Laboratory analysis revealed that all of the 148 tins of tuna tested were contaminated with methylmercury, a particularly dangerous form of mercury that accumulates in fish and poses serious health risks to humans. The analysis showed that 57% of the cans exceeded the strictest maximum mercury limi...
However, in Spain light tuna is mainly yellowfin and bigeye tuna, while in other countries it is mainly skipjack tuna. This study analyzed 36 cans of the most popular brands in Spain and examined the influence of the type of tuna, packaging medium (olive oil, sunflower seed oil, water or...
Solder used in the manufacture of cans is a recognised source of contamination of food by lead during canning. The presence of heavy metals, and particularly mercury, in the environment has been a matter of concern since their toxicity has been clearly documented (Uchida, Hirakawa & Inoue, ...
Effects of canning on total mercury, protein, lipid, and moisture content in troll-caught albacore tuna (Thunnus alalunga) Fifty-six cans containing meat from either the dorsal loin or the ventral flap of 10 troll-caught albacore tuna were tested for total mercury concentration... RS Rasmussen,...

However, other sources say that you would need to eat at leastthree cans of tunaa day for 6 months to risk mercury toxicity. The United States Food and Drug Administration recommends keeping the consumption of albacore (white) tuna to under 4 ounces per week and skipjack (light) tuna to ...

Tuna steak and albacore tuna were reported to have larger quantities of methylmercury than canned light tuna, which the advisory said is safe. The January 2011 issue of CONSUMER REPORTS (page 20) advised pregnant women to avoid all canned tuna entirely, and stated that although most cans of ...
positively correlated, but there was an interaction between Hg intake and genotype such that the intake–biomarker relationships differed among genotypes. Specifically, among avid fish consumers (i.e., those who ate six cans of tuna per week), there was an 8-fold difference in average hair Hg...
