Sprouted potato poisoning

Introduction to Germinated Potato Poisoning Potato (Solanumtuberosum), commonly known as potato or yam, is a Solanaceae, containing solanine. The poisoning component is solanine (C45H73O15N), also known as potato toxin, which is a weakly alkaline indole alkaloid, also known as Solanum nigrum, soluble in water. It is easily decomposed in the presence of acetic acid, high in heat, and can be detoxified by boiling. . Solanum sinensis is corrosive, hemolyzed, and has paralytic effects on the motor center and respiratory center. Each 100g potato contains only 5-10mg of Solanum nigrum; the immature, cautious potato or sprouted potato contains Solanum nigrum increased to 25-60mg, even up to 430mg. Therefore, eating a large amount of immature or sprouted potatoes can cause acute poisoning. basic knowledge The proportion of sickness: 0.0004-0.0008% Susceptible people: no specific population Mode of infection: non-infectious Complications: respiratory failure

Germination of potato poisoning

Dietary factors (45%):

When the potato is stored improperly, when the potato sprouts or partially turns green, the solanine is greatly increased, and the solanine is not removed or destroyed during cooking, and poisoning occurs after eating, especially in the late spring and early summer.

Solanum alkalosis (27%):

The solanine in the germinated potato is its toxic component. The potato usually contains less solanine in the normal case, and gradually increases during storage. However, after the germination of the potato, the content of the solanine in the young and bud parts of the potato increases sharply. It can cause poisoning. Solanine has a strong stimulating effect on the gastrointestinal mucosa, has a paralyzing effect on the respiratory center, and can cause cerebral edema and congestion. In addition, it has a hemolysis effect on red blood cells.

Germinated potato poisoning prevention

Potatoes should be stored at low temperature, avoiding sunlight, preventing sprouting, not eating too much buds, black-green skinned potatoes, potatoes with less buds should completely dig the buds of the buds, and cut off the skin around the buds. This kind of potato is not easy to fry. It should be boiled, stewed, braised and eaten. Add vinegar during cooking to accelerate the destruction of solanine.

Germinated potato poisoning complications Complications, respiratory failure

Can be complicated by central paralysis and respiratory failure.

Symptoms of germinated potato poisoning Common symptoms Abdominal pain, nausea, difficulty breathing, coma, diarrhea, convulsions

Acute germination of potato poisoning usually occurs in the tens of minutes to several hours after eating. It has a throat and mouth itching or burning sensation, followed by nausea, vomiting, abdominal pain, diarrhea and other symptoms. It is lighter in 1 to 2 days; Severe vomiting, loss of water and electrolyte imbalance, blood pressure decreased; severe poisoning patients have coma and convulsions, and finally died of respiratory central paralysis, and found to use 1:5000 potassium permanganate or 0.5% citrate immediately after poisoning Or tea to wash the stomach, supplement the liquid to correct the loss of water, actively give oxygen and apply appropriate amount of respiratory stimulant when breathing is difficult, respiratory center palsy with artificial respirator, immature cyan and sprouted potatoes are not edible, a little sprouted potato should be dug The germinated part, and soaked for more than half an hour, discard the soaking water, add water to cook thoroughly, pour the soup before it can be eaten, add some rice vinegar when boiled potatoes, because its toxic juice can be decomposed in the presence of acetic acid, becoming non-toxic.

Germination of potato poisoning

1. Do an emergency gastric lavage treatment first, and then do routine examinations after the condition is stable.

2, collecting specimens, such as excrement, vomit, feces remaining food, utensils, etc. No pathogens are usually detected. It can detect the solanine.

3, stool examination: no white blood cells or pus cells, there may be a small amount of red blood cells.

4, water and electrolyte examination: mainly includes water and sodium metabolism disorders, potassium metabolism disorders, magnesium metabolism disorders and calcium and phosphorus metabolism disorders. Respiratory acidosis combined with metabolic acidosis is often accompanied by hyperkalemia; respiratory acidosis with metabolic alkalosis often has hypokalemia and hypochloremia.

Diagnosis and identification of germinated potato poisoning

1. Eat a history of sprouted potatoes.

2. Clinical manifestations and signs.

3. Laboratory examination: Cut the remaining potatoes and add concentrated nitric acid or concentrated sulfuric acid near the buds. If it is rose red, it is proved that there is a solanine.

4. It should be differentiated from bacterial food poisoning: there is a history of unclean diet intake, and there are often epidemiological characteristics of multiple people with collective morbidity. Acute vomiting and diarrhea are the main clinical manifestations. The culture can find pathogenic bacteria.
