The death of 72 tigers at Tiger Kingdom in Chiang Mai last week has raised concerns about the source of the virus and bacteria responsible. Raw chicken meat from a private farm is suspected, as it was fed to all tigers at the two facilities in Mae Rim and Mae Taeng districts.

The tiger carcasses have been disposed of, either through cremation or burial, as confirmed by Kritsayam Kongsatree, director of Conservation Area Management Region 16. Each burial site is marked with identification numbers, and no parts were taken for sale. Despite strict protocols, the origin of canine distemper virus, Mycoplasma bacteria, and feline parvovirus remains undetermined, causing public speculation.
Initial assumptions pointed to avian influenza in the meat, but lab tests showed no genetic materials present. Veterinarian Wisit Arsaithamkul voiced concerns on social media about the disease management on site, linking the outbreaks to food sources rather than viruses alone. Among over 200 tigers consuming the same food, only three nursing cubs remained unaffected, suggesting contamination in the supply.
Results confirmed the virus, halting further necropsies to reduce risk. Wisit highlighted a systemic failure in epidemiological management, cautioning against ignoring lessons learned. He stressed the need to protect livestock, emphasizing that concealment of issues would hinder industry improvements. The site, managed by Khum Sue Trakarn Ltd., remains closed, impacting their operations, which include several Tiger Kingdom locations in Thailand.
Looking ahead, the focus will be on identifying the exact cause of the outbreak, while ensuring public and animal safety to prevent recurrence. The investigation continues as experts seek to clarify the origins of the deadly outbreak and implement stricter controls on animal food sources, reported Bangkok Post.
