Overview
- Authorities confirmed by PCR on June 16 that a velogenic strain of Newcastle disease was present at a broiler farm in Aldea de San Miguel and ordered sanitary emptying with disinfection now underway.
- The affected site housed about 24,000 43‑day‑old broilers and was not vaccinated against Newcastle disease.
- Veterinary services have immobilized the farm, destroyed carcasses, feed and other potentially infectious material, and set a 3 km inner ring and a 10 km outer ring for movement restrictions.
- Officials are tracing linked farms from the same integrator and plan to empty at least one nearby commercial holding while urging reinforced passive surveillance and stricter biosecurity on all farms.
- This is the 11th notified Newcastle focus in Spain since December and the first in Castilla y León, a pattern that raises concerns about wider sector losses and trade or supply disruptions across the EU, where authorities have recorded dozens of outbreaks since 2022.
