Building 257
Building 257, also known as Lab 257, was a United States biological warfare research laboratory located at Fort Terry on Plum Island, New York. Originally intended for munitions storage, the facility researched anti-animal biological agents beginning in 1952 under the United States Army. Biological warfare research continued in the building under the United States Department of Agriculture (USDA) until a new laboratory was completed. History. Building No. 257 at Fort Terry, on Plum Island near Long Island, New York, was completed around 1911. The original purpose of the building was to store weapons, such as mines, and  the structure was designated the Combined Torpedo Storehouse and Cable Tanks building. Fort Terry went through a period of activations and deactivations through World War II until the U.S. Army Chemical Corps took over the facility in 1952 for use in anti-animal biological warfare (BW) research. The Chemical Corps planned a laboratory for the fort, to be housed in Building 257. The conversion of Fort Terry to a BW facility required the remodeling of Building 257 and other structures. As work neared completion on the lab and other facilities in the spring of 1954 the mission of Fort Terry  changed. Construction was completed on the facilities on May 26, 1954, but the post was transferred to the USDA before the military could utilize the new laboratory facilities. Fort Terry was officially transferred to the USDA on July 1, 1954, at the time scientists from the Bureau of Animal Industry were already working in Building 257. Construction on a new lab facility, known as Building 101, also began about this time but was not completed until September 1956. A modernization program in 1977 aimed to update both Building 257 and Building 101, but the program was canceled in 1979 because  of construction contract irregularities. Plum Island facilities were essentially unchanged until a new modernization began in 1990. Two-thirds of the laboratory facilities inside Building 101 were renovated and operations in Building 257 were consolidated into Building 101. According to a United States Department of Homeland Security spokesperson in 2004, Building 257 was closed in 1995 and poses no health hazard. Research. The original anti-animal BW mission was "to establish and pursue a program of research and development of certain anti-animal (BW) agents". By August 1954 animals occupied holding areas at Plum Island and research was ongoing within  Building 257. Scientists worked with "hot viruses" in the building, known simply as Lab 257 at this point, on animals and in petri dishes. Work was conducted through gloveboxes: steel, windowed boxes outfitted with glove inserts for experiments inside the contained box. The USDA facility, known as the Plum Island Animal Disease Center, continued work on biological warfare research until the U.S. program was ended by Richard Nixon in 1969. The bio-weapons research at Building 257 and Fort Terry was shrouded in aura of mystery and secrecy. The existence of biological warfare experiments on Plum Island was denied for  several decades by the U.S. government. In 1993 "Newsday" unearthed documents proving otherwise. Discredited conspiracy theories. Conspiracy theories have spread that falsely allege Lyme disease, first documented in nearby Lyme, CT, was a bioweapon that originated at Plum Island laboratory. A discredited 2004 book entitled "Lab 257: The Disturbing Story of the Government's Secret Plum Island Germ Laboratory" fueled the conspiracy theories. Archived specimens show that Lyme disease was endemic well before the establishment of Plum Island laboratory. Additionally, Lyme disease was never a topic of research at Plum Island, according to the US Department of Homeland Security and  Department of Agriculture.
