What agency or organization is responsible for regulating the shipping of animals to foreign countries?

The correct answer is the Department of Agriculture. This agency has the authority to establish regulations and oversee the shipping of animals to foreign countries to ensure that animal health standards are met. These regulations are crucial for preventing the spread of diseases that can affect both animal and human health. The Department of Agriculture works closely with international partners to harmonize standards and facilitate safe trade in animals and animal products.

The other options, while important in the global health context, do not have the specific mandate to regulate shipping animals. The World Health Organization focuses on public health issues, including disease prevention and health promotion globally. The United Nations oversees a wide range of international issues, including humanitarian efforts and global governance but does not have jurisdiction over animal shipping regulations. The Centers for Disease Control and Prevention primarily focuses on human health, particularly disease control and prevention within the United States, and does not manage the international trade of animals.
