Why Lift Ban on DDT?

I was shocked to hear the news that the World Health Organisation(WHO) had lifted the ban on DDT for mosquito control in Africa.

DDT, an Organochlorine insecticide, was banned world-wide some 30 years ago, not only because of the associated hazards to users when carelessly handled, but mainly because of its high toxicity to man and other living organisms and its persistence in the environment which can result in the pollution of water bodies, the soil and the environment at large.

The use of DDT can lead to cancers and other serious illnesses in humans and animals and it is therefore surprising that the WHO which together with the Environment Protection Agency (US-EPA) are advocating the use of DDT again.

The WHO have decided even the less toxic chemicals which fall within the WHO/US-EPA class II (e.g some Carbamates, and Nitroguanidiness) should be phased out by the year 2015, can now see the ban lifted on DDT, a highly toxic class I chemical.

The loss of innocent lives that occurred in Benin in year 2001 caused by the misuse of Endosulfour, as well as the death of a baby elsewhere caused by DDT residue found in a nursing mother,s breast milk, are still fresh on our minds.

For example, the on-going sanitation campaign in Ghana and the use of safer and non-persistent chemicals such as the pyrethtoids, to mention but a few are good alternatives.

I entreat the appropriation authorities in Ghana and, indeed, the whole of Africa to halt this dangerous proposed action before it is too late.
