Which U.S. agency is primarily responsible for protecting against foreign animal diseases?

The United States Department of Agriculture-Animal and Plant Health Inspection Service (USDA-APHIS) is the primary agency responsible for protecting against foreign animal diseases. This agency plays a crucial role in safeguarding animal health in the U.S. by monitoring and controlling diseases that can affect livestock and wildlife, especially those diseases that may be imported from other countries.

USDA-APHIS conducts inspections at borders to prevent the entry of diseases, implements surveillance programs to monitor animal populations for any outbreaks, and collaborates with international partners to respond to emerging threats. Their focus is on the health of animals and plants, ensuring that they are free from diseases that could impact the food supply, agriculture, and biodiversity.

In contrast, the Centers for Disease Control and Prevention (CDC) primarily focuses on human health and disease prevention. The Food and Drug Administration (FDA) regulates food safety, pharmaceuticals, and medical devices but is not directly responsible for animal disease control. The Environmental Protection Agency (EPA) deals with human health and the environment but does not specialize in animal health issues. Thus, USDA-APHIS is best aligned with the responsibilities of protecting against foreign animal diseases.
