Which port-of-entry regulation addresses the disposition of animal by-products?

• A. USDA APHIS Plant Protection and Quarantine
• B. Foreign Agriculture Service
• C. U.S. Customs Service
• D. USDA APHIS Veterinary Services

Answer: (D)

Disposal of animal by-products at ports of entry is governed by the animal health regulatory arm of the USDA. Veterinary Services within APHIS handles import health standards for animals and animal-origin materials, including the rules for how by-products must be disposed of to prevent disease spread. They oversee inspections, health certificates, and the procedures for rendering, incineration, or other permitted disposal methods for shipments arriving at the border. While other agencies may touch border entry in broader ways, they do not set or enforce the specific disposition rules for animal by-products; Plant Protection and Quarantine focuses on plants and pests, the Foreign Agricultural Service handles trade policy, and U.S. Customs enforces border control but relies on APHIS VS for the health-related requirements.
