtail,only. No canned fish. Should I be concerned about the amounts of mercury consumed as in canned fish?

Hi Philip - Yes, you should be concerned. Mercury is not a problem of canning, but of the fish itself -- particularly any type of tuna.

How decent are those mercury test kits you can buy online? Can I test my tuna with them? For example, I saw the Osumex HMT Mercury Kit on Amazon.com. It claims you can test food with it. I just don't know who they are and how much to trust their claims.
If such test kits are poor, is there a way I could get my tuna (and other fish) tested?

We were also hooked on canned white albacore tuna. So we tried canned Kirkland Wild Alaskan Pink Salmon from Costco. Terrific. Mild taste and easy to mix. Give it a whirl!

Thank you, Julius17195. Would you say that it would taste terrific even for someone who just DOES NOT LIKE salmon at all? I'm willing to try it, but I really dislike salmon.

Yes, the Kirkland canned salmon tastes very much like the albacore tuna. I'm on the same page as you are and I dislike fish in general. I always liked the albacore tuna though, until I learned it wasn't exactly safe to eat.
