In the past fisherman that caught puffer fish would simply throw it back into the sea. But nowadays the pufferfish has been prepared by unlicensed fish monger and disguised as crystal fish selling at a low price. About 20RM per kilogramme. Normally, white flesh fish are more expensive.
Consumption of small amounts of Pufferfish can lead to death and there is no antidote if such an accident occurred. Japan, in general, serves the puffer fish with a licensed chef that takes many years of training before they are ready to serve the fish.
But in Malaysia, the fish are prepared by foreign labour or in Singapore we love to use the phrase ‘foreign talent’.
