dc.description.abstractThe presence in EU waters of invasive tetrodotoxin (TTX) -harbouring puffer fishes has been receiving increasingly attention due to potential new threats posed by this potent neurotoxin. The present study investigates the occurrence of tetrodotoxin, saxitoxin (STX), and their analogues in two native puffer fish species from the NE Atlantic. High TTX content was detected by LC-MS/MS in several tissues of the Guinean puffer Sphoeroides marmoratus from Madeira Island (Portugal), reaching concentrations as high as 15 mg TTX kg(-1) in the digestive tract of a male specimen and 7.4 mg TTX kg(-1) in gonads of a female specimen. Several TTX analogues were also detected, including the 4-epi-TTX, 4,9-Anhydro-TTX, 5- 11- deoxyTTX and 6,11-dideoxyTTX. Although at low levels, STX was detected in liver of the Oceanic puffer Lagocephalus lagocephalus. Trace levels of decarbamoylsaxitoxin (dcSTX) were also observed in L. lagocephalus. This study reports the presence of TTX and STX in native fish from EU waters, highlighting the need for a proper understating of the origin, distribution and fate of these toxins in NE Atlantic.
