Bivalve molluscs living in the sea carry different risk factors compared to the fish and other sea creatures. These organisms, which are fed by filtering water, also absorb and accumulate biotoxins, chemical pests and pathogenic microorganisms in the water. People who consume these creatures such as mussels, clams and clams, therefore carry health risks. In general, the effects of microbiological contamination occur immediately in the human body, while the effects of chemical harmful substances are manifested in the long process. Therefore, the production of bivalve molluscs is controlled by a number of legal regulations, production areas are controlled and microbiological purification processes are performed when necessary.

Microbiological, toxic algae and water quality analyzes as well as biotoxin analyzes have an important place in the EU directives. Within the scope of biotoxin analysis, PSP, ASP, DSP, yesso toxin, azaspiric acids and similar analyzes are performed. In practice, biotoxin and phytoplankton analyzes are planned to be planned weekly.

Diarrhetic Shellfish Poison Group (DSP) toxins encountered in shellfish contain yessotoxin produced by algae of the species prorocentrum.

In the year 2014, the Ministry of Food, Agriculture and Livestock has amended the Regulation on Special Hygiene Rules for Animal Foods, and for the yesso toxins found in all bodies or edible parts of animals, the upper limit of 1 mg / kg, which is the equivalent of yesso tox, kg.

Within the framework of biotoxin analyzes in advanced laboratories, homo yesso toxin (hYTX) determination among Diarrhetic Shellfish Poison Group (DSP) intoxication analyzes are also performed. These analyzes are based on standards and test methods published by national and international organizations. The standard considered in this respect is:

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