| Abstract |
Consuming the meat of some marine turtles can lead to a specific type of seafood poisoning known as chelonitoxism. A recent poisoning event (March 2024) on the Tanzanian island Pemba, resulting in the death of 9 people and hospitalization of 78 others, underscores the need to obtain an up to date overview and understanding of chelonitoxism. Here, we document a global overview of poisoning incidents resulting from the consumption of sea turtle flesh worldwide. All events combined involved over 2400 victims and 420 fatalities. Incidents were predominantly reported in remote regions (often islands) across the Indo-Pacific region. Reported health effects of consuming poisonous sea turtles include epigastric pain, diarrhea, vomiting, a burning mouth and throat sensation, and dehydration. In addition, ulcerative oeso-gastro-duodenal lesions, which occasionally have resulted in hospitalization and death, have been reported. Lyngbyatoxins have been suggested as (one of) the causative agents, originating from the cyanobacterium Moorena producens, growing epiphytically on the seagrass and seaweed consumed by green turtles. However, due to the limited evidence of their involvement, the actual etiology of chelonitoxism remains unresolved and other compounds may be responsible. The data outlined in this review offer valuable insights to both regulatory bodies and the general public regarding the potential risks linked to consuming sea turtles. |
