Abstract
The Food and Drug Administration (FDA) is advising consumers only to eat pufferfish (also
known as fugu, bok, blowfish, globefish, swellfish, balloonfish, or sea squab) from two known safe
sources. The risks associated with ingesting Tetrodotoxin due to the neurological damage that can
produce potential death have been well documented. For these reasons, the sale and consumption
of puffer fish must be controlled. Pufferfish have different toxin levels on species basis. There are
around 120 known species of pufferfish, the second most poisonous creature on the planet after the
Golden Poison Frog. The pufferfish is found in tropical waters worldwide, but they rarely go into
the cooler waters. If a fisherman catches a pufferfish, they will never touch the spikes as they are
highly toxic to humans and animals. Either the toxin is not found or the low level found species
can be consumed. Despite the pufferfish having such a deadly venom, there are some species of
pufferfish whose meat is eaten in Japan and Korea as a local delicacy. Special chefs are trained to
cut the fish so that the fish does not poison the consumer. Other species of pufferfish produce and
release a toxin into their organs when they die to harm the thing that ate them. According to
Japanese food safety standards, puffer fish with a toxicity level below 10 MU/g are considered safe
for human consumption. In addition, puffer fish consumption is allowed only if it is prepared and
cooked by a highly trained chef who has passed the necessary examination and has obtained a
license to cook puffer fish. Pufferfish must be cleaned and prepared properly so the organs
containing the toxins are carefully removed and do not cross-contaminate the flesh of the fish.
These toxins cannot be destroyed by cooking or freezing. Fugu (foo-goo) is a dish made from the
Pufferfish (blowfish) or Porcupine fish that has achieved an almost mythological status in western
cuisine. It has become synonymous with risk taking, a culinary Russian roulette, due to that, if
incorrectly prepared, a diner risks death from even a single bite due to a potent neurotoxin found
in the fish. Puffer fish liver oil can be extracted and used as a pharmaceutical drug.
