Dutch authorities are investigating a concerning outbreak of Newcastle Disease impacting pigeon populations across the Netherlands, with the first confirmed case detected in Groningen this August[[3]]. This highly contagious viral disease, while rarely affecting humans, poses a meaningful threat to both wild bird populations and the commercial poultry industry[[1]]. The Dutch Wildlife Health Center is currently analyzing samples from multiple provinces, including Limburg, South Holland, and amsterdam, to determine the extent of the spread and potential strain of the virus.
Dutch health officials are investigating an outbreak of Newcastle Disease among pigeons, with a significant number of sick and deceased birds reported since August 2025, particularly in the Groningen province. The Dutch Wildlife Health Centre (DWHC) has been conducting extensive pathological examinations on samples collected from affected pigeons.
The DWHC confirmed the presence of Newcastle Disease in one pigeon from Groningen, a reportable poultry disease that requires notification to the Netherlands Food and Consumer Product Safety Authority (NVWA). This discovery comes as similar clinical signs have been observed in pigeons across multiple regions of the Netherlands.
Reports indicate that affected pigeons exhibit a range of symptoms, including lethargy, a hunched posture, lying on their side or back, head drooping, and disorientation. These symptoms are concerning as Newcastle Disease can be highly contagious among bird populations.
Currently, the DWHC is also investigating pigeons from Limburg, South Holland, and Amsterdam, with Newcastle Disease among the suspected causes. Full pathological examinations are being performed on these birds to determine the extent of the outbreak and identify any potential spread.
Newcastle Disease is a viral infection with pigeons serving as its natural host. The virus spreads through respiratory secretions and gastrointestinal fluids, such as saliva and feces. It is a remarkably stable virus in the environment and can remain infectious for several weeks, posing an ongoing risk to susceptible birds.
Common clinical signs of the disease include apathy, watery or bloody diarrhea, twisting of the head and neck, loss of balance, and paralysis of the wings. Infected birds undergoing molting may also experience brittle or deformed feathers. While rare, human exposure to the virus can cause mild conjunctivitis, typically resolving without treatment.
The recent findings underscore the importance of ongoing wildlife disease surveillance and rapid response to prevent wider outbreaks. Continued monitoring and investigation by the DWHC and NVWA are crucial to understanding the dynamics of this Newcastle Disease outbreak and protecting both wild bird populations and poultry farms.
