A Zoo Miami employee has been hospitalised after reportedly falling ill while preparing a greater kudu antelope for transfer to another facility. The incident has raised concerns regarding the potential exposure to thiafentanil, a powerful opioid used to sedate the animal, which might have affected the staff member during the procedure.

According to a statement from Zoo Miami, the staff member was assisting in the immobilisation of the greater kudu, which was undergoing a routine medical assessment ahead of its relocation. During the procedure, the employee began exhibiting symptoms of illness, prompting immediate action from the zoo’s medical team.

As a safety measure, the employee was administered Narcan, an emergency medication utilised to counteract the effects of opioid exposure. Following this, they were promptly transported to Jackson South Medical Centre for further evaluation. Thankfully, the employee reportedly remains stable and is under careful observation to ensure their wellbeing.

Thiafentanil, the drug responsible for the sedation of the greater kudu, is commonly used by veterinarians to temporarily immobilise animals during medical treatment. However, it comes with significant risks; it is explicitly labelled unsafe for human interaction, necessitating stringent precautions when being employed around handlers. The zoo is currently investigating whether the employee’s symptoms were indeed a result of accidental contact with the drug, likely through exposure to the animal’s saliva.
Exposure to thiafentanil can manifest in a range of symptoms, including dizziness, nausea, and constricted pupils. In more severe cases, individuals may face life-threatening symptoms such as respiratory difficulties, low blood pressure, or even loss of consciousness. Given the potential severity of this incident, Zoo Miami has not yet confirmed the specifics surrounding the employee’s condition or the cause of their illness.
The greater kudu antelope, central to this incident, is a large species indigenous to East and Southern Africa. Notable for their impressive spiral horns that can exceed three feet in length, greater kudus are social animals, often living in mixed-sex herds of up to 25 members. The zoo’s commitment to the care and safe transfer of its animals remains a priority, and updates regarding the incident are anticipated.
In light of this incident, Zoo Miami has been urged to reinforce safety protocols and training among staff when handling potent sedative drugs. The incident has highlighted the need for continued vigilance and education regarding the risks of veterinary medications not intended for human use.
As details continue to unfold, PEOPLE has reached out to Zoo Miami for additional information regarding both the employee’s condition and the broader context of the incident. The community remains hopeful for a swift recovery for the staff member involved and is awaiting further clarification from the zoo on this unexpected event.
