5. import risk assessment(English)

   • application of risk analysis to the spread of disease with international trade in animals and their products has been largely driven by the Sanitary and Phytosanitary (SPS) agreement of the WTO. The IRA standard established by the World Organization for Animal Health (OIE), and associated guidance, should meet the needs of the SPS agreement. The use of scenario trees is the core modelling approach used to represent the steps necessary for the hazard to occur. There is scope to elaborate scenario trees for commodity IRA so that the quantity of hazard at each step is assessed, which is crucial to the likelihood of establishment. Standards and guidance should serve the principle of science-based decision-making
