The Regionalization Evaluation Services (RES) evaluates the animal health status of foreign regions (zones) and the risk of disease introduction via commodities for import into the United States. A region is a geographical land area identifiable by geological, political, or surveyed land boundaries that contains an animal subpopulation with a distinct animal health status. RES also assists in the coordination of data to support regionalization of the United States for export purposes.
RES follows a science- and risk-based approach that is consistent with APHIS obligations under international trade agreements. When evaluating the animal health status of a foreign region, RES Staff:
RES risk assessments for regions requesting APHIS recognition of disease freedom or a commodity-based evaluation (if the region cannot be considered free of the disease) typically follow an 8-factor framework defined in title 9, Code of Federal Regulations, part 92.2(b). These factors are:
However, a region may be considered historically free of a disease if it has not occurred in domestic livestock in the region for at least 25 years (if ever) or in wildlife for at least 10 years. RES conducts historically free evaluations according to a 6-factor format defined in title 9, Code of Federal Regulations, part 92.2(c). These factors are:
The RES process for conducting regionalization evaluations is further described in this document:
A list of regions that have requested APHIS evaluation of their animal health status is available here:
English translations of all supporting materials must be submitted. Submission of the information in electronic format can facilitate the review. *All documents submitted will be made available to the public, so please do not submit confidential information unless it is clearly identified as confidential.
If you wish to submit a request for a standard regionalization evaluation (not qualified for consideration as historically-free), please follow the format described in this document:
If you wish to submit a request for evaluation as a historically-free region, please follow this format:
For information required for countries requesting recognition please refer to OIE Terrestrial Animal Health Code, Articles 1.6.5
