Which item is listed in the CITES list as prohibited by FDA and endangered species?

• A. Xi Jiao
• B. Chuan Shan Jia
• C. Hu Gu
• D. Hou Zao

Answer: (A)

Rhinoceros horn is the classic example of a wildlife product restricted by both international and U.S. regulation due to the species’ critical status. Rhinoceros horn is listed on CITES Appendix I, which means commercial international trade is essentially prohibited to protect the species from extinction. The FDA enforces import and sale restrictions in the United States for products containing rhinoceros horn, reflecting that endangered status. That combination—CITES Appendix I listing plus FDA prohibition—is why Xi Jiao (rhinoceros horn) is the correct choice. Pangolin scales and tiger bone are also tightly regulated and from endangered species, but this item most directly illustrates the FDA-prohibited status tied to an Appendix I wildlife product.
