Sweden eradicates Newcastle disease after outbreak in laying hens

To combat the outbreak, Swedish authorities implemented stringent control measures. These included:

• Zoning and movement restrictions: Establishing restricted zones around the affected area to prevent the spread of the virus.
• Surveillance: Intensive monitoring of both the infected flock and surrounding areas to detect any further cases.
• Depopulation and sanitation: Culling the infected birds and thoroughly cleaning and disinfecting the premises.
• Traceability: Tracking the movement of birds and products to ensure no further spread of the disease.

Impact on the poultry industry

The outbreak had a significant impact on the local poultry industry. Farmers faced economic losses due to the culling of infected birds and the implementation of control measures. However, the swift response helped to minimize the long-term effects on the industry. The Swedish government provided financial support to affected farmers to help them recover from the losses incurred during the outbreak.

A successful eradication

The swift and effective response by Swedish veterinary authorities ensured that the outbreak was contained and eradicated within a few months. By January 2025, intensive surveillance confirmed that no new cases had emerged, allowing the World Organisation for Animal Health (WOAH) to declare Sweden free of Newcastle disease.

Global context

With Sweden’s successful eradication of the disease, only Poland and Israel remain with active reports of Newcastle disease. This highlights the importance of vigilant surveillance and rapid response measures in controlling the spread of such infectious diseases. The global poultry industry continues to face challenges from various diseases, and Sweden’s success serves as a model for other countries.

Conclusion

Sweden’s eradication of Newcastle disease demonstrates the effectiveness of coordinated veterinary efforts and stringent biosecurity measures. This achievement not only protects the country’s poultry industry but also serves as a model for other nations facing similar challenges. Continued vigilance and preparedness are essential to prevent future outbreaks and ensure the health and safety of poultry populations worldwide.
