A detailed study done by Atmakaru Ramesh and Ambalatharasu Vijayalakshmi , Department on Pesticfide Chemistry to evaluate the residues of Endosulfan which may have accumulated in environmental samples due to regular aerial spraying application of endosulfan on cashew leaf plantation for a period of 20 years. All the samples were analyzed for the totoal residuesof endosulfan, endosulfan sulfate and also the potential hydrolysis product endosulfan diol, using gas chromatography with electron capture detection. The Analysis of soil, dried leaf samples, cow milk, fish and water showed negligible residues of endosulfan
Hence, the report has dismissed the link between endosulfan and the disease in Kasargod .
