Bivalve sea creatures such as mussels, clams, clams and the like are fed with phytoplankton. However, the phytoplankton level increases from time to time in the seas. These increases have negative effects on the development of human health and tourism as well as on fisheries enterprises and fishermen. The phytoplankton type of fire color algae, which is estimated to be over 4, is around 200, causing a red-tide event by changing the color of the sea surface. Among them, algae in the vicinity of 40 produces toxins harmful to fish and shellfish.

The experts divide phytoplankton into three groups:

  • Some are phytoplankton species that cause harmless color changes in water.
  • Some of the phytoplankton species that cause the following diseases in humans consuming seafood:
    • Paralytic crustal poisoning (PSP)
    • Diarrheic shell poisoning (DSP)
    • Amnesic shell poisoning (ASP)
    • Ciguatera poisoning
    • Neurotoxic shell poisoning (NSP)
    • Blue-green algae poisoning
  • Some of them are phytoplankton species that do not have any toxic effect on humans, but especially clog the gills and damage fish and invertebrates.

Poisons from the Diarrhetic Shellfish Poison (DSP) species include pecototoxin (PTX) produced by dinophysis species. Toxicotoxin-induced poisoning has not been reported to date. However, recently measured values ​​are taken into account in European countries. Tumor-forming activities of ocadaic acid and DTX1 were determined.

Biotoxin analyzes in authorized laboratories include Diarrhetic Shellfish Poison Group (DSP) intoxication analyzes by LC-MS / MS method. In this context, analyzes are made for pectonotoxin, PTXs and neutral toxins. The standard considered in these analyzes is:

  • TS EN 16204 Foodstuffs - Determination of lipophilic algae toxins in shellfish and shellfish by LC-MS / MS (octadaic acid toxins, yessotoxins, azaspiracids, pectonotoxins)
