Interstate Animal Movement Requirements What You Need to Know

When transporting animals, particularly livestock, across state lines, it's crucial to be aware of the varying interstate movement requirements imposed by each destination state. These regulations have long existed to facilitate trade and protect against the spread of diseases. States enforce these requirements through different means, often employing checkpoints at their borders.

Animal owners must always verify the specific requirements and collaborate with their veterinarian well in advance of shipment. This may involve inspections, testing, vaccinations, and proper identification of the animals.

In most cases, a certificate of veterinary inspection (CVI), also known as a health certificate, is necessary. This document must be issued by a licensed veterinarian who is accredited by the United States Department of Agriculture (USDA), certifying that the animals meet the entry requirements of the destination state.

Accurate completion and issue of CVIs within the designated timeframe are crucial for facilitating movement. Entry requirements can change, especially during disease outbreaks, so animal owners and veterinarians must verify updated requirements before each shipment. Animals affected by infectious, contagious, or communicable diseases are not eligible for CVIs.

The Texas Animal Health Commission (TAHC) has recently reinstated livestock checkpoints at state borders, including the Oklahoma-Texas border. All livestock transport vehicles, regardless of whether they are loaded or empty, are required to stop at these checkpoints. Entry requirements and associated documentation are thoroughly reviewed at these checkpoints.

Entry requirements for animal movement vary depending on the purpose, and exceptions may apply. For instance, Texas livestock transported to an Oklahoma veterinary clinic do not require a CVI or permit to return to Texas. However, it is advisable for animal owners to have documentation of the veterinary visit for checkpoints upon re-entry.

Currently, Oklahoma livestock being transported to a Texas veterinary clinic for services or care do not need a CVI, but producers must contact the TAHC to obtain a permit at the inspection checkpoint.

Staying informed about interstate animal movement regulations, adhering to checkpoints, and complying with entry requirements are vital to ensure smooth and lawful livestock transportation while mitigating the risk of disease transmission.
