Sažetak
In the middle and southern Adriatic Sea the shellfish farms (Mytilus galloprovincialis) and harvesting area of the natural populations of warty venus (Venus verrucosa) are located. The contamination of shellfish with marine biotoxins is a food safety and human health concern. During 2011, the period of DSP (diarrhetic shellfish poisoning) toxicity was recorded, within a national monitoring program by the official analysis of marine biotoxins. DSP shellfish toxicity was revealed by mouse bioassay as official methods for DSP toxins. In some areas, the occurrence of toxicity started in January 2011 and lasted until mid-summer, with a maximum number of DSP positive samples during May and June. All samples, DSP positive and negative, were analysed by LC-MS/MS method. The most of the DSP positive samples contained gymnodimine and spirolide in low concentrations. We determined the levels and seasonal distribution of the gimnodimine and spirolide in the middle and southern Adriatic Sea. Gymnodimine and spirolide are already recognized as highly toxic by injection, as well as, fast-acting because of the rapid onset of neurological disorders and short survival time.
