## Introduction
Avian influenza, also known as bird flu, has been a major concern for the poultry industry in Europe. However, recent reports suggest a gradual improvement in the situation, with a decrease in the number of new cases in domestic birds. While mortalities in wild birds continue to be reported, the overall trend is encouraging. This article provides an overview of the current status of avian influenza in European poultry, highlighting the key developments and measures taken to control the spread of the virus.
Decrease in Cases of Avian Influenza
According to the Animal Disease Information System by the European Commission, there have been 385 outbreaks of highly pathogenic avian influenza (HPAI) in commercial poultry across 21 European Union (EU) member states and neighboring countries since the beginning of 2023. This number is significantly lower compared to the 2,321 outbreaks registered in 2022.
France has been the most affected country, with 152 outbreaks, followed by Hungary with 79 outbreaks. The Netherlands recently reported one additional outbreak. These numbers indicate a decline in the spread of avian influenza in poultry.
Control Measures and Impact on Trade
In response to the avian influenza outbreaks, various control measures have been implemented. The Department of Agriculture in the Philippines, for instance, temporarily banned the entry of poultry products from the Netherlands due to a reported outbreak. Importation of Dutch wild birds, poultry meat, day-old chicks, eggs, and semen was prohibited to protect the local poultry population.
Trade has also been affected by the avian influenza situation. The Netherlands, one of the major suppliers of meat products to the Philippines, exported 31.3 million kilograms of meat imports to the country in the first half of 2023. However, with the temporary ban, the trade flow has been disrupted, highlighting the economic impact of the disease.
Factors Contributing to the Decline
Several factors have contributed to the decrease in avian influenza cases in European poultry. One factor is the natural epidemic curve, which shows a peak and then a decline in disease incidence. The current trend suggests that the outbreak is reaching its declining phase, which is a positive sign.
Another contributing factor is the development of immunity among wild birds. As more wild birds become exposed to the virus, they build up immunity, reducing the number of cases among the wild bird population. This, in turn, decreases the risk of transmission to domestic poultry.
Furthermore, poultry producers have been implementing stricter biosecurity measures to prevent the introduction and spread of avian influenza in their farms. These measures include proper disinfection, strict control of movements, and monitoring of bird health. Such proactive efforts have helped minimize the risk of disease transmission within poultry farms.
Ongoing Vigilance and Precautions
Despite the improvement in the avian influenza situation, it is essential to remain vigilant and take necessary precautions. The disease can still be present in resident bird populations, and there is a potential risk of reintroduction or new outbreaks. Therefore, it is crucial for poultry farmers and the general public to continue practicing biosecurity measures and report any suspicious cases to the relevant authorities.
The Ministry of Agriculture in France has launched an initiative to investigate disease control specific to free-range and organic farms. While avian influenza is not the primary focus of the initiative, it highlights the importance of biosecurity in these types of poultry production systems.
Impact on Wild Birds
While the situation in domestic poultry is showing signs of improvement, avian influenza continues to affect wild bird populations in Europe. Mass mortalities have been reported among seabirds in Norway, indicating the presence of the virus. Additionally, cases of avian influenza in wild mammals have been confirmed in Northern Ireland.
Germany has reported the highest number of outbreaks in wild birds, followed by France and the Netherlands. The spread of avian influenza in wild birds remains a concern, as it can contribute to the persistence and reintroduction of the virus into poultry farms.
International Cooperation and Reporting
To monitor and control avian influenza, international cooperation and timely reporting are crucial. The World Organisation for Animal Health (WOAH) plays a significant role in coordinating global efforts and disseminating information about disease outbreaks. Countries are encouraged to share data and collaborate on surveillance, prevention, and control measures to mitigate the impact of avian influenza.
Conclusion
The avian influenza situation in European poultry is gradually improving, with a decrease in the number of new cases reported. Control measures, increased immunity among wild birds, and enhanced biosecurity practices have contributed to this positive trend. However, continued vigilance and strict adherence to biosecurity measures are necessary to prevent reintroduction and new outbreaks. International cooperation and timely reporting remain essential in effectively managing avian influenza and safeguarding the poultry industry.
