Fifteen elephants have died in southern Kenya after apparently ingesting cyanide, a highly toxic chemical that wildlife officials suspect was used on nearby tomato farms. The Kenya Wildlife Service said preliminary testing of samples from the carcasses detected traces of cyanide, while 10 of the elephants reportedly showed signs of partial paralysis before dying. “Cyanide is a highly toxic chemical,” KWS director general Erustus Kanga said. “If elephants consume cyanide, they cannot survive a day or two.” Eventually, if this cyanide is truly the one that is in the system, then we are going to see a bigger impact,” he said.
