Cyanide poisoning suspected in death of 15 Kenya elephants

Fifteen elephants found dead outside Amboseli National Park in southern Kenya are suspected to have been poisoned by eating tomatoes sprayed with pesticides on adjacent farms, according to the BBC.

The Kenya Wildlife Service (KWS) stated that preliminary laboratory tests on samples taken from the carcasses identified cyanide. Ten of the animals showed signs of paralysis before dying within a two-day period. The remaining five elephants were already dead when officials discovered them.

Scale of mortality

The KWS reported that these deaths occurred over a one-month period between 24 June and 24 July 2026. This represents the first time in decades that elephant deaths of this magnitude have been recorded in this region. Officials noted that the carcasses include elephants of different sexes and ages, which suggests the deaths were not confined to a single demographic or family group.

Ecosystem and human risk

The Amboseli ecosystem is a large area straddling the border with Tanzania. The Amboseli Trust for Elephants reported that the ecosystem contained more than 2,000 elephants in 2025. The incident has highlighted tensions regarding expanding agricultural activities near the park, as elephants frequently enter farmland to find water and food.

Wildlife authorities told local media that the toxic substances consumed by the animals do not pose an immediate risk to humans. While investigations continue, the KWS has ruled out foul play as the cause of the deaths.
