Mappingthe ‘data sources’ on animal diseases,in each European Union (EU) Member State, is one of the activities of EFSA's SIGMA1,2 project. The aim of this activity is to identify the central competent authorities responsible for managing the data on animal diseases and animal populations in each Member State. Initially EFSA is focusing on three diseases (on which EFSA is currently working): African swine fever, avian influenza and lumpy skin disease; and on the corresponding affected animal populations: swine, poultry and bovines, respectively. This technical report presents the results of the implementation of the above activity for Netherlands and provides information on the authorities which constitute the data sources on animal diseases within the country. It also includes the ‘Country Card’, that depicts the central competent authorities responsible for the data on animal diseases (data on outbreaks, surveillance activities and laboratory results) and on animal populations (bovines, swine, poultry) in Netherlands.It has been generated based on the replies submitted by Netherlands via the EUSurvey questionnaire and on the clarifications provided subsequently. The Ministry of Economic Affairs and Climate and the Ministry of Agriculture Nature and Food Quality are the central sources of data related to animal diseases and to animal populations in Netherlands. Within these authorities, different Divisions and Departments are involved with different types of data.
