Newcastle Disease Outbreak in Germany: A Growing Threat to Poultry Farms

A highly contagious animal disease, Newcastle disease, previously considered under control in Germany for three decades, is experiencing a resurgence. Outbreaks have been confirmed in poultry farms in Brandenburg and Bavaria, prompting concerns and preventative measures across the country.

Recent Outbreaks and Culling Efforts

As of Wednesday morning, approximately 125,000 birds have been culled as a precautionary measure in response to confirmed outbreaks. The Friedrich Loeffler Institute (FLI) has classified the situation as a serious threat to poultry farming in Germany. Source

Specifically, six detections of the virus have been confirmed in the Erding district of Bavaria, in addition to the initial two cases identified in Brandenburg. Authorities are actively investigating to determine if additional outbreaks have occurred. Source

Understanding Newcastle Disease

Newcastle disease, also known as atypical avian influenza, is a highly contagious viral infection that can affect all bird species. While human infection is rare, it is possible, typically resulting in conjunctivitis. Although, the FLI notes that fatal outcomes have been documented in immunocompromised individuals. Source

Mandatory Vaccination and Ongoing Risks

Germany has a mandatory vaccination program for chickens and turkeys against Newcastle disease. However, the FLI emphasizes that vaccination does not provide complete protection. Vaccinated birds are less susceptible to infection, shed less virus, and exhibit milder symptoms, but culling affected flocks remains necessary to control the spread of the disease. Source

The current situation is complicated by ongoing outbreaks in neighboring countries, including Poland, the Czech Republic, and Slovakia, affecting both commercial farms and smaller, hobby farms. The simultaneous circulation of bird flu among wild birds further exacerbates the risk. Source

Preventative Measures

The FLI stresses the importance of heightened awareness and strict biosecurity measures on poultry farms. This includes controlled movement of people and goods, as well as prompt testing of sick or deceased birds. Source

In Erding county, approximately 39,500 laying hens are affected. Source and Source
