Shrimp is an important commodity in international trade accounting for 15 % in terms of value of internationally traded seafood products which reached $102.00 billion in 2008. Aquaculture contributes to over 50 % of global shrimp production. One of the major constraints faced by shrimp aquaculture is the loss due to viral diseases like white spot syndrome, yellow head disease, and Taura syndrome. There are several examples of global spread of shrimp diseases due to importation of live shrimp for aquaculture. Though millions of tonnes of frozen or processed shrimp have been traded internationally during the last two decades despite prevalence of viral diseases in shrimp producing areas in Asia and the Americas, there is no evidence of diseases having been transmitted through shrimp imported for human consumption. The guidelines developed by the World Animal Health Organisation for movement of live animals for aquaculture, frozen crustaceans for human consumption, and the regulations implemented by some shrimp importing regions in the world are reviewed.
