New Zealand – Public health warning about shellfish in Grove Arm, Marlborough Sounds – Diarrhetic Shellfish Toxins

MPI

The Ministry for Primary Industries (MPI) yesterday issued a public health warning advising the public not to collect or consume shellfish harvested from Grove Arm in the Marlborough Sounds.

Routine tests on shellfish samples taken from Okiwa Bay has shown levels of Diarrhetic Shellfish Toxins above the safe limit of 0.16 mg/kg set by MPI.  Anyone eating shellfish from this area is potentially at risk of illness.

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 within half an hour of ingestion and last for about 24 hours. Symptoms may include:

  • diarrhoea
  • vomiting
  • nausea
  • abdominal cramps

If anyone becomes ill after eating shellfish from an area where a public health warning has been issued, freephone 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. There is no commercial harvesting of shellfish in the affected area.

Iceland – Warning against consuming mussels from Hvalfjörður – Algal Toxins

MAST

Matvælastofnun continues to warn against picking and consuming mussels from Hvalfjörður, as DSP algae toxins were recently detected above the reference limits.  

DSP algae toxins in mussels can cause abdominal pain, diarrhea, nausea and vomiting. Symptoms appear soon after consumption and disappear within a few days. 

A representative of the Food Administration collected mussels on Friday 22 October at Fossá in Hvalfjörður. The purpose was to investigate whether it was safe for the public to pick mussels in Hvalfjörður. The results of the measurements showed that the DSP algae toxin was 440 µg / kg but a month ago 1150 µg / kg was measured in the mussel. Both values ​​are well above the limit of 160 µg / kg. 

Consumers are still warned not to eat mussels from the fjord as things stand. The agency will continue to monitor the situation and let them know when it will be safe to eat mussels from the fjord. During the winter, sampling is monthly, as algae growth is slow during the dark winter months and algae toxicity changes are slower. 

Finally, the Food Administration would like to draw attention to the fact that there is always a risk involved in consuming shellfish collected during shell picking, and this is always at your own risk.  

Hong Kong – CFS urges public not to consume a kind of chilled razor clams imported from Scotland suspected to be contaminated with lipophilic marine biotoxins

CFS

The Centre for Food Safety (CFS) of the Food and Environmental Hygiene Department today (October 4) urged the public not to consume a kind of chilled razor clams imported from Scotland due to possible contamination with lipophilic marine biotoxins. The trade should stop using or selling the product concerned if they possess it.

Details of the product are as follows:

Product name: Razor Clams
Brand: Lochleven Shellfish
Place of origin: Scotland
Importer: Longfine Seafood Trading Company Limited

A spokesman for the CFS said, “The CFS received a notification from the authorities concerned in Scotland through the International Food Safety Authorities Network (INFOSAN) that the above-mentioned product might have been contaminated with lipophilic marine biotoxins. According to the information provided by INFOSAN, the affected product has been imported into Hong Kong. Upon learning of the incident, the CFS immediately contacted the local importer concerned for follow-up.”

A preliminary investigation found that the above-mentioned importer had imported some of the affected product into Hong Kong. For the sake of prudence, the CFS has instructed the importer to stop sale and remove from shelves the affected batch of product and initiate a recall. Enquiries about the recall can be made to the importer’s hotline at 2387 2388 during office hours.

“Lipophilic marine biotoxins are a group of fat-soluble shellfish poisoning toxins which may cause symptoms such as diarrhoea, nausea and vomiting. In general, they are heat-stable and cannot be destroyed by cooking.” the spokesman said.

The spokesman urged consumers not to consume the affected product if they have bought any. The trade should also stop using or selling the product concerned immediately if they possess it.

The CFS will alert the trade to the incident, continue to follow up and take appropriate action. An investigation is ongoing.

USA – How to Report Seafood-Related Natural Toxin Illness

FDA

To help FDA effectively investigate, remove unsafe seafood products from the market, and develop new prevention strategies, the FDA relies on illness reporting from public health officials and healthcare providers. While most foodborne outbreaks are tracked through the FDA’s Coordinated Outbreak Response and Evaluation (CORE) network, seafood-related illnesses caused by natural toxins have a unique reporting mechanism. This web page provides information on commonly occurring seafood-related illnesses and how to report them to the FDA.  To report an illness from raw bivalve molluscan shellfish, email the FDA at shellfishepi@fda.hhs.gov.

The FDA receives reports of illnesses associated with the consumption of specific types of fish. These illnesses may originate from the activity of certain bacteria, toxins produced by marine algae, or hazards inherent in the fish.

Commonly occurring illness:

Illness and reporting information for the commonly occurring illnesses are provided in each section. Contact the FDA with any questions or need for clarification of the illness or reporting.

In addition to the illnesses listed above, reporting of other less frequently occurring illnesses from natural toxins may be accomplished by emailing the FDA at Seafood.Illness@fda.hhs.gov.  Refer to Chapter 6 of the “Fish and Fishery Products Hazards and Controls Guidance” for a comprehensive list of natural toxin illnesses. To report illnesses related to miscellaneous natural toxin illnesses, please email FDA at Seafood.Illness@fda.hhs.gov.

The FDA works with first responders, physicians, and state and local health departments to investigate illnesses and outbreaks, manage them, and learn how to lessen future occurrences.
