The Dangers of Pufferfish Poisoning

Pufferfish poisonings occur from eating undercooked

or poorly handled pufferfish.These rarely occur but can be severely life-threatening. It is said to be the second most poisonous creature in the world, next only to the Golden Poison Frog. It is estimated that one pufferfish can kill 30 adult human beings. Although considered a delicacy in Japan, called fugu, only licensed chefs are allowed to handle as a wrong cut could lead to death to whoever will eat it.

Pufferfish are also called balloon fish or blowfish. They are aptly named because of their ability to fill their highly elastic stomach with large amounts of air or water to give it a balloon-like shape. This serves as their defense mechanism to predators that may try to swallow these slow marine organisms. Some of the 120 species of pufferfish may also have sharp spines that are toxic.

The Deadly Toxin behind Pufferfish Poisoning

The deadly toxin behind pufferfish poisoning is called tetrodotoxin. The toxin is produced by the bacteria living in the pufferfish. Aside from pufferfish, the same toxin is found in toads, sunfish, porcupine fish, toad fish, globefish, and swellfish.  It is considered to be one of the most toxic poisons in nature. Although it is highly associated with consumption of pufferfish from waters of the Indo-Pacific regions, there have been a number of cases from the Atlantic Ocean and other bodies of water in the West.
