Foot-and-mouth disease: current world situation.

Foot-and-mouth disease (FMD) has increased in significance as a major constraint to international trade in live animals and animal products as the World Trade Organization agreements remove other obstructions. A consequence will be reluctance to immediately declare the presence of FMD if it is thought possible to quickly eliminate its presence and so avoid trade embargoes. This will predispose to spread of disease between trading partners. In addition, as countries tend to increase the requirements for testing and certification of imported animals with the objective of reducing the risk of importing disease, the increased costs and delays that this involves will encourage the illegal trade and therefore have the converse result.
