Very relevant posting for this summer season when we all relish a lot of juicy and delicious fruits. From this post we can learn about the food value of mangoes. But in recent years the scenario has changed. Our dishonest business men are using calcium carbide as a ripening agent for mangoes. as a result, they do not need to wait for a certain time to get the ripe mango. Rather they are getting ripe mangoes within a very short time using this poisonous chemical on the unripe mangoes. But do they ever think of the consequence of consuming these poisonous mangoes? May be they remain blind of the fact thinking of their instant profit earning. But we, the consumers, should be aware of the bad effect of this calcium carbide on our health. Consumption of carbide ripened fruits is extremely hazardous for health, mainly for the nervous system. Acetylene, generated from carbide reduces oxygen supply to the brain. In acute stage, it causes headache, vertigo,dizziness,delirium, seizure and even coma. In the long term, it may produce mood disturbance and loss of memory too. Immediately after consumption, there may be abdominal pain, vomiting and diarrhoea.
