Fifteen elephants found dead in southern Kenya outside the Amboseli National Park are suspected to have been poisoned by eating tomatoes that had been sprayed with pesticides on nearby farms.
The Kenya Wildlife Service (KWS) reports that preliminary laboratory tests detected cyanide in samples taken from the animals' carcasses.
Ten of the elephants were found with signs of paralysis and died within two days; the other five were already deceased when discovered.
Investigations continue, and wildlife officials have ruled out foul play for the time being.
Wildlife authorities have told local media that the toxic substances eaten by the elephants pose no immediate risk to humans.
This incident heightens concerns about expanding farming activities near the park, as elephants often stray onto farmland in search of food and water.
The park and its surroundings form the Amboseli ecosystem, a vast area that straddles the border with Tanzania and is famous for its wildlife.
Officials say this is the first time in decades that elephant mortalities on this scale have been recorded in the region, despite successful anti-poaching measures.
The deaths involve elephants of different ages and sexes, suggesting the poison was not limited to a single family or demographic group.
The KWS said the deaths occurred between 24 June and 24 July 2026, coinciding with the 2025 population estimate of more than 2,000 elephants in the ecosystem as per the Amboseli Trust for Elephants.
