In the grape districts of western Maharashtra farmers don't use any pesticides for the export quality grapes.
But if you consume grapes with sprayed pesticides, a sensitive persons body reacts with a sore/irritations throat, mild fever next day after consuming.
To prevent this I usually wash the grapes in a aluminium stainer by holding it under hot water shower of 2.8 kw for 3 minutes. If the white stains of pesticide residues are still visible clean the grapes with a soft cleaning cloth, then again refrigerate it before consuming.
This has prevented me from having sore throat and fever after consuming grapes.
But if you get export quality grapes then a single wash is also not required.
One cannot resist/hold back - to consume farm fresh grapes if seen in front.
reports have come in about this unconventional use of the sweetened carbonated beverage from Warangal , Ramakrishnapuram, Khammam, Krishna and Guntur districts in Andhra Pradesh. As well as from Durg, Rajnandgaon and Dhamtari districts in Chhattisgarh where farmers say they have successfully used Pepsi and Coke to protect their rice crop against pests.
Hundreds of farmers in Andhra Pradesh and Chhattisgarh have discovered that spraying their cotton and chilly crop with one of the world's most famous beverages, Coke, to get rid of pests works out cheaper and as effective as the prohibitively expensive, patented pesticides being marketed by multinational chemical companies.
In 2003, the Centre for Science and Environment (CSE), a non-governmental organisation in New Delhi, said aerated waters produced by soft drinks manufacturers in India, including multinational giants PepsiCo and Coca-Cola, contained toxins including lindane, DDT, malathion and chlorpyrifos — pesticides that can contribute to cancer and a breakdown of the immune system.
Tested products included Coke, Pepsi, and several other soft drinks (7Up, Mirinda, Fanta, Thums Up, Limca, Sprite), many produced by The Coca-Cola Company.
CSE found that the Indian produced Pepsi's soft drink products had 36 times the level of pesticide residues permitted under European Union regulations; Coca-Cola's 30 times.
CSE said it had tested the same products in the US and found no such residues
