CIGUATERA ADVISORY
Advisory
by BFAR, DA

August 2001
The findings of the Bureau of Fisheries and Aquatic Resource in its
ciguatoxin monitoring activities show that the BARRACUDA species of fish
(belonging to family Sphyraenide) fished from Northern Palawan
waters and Honda Bay are positive for ciguatoxin. Higher concentrations
of the toxin were observed in all the livers of the samples. Hence,
the public is advised to avoid eating this species.
The Barracuda fish samples analyzed for the toxin measured (total
lengths) from a minimum of 35 cm. to a maximum of 140 cm. and weighing
from 200 grams to 13 kilograms. The livers of the samples had higher
concentration of the toxin while the stomach muscles of all the samples
also showed positive results.
Ciguatoxin is a toxin produced by microscopic and bottom dweller algae
called Gambierdiscus toxicus. This toxin is fat soluble. When
reef fishes graze or eat these organisms the toxin is assimilated in the
system of the fish. This toxin is highly concentrated in the internal
organs of fishes such as the livers, roe and etc. The brain and muscles
of the barracuda fish such as stomach muscles are found also to have
higher concentrations of the toxin.
There is no antidote for ciguatoxin. The symptoms of Ciguatera Fish
Poisoning are abdominal pain, numbness or tingling sensations in the
mouth and lip area, vomiting, diarrhea, headache, nausea, leg pain
progressing from down upward, body weakness and reversal sensations of
hot and cold wherein the hot objects feels cold and cold objects feels
hot.
The public is therefore advised to refrain from eating Barracuda
species of fish.
