Between June 24 and July 24, 2026, the Amboseli ecosystem experienced its largest elephant die-off in decades, with 15 elephants found dead.

Kenya Wildlife Service (KWS) laboratory tests revealed cyanide presence in samples taken from the carcasses. Investigations suggest the elephants consumed tomatoes contaminated with pesticides, leading to poisoning.

The fatalities included both adult elephants and calves, with ten exhibiting paralysis symptoms before death. Notably, six of these deaths occurred within the Kimana Wildlife Sanctuary.

KWS has ruled out poaching as a cause and confirmed there is no immediate threat to human health. In reaction, rangers have increased surveillance efforts throughout the Amboseli ecosystem.

Authorities are also appealing to local farmers to handle pesticides responsibly to prevent further harm to wildlife.
