In the framework of the EU4Health Programme, the European Commission has allocated specific resources for Member States for setting up a coordinated surveillance system under the One Health approach for cross‐border pathogens that threaten the Union (CP‐g‐22‐04.01 Direct grants to Member States’ authorities). This initiative required the development of surveillance plan proposal for early detection of zoonotic pathogens in animals and the environment. This report summarized the preparatory work undertaken for the development of surveillance plan proposals for early detection of zoonotic pathogens in pigs and poultry. Two diseases were in the focus of this work, namely Hepatitis E and Influenza in Swine. Four so‐called surveillance activity cards were developed for Hepatitis E and one surveillance activity card for Influenza in Swine. These surveillance plan proposals serve the purpose of outlining scientifically sound surveillance options for zoonotic pathogens for review and further development by experts of the EFSA Working Group on One Health surveillance.
