Elephant deaths in Amboseli ecosystem

Between June 24 and July 24, 2026, at least 15 elephants died in Kenya's Amboseli ecosystem, including Kenya — Amboseli National Park, Kimana Sanctuary, and the Kuku Ranch area. Ten elephants exhibited similar clinical signs, including partial paralysis leading to inability to stand, and died within one to two days. The condition primarily affected adult females and calves, with only one adult male reported. Preliminary laboratory findings from the University of Nairobi detected a potential toxic substance in samples from several affected elephants, though further quantitative analysis is needed to establish concentration and significance. Initial tests by the International — LGC Ltd were negative for the toxins examined, with additional testing ongoing. The Kenya — Kenya Wildlife Service (KWS) deployed veterinary teams from Nairobi, Tsavo, and Amboseli to investigate, conduct post-mortems, and collect samples. Environmental investigations, including testing water sources and other potential contaminants, are underway to determine if the elephants were exposed to a common source. KWS emphasized there is no evidence the incident poses a risk to human health and that the condition appears confined to affected elephants. Surveillance across the Amboseli ecosystem has been intensified.
