California Animal Blood Banks Program

As a result of increased specialization in veterinary medicine, the demand for animal blood products has risen dramatically. A safe and adequate supply of blood and blood component products for transfusion is vital to animal health. Commercial blood banks for animals produce and sell blood and blood component products, increasing the supply available for transfusions. The CDFA Animal Blood Banks program defines current standards of care and practice for veterinary blood banks and works to ensure that animal blood and blood component products sold in California are efficacious and safe.

Historically, California required commercial blood banks for animals to be closed-colony establishments. On January 1, 2022, Assembly Bill 1282, the California Pet Blood Bank Modernization Act, went into effect. This law aims to address the shortage of animal blood available for veterinary transfusion medicine in California and transition the state from closed-colony blood banks to community blood banks.

California Food and Agricultural Code (FAC) Division 5, Chapter 1.5 (Commercial Blood Banks for Animals and Biologics) and California Business and Professions Code (BPC) Division 2, Chapter 11, Article 7 (Community Blood Banks for Animals) are the State’s legal authority for enforcing state law and regulations pertinent to animal blood banks.


  • February 27, 2023: The Animal Blood Banking Guidance Document is now available. The document was created in conjunction with the Veterinary Medical Board, technical experts, and stakeholders. It is designed to give veterinarians clear, accurate, and concise information regarding best management practices for operating animal blood banks. It includes information in all the following areas:
    • Animal donor qualification, selection, and screening
    • Bloodborne pathogen testing
    • Safe blood products handling, processing, labeling, and storage
  • January 1, 2022: Importation and sale of canine blood and blood component products from out-of-state sources shall only be permitted from community blood banks (FAC 9252 (b)). CDFA will discontinue its licensing program for commercial blood banks for animals that produce canine blood and blood component products sourced from captive closed-colony dogs within 18 months of making a finding that community blood banks sold an annual amount of canine blood in California that equals or exceeds the annual amount closed-colony blood banks sold in four consecutive quarters. This will be announced on this website.
