The present study is part of the EFSA funded project "Risk categorization for Aquatic Animal Health surveillance" (CFP/EFSA/AHAW/2011/03). The aim was to develop a methodology for categorizing (risk ranking) fish farms using farm and disease specific characteristics to develop risk based surveillance for demonstration of disease freedom (EU Directive 2006/88/EC).
Infectious salmon anaemia (ISA) was used as a case disease for Norwegian marine salmon farms, focusing on 4 main pathways of pathogen introduction: movements of live fish and eggs; introduction via water connection; distance-dependent exposure to contaminated fomites as well as contaminated avian or mammalian predators, sea lice and mussels; and distance-independent exposure to fomites including contaminated vehicles and equipment. Literature review and expert opinion were used to gather necessary information regarding risk estimates of various steps in the pathways. The method accounts for uncertainty and variability of input parameters. The output is given as a quantitative score that can be applied by Competent Authorities to risk rank fish farms according to their production routines and exposure to infection. Retrospective data from farms at risk of ISA infection during the period 2008-2009 were used for validation of the method.
We will present and discuss the principle elements of the risk ranking method as well as specific relevance of ISA in marine salmon farms, model outputs, further development of the risk ranking method including application to other aquatic animal diseases, and challenges.
