![]() ![]() FUGU FISH DEATH PROFESSIONALPreparing and eating fished pufferfish or pufferfish received from someone else without the proper professional knowledge is extremely dangerous. ![]() Pufferfish may be an appealing food, but it is also important to remember that one can lose one’s life depending on how the fish is prepared. It has long been known that pufferfish contain deadly poison. ![]() Note: Fishing areas and processing methods are restricted. Lagocephalus lagocephalus (Blueback puffer) Lagocephalus inermis (Smooth-backed blowfish) Lagocephalus gloveri (Brown-backed toadfish) Has a silvery white and lustrous belt on the side of the body Many cases of pufferfish poisoning have occurred in the past due to amateurs with limited knowledge attempting to prepare pufferfish. There are other pufferfish species that resemble each other and, as shown in the able below, the parts which are poisonous differ for each, making it extremely dangerous if one is not able to differentiate them.ĭue to the difficulty in identifying species as noted about as well as changing poisonousness throughout the year and due to individual variation, professional knowledge and skills are required when eating pufferfish. FUGU FISH DEATH SKINThese latter contain poison not only in their livers but also muscles and skin and have resulted in accidents in the past. Many pufferfish species closely resemble each other in outward appearance, and some of these species contain poison in their muscle tissue.įor example, the edible species in the Lagocephalus genus and the Takifugu poecilonotus (Finepatterned puffer) closely resemble the poisonous Lagocephalus lunaris and Takifugu alboplumbeus. If this amount exceeds 10,000 mouse units, it can lead to death.Īs which parts are poisonous depends on the species of pufferfish, the ability to tell different pufferfish species apart is essential in pufferfish preparation. The amount of poison from ingested pufferfish is calculated as the amount of poison per gram for the part of the pufferfish eaten (mouse units/gram) × the amount eaten (grams). Mouse units are the unit used to represent the amount of pufferfish toxin, with one mouse unit equaling the amount of poison required to kill a 20 gram mouse in 30 minutes. The liver and ovaries of pufferfish exceed 10,000 mouse units per gram, meaning the tiniest amount will cause poisoning and can lead to death. Assuming 1,000 mouse units of poison per gram of pufferfish, just 10 grams is enough to cause death. The amount required to kill a person is aid to be around 10,000 mouse units. Tetrodotoxin is extremely deadly and is said to be 1,000 times stronger than potassium cyanide. This poison does not get destroyed during normal heating as part of cooking. The substance which causes pufferfish poisoning is called tetrodotoxin and is found in the liver and ovaries of pufferfish, as well as the skin and muscles in some species.

The fatality rate (the percentage of patients who die) of pufferfish poisoning is extremely high in comparison with other forms of food poisoning. Once consciousness is lost, the heart and breathing will stop, resulting in death.Ĭases of food poisoning due to pufferfish in the last 10 years (nationwide)
