Plum Island Animal Disease Center

Plum Island Animal Disease Center of New York (PIADCNY) is a United States federal research facility dedicated to the study of animal diseases. It is part of the DHS Directorate for Science and Technology.

Since 1954, the center has had the goal of protecting America's livestock from animal diseases. During the Cold War a secret biological weapons program targeting livestock was conducted at the site, although it had slowly declined through the end of the century. After the September 11 attacks in 2001, Plum Island renewed its research into biological weapons. This program has been for many years the subject of controversy.
