Eels contain a substance called histaminic acid. When eels die, histaminic acid is easily broken down into histamine. As the eel dies for a longer period of time, the decomposition of histaminic acid is accelerated under the action of bacteria, and more and more histamine will accumulate in the eel's body. Histamine is a poisonous substance that can easily cause poisoning after people consume it.
