Lipophilic toxins occurrence in non-traditional invertebrate vectors from North...
Silva, Marisa; Rodríguez, Inés; Barreiro, Aldo; Kaufmann, Manfred; Neto, Ana Isabel; Hassouani, Meryem; Sabour, Brahim; Alfonso, Amparo; Botana, Luis M.In the last decades, due to monitoring programs and strict legislation poisoning incidents occurrence provoked by ingestion of naturally contaminated marine organisms has decreased. However, climate change and an thropogenic interference contributed to the expansion and establishment of toxic alien species to more temperate ecosystems. In this work, the coasts of Madeira, São Miguel islands and the northwestern...

Tetrodotoxins occurrence in non-traditional vectors of the north atlantic water...
Silva, Marisa; Rodríguez, Inés; Barreiro, Aldo; Kaufmann, Manfred; Neto, Ana Isabel; Hassouani, Meryem; Sabour, Brahim; Alfonso, Amparo; Botana, Luis M.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 prevalence in European waters. To address EFSA’s concerns, benthic organisms such as mollusks, crustaceans, echinoderms a...

Silva, Marisa; Rey, Verónica; Barreiro, Aldo; Kaufmann, Manfred; Neto, Ana; Hassouani, Meryem; Sabour, Brahim; Botana, Ana; Botana, LuisParalytic shellfish toxins (PSTs) are potent alkaloids of microalgal and cyanobacterial origin, with worldwide distribution. Over the last 20 years, the number of poisoning incidents has declined as a result of the implementation of legislation and monitoring programs based on bivalves. In the summer of 2012 and 2013, we collected a total of 98 samples from 23 different species belonging to benthic and subtidal...
New invertebrate vectors of Okadaic acid from the North Atlantic Waters - Portu...
Silva, Marisa; Rodriguez, Inés; Barreiro, Aldo; Kaufmann, Manfred Josef; Neto, Ana Isabel; Hassouani, Meryem; Sabour, Brahim; Alfonso, AmparoOkadaic acid and its analogues are potent phosphatase inhibitors that cause Diarrheic Shellfish Poisoning (DSP) through the ingestion of contaminated shellfish by humans. This group of toxins is transmitted worldwide but the number of poisoning incidents has declined over the last 20 years due to legislation and monitoring programs that were implemented for bivalves. In the summer of 2012 and 2013, we collected a...
First report of Ciguatoxins in two starfish species: Ophidiaster ophidianus and...
Silva, Marisa; Rodriguez, Inés; Barreiro, Aldo; Kaufmann, Manfred Josef; Neto, Ana Isabel; Hassouani, Meryem; Sabour, Brahim; Alfonso, AmparoCiguatera fish poisoning (CFP) is a syndrome caused by the ingestion of fish contaminated with Ciguatoxins (CTXs). These phycotoxins are produced mainly by dinoflagellates that belong to the genus Gambierdiscus that are transformed in more toxic forms in predatory fish guts, and are more present in the Indo-Pacific and Caribbean areas. It is estimated that CFP causes per year more than 10,000 intoxications worl...
