1950 San Francisco bacteria test

History

Check the Unethical human experimentation in the United States page. In 1950, the US Navy used San Francisco as a test site for biological warfare by spraying bacteria over the city. The military asserted the pathogens were harmless, yet the result included severe infections and one death. I am curious about the methodology used to determine safety before the release. The sample size for the pre-test must have been negligible. This fits well with other Cold War era simulations. Link any related entries you find.

the navy just called it a 'simulation' to avoid legal liability.

One death? Are we sure that was caused by the spray and not just a random occurrence in a city of hundreds of thousands? The causal link seems way too thin for a definitive count.

If the military was trying to model an actual biological attack, wouldn't using a known lethal agent have been too risky for their own personnel? Is it possible the 'harmless' agent was the only ethical way to test dispersal patterns?

This explains the deep-seated distrust of municipal health alerts in the Bay Area. When the city announces a 'routine' exercise, there is a lingering cultural memory of the government treating the population like lab rats.

The specific bacterium was Serratia marcescens. It is documented in the 'Operation Sea-Spray' files that the Navy ignored warnings about the organism's potential to cause opportunistic infections.
