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.
