Tinned tuna mercury levels vary by species
Mercury levels in seafood vary significantly depending on the species. While large predatory fish such as shark, swordfish, and marlin often contain higher concentrations of mercury due to their size and lifespan, most tinned tuna sold in Australia consists of smaller species like skipjack and yellowfin.
Because these smaller species are generally younger, they typically contain much lower levels of mercury than the larger fish often used for fresh tuna steaks. Food Standards Australia New Zealand (FSANZ) utilizes international safety guidelines to determine mercury consumption limits. Additionally, it is noted that tuna is always cooked before being packaged in cans.
