Canned Tuna
Canned tuna, especially canned light tuna, is one of the most popular types of fish for many Canadians. The fish used in canned tuna products are generally younger and smaller and have significantly less mercury than fresh or frozen tuna, so that most Canadians don't need to be concerned about consuming canned tuna.
However, for those who consume large amounts of canned albacore tuna, there is some potential for exposure to higher levels of mercury than is considered acceptable.
Because of this, Health Canada has issued advice for children and some women on the consumption of canned albacore tuna. The advice does not apply to canned light tuna, nor does it apply to Canadians outside of the specified groups.
Canned albacore tuna is also often called canned white tuna, but it is not the same as canned light tuna. Canned light tuna contains other species of tuna such as skipjack, yellowfin, and tongol, which are relatively low in mercury. Canned light tuna also tends to be lower in cost relative to albacore tuna.

Þessi túnfiskur sem ég er með er skipjack tuna sem virðist vera í lagi, lítur út fyrir að það séu bara White tuna sem eru svona slæmir
Svo hérna má sjá hversu mikið mercury er í þessu
http://www.hc-sc.gc.ca/fn-an/pubs/mercu ... p#table4.5 Mean [MeHg] (μg/g)
Tuna, albacore, canned 0.36
Tuna, skipjack, canned 0.06
Svo skv. þessu er 6 sinnum minna mercury í skipjack tuna heldur en albacore tuna og þessi ráð frá FDA eiga við albacore (White) tuna. Svo það ætti að vera í lagi að borða 12 dollur af þessu (6*2) skv. FDA og þarmeð er ég innan marka
edit:
Ég fann þetta:
http://www.gotmercury.org/article.php?list=type&type=75Fann ekki skipjack, en fann annan með sama innihald og skv því má ég borða 40oz eða um 1130gr af þessu á viku sem er tæplega 8 dollur
edit 2.
FDA gefur upp gildið 0.144 á skipjack
http://www.fda.gov/food/foodsafety/prod ... 115644.htmSamt alveg skárra en albacore, en maður ætti þá kannski ekki að borða meira en 6 á viku
