Which agency restricts the domestic sale or movement of turtles under four inches in length?

• A. FDA
• B. CDC
• C. USDA
• D. EPA

Answer: (A)

The question tests understanding of which agency regulates the risk of disease transmission from pet reptiles by controlling how they’re sold or moved. Small turtles—those with a shell length under four inches—are restricted because they pose a higher risk of spreading Salmonella to people, especially children who handle them. The regulation to prevent this is enforced by the agency that oversees interstate commerce for consumer products, including live animals offered as pets. That agency restricted the sale or movement of these tiny turtles to reduce human illness.

The other agencies don’t carry this specific sales/movement restriction: the CDC focuses on disease surveillance and public health guidance, not the regulatory control of animal commerce; the USDA handles broader animal health and welfare in agriculture but not this particular consumer-sale rule; the EPA deals with environmental protection and pesticides.
