Moves are afoot to seek organic certification for cashew nuts grown in southern India.

The Plantation Corporation of Kerala is hoping to achieve organic certification for its cashew nuts following the controversy over its use of Endosulfan for aerial spraying in its plantations, reports The Hindu.

The Corporation stopped using Endosulfan in 2001. It is reported that traces of the chemical pesticide can remain in the soil up to 800 days, a period which will soon lapse.

Endosulfan has been linked to skin disease, lymph node enlargement, chronic asthma and cancer, although this applies to workers involved in the pesticide spraying rather than consumers who eat the nuts.
