Sverdlovsk anthrax leak

1979 accidental release of anthrax in the Soviet Union

On 2 April 1979, spores of Bacillus anthracis were accidentally released from a Soviet military research facility in the city of Sverdlovsk, Soviet Union. The ensuing outbreak of the disease resulted in the deaths of at least 68 people, although the exact number of victims remains unknown. The cause of the outbreak was denied for years by the Soviet authorities, which blamed the deaths on consumption of tainted meat from the area, and subcutaneous exposure due to butchers handling the tainted meat. The accident was the first major indication in the Western world that the Soviet Union had embarked upon an offensive programme aimed at the development and large-scale production of biological weapons.
