Investigation into Tiger Deaths in Chiang Mai
Authorities in Chiang Mai, a city in northern Thailand, are conducting an investigation following the deaths of numerous tigers at a well-known tourist destination this month.
Within less than two weeks, seventy-two tigers died across two facilities of Tiger Kingdom Chiang Mai, a park where visitors have the opportunity to touch and interact with tigers.
The local livestock department reported that samples taken from the deceased tigers tested positive for the canine distemper virus; however, officials have not yet confirmed the source of the outbreak.
During a press conference held on Tuesday, officials stated that the virus was no longer spreading and no additional tiger fatalities had occurred. They also confirmed that no humans had contracted the virus.
Authorities indicated that the remains of the deceased tigers have been buried, and a recommendation was made to euthanise tigers that were critically ill.
According to local media, the affected big cats were part of a population exceeding 240 tigers housed across the two Tiger Kingdom Chiang Mai facilities.
Details on the Disease and Additional Findings
Canine distemper virus is a highly contagious illness that affects the respiratory, gastrointestinal, and nervous systems of its host. Although it is commonly found in dogs, it can also infect large felines, often resulting in fatal outcomes.
In addition to the canine distemper virus, the provincial livestock office in Chiang Mai reported last week that samples from the tiger carcasses also tested positive for bacteria linked to respiratory disease.
Local media reiterated that the infected tigers were among more than 240 living at the two Tiger Kingdom Chiang Mai sites.
Somchuan Ratanamungklanon, director of the national livestock department, previously told local media,
"By the time we realised they were sick, it was already too late,"noting the difficulty in detecting illness in tigers compared to animals such as cats or dogs.
On Tuesday, Somchuan informed reporters that officials had collected samples from the tigers' bodies, the chicken they consume, and their environment.
Earlier, the provincial livestock office had indicated that preliminary tests showed the tigers had been infected with feline parvovirus. Some local officials initially suspected that the outbreak might have originated from contaminated raw chicken meat fed to the tigers, as reported by the Bangkok Post.
Raw chicken was also suspected as the cause of a significant bird flu outbreak at a tiger zoo in Chonburi province in 2004, which resulted in nearly 150 tigers dying or being euthanised to prevent further spread of the influenza.
Health Monitoring and Animal Welfare Concerns
The disease control department stated over the weekend that although none of the veterinarians or staff working in the Chiang Mai tiger enclosures had contracted canine distemper virus, they were placed under observation for 21 days, according to Thai PBS.
Animal rights organizations have highlighted this incident as indicative of the poor living conditions of captive tigers used for entertainment purposes in Thailand.
Wildlife Friends Foundation Thailand issued a statement emphasizing that the tiger deaths revealed the
"extreme vulnerability of captive wildlife facilities to infectious disease".
Peta Asia also commented,
"Tragedies like this would be far less likely to happen" if tourists "stayed away" from these attractions.
Tiger Kingdom Chiang Mai has been temporarily closed for two weeks while officials conduct disinfection procedures.
