Chemical form and distribution of mercury and selenium in canned tuna

Journal of Applied Toxicology, 1982
AbstractThe content, chemical form and distribution of mercury and selenium were determined for several samples of canned tuna. Samples represented albacore, bluefin, skipjack and yellowfin species, and were packed in either water or vegetable oil. Recently‐processed samples (less than one year old) and much older samples (8–29 years old) were examined.

Canning of tuna in oil

1971
This paper provides the experimental details of canning of tuna in oil. The species utilized in the experiments were the skipjack (Katsuwonus pelamis), yellowfin tuna (Neothunnus macropterus) and bigeye tuna Parathunnus obesus mebachi) ranging it weight from 2.5-82 kg. The method worked out is applicable to all species of different size grades.

Mercury in canned tuna: The importance of selenium

Environmental Toxicology and Chemistry, 2009
To the Editor: The recent article by Gerstenberger et al. [1], reported the mercury (Hg) concentrations, but did not report the selenium (Se) contents of the tuna. Since methylmercury is, by biochemical definition, a highly specific irreversible inhibitor of Se-dependent enzymes [2], it is necessary to measure both Hg and Se to accurately assess risks ...
