(NaturalNews) It is perhaps one of the oldest of all conspiracies: Your government is conducting a wide range of experimental research on various populations without their knowledge, much less permission – research that has come with consequences to health and well-being.

For its part, Natural News has regularly reported on the phenomena known as chemtrails, lingering cloudy streaks left in the wake of some aircraft that are replete with heavy metal toxins like aluminum, barium and strontium.

Others have dismissed this as absurd, despite some regional testing by independent labs – and other government-sponsored initiatives such as the Air Force's 1990's initiative to control the weather via modification by 2025, which could be accomplished by "cloud seeding," which is already a commercial venture.

Well, whatever you believe, a new report reveals that the U.S. government actually has conducted biological and chemical experimentation on some of its citizens.

No accountability

As reported by Sputnik News, the experimentation was led by the U.S. military, shortly after World War II:

Just a few short years after America signed the Nuremberg Code, the US military conducted a secret bioweapons experiment on the city of San Francisco, without the knowledge of the people. The entire city was infected and one person died. But this wasn't the only instance. There were at least 239 documented cases.

The report noted that in San Francisco, circa 1950, the U.S. Army released a type of bioweapon fog that rolled in from San Francisco Bay. As reported by the San Francisco Chronicle in October 2004, the Army conducted a secret test involving serratia, a bacterium that was not, at the time, believed to cause disease. The science of the day was wrong.

As the paper reported further:

The Army used serratia to test whether enemy agents could launch a biological warfare attack on a port city such as San Francisco from a location miles offshore.

For six days in late September 1950, a small military vessel near San Francisco sprayed a huge cloud of serratia particles into the air while the weather favored dispersal.

Then the Army went looking to find out where it landed. Serratia is known for forming bright red colonies when a soil or water sample is streaked on a culture medium -- a property that made it ideal for the bio-warfare experiment.

Follow-up testing by Army researchers showed that the bacterium cloud exposed hundreds of thousands of people along a broad swath of Bay Area communities like Albany, Sausalito, Berkeley, Oakland and of course, San Francisco, according to documents that were eventually declassified.

History of death, disease

In the days and weeks after the spraying, 11 people came down with infections that were exceedingly difficult to treat at the old Stanford University Hospital in San Fran. By November, one of those patients had died; recovering from a prostate operation, Edward Nevin, 75, a retired Pacific Gas and Electric Co. worker, succumbed to serratia marcescens that attacked his heart valves.

Not knowing what was going on, the outbreak was so unusual that some Stanford doctors wrote it up for publication in medical journals.

In 1976, a reporter for the San Francisco Chronicle who was investigating the outbreak found no evidence that the Army had notified public health authorities. Dr. Lee Riley, a professor of infectious disease at UC Berkeley, told the paper in 2004 that the test, which seeded the Bay Area with serratia, may have been responsible for heart valve infections, which became more common following the test, as well as serious infections seen among intravenous drug users in the '60s and '70s.

Then, in 2001, serratia was also behind a number of instances of patients developing a painful, hard-to-treat form of meningitis. In that outbreak one person, 47-year-old George Stahl, died a day after receiving an injection of serratia-tainted cortisone, for his back pain.

No one was ever held accountable, to the public's knowledge, for the experiment gone awry.
