Abstract
Infectious pancreatic necrosis (IPN) was assessed according to the criteria of the Animal Health Law (AHL), in particular, the criteria of Article 7 on disease profile and impacts, Article 5 on its eligibility to be listed, Annex IV for its categorisation according to disease prevention and control rules as in Article 9, and Article 8 for listing animal species related to IPN. The assessment was performed following a methodology previously published. The outcome reported is the median of the probability ranges provided by the experts, which indicates whether each criterion is fulfilled (lower bound ≥ 66%) or not (upper bound ≤ 33%), or whether there is uncertainty about fulfilment. Reasoning points are reported for criteria with an uncertain outcome. According to the assessment here performed, it is uncertain whether IPN can be considered eligible to be listed for Union intervention according to Article 5 of the AHL (50-90% probability). According to the criteria in Annex IV, for the purpose of categorisation related to the level of prevention and control as in Article 9 of the AHL, the AHAW Panel concluded that IPN does not meet the criteria in Section 1 (Category A; 0-1% probability of meeting the criteria) and it is uncertain whether it meets the criteria in Sections 2, 3, 4 and 5 (Categories B, C, D and E; 33-66%, 33-66%, 50-90% and 50-99% probability of meeting the criteria, respectively). The animal species to be listed for IPN according to Article 8 criteria are provided.

Abstract
Salmon fish farmers face remarkable problems in fish rearing and handling due to the spread of disease by infectious pancreatic necrosis virus (IPNV). Therefore, we developed a straightforward and sensitive technique to detect IPNV-based on recombinant human apoferritin heavy chain (hAFN-H) protein nanoparticles. In this study, the 24 subunits of the hAFN-H were genetically modified to express 6×His-tag and protein-G at their C-terminal site using Escherichia coli. We thus achieved a two-step signal amplifying strategy that utilizes a recombinant hAFN-H nanoprobe having a protein-G-binding site that targets the Fc region of monoclonal antibodies and a 6×His-tag that actively interacts with the functionalized Ni-NTA derivatives. In this study, we report a considerable advancement in magnetic bead-based detection systems that use Ni-NTA-Atto 550, reliably exhibiting detection limits of 1.02 TCID50/mL (50% tissue culture infective dose). Additionally, we propose a lateral flow chip-based detection method that uses the hAFN-H surface functionalized with 5 nm of the Ni-NTA-nanogold complex as a nanoprobe; the limit of detection towards IPNV was 0.88 TCID50/mL. The detection of IPNV by this recombinant hAFN-H nanoprobe was linear to virus titers in the range of 101-103 TCID50/mL.
