Zimbabwe plans to send brain tissue samples from dead elephants to the United States to test for toxic micro-organisms blamed for hundreds of elephant deaths in neighbouring Botswana, the parks authority said. Thirty-four elephants have died in western Zimbabwe since Aug. 24, Parks and Wildlife Management Authority director general Fulton Mangwanya told a parliamentary committee in a statement on Monday. Botswana blamed toxins produced by cyanobacteria for the deaths of 330 elephants this year.
