Once someone has symptoms of food poisoning such as vomiting, diarrhea and abdominal pain. They should immediately stop eating poisoned food, call 120 to call the emergency center for help, and send the poisoned person to the hospital for gastric lavage, catharsis and enema.

For those who are poisoned for a short time without obvious vomiting, you can first stimulate the root of your tongue with your fingers and chopsticks to induce vomiting, or let the poisoned person drink a lot of warm water and induce vomiting repeatedly to reduce the absorption of toxins.

If the vomit is a clear liquid after vomiting with a lot of warm water, you can drink milk in moderation to protect the gastric mucosa. If bloody liquid is found in the vomit, suggesting that there may be gastrointestinal bleeding or pharyngeal bleeding, vomiting should be temporarily stopped. When convulsions and spasms occur, immediately move the patient to a place where there are no dangerous goods around, take chopsticks, wrap them with handkerchiefs, and stuff them into the patient's mouth to prevent biting his tongue.

If patients eat toxic food for a long time (such as more than two hours) and are in good mental state, they can take laxatives to promote the excretion of toxic food.

Because it is very important to determine the toxic substances used for treatment, after food poisoning occurs, food samples that lead to poisoning should be kept for testing in hospitals. If there is no food sample around, you can also keep the patient's vomit and excrement for the convenience of doctors.
