This FBI file relates to bacteriological warfare. It contains investigative information gathered over several decades. Significant portions of the file have been redacted or entirely withheld due to security or privacy concerns, using exemptions under the Freedom of Information Act (FOIA).
Reports detail the use of bacteriological weapons in the Korean War, allegedly by U.S. forces, as claimed by various organizations in China and North Korea. Chinese trade unions and women’s organizations made appeals to international bodies to denounce and act against these actions .
Some sections include accounts of individuals suspected of being involved in subversive activities or espionage. For instance, John T. Brady alleged bacteriological warfare conducted in Illinois, raising concerns about potential German agents during World War II. Further investigation found Brady had a neurotic obsession with disease and that his claims were largely unfounded .
