In India environmental NGO Greenpeace undertaken a study over a year has allegedly found the presence of harmful pesticide residues including toxic dichlorodiphenyl trichloroethane in tea sold by leading brands across India.
Neha Sehgal, the Senior campaigner of Greenpeace told ‘We had carried out a study across many cities in India over the past one year to check the quality of tea leaves sold in cities. Our study has revealed the presence of residues of chemical pesticides in a majority of brands’.
She claimed that out of 49 samples tested by the non-profit organisation, around 34 (94 percent) contained residues of at least one pesticide and 29 (59 percent) of the samples contained a cocktail of more than 10 different pesticides in them.
Also 29 (59 percent) of the samples contained residues of at least one pesticide above the maximum residue limits set by the European Union.
‘We had, for this study collected samples from different retailers from cities like Delhi, Kolkata, Bangalore and Mumbai over a period from June 2013 to May 2014,’ she said.
Sehgal said there was a presence of DDT (a synthetic organic compound used as a pesticide) in 67 per cent of the tea samples. ‘Use of DDT has been banned in India since 1989.
Monocrotophos, termed as hazardous by the WHO was found in 27 samples. Tebufenpyrad, a pesticide not registered in India, and thus illegal was found in one sample. It can be very toxic for the liver,’ she said.
Sehgal urged tea companies to move the tea sector away from the pesticide treadmill and asked them to adopt an ecological agriculture farming approach. The tea companies need to support adoption of ecological agriculture approaches like Non Pesticidal Management for the safety of consumers, she said.
