The Texas Animal Health Commission’s mission is to protect agricultural animals (livestock, exotic livestock, domestic fowl, and exotic fowl) from diseases recognized as communicable by the veterinary profession. To achieve its mission, the Commission makes and enforces rules concerning testing, entry into Texas, movement, inspection, and recordkeeping requirements.

Read more about TAHC’s statutory authority (detailed in Title 6, Subtitle C. Control of Animal Diseases and Pests, Chapters 161 through 168, of the Texas Agriculture Code).

Anyone with information concerning a suspected violation of TAHC rules/requirements is encouraged to file a complaint according to the process described below.

Types of Complaints Under TAHC Jurisdiction

The Commission will evaluate the following types of complaints from the public:

  • Entry requirements
    • Agricultural animals entering the state of Texas are subject to health / testing requirements. Generally agricultural animals entering Texas must be accompanied by a Certificate of Veterinary Inspection or Health Certificate ("CVI") issued by a veterinarian within 30 to 45 days prior to entry. These CVIs are available from TAHC to veterinarians in Texas. Most entry requirements are found in Chapter 51 of the Commission’s rules.
  • Testing requirements for the sale or transfer of ownership
    • Equine animals must have a negative Equine Infectious Anemia (EIA, "Coggins") test upon change of ownership. The results must be accompanied by a completed VS Form 10-11 (official Equine Infectious Anemia Laboratory Test document) for each horse.
    • All breeding swine must have negative brucellosis and pseudorabies (PRV) prior to change of ownership.
  • Movement restrictions
    • Animals that have been exposed to a disease may be restricted from movement to other premises. TAHC will issue a "Hold Order" to restrict movement of animals suspected of exposure to a disease. A "Quarantine" is used to restrict movement of known positive animals.
  • Other testing requirements
    • Equine animals that participate in shows, fairs, exhibitions or assemblies, such as rodeos, barrel racing or trail rides must have a Coggins test within the last 12 months.
    • Roping steers from Mexico with a "M" Brand on their right hip must be accompanied by an annual test for Tuberculosis.
