The Kenya Wildlife Service (KWS) has launched a thorough investigation following the deaths of 15 elephants within the Amboseli ecosystem over the past month.

The fatalities occurred between June 24 and July 24, 2026, affecting elephants in Amboseli National Park, Kimana Sanctuary, and the Kuku Ranch area. Ten of the deceased elephants exhibited similar symptoms before death, including partial paralysis that rendered them unable to stand, leading to death within one to two days.

The affected group mainly consisted of adult females and their calves, with only one adult male reported among the deaths. The remaining five carcasses were too decomposed or scavenged, preventing definitive cause of death determinations.

Investigation Efforts

  • KWS quickly deployed veterinarians from Nairobi, Tsavo, and Amboseli to conduct on-site examinations and provide treatment to affected elephants.
  • Post-mortem examinations and sample collections were carried out, with samples sent to the University of Nairobi, Government Chemist, and other specialized labs for toxicological and pathological analysis.
  • Preliminary results from the University of Nairobi detected a potential toxic substance in samples, though further quantitative analysis is underway to assess its significance.
  • Tests by the Government Chemist have so far returned negative results for known toxins, prompting continued testing for other possible substances.

Environmental Assessments and Public Assurance

Beyond laboratory tests, environmental assessments are ongoing, including water source analyses and checks for contaminants in the affected areas to determine if elephants were exposed to a common hazard.

KWS has reassured the public that there is no current evidence suggesting any risk to human health, emphasizing that the condition appears confined to the elephants and is not transmissible to people.

Continued Monitoring

The agency has intensified surveillance across the Amboseli ecosystem and continues to monitor elephant populations closely. KWS remains committed to science-driven investigations and timely updates as it works with partners to establish the definitive cause of the deaths.
