A devastating outbreak has killed 72 tigers in less than two weeks at a popular tourist attraction in northern Thailand, prompting an investigation by local authorities. The deaths occurred at Tiger Kingdom Chiang Mai, a park where visitors can interact closely with the big cats, raising concerns about disease transmission and animal welfare.
The facility, which houses a total of 240 tigers across two locations, reported the rapid succession of deaths earlier this month. The situation highlights the vulnerability of captive animal populations to infectious diseases and the challenges of maintaining their health in close proximity to humans.
Canine Distemper and Respiratory Bacteria Identified
Initial suspicions centered around contaminated chicken feed, recalling a similar outbreak of avian influenza at a tiger zoo in Chonburi province in 2004. However, testing revealed the presence of canine distemper virus, a highly contagious disease that affects the respiratory, gastrointestinal and nervous systems of susceptible animals. The virus is typically found in dogs but can also infect big cats.
In addition to canine distemper, tests on the tigers’ carcasses also detected a bacteria associated with respiratory disease. “By the time we realised they were sick, it was already too late,” Somchuan Ratanamungklanon, director of the national livestock department, said last week. Early detection can be difficult in tigers compared to more commonly observed animals like domestic cats and dogs.
Authorities have confirmed that the virus is no longer spreading and no further tiger deaths have been reported. No human infections have been identified, though personnel who worked closely with the animals were placed under a 21-day observation period as a precautionary measure. The remains of the deceased tigers have been buried, and euthanasia was recommended for the most severely ill animals.
Animal welfare organizations have used the incident to raise concerns about the conditions in which tigers are kept in Thailand. The Wildlife Friends Foundation Thailand criticized the “extreme vulnerability of facilities for wild animals in captivity to infectious diseases.” PETA Asia stated that “tragedies like this would be far less likely to occur” if tourists avoided such establishments.
The Tiger Kingdom Chiang Mai has been temporarily closed for disinfection. The outbreak serves as a stark reminder of the potential health risks associated with close contact between humans and wild animals, and the importance of robust disease surveillance and prevention measures in captive animal facilities.
