Real news on a topic like DDT takes a while to filter into the public sphere, especially with interest groups, lobbyists and Astro-Turf groups working hard to fuzz up the messages.
News from the DDT Expert Group of the Conference of the Parties to the Stockholm Convention was posted recently at the Stockholm Convention website — the meeting was held in early December in Geneva, Switzerland.

In the stuffy talk of international relations, the Stockholm Convention in this case refers to a treaty put into effect in 2001, sometimes known as the Persistent Organic Pollutants Treaty (POPs). Now with more than 152 signatory nations and 178 entities offering some sort of ratification (not the U.S., sadly), the treaty urges control of chemicals that do not quickly break down once released into the environment, and which often end up as pollutants. In setting up the agreement, there was a list of a dozen particularly nasty chemicals branded the “Dirty Dozen” particularly targeted for control due to their perniciousness — DDT was one of that group.
DDT can still play a role in fighting some insect-carried diseases, like malaria. Since the treaty was worked out through the UN’s health arm, the World Health Organization (WHO), it holds a special reservation for DDT, keeping DDT available for use to fight disease. Six years ago WHO developed a group to monitor DDT specifically, looking at whether it is still needed or whether its special provisions should be dropped. The DDT Expert Group meets every two years.
Here’s the press release on the most recent meeting:
Stockholm Convention continues to allow DDT use for disease vector control
Fourth meeting of the DDT Expert Group assesses continued need for DDT, 3–5 December 2012, Geneva

The Conference of the Parties to the Stockholm Convention, under the guidance of the World Health Organization (WHO), allows the use of the insecticide DDT in disease vector control to protect public health.
The Stockholm Convention lists dichlorodiphenyltrichloroethane, better known at DDT, in its Annex B to restrict its production and use except for Parties that have notified the Secretariat of their intention to produce and /or use it for disease vector control. With the goal of reducing and ultimately eliminating the use of DDT, the Convention requires that the Conference of the Parties shall encourage each Party using DDT to develop and implement an action plan as part of the implementation plan of its obligation of the Convention.
At its fifth meeting held in April 2011, the Conference of the Parties to the Convention concluded that “countries that are relying on DDT for disease vector control may need to continue such use until locally appropriate and cost-effective alternatives are available for a sustainable transition away from DDT.” It also decided to evaluate the continued need for DDT for disease vector control at the sixth meeting of the Conference of the Parties “with the objective of accelerating the identification and development of locally appropriate cost-effective and safe alternatives.”
The DDT Expert Group was established in 2006 by the Conference of the Parties. The Group is mandated to assess, every two years, in consultation with the World Health Organization, the available scientific, technical, environmental and economic information related to production and use of DDT for consideration by the Conference of the Parties to the Stockholm Convention in its evaluation of continued need for DDT for disease vector control.
The fourth meeting of the DDT Expert Group reviewed as part of this ongoing assessment:
- Insecticide resistance (DDT and alternatives)
- New alternative products, including the work of the Persistent Organic Pollutants Review Committee
- Transition from DDT in disease vector control
- Decision support tool for vector control.
The DDT expert group recognized that there is a continued need for DDT in specific settings for disease vector control where effective or safer alternatives are still lacking. It recommended that the use of DDT in Indoor Residual Spray should be limited only to the most appropriate situations based on operational feasibility, epidemiological impact of disease transmission, entomological data and insecticide resistance management. It also recommended that countries should undertake further research and implementation of non-chemical methods and strategies for disease vector control to supplement reduced reliance on DDT.
The findings of the DDT Expert Group’s will be presented at the sixth meeting of the Conference of the Parties, being held back-to-back with the meetings of the conferences of the parties to the Rotterdam and Basel conventions, from 28 April to 11 May 2013, in Geneva.
Nothing too exciting. Environmentalists should note DDT is still available for use, where need is great. Use should be carefully controlled. Pro-DDT propagandists should note, but won’t, that there is no ban on DDT yet, and that DDT is still available to fight malaria, wherever health workers make a determination it can work. If anyone is really paying attention, this is one more complete and total refutation of the DDT Ban Hoax.
Rachel Carson’s ghost expresses concern that there is not yet a safe substitute for DDT to fight malaria, but is gratified that disease fighters and serious scientists now follow the concepts of safe chemical use she urged in 1962.
