Which term describes vaccines, antisera, toxoids, and diagnostic kits regulated by USDA?

• A. Veterinary biologics
• B. Biologicals
• C. Medical devices
• D. Pharmaceuticals

Answer: (A)

Veterinary biologics are the biological products used in animals, and the USDA regulates them to ensure safety, purity, potency, and effectiveness. Vaccines, antisera, toxoids, and diagnostic kits fall into this category because they are derived from living sources or rely on biological processes and are used to prevent, diagnose, or treat animal diseases. The USDA—through its APHIS Center for Veterinary Biologics—licenses producers and oversees the distribution of these products to safeguard animal health. This set is distinct from broader terms like biologicals in general (which can include human products), medical devices (FDA-regulated), or pharmaceuticals (typically FDA-regulated in a broader sense). So, the precise term for these USDA-regulated animal health products is veterinary biologics.
