Due to the changing conditions of animal production in Switzerland the
demand for scientificly based animal health information has increased
during the last years. It has become a central element in animal heal
th policy making. National animal health surveillance systems include
methods for data collection, analyses, interpretation and information
distribution. The current Swiss surveillance systems are presented. In
the future, these systems should be more integrated in order to make
better use of the available data. The project ''Systems for the record
ing of animal health in Switzerland'' (SysET) is a proposal how a comp
rehensive animal data base could be developed.
