Whether food can be eaten after death is mainly judged by the length of death, whether there is smell or not, and whether it is rotten:

1, duration of death: Abalone can be eaten if its death time is less than one day, but its taste will be slightly worse; If abalone has been dead for a few days, you can't eat it any more to avoid diarrhea, abdominal pain and other symptoms.

2, whether there is an odor: abalone can be eaten without odor after death; If abalone smells after death, it can't be eaten, so as not to affect human health.

3. Decay: Whether abalone decays after death has a certain relationship with the length of death and the surrounding environment. Abalone can be eaten if it does not rot after death and there are no other abnormalities; If abalone has begun to rot after death, it can't be eaten, so as not to induce gastroenteritis, gastric ulcer and other diseases.
