Hundreds of elephants have died in Botswana recently. Researchers have sent samples to laboratories in Botswana, South Africa, the United States and Zimbabwe for testing. On August 7th, the Ministry of environment, natural resources protection and tourism of Botswana said that toxicological analysis of nine pesticides and chemicals that usually caused wild animal poisoning showed that all samples were negative. In addition, they ruled out elephant deaths due to two suspected mineral elements and starvation. The statement said the results obtained so far do not exclude the possibility of poisoning. Therefore, environmental factors, including naturally occurring toxins, are still being studied.
in addition, an international expert team recently published a review article in the African Journal of wildlife research, which suggested that the possibility of human poisoning, poaching, starvation and anthrax infection could be basically ruled out. The expert team called for a comprehensive and rapid epidemiological survey to grasp the local disease transmission dynamics and carry out in-depth laboratory research. They pointed out that it would be difficult to prevent a similar situation from happening again if the real cause of the deaths was not found. (MA Peimin, head office reporter)
