If you accidentally eat the internal organs or other toxic parts of puffer fish, you may die. If it can be found in time, it can be solved by inducing vomiting first, or the person who eats by mistake can be sent to the hospital for gastric lavage. At present, there is no particularly effective detoxification drug, so most of them are relieved by gastric lavage and vomiting after poisoning.

Wild puffer fish mainly live in seawater, and some live at the junction of fresh water and seawater. Before and after Tomb-Sweeping Day every year, they often appear in the middle and lower reaches of the Yangtze River.

Under normal circumstances, as long as you eat the puffer fish, they will not be too harmful to human beings.
