The Kenya Wildlife Service (KWS) has reported a significant development in the investigation of recent elephant deaths in Amboseli National Park. Between June 24 and July 24, 2026, 15 elephants died in areas including Amboseli National Park, Kimana Sanctuary, and Kuku Ranch.
Of these, 10 elephants exhibited similar symptoms such as partial paralysis, which rendered them unable to stand, leading to death within one to two days. The fatalities primarily involved adult female elephants and their calves, with only one adult male affected.
Investigation and Findings
Following the initial reports, KWS dispatched veterinarians from Nairobi, Tsavo, and Amboseli to conduct examinations, provide treatment, and collect samples for laboratory analysis. Samples were sent to the University of Nairobi, the Government Chemist, and other specialized labs for toxicological and pathological tests.
Preliminary results from the University of Nairobi detected a potential toxic substance in samples from several affected elephants. However, further quantitative tests are required to determine the concentration of the substance and its role in the deaths. The Government Chemist's initial screening for common toxins returned negative, with additional tests ongoing.
Challenges and Ongoing Efforts
- Five carcasses were too decomposed or scavenged, preventing determination of cause of death.
- Environmental assessments, including water source analyses, are underway to identify possible contamination sources.
- KWS has increased surveillance across the Amboseli ecosystem and continues monitoring elephant populations closely.
KWS Head of Communication, Duncan Wanyama, confirmed that the deceased elephants were found in various locations around the park, ranging from 15 to 30 kilometers from its boundaries. The public had called for swift action following widespread reports of the deaths.
