Animal Disease Notification System (ADNS)

Animal Disease Notification System (ADNS)

What is ADNS?

ADNS is a notification system designed to register and document the evolution of the situation of important infectious animal diseases. It is a management tool that ensures immediate notification of alert messages as well as detailed information about outbreaks of these animal diseases in the countries that are connected to the application. This permits immediate access to information about contagious animal disease outbreaks and ensures implementation of early warning which enables for a prompt response for controlling the epidemiological situation. This has a direct impact on trade of live animals and their products both for the internal market as well as for international trade with third countries.

While ADNS is a system not directly related with food safety, it has an impact on public health in relation to all zoonotic diseases within its scope.


The operational objective of the system is to ensure rapid exchange of information between the competent authorities responsible for animal health in each EU country and the Commission on outbreaks of contagious animal diseases.

The system allows the coordination and monitoring of outbreaks of contagious animal diseases and enables EU countries and Commission services to take immediate measures to prevent the spread of the diseases in question.

Legal basis

Council Directive 82/894/EEC (as last amended by Commission Implementing Decision 2012/737/EU ) provides the legal basis for ADNS. This Directive makes it compulsory for the EU countries to notify primary and secondary outbreaks of listed infectious animal diseases such as Foot and Mouth Disease, Classical swine fever, Newcastle disease, etc. In the same Directive are laid down the rules about the procedures for notification, in particular the information to be sent and the time limits for notification.

Commission Decision 2005/176/EC (repealing Decision 2000/807/EC) lays down the codified form and the codes for the notification of these contagious animal diseases. The list of Countries provided by this Decision includes the EU countries and Andorra, Faroe Islands, Norway and Switzerland.


The EU countries and the other countries connected to the application are responsible for supplying ADNS with the necessary information. Two types of outbreak exist:

  • Primary outbreak: an outbreak of a contagious animal disease not epizootiologically linked with a previous outbreak in a region or the first outbreak in a previously unaffected region of a Member State. For this kind of outbreak all members need to be immediately informed. Council Directive 82/894/EEC provides that the notification must be sent within 24 hours of confirmation of the outbreak. The notification can be inserted directly into the ADNS system via the internet or sent by a structured e-mail to the Commission and the information is automatically inserted into the ADNS system. Once a primary outbreak is entered into the system, an e-mail is sent to all the countries connected to the application.
  • Secondary outbreak: an outbreak following a primary outbreak in an already infected region. For the secondary outbreak, the notification must be sent at least on the first working day of each week.

A weekly (every Friday at 3.30pm) e-mail message is sent to all the ADNS members summarising all primary and secondary outbreaks that have been entered into the system.

Commission Management

The designated competent authorities in an EU country enters information on outbreaks into the ADNS. Information on primaries is automatically sent to all EU countries and the Commission.

The Commission correlates data and transmits the information on primaries and secondary outbreaks to the veterinary headquarters of the EU countries every week.

The veterinary authorities in EU countries assess the risk. The risk management is shared between EU countries and Commission services. The action of the Commission consists in the adoption of Decisions eventually through the Committee procedure (Standing Committee on the Food Chain and Animal Health).

However, when the first outbreak of a contagious animal disease occurs (i.e. Classical Swine Fever or Foot-and-Mouth Disease), the situation has to be considered extremely urgent. In some cases, due to the particular high-speed diffusion of some diseases, the reaction has to be immediate. For this reason 24 hour (round the clock) control on these notifications is needed. In view of this, the Head of Unit in DG SANTE can be contacted via GSM/mobile telephone and in case of disease outbreaks, the Head of Unit and/or other colleagues can then come to the office to cover the epidemic event.

The presence of expert personnel with knowledge of veterinary legislation on animal health, contagious animal diseases and epidemiology is also needed to manage this kind of emergency situation.

Animal disease information from EU countries

Detailed information on each outbreak in an EU country of an infectious disease in animals, listed in Annex I of Council Directive 82/894/EC, is sent by the EU countries to the European Commission via the Animal Disease Notification System (ADNS).

A summary of the number of outbreaks and the date of the last outbreak notified to the European Union* is given in a table for the current year. It is updated on a regular basis. Overviews for the previous years can be found in the right hand side RELATED DOCUMENTS box.

*NB: The table and maps only reflect the situation as notified by the countries on the list.

Annual reports also have been prepared showing the disease situation in different years:

Diseases reported by the EU countries

1. Avian influenza

2. Low pathogenic avian influenza

3. Newcastle disease

4. Bluetongue
