Levels of polychlorinated biphenyls (PCB) and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/F) in fillets of farmed Southern Bluefin Tuna (Thunnus maccoyii).

Southern Bluefin Tuna (SBT) (Thunnus maccoyii) is the only farmed tuna species in the southern hemisphere, with production centred offshore of Port Lincoln, South Australia. SBT farming is a quota-based fishery where farmers fatten wild-caught stock for subsequent sale as fresh-chilled or frozen product, mainly to Japanese markets. Fillets from wild-caught and farmed SBT were analysed and the concentration of polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are reported for the first time.

Dioxins, PCBs, metals, metalloids, pesticides and antimicrobial residues in wild and farmed Australian southern bluefin tuna (Thunnus maccoyii).

Data concerning the concentration of dioxins (PCDD/PCDFs), polychlorinated biphenyls (PCBs), metals, metalloids, pesticides and antimicrobials residues are reported for the edible portion of Australian wild and farmed southern bluefin tuna (Thunnus maccoyii). In 2004 wild caught (n=5) and farmed (n=26) southern bluefin tuna (SBT) were collected. The mean concentration of total mercury on a fresh weight (fw) basis was 0.
