Recently, the Fuzhou Inspection and Quarantine Bureau first discovered the entrapment of frozen puffer fish from a group of imported ocean-going self-trapping aquatic products. According to the classification, the frozen puffer fish has a total of 5 boxes and weighs about 100 kilograms. All of the varieties are dark-finned porpoises. This is the first time that Fujian has found poisonous puffer fish from imported aquatic products.

Puffer fish with tetrodotoxin, tetrodotoxin colorless, tasteless, odorless, is one of the most toxic neurotoxins found in nature, it has a local stimulating effect on the intestine, and it quickly acts on nerve endings and nerve centers after absorption. Blocking nerve conduction, causing nerve paralysis, the toxicity is more than 1250 times higher than cyanide, 0.5mg can cause death.

The stability of tetrodotoxin is very high. It can only be destroyed by high temperature baking and steaming. It does not change under the action of low temperature freezing, ultraviolet irradiation and digestive enzymes. The visceral parts such as the liver and ovary of the dark-finned porpoise were found to be poisonous. If the freshness is not good, or the second freezing may cause the toxin of the toxic part to metastasize to the muscle.

The puffer fish has a high safety risk and belongs to foods that are prohibited from operating under Article 34 of the Food Safety Law of the People's Republic of China. According to the current management model, puffer fish cultured or produced in China can only be exported. .

At present, the Fuzhou Inspection and Quarantine Bureau has sealed the frozen puffer fish, and issued the “Notice of Inspection and Quarantine Treatment” in accordance with the “Administrative Measures on Inspection and Quarantine of Import and Export Aquatic Products” issued by the General Administration of Quality Supervision, Inspection and Quarantine, No. 135, supervising the importers for destruction.
