Bovine BR region application v4

APHIS Bovine Brucellosis Evaluation Questionnaire

Introduction: A representative of the central competent veterinary authority of any country or countries may request that the Animal and Plant Health Inspection Services (APHIS) classify a region for bovine brucellosis (Brucella abortus). A region is defined as a geographical land area identifiable by geological, political, or surveyed land boundaries. Examples include (1) an entire country; (2) part of a country; (3) parts of several countries; and (4) a group of countries. The borders of a region must be clearly defined and the entire region must be accessible to both national veterinary authorities and APHIS personnel.

Title 9, Code of Federal Regulations, section 93.441 (9 CFR 93.441) describes the process for requesting regional classification for brucellosis. This document clarifies the information required for APHIS to evaluate a region. APHIS will conduct a site visit to verify and complement the information provided. Any resulting regulatory action will reflect the conclusions of the evaluation. The evaluation methodology and criteria are further described in APHIS Evaluation Procedures for Bovine Brucellosis: Classification of Foreign Regions.

To facilitate the evaluation process, please submit all information in English.
