New Delhi, Aug 04: Delhi government on Friday banned the sale of soft drinks in schools in the Capital. Many political parties yesterday sought a ban on the sale and production of colas in the country following studies showing the presence of pesticide in them.

Centre for Science and Environment came out with a fresh study claiming the presence of “pesticide cocktail” in 11 brands of soft drink giants Coca Cola and Pepsico, three years after the same brands were found to have contained pesticides.

The Indian Soft Drink Manufacturers Association, of which Pepsico and Coca-Cola are members, said the soft drinks were safe to consume.

“The soft drinks manufactured in India comply with stringent international norms and all applicable national regulations,” the industry body said in a statement.

The new study found three to five different pesticides in 57 samples of Coca-Cola and Pepsico drinks produced in 12 states, CSE said.

The average amount of pesticide residues found in the samples was 11.85 parts per billion (ppb), 24 times higher than the permitted limit of 0.5 ppb recently drafted — but not yet implemented– by the Bureau of Indian Standards, a government agency that sets safety and hygiene standards for commercial products.

In some cases, the levels were up to 200 times the limit.
