Fatal food poisonings from pufferfish in Cambodia have been ongoing for decades, with no previous documentation of the toxins or species involved.
Researchers studied three pufferfish species from the coastal waters of Sihanouk Ville, finding that two species, L. wheeleri and L. spadiceus, were non-toxic, while L. lunaris was toxic with elevated toxicity levels in all body tissues.
Tetrodotoxin (TTX) was identified as the primary toxin in L. lunaris, confirming it as a dangerous source of TTX and likely responsible for past poisonings in Cambodia.
