Africa Science News Service reports that USAID signed a contract that allows U.S. money to be used to purchase DDT for Indoor Residual Spraying (IRS) against malaria-carrying mosquitoes.
If so, this is one of the final barriers to use of U.S. funds for DDT use. Oddly, the news report offers no details on when or where the contract was made.
DDT use in Uganda was halted pending a suit by Uganda agricultural businesses to stop the spraying. The contract discussed would allow purchase of other insecticides to be used in place of DDT for IRS.
It’s important to note that no environmental organizations have expressed opposition to the limited use of DDT in IRS applications. It may be significant to note that the programs involving indoor spraying fall into the category of integrated pest management, which is what Rachel Carson urged in her 1962 book, Silent Spring.
