Fifth Expert Group Meeting on DDT

The Fifth Expert Group Meeting on DDT was held from 10 to 12 November 2014 in Geneva, Switzerland.

Venue: International Environment House-1 (IEH-1), 11-13 chemin des Anémones, 1219 Châtelaine, Switzerland. 

Background: DDT is listed in Annex B of the Stockholm Convention with its uses in disease vector control as an acceptable purpose in accordance with Part II of Annex B of the Convention. 

The DDT expert group is established in consultation with the World Health Organization to assess, every two years, the available scientific, technical, environmental and economic information related to production and use of DDT.

The sixth meeting of the COP, concluded that countries that are relying on DDT for disease vector control may need to continue such use until locally safe, effective, affordable and environmentally sound alternatives are available for a sustainable transition away from DDT. It also decided to evaluate the continued need for DDT for disease vector control on the basis of available scientific, technical, environmental and economic information, including that provided by the DDT expert group at its seventh meeting, with the objective of accelerating the identification and development of locally appropriate, cost-effective and safe alternatives.

Meeting objectives: To facilitate the Conference of the Parties (COP) to the Stockholm Convention in its evaluation of continued need for DDT for disease vector control.

Outcomes: The 5th meeting of the DDT Expert Group was attended by 18 experts representing 14 countries, WHO and UNEP. The experts observed, among other things, that:

  • There is no clear trend in global DDT production and trade over the past five year period. 
  • The management and the generation of an inventory of DDT stockpiles remains a global challenge. 
  • A range of potential substitute chemicals and new tools for vector control are under development. Some of these alternatives will be sufficiently developed for policy recommendation in the next two to five years.
  • The lack of capacity by national programs to monitor and respond to the increasing levels of insecticide resistance and outdoor transmission in malaria vectors is a serious threat to vector control programmes.

The DDT Expert Group recognized that there is a continued need for DDT for indoor residual spraying (IRS) in specific settings for disease vector control where locally safe, effective and affordable alternatives are still lacking.
