CRM-AZA-Mus
Mussel Tissue Certified Reference Material for Azaspiracids
Azaspiracids (AZAs) are a group of marine biotoxins containing both carboxyl and amine functional
groups (Figure 1). AZAs are produced by the small dinoflagellate Azadinium spinosum [1] and have
been shown to accumulate to high levels in a variety of shellfish species [2]. Human consumption of
shellfish contaminated with AZAs causes poisoning with symptoms resembling those of diarrhetic
shellfish poisoning [3]. The maximum permissible total level of AZA1, -2 and -3 in shellfish is currently
0.16 mg/kg in whole tissue [4]. CRM-AZA-Mus is a certified reference material (CRM) prepared from
naturally contaminated mussel tissues (Mytilus edulis) containing certified concentrations of AZA1, -2
and -3 (Table 1). CRM-AZA-Mus is designed to assist the analyst in assessing entire analytical
methods used to monitor AZA toxins in shellfish tissues. Each bottle contains approximately 8 g of
mussel homogenate with AZAs at levels appropriate for analytical testing.
