Animal Disease Traceability (ADT)

Animal Disease Traceability (ADT) is a cooperative program that is jointly funded and administered by the United States Department of Agriculture (USDA) Animal Plant Health Inspection Service (APHIS) and the Texas Animal Health Commission.

Animal disease traceability, knowing where and when diseased and at-risk animals are or have been, is important to ensuring a rapid response when animal disease events take place. Although animal disease traceability does not prevent disease, an efficient and accurate traceability system reduces the number of animals and response time involved in a disease investigation; which, in turn, reduces the economic impact on owners and affected communities.
