There will be many bacteria in the body after death, so you can't eat dead crabs. And you can't eat crabs raw, because there are many parasites in them. If eaten raw, some parasites will breed in the human body and cause harm to the human body. A few years ago, a child in our hometown ate river crabs raw and had parasites in his eyes. Finally, it took 50,000 to 60,000 yuan to cure, and I almost lost my life. This is not an alarmist but a true story, so river crabs can't be eaten after death. As long as you don't eat it, there is still no other toxicity.
