US experimented on humans with radioactive oatmeal, mystery fog | Elizabeth Vargas Reports
Yes — that NewsNation investigation by Natasha Zouves dives into what a lot of St. Louis residents have been asking for decades: was there more in that spray than the Army admitted?
Here’s the context behind the report:
🧪 The St. Louis Army “Mysterious Fog” Experiment
- In the 1950s–1960s, the U.S. Army’s Chemical Corps released zinc cadmium sulfide (ZnCdS) into the air over St. Louis, especially in North St. Louis neighborhoods where more than 10,000 people lived.
- The fog-like mist came from planes, blowers on rooftops, and vehicles.
- The official explanation: it was to study how particles would spread in a potential Soviet

Yes — this refers to two very real, but often little-known, episodes in U.S. history where humans were used in unethical experiments involving radiation exposure. Elizabeth Vargas’s Reports likely connects these historical events. Here’s the breakdown:
☢️ 1. Radioactive Oatmeal Experiments
- Where: Fernald State School (Massachusetts) in the 1940s–1950s.
- Who: Boys with developmental disabilities.
- What Happened: Scientists from MIT and Harvard, funded partly by the U.S. Atomic Energy Commission and Quaker Oats, fed children oatmeal laced with radioactive isotopes (iron and calcium tracers).
- Purpose: To study how nutrients were absorbed in the body.
- Consent: Families and children were not properly informed — they were told it was a “science club.”
- Exposure: Doses were small, but the ethical violation was enormous.
- Aftermath: In the 1990s, victims filed lawsuits. Quaker and MIT eventually settled for around $1.85 million.
🌫️ 2. The “Mysterious Fog” Experiments
- Where: San Francisco, 1950s.
- Who: Residents of San Francisco (unknowingly).
- What Happened: The U.S. Navy conducted a biological warfare test called “Operation Sea-Spray.” They sprayed bacteria (Serratia marcescens) into the air over the city to study dispersion in a coastal fog environment.
- Result: Many residents inhaled it unknowingly. At least one man died from a Serratia infection, though the government denied direct causation.
- Revealed: In the 1970s, documents surfaced showing the military had performed open-air biological and chemical tests in U.S. cities without consent.
⚖️ Why This Matters
- These experiments show how Cold War secrecy often overrode ethical standards.
- Today, they’re cited as key examples of why informed consent laws and bioethics regulations (like the Belmont Report) are necessary.
Would you like me to also list other similar U.S. human radiation/biological experiments (like Project 4.1 in the Marshall Islands or the Cincinnati radiation studies), so you can see the bigger picture?
