What regulatory body monitors dogs from countries with endemic screwworms?

The Department of Agriculture, specifically the Animal and Plant Health Inspection Service (APHIS), is responsible for monitoring and regulating animals, including dogs, from countries where screwworms are endemic. This is crucial for preventing the introduction and spread of this harmful pest into the United States. APHIS has established policies and protocols to protect the agricultural and public health by ensuring that animals coming from affected regions are properly inspected and treated if necessary.

The other regulatory bodies listed do not have the specific mandate or focus on animal health in relation to screwworms. The World Health Organization primarily deals with human health issues; the Department of Homeland Security focuses on national security rather than agricultural health; and the Department of Defense does not engage in the monitoring of animal health related to pests and diseases. Therefore, APHIS is uniquely positioned and equipped to handle these specific concerns regarding livestock and pet safety from imported animals.
