Kenya investigates death of 15 elephants in Amboseli, possibly from toxic substance

Kenyan wildlife authorities are investigating the mysterious deaths of 15 elephants in the Amboseli ecosystem, with preliminary findings suggesting exposure to a "possible toxic substance." The Kenya Wildlife Service (KWS) reported that the deaths occurred between June 24 and July 24 across the Amboseli National Park, Kimana Sanctuary, and Kuku ranch area.

Ten of the deceased elephants displayed similar clinical signs, including partial paralysis that rendered them unable to stand before succumbing within one to two days. The remaining five carcasses were too decomposed or scavenged to determine a cause of death. The affected animals were primarily adult females and their calves, with only one adult male reported dead.

In response, the KWS deployed veterinarians from Nairobi, Tsavo, and Amboseli national parks to investigate, treat affected animals, conduct post-mortems, and collect samples for laboratory analysis. Preliminary results from the University of Nairobi indicated the presence of a possible toxic substance in samples from several affected elephants.

However, the KWS stressed that further quantitative analyses are underway to ascertain the concentration and significance of these findings. Investigations are also ongoing to pinpoint the substance's origin. Preliminary tests from the Government Chemist Laboratory were negative for the examined toxins, but tests for other potential toxins continue. Environmental investigations, including water source and contaminant analysis, are also being conducted to identify a common exposure source.

The KWS assured the public that there is no evidence of risk to human health or transmissibility to humans. Surveillance in the Amboseli ecosystem has been intensified, and the KWS is collaborating with scientific partners to definitively determine the cause of the elephants' deaths.
