The main manifestations are acute gastrointestinal symptoms such as nausea, vomiting, abdominal pain, diarrhea, etc. Some of them may be accompanied by dizziness, headache, chest tightness, shortness of breath and other symptoms. The cause of bean curd poisoning is related to its content of saponin, phytohemagglutinin, and trypsin inhibitors. Acute phase poisoning symptoms can usually occur within a few minutes of ingesting uncooked bean curd, usually no more than 5 hours. Most patients have increased leukocytes, most have normal body temperature, and the duration of illness is usually a few hours, a few can be up to 1-2 days. Generally, symptomatic treatment and appropriate rehydration can effectively reduce the patient’s symptoms, improve the body’s water and fluid loss, and correct ionic disorders. People with obvious symptoms of poisoning or those who are old and frail should be given symptomatic supportive treatment in time and given appropriate medication under the guidance of a doctor. It is recommended that when eating bean curd, either way of consumption should be fully cooked to destroy the toxins it contains. If uncooked bean curd is ingested, it should be promptly induced to vomit, and when uncomfortable symptoms occur it needs to be promptly taken to the emergency room for catheterization and gastric lavage.
