After eating rotten rice, there was no reaction. What's the matter, or is it not time yet?

Not everyone has a reaction to this. Generally, poisoning occurs 2 ~ 4 hours after eating, and the time varies from 1 hour to about 6 hours, and suddenly nausea and severe vomiting (1 0 times in a day, sometimes bile blood and mucus are in the vomit), severe pain in the upper abdomen, diarrhea and watery stool, generally no fever, and the course of disease. This is often food poisoning caused by staphylococcal enterotoxin. It may be that the poisoning is mild and there are no symptoms for the time being.
