In 1984, The Dalles was the scene of a bioterrorist incident launched by members of the Rajneesh Movement in an attempt to gain control of the local government of Wasco County. Salmonella placed in ten restaurants resulted in 751 cases of Salmonellosis. It was the first known bioterrorism attack of the 20th century in the United States. The circumstances of the attack are documented in an American Medical Association article (JAMA Vol 278, No 5, page 389, 6 Aug 1997).
