According to Assoc. Prof. Nguyen Duy Thinh, former lecturer of Food Technology Institute, Hanoi University of Technology, cyanide is extremely toxic chemicals, even included in the list of unique substances in toxins.They are quickly absorbed into the body, quickly inhibited, strong with cell respiration, the nervous system causing acute poisoning, a very small dose can also be fatal.

Cyanide poisoning makes the body unable to exchange oxygen.Fast deaths often due to respiratory failure, convulsions.The dosage of cyanide poisoning depends on the form (salt or gas), the time of contact and the contact line.

The signs to identify when the cyanide poisoning is to feel headache, dizziness, uneasiness, drowsiness, sometimes convulsions, nausea, rapid breathing, high heart rate, feel restless and exhausted.At first, it will breathe rapidly, the heart rate increases, but then the cardiovascular collapse, hypotension.If the cyanide poisoned within 2 hours is not treated promptly, it will risk cardiac arrest, apnea and death.

In cases of eating foods containing cyanide or professional related to this substance, the symptoms often take place slowly and severe severity increases over time.For example, people with poisoning may blur vision, reduce vision;Paralysis of legs are more legs than both hands and symmetrical.This situation is common in people who eat cassava regularly every day, especially the malnutrition, the higher the risk.Cyanide poisoning can cause hormonal disorders, hypothyroidism.

When detecting people showing signs of drowsiness, coma, shortness of breath, it is necessary to go to the hospital as quickly as possible for emergency resuscitation.Poisoning situations or cyanide poisoning will usually not be seen from the beginning, unless they are exposed to cyanide.

If you do not know the source of poison, do not know what causes but still suspect poisoning or poisoning, please call for advice immediately to a doctor specializing in poisoning.This helps find the cause and source of poison, thereby preventing timely poisoning.

According to experts, cyanide can survive in many natural foods such as seeds of some fruits (plums, peaches, apricots, apples).Among the most likely to cause cyanide and fresh bamboo shoots - a common food in the meals of many Vietnamese families.

This toxin has water -soluble properties and evaporates at high temperatures.With the best lush bamboo shoots families should soak for hours in water before processing, cyanide will decrease when exposed to water.

You should boil bamboo shoots thoroughly, change water several times to remove toxins.Sour sour bamboo shoots are ripe, have a unique sour smell, turn new yellow to use, absolutely do not eat raw bamboo shoots.

Fresh cassava also contains cyanide toxin in both skin and meat.When boiled, especially boiled in large quantities, this substance will be scumed on the water surface.People who eat this substance with high content will be poisoned, folk or called "drunk" cassava.In fact, many people who eat cassava die from cyanide in cassava.

According to experts, the best way to remove cyanide in cassava is to peel, cut the head, tail, then soak in cold water for hours before boiling.In addition, during boiling, open the lid to make the cyanide fly away, the amount of toxins will be significantly reduced.
