Which of the following is NOT responsible for the disposition of animal by-products at U.S. ports of entry?

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

Answer: (C)

Disposing of animal by-products at U.S. ports is handled by agencies with regulatory authority over animal health and border enforcement. The unit within USDA APHIS that focuses on animal health and the entry of animal-related materials makes the key decisions about entry, required treatments, quarantines, or destruction. The U.S. Customs Service enforces import requirements at the border and works with that health agency to ensure compliance. The APHIS Plant Protection and Quarantine division handles plant pests and plant products, not animal by-products, so its role here is minimal. The Foreign Agricultural Service, on the other hand, concentrates on international agriculture trade policy and market development rather than the on-site health and disposition decisions at ports. Therefore, the Foreign Agricultural Service is not responsible for the disposition of animal by-products at U.S. ports of entry.
