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.

New Zealand – Public health warning for shellfish reduced for West Coast, North Island – PSP Toxins
New Zealand Food Safety today reduced a public health warning against collecting shellfish in the Waikato and Taranaki region. The public health warning now extends from Albatross Point south to Oakura Beach and no longer applies to Kawhia and Aotea Harbours. More testing is being undertaken to determine the levels of paralytic shellfish toxins in the affected area.
Routine tests on shellfish samples taken from the Aotea/Kawhia Harbour area have shown levels of Paralytic Shellfish Poisoning (PSP) toxins are now within the safe limit of 0.8 mg/kg set by New Zealand Food Safety.
Mussels, oysters, tuatua, pipi, toheroa, cockles, scallops, catseyes, kina (sea urchin), and all other bivalve shellfish should not be eaten.
Note, cooking shellfish does not remove the toxin.
Pāua, crab, and crayfish may still be eaten if the gut has been completely removed prior to cooking, as toxins accumulate in the gut. If the gut is not removed, its contents could contaminate the meat during the cooking process.
Symptoms typically appear between 10 minutes and 3 hours after ingestion and may include:
- numbness and a tingling (prickly feeling) around the mouth, face, and extremities (hands and feet)
- difficulty swallowing or breathing
- dizziness
- headache
- nausea
- vomiting
- diarrhoea
- paralysis and respiratory failure and in severe cases, death.
If anyone becomes ill after eating shellfish from an area where a public health warning has been issued, phone Healthline for advice on 0800 61 11 16, or seek medical attention immediately. You are also advised to contact your nearest public health unit and keep any leftover shellfish in case it can be tested.
Monitoring of toxin levels will continue and any changes will be communicated accordingly. Commercially harvested shellfish – sold in shops and supermarkets, or exported – is subject to strict water and flesh monitoring programmes by MPI to ensure they are safe to eat.

Research – Marine Harmful Algal Bloom (HAB)-Related Illness Tracking
What are marine harmful algal bloom (HAB)-related illnesses?
When phytoplankton and algae in marine waters occur at levels that pose a health risk to humans, animals, and the environment, they are referred to as marine harmful algal blooms (HABs). The US Centers for Disease Control and Prevention (CDC) provide resources on potential human and animal exposures to marine HABs or associated marine biotoxins via skin contact or inhalation, or consumption of fish and shellfish.
- Marine mammals and birds may strand onshore with neurological symptoms associated with ingestion of marine HABs and marine biotoxins, particularly domoic acid (DA).
- People exposed to marine HABs via water contact may experience irritation of the eyes, skin, or respiratory system.
- People exposed to marine biotoxins via ingestion of contaminated seafood may experience nausea, vomiting, diarrhea or neurological symptoms. The most commonly occurring HAB biotoxins in California are paralytic shellfish poisoning (PSP) toxins and DA.
- Contact a medical provider or the California Poison Control System (1-800-222-1222) if you experience any of these symptoms after potential exposure to marine HABs or marine biotoxins.

Research – Emergent marine toxins risk assessment using molecular and chemical approaches
Cyanobacteria harmful blooms represent a deviation to the normal equilibrium in planktonic communities involving a rapid and uncontrolled growth. Owing to the capacity to produce toxins as secondary metabolites, cyanobacteria may cause huge economic losses in the fishing and aquaculture industries and poisoning incidents to humans due to their accumulation in the food chain. The conditions which promote toxic blooms have not yet been fully understood, but climate change and anthropogenic intervention are pointed as significant factors. For the detection of toxins in edible marine organisms, the establishment of international regulations and compulsory surveillance has been probed as exceptionally effective. However, not regulation nor monitoring have been settled concerning emergent marine toxins. In the light of this scenario, it becomes essential to apply fast and reliable surveillance methodologies for the early detection of cyanobacterial blooms as well as the occurrence of emergent marine toxins. Shotgun metagenomic sequencing has potential to become a powerful diagnostic tool in the fields of food safety and One Health surveillance. This culture‐independent approach overcomes limitations of traditional microbiological techniques; it allows a quick and accurate assessment of a complex microbial community, including quantitative identification and functional characterisation, in a single experiment. In the framework of the EU‐FORA fellowship, with the final goal of evaluate metagenomics as a promising risk assessment tool, the fellow worked on the development of an innovative workflow through state‐of‐the‐art molecular and chemical analytical procedures. This work programme aims to evaluate the occurrence of emergent marine toxins and the producing organisms in Cabo Verde coastal cyanobacteria blooms. Our results show the outstanding potential of a holistic metagenomic approach for the risk assessment of emergent marine toxins and the producing organisms. Additionally, we have also highlighted its value for the identification and evaluation of secondary metabolites as natural bioactive compounds with biotechnological and industrial interest.

Guatemala – Four deaths in Guatemala linked to contaminated shellfish – Saitoxin – PSP
More than 30 people have fallen sick and four have died in Guatemala after eating shellfish.
The National Commission for the Surveillance and Control of Red Tide in Guatemala has extended an alert because of the presence of saxitoxins above the limits on the coasts of Tiquisate, Escuintla, Retalhuleu and San Marcos.
Public health officials said that since the end of April, 34 people had been affected and three children and one adult had died.
Authorities urged the public not to eat bivalve mollusks such as mussels, clams and oysters.
A warning was issued earlier this month after monitoring and analysis detected high concentrations of saxitoxins above the limits.
Saxitoxin is a toxin responsible for paralytic shellfish poisoning (PSP). Harmful algal blooms are often called red tides.
