In 2011, the Ministry of Food, Agriculture and Livestock issued the Special Hygiene Regulations for Animal Foods. This regulation describes the specific hygiene conditions that food enterprises producing animal food must comply with the principles set out in the Food Hygiene Regulation. According to the Regulation, the total amount of marine biotoxins measured in the bodies or edible parts of shellfish shall not exceed:

  • For the sum of ocadaic acid, dinophysis and pecteno toxins, 160 okg / kg as the equivalent of ocadaic acid
  • 1 mg / kg equivalent of yesso toxins for yesso toxins
  • 160 azg / kg as azaspiric acid equivalent for azaspiric acids

Diarrhetic Shellfish Poison Group health problems caused by toxins include nausea, vomiting, diarrhea and abdominal pain. However, no deaths have occurred due to these toxins. Nevertheless, these toxins are observed to cause the development of gastric tumors.

Mostly, shellfish, such as mussels and clams, cause poisoning. Ocaic acid detected in the body of these organisms causes poisoning. In European Union countries, according to the 91 / 492 EEC directive, for human health, shellfish do not require the presence of ocaic acid.

Azaspiric acid 2 and 3 (AZA-2 and AZA-3) are methyl and dimethyl analogs of azaspiric acid 1 (AZA-1) and have been identified on the UK, Ireland and Norway coast. They all cause crustal poisoning.

Azotpiric acid 3 (AZA-3), which is among the analysis of liquid chromatography - mass - mass spectrometry method and Diarrhetic Shellfish Poison Group (DSP) intoxication, is also performed in authorized laboratories within the scope of biotoxin analysis. These analyzes are based on standards and test methods published by domestic and foreign organizations.
