There are some algae and algae species causing marine poisoning in shellfish. The poisons they produce have negative effects on human health and environment and are transported through the food chain and damage the ecosystem. One group of these toxic compounds that enter into humans and intoxication belongs to the Diarrhetic Shellfish Poison (DSP) group. The cause of these intoxications in humans is ocaic acid, which contains poisonous C38 fatty acid.

Most of the toxins contained in shellfish, in particular, are heat-resistant and inactivated by cooking and other heat treatments. In addition, these poisons are not recognized as their appearance and flavor and are not understood during consumption and cause significant health risks.

Diarrhea shellfish poisoning (DSP) is caused by ocyclic acid produced by dinoflagellates, dinophysis toxin, yessotoxin and pektenotoxins. The first such poisoning occurred in the Netherlands in 1960. Then in Japan, more than a thousand people were disturbed by the consumption of shellfish contaminated with such poisons. In the investigations, it was determined that the poisoning was caused by dinoflagellates.

Toxins which cause poisoning of dense seafood are oil soluble compounds. The first toxin chemically identified in this group is ocaic acid. To date, there has been no deaths in humans due to the toxicity of dense shellfish. However, ocadaic acid stimulates tumor activity and causes permanent liver damage.

This type of poisoning is mostly caused by shellfish such as mussels and clams.

In advanced laboratories, Diarrhetic Shellfish Poison Group (DSP) intoxication analyzes are performed by using in vivo method within the scope of biotoxin analysis. These analyzes are based on standards and test methods published by national and international organizations.
