Currently, livestock sector accounts for nearly half of global agricultural economy. Recent animal health emergencies have highlighted the vulnerability of pecuary industry to epizootic episodes caused by infectious diseases. The impact of animal diseases on health and human welfare is being increasingly considered. Sixty percent of emerging diseases that affect humans are zoonoses, most of them (about 75%) originate from wildlife. Many of those diseases are common to productive domestic animals, due to the multiple interrelationships and the ability of many microorganisms to mutate and to colonize new hosts.
Therefore, direct impact of Transboundary Animal Diseases in agriculture and public health, constitute a serious limitation to export living animals and their products, as well for international trade. Moreover, seriously compromised food security and causing a high socioeconomic impact on agricultural exporting nations.
During the next 15 to 20 years, the demand for livestock products is considering to double, a process called "Livestock Revolution" driven by changing a cereal-based diet to a diet based on proteins. It is estimated that in 2015, 60% of meat and 52% of the milk, will be consumed in
developing countries. The increasing globalization markets, facilitates the introduction of transboundary animal disease.
