Tetrodotoxins occurrence in non-traditional vectors of the north atlantic waters (Portuguese maritime territory, and morocco coast)
Tetrodotoxin (TTX) is a potent alkaloid typically from tropical ecosystems, but in the last decade its presence has been more pronounced in the temperate waters of the Atlantic. In its last scientific opinion, the European Food Safety Authority (EFSA) stressed the need for data regarding TTX prevale...
