Investigators are working to unravel the circumstances surrounding the death of 16 elephants in the Amboseli ecosystem, marking the largest recorded die-off of these animals in the area in decades.

The crisis began when the first incident was reported on June 24, prompting the immediate deployment of veterinary teams.

Most of the affected animals identified so far are adult females and calves. A multi-agency technical team has since been assembled to establish the precise source of poisoning behind the losses.

Laboratory investigations have ruled out an infectious or transmissible disease, directing experts toward environmental factors.

Scientists are currently matching laboratory findings to trace the exact exposure pathway. As part of these efforts, water samples are being analysed for potential environmental contamination.

In addition, authorities are examining whether pest control products may have contaminated the ecosystem. The Kenya Wildlife Service is also investigating if giant star grass played a role in contributing to the poisoning.
