The 1984 Rajneeshee bioterror attack was the food poisoning of 751 individuals in The Dalles, Oregon, United States, through the deliberate contamination of salad bars at ten local restaurants with salmonella. A leading group of followers of Bhagwan Shree Rajneesh (later known as Osho) had hoped to incapacitate the voting population of the city so that their own candidates would win the 1984 Wasco County elections. The incident was the first and single largest bioterrorist attack in United States history.
