Attention danger ! This is one of the potentially deadliest foods in the world. The fugu is actually a family of over 100 species of tetraodonidae (fish with a face that can be bloated). It contains a powerful poison in its liver and viscera: tetradotoxin, which is fatal to humans. It is therefore necessary a great know-how to take the fillets, without touching the toxic pockets. For the past ten years, under the effect of global warming, it has been found in the Mediterranean Sea (called harefish), which has already given rise to fatal poisonings in Greece or Turkey.
