ABSTRACT: We have already shown the presence of guanidine neurotoxins in calcareous red algae and mussels collected in the São Sebastião channel (State of São Paulo, Brazil). It is known that these neurotoxins comprise more than 25 analogues such as tetrodotoxin (TTX) and derivatives plus the paralytic shellfish toxins (PST) found in a variety of marine, freshwater and amphibious species. Filter feeding animals generally possess large amounts of these neurotoxins.

KEY WORDS: Phallusia nigra, tunicate, paralytic shellfish toxins, tetrodotoxin. Nerve preparation was performed using crab leg sensory nerve.

EUROSURVEILLANCE 15/01/15 Detection of the pufferfish toxin tetrodotoxin in European bivalves, England, 2013 to 2014.

We demonstrate that TTX is present within the temperate waters of the United Kingdom, along the English Channel, and can accumulate in filter-feeding molluscs. The toxin is heat-stable and thus it cannot be eliminated during cooking. While quantified concentrations were low in comparison to published minimum lethal doses for humans, the results demonstrate that the risk to shellfish consumers should not be discarded. Background Tetrodotoxin (TTX) is the causative agent responsible for pufferfish/fugu poisoning, a fatal marine poisoning found predominantly in tropical regions. It is found mainly in the organs of fish from the Tetraodontidae family, as well as other marine species such as the blue-ringed octopus and gastropods [1].

Figure. The mean primary to secondary SRM peak ratios were 1.87 ± 0.13 (7%) for the TTX standards and 1.83 ± 0.26 (14%) for the average of all TTX-positive samples. Table 1. Toxins 2015, 7(5), 1779-1807; First Detection of Tetrodotoxin in Greek Shellfish by UPLC-MS/MS Potentially Linked to the Presence of the Dinoflagellate Prorocentrum minimum.

During official shellfish control for the presence of marine biotoxins in Greece in year 2012, a series of unexplained positive mouse bioassays (MBA) for lipophilic toxins with nervous symptomatology prior to mice death was observed in mussels from Vistonikos Bay–Lagos, Rodopi.

This atypical toxicity coincided with (a) absence or low levels of regulated and some non-regulated toxins in mussels and (b) the simultaneous presence of the potentially toxic microalgal species Prorocentrum minimum at levels up to 1.89 × 103 cells/L in the area’s seawater. Further analyses by different MBA protocols indicated that the unknown toxin was hydrophilic, whereas UPLC-MS/MS analyses revealed the presence of tetrodotoxins (TTXs) at levels up to 222.9 μg/kg.
