Can You Still Eat a Snakehead Fish After It Dies? A Clear Guide to Judging

It is best not to eat a snakehead fish after it dies, unless it has just died, in which case there is no problem. Because the snakehead is a carnivorous fish, once it dies, bacteria in its body multiply rapidly, and eating it can cause physical discomfort, so it is best not to eat it. Generally you can pry open the gills and check whether the gill filaments have turned white; if they have turned white, it means it has been dead for a long time and is not suitable for eating.

Which fish cannot be eaten after they die?

Dead eel and soft-shelled turtle cannot be eaten. This is because eel contains relatively large amounts of histidine and trimethylamine oxide. After death, its histidine can be broken down into toxic histamine under the action of decarboxylase and bacteria. An adult can be poisoned by ingesting 100 mg at one time. Its trimethylamine oxide can be reduced to trimethylamine, intensifying its muddy fishy smell. In dead soft-shelled turtle, multiple histidines can be broken down into highly toxic histamine and histamine-like substances. Some people spray “Saomieling” in the fields, then catch the eels after they have been poisoned, which adds a new external source of poison to the eels.

The above is the relevant introduction on whether you can still eat a snakehead fish after it dies. We hope it is helpful to everyone.
