Puffer fish is a banned food in the country. Does it have its origin?

The State Food and Drug Administration's "Notice on Issues Related to Catering Service Providers' Handling of Puffer Fish" (Food and Drug Administration Office Shihan [2011] No. 242) and "On Cases of Food Poisoning Caused by Handling of Puffer Fish" Notice on Matters Related to Administrative Penalties" (Food and Drug Administration Food Letter [2011] No. 12) In some places, specialized people will raise puffer fish. The reason why eating is prohibited is entirely because many restaurants buy puffer fish from informal channels for cheap. Fish, or improper processing and cooking techniques, has led to too many poisoning incidents.
