Chiang Mai, Thailand – A devastating outbreak of disease has claimed the lives of at least 72 captive tigers at several wildlife parks in northern Thailand, prompting a two-week closure of the popular Tiger Kingdom Chiang Mai and a sweeping investigation into the cause. The outbreak, which began around February 8th, has raised concerns about animal welfare and biosecurity at tourist attractions offering close encounters with big cats.
The majority of the deaths occurred at Tiger Kingdom Mae Taeng and Tiger Kingdom Mae Rim, two privately operated parks known for allowing visitors to interact closely with tigers. According to a timeline released by the regional Protected Area Office, 51 tigers died at Mae Taeng and 21 at Mae Rim between February 8th and February 19th. The situation has prompted authorities to quarantine the facilities and initiate disinfection protocols in an effort to contain the spread of the illness. The scale of the losses is described as “very unusual” by Kritsayarm Kongsatri, director of Chiang Mai’s wildlife conservation office.
Identifying the Culprits: A Complex Viral Combination
Preliminary tests conducted by livestock officials indicate that the tigers were infected with feline parvovirus, likewise known as feline panleukopenia. This highly contagious virus severely attacks the digestive system and immune response, causing symptoms such as vomiting, bloody diarrhea, high fever, lethargy and loss of appetite. However, further laboratory analysis revealed a more complex picture. Autopsies confirmed the presence of canine distemper virus (CDV) and Mycoplasma bacteria in the deceased tigers, suggesting a combination of infections contributed to the high mortality rate. Notably, tests ruled out the presence of influenza A, which causes bird flu. The Independent reports on the initial findings.
Feline parvovirus is particularly dangerous, and canine distemper, while more commonly associated with dogs, can be fatal in big cats. Mycoplasma, a bacterial infection affecting the respiratory system, can exacerbate pneumonia and breathing problems, especially in animals with compromised immune systems. Veterinary experts emphasize the challenges of treating tigers compared to domestic animals. “Treating sick tigers is very different from treating dogs and cats,” explained Somchuan Ratanamungklanon, director-general of Thailand’s department of livestock development, to local media. “Dogs and cats live closely with us, so when they show symptoms, we can respond and provide treatment right away. Tigers, however, aren’t living closely with humans. By the time we notice that something is wrong, the illness may already be advanced.”
Investigation Focuses on Raw Chicken Feed
The investigation into the source of the outbreak is ongoing, but initial suspicions center on raw chicken meat supplied by a private farm and used as feed for the tigers. Authorities are stressing that the exact cause has not been confirmed, but the possibility of contamination is being thoroughly investigated. The Bangkok Post reported on February 20, 2026, that laboratory tests are being conducted on tiger carcasses at the Faculty of Veterinary Medicine at Chiang Mai University.
Surviving tigers have been moved to Tiger Kingdom’s care center in Mae Taeng district for monitoring and observation. The privately run Tiger Kingdom Chiang Mai has barred all non-authorized entry and begun a facility-wide disinfection campaign. Kritsayarm Kongsatri, director of the Protected Areas Regional Office 16 (Chiang Mai), confirmed the large number of tiger deaths and stated that the Department of National Parks, Wildlife and Plant Conservation will dispatch a team to observe and support the investigation.
Concerns About Tourist Interaction and Biosecurity
The incident has reignited debate about the ethics of allowing close interaction between tourists and captive wild animals. The Tiger Kingdom parks, and similar facilities, attract a significant number of visitors eager to pose for photographs with tigers. Critics argue that these interactions can be stressful for the animals and increase the risk of disease transmission. The close proximity between humans and tigers also presents a potential pathway for zoonotic diseases – diseases that can spread from animals to humans – to emerge.
The current outbreak highlights the importance of robust biosecurity measures at wildlife parks and tourist attractions. These measures should include strict hygiene protocols, regular health monitoring of animals, and careful sourcing and testing of food supplies. Effective quarantine procedures are also crucial for preventing the spread of disease. The Thai authorities are now reviewing existing regulations and considering whether additional safeguards are needed to protect both animal and public health.
Impact on Tourism and Conservation Efforts
The temporary closure of Tiger Kingdom Chiang Mai is expected to have a negative impact on local tourism. The park is a popular destination for both domestic and international visitors, and its closure will result in lost revenue for the tourism industry. However, officials emphasize that the priority is to contain the outbreak and ensure the health and welfare of the remaining tigers. Livemint details the temporary closure and ongoing disinfection efforts.
The loss of so many tigers is also a setback for conservation efforts. While these tigers were captive animals, their deaths underscore the vulnerability of tiger populations to disease. Tigers are already facing numerous threats in the wild, including habitat loss, poaching, and human-wildlife conflict. Protecting wild tiger populations requires a multifaceted approach that includes habitat conservation, anti-poaching measures, and disease surveillance.
Key Takeaways
- Disease Outbreak: At least 72 captive tigers have died in northern Thailand due to a combination of feline parvovirus, canine distemper virus, and Mycoplasma bacteria.
- Park Closure: Tiger Kingdom Chiang Mai has been temporarily closed for a two-week period to allow for disinfection and investigation.
- Investigation Focus: The investigation is currently focused on raw chicken meat used as feed, but the exact cause of the outbreak remains unconfirmed.
- Biosecurity Concerns: The incident raises concerns about biosecurity measures at wildlife parks and the risks associated with close tourist interactions with big cats.
Authorities are preparing to vaccinate surviving animals to control the outbreak, but the long-term impact of this devastating event remains to be seen. The investigation is expected to continue for several weeks, and a full report will be released once all the laboratory results are available. The next official update from the Chiang Mai Provincial Livestock Office is anticipated by March 8, 2026, regarding the progress of the investigation and the status of the surviving tigers.
