Comparison of Amnesic, Paralytic and Lipophilic Toxins profiles in cockle (Acanthocardia tuberculata) and smooth clam (Callista chione) from the central Adriatic Sea (Croatia)

Searching for Amnesic (ASP), Paralytic (PSP) and Lipophilic (LT) toxins in seafood is of great importance for consumer protection. Studies are usually focused on the most aquacultured species, the mussel. But, there are a number of potentially commercially important shellfish species as rough cockle Acanthocardia tuberculata (Linnaeus, 1758) and smooth clam Callista chione (Linnaeus, 1758) which are common in the Croatian Adriatic Sea. Investigation of marine biotoxins accumulation in these two species of shellfish from Adriatic Sea has not been conducted up to now. In order to detect the potential marine biotoxin profile of A. tuberculata and C. chione wild populations, samples were taken monthly during one-year survey from the estuarine area in the central Adriatic Sea. HPLC-FLD with pre-column oxidation and HPLC-UV-DAD methods were employed for PSP and ASP toxins determination, respectively, while LTs were determined by LC- MS/MS. This research had revealed the differences in the accumulation of ASP, PSP and LT toxins between the two studied species, as Acanthocardia tuberculata showed more diverse profile with higher concentrations of analysed toxins. Both investigated shellfish species had shown levels of these biotoxins under the legal limits set by the European Commission.
