According to the patient's medical history, such as before the patient became ill, some special foods were eaten, such as overnight leftovers, leftovers, stale ingredients, or raw and cooked foods that were not separated. There are also some special foods, such as poisonous mushrooms, cassava, mandala, nitrites, organic pesticides, contaminated fruits, vegetables, puffer fish, etc., which should be highly suspected of food poisoning.

The harm to the human body caused by not being able to do aluminum phosphide mainly affects the nervous system and produces nausea and vomiting and other poisoning symptoms.

If it is in a humid environment, aluminum phosphide will absorb moisture in the air and react with the moisture in the air to produce a chemical substance that is toxic to the human body.

Aluminum phosphide decomposes when exposed to water, its toxicity is phosphine gas after decomposition reaction, if the amount of food is large, can not be eaten at one time, you can isolate and store it first, clean it before each practical time, there is no problem, pay attention to inhaling as little volatile gas as possible when cleaning, or soak first, and then rinse, you can eat with confidence.
