Why use outcome based surveillance ?

Due to increasing demand for more cost-effective surveillance programmes and in order to comply with requirements in the European Council Directive 2006/88/EC, outcome-based surveillance has been applied to a recently implemented programme that aims to document freedom from viral haemorrhagic septicaemia (VHS) in farmed Atlantic salmon. In Norway, the surveillance is based on a general health surveillance system in fish farms that has been carried out since the early 1990s, according to a legal framework, by authorised veterinarians and fish health biologists working independently or as industry owned fish health services (FHS). The frequency of FHS visits to the farm is six per year as a minimum, and is based on assessment of clinical findings and the observation of gross pathology, mortality and other relevant production data, and the risk associated with newly introduced fish.
