Azaspiracid was first discovered in Ireland in 1995 after a human intoxication event linked to the consumption of shellfish and has since been observed in wide areas of West and Northwest Europe. The origin of the neurotoxin azaspiracid has been identified as the dinoflagellate Azadinium spinosum [1]. Azaspiracid-3 (AZA3, 22-desmethyl-azaspiracid) is an analogue of AZA1 and it is a product of metabolism in shellfish [2]. Intoxication symptoms can include nausea, stomach cramps, headache, vomiting and diarrhea. The maximum permissible total level of AZA1, -2, and -3 in shellfish is currently 0.16 mg/kg in whole tissue.
