The Newcastle Disease outbreak has been a recent one, raising concerns in Europe, with numerous cases reported in 2026. Official surveys conducted by the Department for Environment, Food and Rural Affairs and European animal health authorities have indicated that the disease is spreading to countries such as Poland, Germany, and Spain. Avian influenza is a very contagious viral disease that afflicts poultry and other birds, leading to massive losses in the agricultural sector. The cases that have re-emerged, including commercial farm infections, have heightened the biosecurity concerns and elevated the level of risk overall in Europe.
Newcastle Disease Spreads Across Europe: Impact & Risk Factors
- Several countries in Europe, including Poland, Germany, Spain, Lithuania, and Slovakia, have officially reported cases of the disease.
- Poland is the most affected nation, and the outbreaks in 2026 affected up to 1.8 million birds.
- Germany reported its first outbreak since 2008 (or decades for poultry), meaning that it has re-emerged in areas that were controlled.
- Poultry farms in Spain, both commercial and non-commercial, have also experienced outbreaks.
- The disease is induced by avian paramyxovirus type-1 (APMV-1) and is transmitted very fast among birds.
- It impacts the respiratory, digestive, and nervous systems, which in most cases causes high mortality rates in poultry.
- The symptoms in the infected birds are coughing, sneezing, paralysis, diarrhoea, and lack of appetite.
- The outbreak has seen authorities raising the risk levels in some areas, such as Great Britain, to medium.
- Transmission is associated with the flight of wild birds, commerce, infected equipment, and farm biosecurity breaches.
- The European Commission has put in place emergency control areas and movement restrictions to control the disease.
- Vaccination exists but is not quite efficient, and that is why strict biosecurity is necessary.
- Governments note that Newcastle disease is a notifiable disease, and they should report suspected cases immediately.
- International trade and poultry farming are at risk of facing a severe economic threat due to the outbreak.
- Continuous monitoring systems, such as the Animal Disease Information System (ADIS), are monitoring cases in Europe.
- Experts caution that unless containment measures are well adhered to, the disease can keep on spreading to the west.

Conclusion – Newcastle Disease
Newcastle disease continues posing a significant risk to the health of poultry in the world because of its high transmissibility and the cost implications. It can cause massive death and trade losses to affect the respiratory, digestive, and nervous systems in birds. Strict biosecurity, early detection, and vaccination measures need to be put in place to ensure effective control. Being a notifiable disease, it is important to report promptly. In general, poultry industries and food security on the global level require constant supervision and proactive strategies to avoid outbreaks.
