4. Minors used for packaging: A kilo of calcium carbide is as cheap as R100 and can ripen over 100 dozen mangoes.

Migrant labourers from UP, Jharkhand, Bihar and West Bengal,including minors, pack these in small paper envelopes with their bare hands, using no safety equipment.

5. These envelopes are then concealed between the raw mangoes.

Atleast 2-3 packets of envelopes are concealed in a mango box and preserved for 36 hours. When the outer surface of mangoes show a yellow colouration, the envelopes are removed.

6. Ready for sale: These artifically ripened mangoes are then sent to the retail markets, where unsuspecting consumers buy them in dozens.

7. Side effects of consumption:
Calcium carbide is known to cause cancer. It also causes food poisoning, gastric irritation and mouth ulcers.

On ingestion, it causes digestive, respiratory and gastrointestinal tract burns, nausea, vomiting, bloating and headache.

Calcium carbide: Calcium carbide is banned in India under the Food Safety and Standards Act, 2006.

Skin: Causes irritation, rash, and possible burns

Eyes: Calcium carbide can be extremely irritating to the eyes. Water in them causes the formation of corrosive calcium hydroxide, exposure can damage vision and lead corneal damage

Lungs: Inhalation may cause irritation of the mucous membranes in the respiratory tract. High exposure may lead to a dangerous build-up of fluids in the lungs (pulmonary oedema), which can be fatal
