The Use of DDT and Recommendations: The GOI has already banned DDT in the agricultural sector and restricted its use in public health to 10,00 metric tons a year — except in the case of a major outbreak. The actual use of DDT is far below this ceiling. In 1993, WHO studied the use of DDT for controlling vector borne diseases, and after
careful review concluded that: (i) DDT exposure as a result of indoor residual spraying does not provide convincing evidence of adverse effects; and (ii) there was limited justification on toxicological or epidemiological grounds for changing current policy towards indoor residual spraying of DDT, recommending that DDT can be safely used for
indoor spraying. However, recognizing that DDT has low vector mortality in many settings, and potentially adverse effects on the environment, it was decided that: 1) BHC will be banned for use from April, 1997; 2) the use of DDT should be gradually phased out and the available alternative utilized for public health programs (DDT will only be
used for targeted epidemic prone areas and malaria endemic regions); 3) the GOI will review the parameters of DDT use on an annual basis; and 4) as part of the enhanced malaria control program, the NMP will develop specific guidelines for criteria and complete data requirements needed to evaluate the efficacy of insecticides (DDT and
others) used for vector control by 1998 to include:
