Tanzania – 3 Children Die After Consuming Sea Turtle Meat, 22 People Hospitalised – Algal Toxins?

Republic World

Three children lost their lives after consuming sea turtle flesh on Pemba Island in Tanzania’s Zanzibar. On November 27, police reported that all of the children who died belonged to the same family. According to Juma Sadi, the regional police chief for Pemba North, 22 additional individuals have been brought to hospitals after eating sea turtle flesh on Friday, Xinhua reported.

The police added that samples of the sea turtle flesh have been delivered to the appropriate authorities for testing to examine the cause of the fatalities. “Two of the people admitted to hospital are children and they are in critical condition,” Juma Sadi was quoted by Xinhua as saying. He further highlighted that the sea turtle flesh is suspected of being poisonous.

Algae on the seafloor are known to discharge deadly poisons between the months of November to March when the nation’s temperatures rise and during these months, sea turtles, as well as over 20 kinds of fishes, feast on toxic algae at the bottom of the seafloor. Further, the poisons in the plants eventually seep into the flesh of the organisms that consume them. It has the potential to be lethal if eaten.

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.

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.

New Zealand – Shellfish biotoxin alerts – Hawkes Bay

MDPI

North Island warnings

Hawke’s Bay

Reason for alert Paralytic Shellfish Poisoning (PSP)

Check the symptoms of PSP

Date warning issued 16 June 2021

Media release

Affected area From the Mohaka River mouth, south to Cape Kidnappers.
Shellfish affected Mussels, oysters, tuatua, pipi, toheroa, cockles, scallops, catseyes, kina (sea urchin), and all other bivalve shellfish.

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 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.
Other information Paralytic shellfish toxins have been detected in shellfish from Pania Reef at levels over the safe limit of 0.8mg/kg set by MPI. Ongoing testing will continue and any changes will be communicated accordingly.
