© 2018 Elsevier B.V. In the present study a risk assessment tool was developed for improving biosecurity on pig farms as part of a voluntary program for PRRS control on farms located in NE Spain. The arrival of the PRRS virus through different routes was estimated based on their likelihood of harbouring the virus and the estimation of a score for the probability of introduction. For each possible route of introduction or spread within the herds, single or combined biosecurity measures aimed at reducing the probability of PRRS virus transmission were selected. Results showed that the scores for the probability of introduction and spreading were related to a highly variable application of biosecurity measures. The tool developed in the present study may be suitable for identifying where efforts should be focused in biosecurity actions forming part of disease control programs.
