Mysterious ‘chemical fog’ sweeps across U.S., sparking bioweapon fears and health concerns

• A mysterious fog with a chemical-like smell has spread across multiple U.S. states, causing flu-like symptoms and sparking fears of a potential bioweapon experiment.
• Residents report symptoms like sneezing, fever, and respiratory distress after brief exposure, with some comparing the fog to the 1950s “Operation Sea Spray.”
• Social media is flooded with claims of unnatural fog and chemtrails, fueling conspiracy theories about government experiments or pathogen dispersal.
• Public distrust persists due to the U.S. government’s history of secret experiments and lack of transparency, despite experts stating the fog is likely a natural phenomenon.

A thick, mysterious fog has descended upon multiple states across the U.S., leaving residents baffled and concerned. Reports of a “chemical-like smell” and flu-like symptoms following exposure have sparked fears of a potential bioweapon experiment, reminiscent of the infamous 1950s “Operation Sea Spray.” From Florida to Kansas, residents are questioning whether this fog is a natural weather phenomenon or something far more sinister.

The fog, which has been reported in states including Texas, Wisconsin, Iowa, Maryland, Virginia, and Florida, has been described as having an unnatural appearance and odor.

“It smells like the aftermath of a fireworks show, and it tastes toxic,” said David Bamber, a resident of St. Petersburg, Florida, in a TikTok video. Others have reported symptoms such as sneezing, fever, stomach cramps, and respiratory distress after brief exposure.

The eerie parallels to “Operation Sea Spray” have only fueled public anxiety. In 1950, the U.S. Navy conducted a secret biological warfare experiment off the coast of San Francisco, spraying Serratia marcescens and Bacillus atrophaeus into the air. The bacteria, believed to be harmless at the time, caused severe illnesses in 11 people, one of whom died. Now, 75 years later, some fear history may be repeating itself.

Social media has been flooded with videos and posts describing the fog as “unnatural” and “chemical-like.” A Florida resident told the Daily Mail that after stopping at a gas station for just 10 minutes, she experienced a coughing fit, fever, and stomach cramps. “Within about an hour, I kept sneezing over and over for about three hours, and my eyes were really puffy,” she said.

In Kansas, a woman reported seeing “massive amounts of chemtrails” followed by dense fog, while a California resident posted on X: “Here in SoCal, unusual fog the last few days. Strange smells, but I’ve been noticing the smell for months now, burns my nose. Seems like an all-out assault from the skies the last few days.”

Conspiracy theories have run rampant, with some suggesting the fog is linked to the mysterious drone sightings that plagued parts of the U.S. in December. “Guys, they dumped a bunch of microbes on the country this week, in the form of fog,” one X user posted. “I know it sounds tin-foil, but my Spidey senses are telling me they are seeding the skies with pathogens that make us sick.”

Scientific explanations and skepticism

While the National Weather Service (NWS) has issued dense fog advisories for multiple states, attributing the phenomenon to natural weather patterns, skepticism remains. Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air. When light shines through it, the droplets scatter, creating the appearance of particles.

The “chemical” smell reported by residents may be due to fog’s ability to absorb and trap pollutants near the Earth’s surface. “When fog forms, sulfur oxides, nitrogen oxides, and other polluting gases are taken up or ‘scavenged’ by fog water droplets,” explained Rudolf Husar, an atmospheric scientist at Washington University. Additionally, humid air can intensify odors, making them more noticeable.

Respiratory symptoms reported by residents are also consistent with natural fog. Studies have shown that inhaling moisture-laden air can irritate the respiratory system, particularly in individuals with asthma or other pre-existing conditions.

A history of experimentation

The public’s fears are not entirely unfounded, however. The U.S. government has a history of conducting secret experiments on its citizens. In addition to “Operation Sea Spray,” the 1950s saw the release of zinc cadmium sulfide over St. Louis to simulate a bioweapon attack. While officials claimed the chemical was harmless, later investigations revealed potential health risks.

The lack of transparency from the Biden administration regarding the fog and previous incidents, such as the drone sightings, has only deepened public distrust. “Did we just suffer another Operation Sea Spray event—The Fog?” one X user asked.

While the fog currently blanketing parts of the U.S. is likely a natural weather event, the public’s concerns are understandable given the government’s history of secret experiments and the lack of clear communication. For now, experts urge caution but stress that there is no evidence to suggest the fog is anything other than a winter weather phenomenon. However, as long as questions remain unanswered, the mystery—and the fear—will persist.
