Norway -Crab shells in Agder: DSP below limit value


On 22 September, the Norwegian Food Safety Authority received a response to new samples of crabs in Agder. The random samples show that diarrhea toxin (DSP) in the crabs is now below the limit value, but there is no guarantee that all crabs in the area are below the danger limit. The Norwegian Food Safety Authority recommends following the mussel warning, as the crab likes to eat mussels.

Earlier in September, the Norwegian Food Safety Authority found high concentrations of the algae poison DSP (Diarrhetic Shellfish Poisoning) in crab from Agder, and thus warned people to eat the contents of crab shells.

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.
