• D. All of the above are true.

Answer: (A)

A foreign animal disease diagnostician is a veterinarian who has completed specialized training at the Foreign Animal Disease Diagnostics Laboratory (FADDL) on Plum Island, New York, to recognize and diagnose exotic animal diseases. When a foreign animal disease is suspected, these trained individuals are the designated veterinarians who should collect and submit laboratory samples, ensuring proper biosafety, chain of custody, and timely submission to the diagnostic network. This precise training location and the defined sampling responsibility are what make this description the best fit. Other statements expand roles or staffing in ways that aren’t universally accurate or central to the FADD designation.
