Last week, the U.S. House of Representatives quietly passed a bill requiring the Inspector General of the Department of Defense (DoD) to conduct a review into whether the Pentagon experimented with ticks and other blood-sucking insects for use as biological weapons between 1950 and 1975. If the Inspector General finds that such experiments occurred, then, according to the bill, they must provide the House and Senate Armed Services committees with a report on the scope of the research and whether any ticks or insects used in such experiments were released outside of any laboratory by accident or experiment design," potentially leading to the spread of diseases such as Lyme. The amendment was put forward by Rep. Chris Smith, a Republican from New Jersey, who was "inspired" by several books and articles claiming that the U.S. government had conducted research at facilities such as Fort Detrick, Maryland, and Plum Island, New York, for this purpose. One of the books that Smith refers to - called Bitten: The Secret History of Lyme Disease and Biological Weapons ... features interviews with late Swiss-born scientist Willy Burgdorfer - the man credited with discovering the bacterial pathogen that causes Lyme disease - who once worked for the DoD as a bioweapons specialist. "Those interviews ... suggest that he and other bioweapons specialists stuffed ticks with pathogens to cause severe disability, disease - even death - to potential enemies," Smith said.
