Cold War bioweapons test exposed millions in San Francisco Bay Area
Original: The secret Cold War bioweapons test that exposed millions in the Bay Area
A declassified Cold War experiment known as Operation Sea-Spray is drawing renewed attention: in 1950 the US Navy sprayed bacterial aerosols, including Serratia marcescens, over San Francisco from ships offshore to study how a biological attack might spread. The tests exposed roughly 800,000 residents without their knowledge and are linked to rare infections afterward. Readers are debating government secrecy, consent and the ethics of testing on civilians.
Why now: Ongoing concerns about government secrecy and public health make the declassified tests resonate with readers.
