摘要
The growth in penaeid shrimp aquaculture has been mirrored by the emergence of a number of serious diseases, some of which (e.g. white spot syndrome virus - WSSV) spread rapidly across the globe through movement of infected stock. The World Organisation for Animal Health (OIE) lists six penaeid shrimp pathogens of which three are notifiable in the EU: WSSV (listed as non-exotic to the EU), Taura syndrome virus (TSV) and yellow head disease (YHD) (both listed as exotic). EU Member States (MS) must determine a status for non-exotic diseases (e.g. disease free, unknown, infected). In developing a policy for WSSV, import risk analysis (IRA) can be used to systematically assess the risks of introduction and justify risk mitigation to maintain freedom. OIE guidelines recommend that countries assess the risk of disease introduction via commodities, not listed by the OIE as safe, and apply sanitary measures if necessary. The sanitary measures necessary to maintain freedom from WSSV may not be compatible with current EU animal health legislation. The recent revision by OIE of products listed as safe for international trade strengthens the case for the risks of TSV and YHD introduction into the EU to be assessed. Freedom from WSSV is an important criterion for the development of shrimp aquaculture in the EU. However, in developing disease control policy, governments need to balance the potentially competing interests of all stakeholders, including consumers. Thus economic modelling of the impact of possible sanitary measures on consumer prices of imported products is needed to support decision making. The creation of disease free compartments and post-import risk mitigation for commodities may create the conditions conducive to the development of shrimp aquaculture whilst minimising the costs of maintaining disease freedom.
