Norway -Do not eat the contents of crab shells in Agder – DSP Algal Toxin


The Norwegian Food Safety Authority warns people in Agder against eating the contents of the crab’s shells, following the discovery of diarrhea poison. The meat from the claws is safe to eat.

The Norwegian Food Safety Authority has found high concentrations of the algae poison DSP (Diarrhetic Shellfish Poisoning) in crab from Agder.

DSP is one of the most common types of mussel poisoning in Norway. Once the crab has eaten mussels with DSP, the crab becomes poisonous to people who eat it. DSP causes diarrhoea, nausea, vomiting and abdominal pain. It takes from half an hour to a few hours from the time you eat until you get sick. The symptoms disappear by themselves after 2-3 days.

Since the beginning of July this year, high levels of the algal toxin DSP have been detected in mussels along the Sørland coast, and in Agder the levels of the toxin have increased significantly in recent times. This is the reason why the Norwegian Food Safety Authority has also tested crabs in Agder for DSP.
