How to distinguish whether eel is poisonous? I think it is not the first time for us to see the poisoning incident of eating eel. There was also a lawsuit about eel in ancient times.
Relatives and friends suspected that the woodcutter was poisoned by his wife, so they took him to the government. However, no matter how severely tortured, the woodcutter's wife just cried out her injustice and refused to admit her guilt. The magistrate had to detain her in prison.
A year later, when the new magistrate tried the case again, he thought that the case was strange. In order to further verify, he ordered the local people to catch more than 100 eels and put them in large tanks for observation, hoping to find out the answer.
For a long time, it was found that 7 eels always put their heads out of the water and did not sink into the water. The magistrate felt very strange, so he asked the cook to cook the seven eels and let a dead prisoner eat them. The prisoner died of abdominal pain soon after eating the eel.
It turns out that eating poisonous fish can cause death. The magistrate then acquitted the woodcutter's wife.
Why is eel poisonous? According to historical records, Qianshan County was a very developed place in China's paper making industry in the Ming Dynasty, and the famous Lianshi paper was produced here.
'Lianshi paper' is made from tender bamboo oars after bleaching and beating. Bleaching and beating are carried out in water, and a large amount of sewage is discharged every day. As time goes by, the adjacent waters are seriously polluted. The eels living here gradually accumulate toxic substances in their bodies through the food chain day after day, which naturally become the carriers of toxic substances. How can fish not be poisoned after being eaten?
Why do poisoned eels always raise their heads out of the water? Eels breathe by mouth, throat and skin. Eels are quiet. They usually lie at the bottom of the water.
After poisoning, the eel had to put its head out of the water to breathe because of the serious lack of oxygen in the body.
Xiaobian share: understand these, when you buy eels, do not buy those eels that will head out of the water.
