Thiruvananthapuram: Kerala has informed Tamil Nadu that vegetables brought from that state were found to have pesticide residue three to five times more than the permissible limit.

This was noticed during random visits recently to certain farmlands in nine districts in Tamil Nadu by a team of Food Safety officials from Kerala after the state launched a drive against sale of vegetables with high pesticides content coming from neighbouring states in the wake of Maggie noodles controversy.

State government, based on a report prepared by a team of Food Safety officials, has written to Tamil Nadu in this regard, Commissioner of Food Safety T V Anumapa said on Thursday.

It was a follow up action to the decisions taken at the meeting convened by Chief Minister Oommen Chandy on June 10 to check the flow of such vegetables to the state.

"Food Safety officials from the state visited two-three farmlands in nine districts of adjacent Tamil Nadu and prepared the report". The officials visited farmlands in nine districts including Nagercoil, Dindigul, Tirunelveli and Kodaikanal, she said.

An inter-state secretary level meeting has been planned next month to discuss the matter. Kerala was concerned on the issue because at least 80 per cent of the state's vegetable needs are met by neighbouring states.

Meanwhile, Agriculture Scientist Dr Thomas Biju Mathews of Agricultural University here said normally test results are not conclusive as random samples from open market and neighbouring states are usually taken for the tests.

"The results are always changing. It is a continuous monitoring process", he added.

On tests conducted on vegetable coming from other states, he said trace level of pesticide was 10 per cent on the samples tested.
