Mysterious Fog in the US , Canada and UK: A dense, eerie fog with a "burning chemical-like smell" has spooked a good part of North America and parts of the United Kingdom and Canada. With social media amplifying all concerns, this phenomenon has sparked attention across all social media platforms. However, at the heart of this mysterious fog are a conjunction of natural events, social psychology, and environmental conditions that culminated in all the conspiracy theories and public health fears. Here's a closer look at the mysterious fog, its potential causes, and the societal response it has triggered.

Fog that Feeds Fear

The first reports of this "mysterious fog" came in from Florida where a resident said that they experienced respiratory symptoms, feverish warmth, and stomach cramps after contact with the fog. Similar stories started flooding social media, and within a day or two, a sinister force seemed to sweep across the United States, Canada, and parts of the UK. From Texas to Minnesota, people reported weird odors and health issues that they thought were linked to this bizarre atmospheric event.

Some witnesses were said to see "white particles" swirling through the air; theories ranged from a chemical attack or experimental weapon to drone-related chemical dispersals and references to historical military experiments, such as the infamous 1950s "Operation Sea-Spray."

Fuel to the fire were added when videos and posts, hundreds of thousands in number, began circulating on social media sites like TikTok and X (formerly Twitter) speculating on the origin of the fog. Hashtags like #ToxicFog went trending for days. Hysteria created a self-reinforcing loop in which every post spurred further scrutiny and fear.

Scientific Explanation of the Dense Mysterious Fog

1. What is Fog?

Fog is essentially a low-lying cloud formed when the air temperature cools to its dew point, causing water vapor to condense into tiny droplets or ice crystals. Several types of fog—advection fog, radiation fog, and valley fog—can form depending on conditions such as warm, moist air moving over cooler land or when temperatures plummet rapidly under clear skies.

2. Why the Chemical Smell?

Such chemical-like smell as reported during the occurrence of fog events is sometimes attributed to air pollution. It acts like a sponge, where it absorbs these pollutants, which include sulfur dioxide and nitrogen oxides, among others, that emit from industries. This mixture, therefore, leads to a stench that could be mistaken as unnatural or even toxic.

3. What are the Health Concerns?

High moisture levels from fog can significantly exacerbate symptoms related to respiration, but especially in already predisposed asthmatics and allergy patients. The connection of these symptoms with actual fever, stomach cramps, and puffy eyes is too remote. Experts assume that the irritating effects of entrapped pollutants trapped in fog tend to affect more the eyes and throat rather than the rest of the body affected by some report.

Psychological Effects of Mass Panic Caused by Social Media

Social media amplified a natural weather event into a health epidemic. It made the personal experience of individuals become a cause for fear and speculation, a domino effect.

According to psychologists, this is a concept of selective perception, wherein once people's attention is drawn to environmental anomalies, they begin to notice them. This mirrors earlier panics, such as the Seattle windshield pitting panic of 1954. Then, atomic bomb testing caused fear in many and started to have people looking at their windshields for small marks that they had not seen before. Likewise, postings on the strangeness of the fog probably increased public awareness and suspicion, with people looking to attach unrelated symptoms to the phenomenon.

The fog hysteria shares a commonality with other instances of mass panic, such as the "drone sightings" of recent years or the Cold War-era fears of biological warfare.

These events underscore how fear can cloud judgment, especially when amplified by social media and sensationalist headlines. While historical cases, such as "Operation Sea-Spray," offer concrete evidence of the existence of unethical experiments, the jump from a natural weather condition to theories of chemical attacks exemplifies a more modern trend of connecting unrelated dots, all wonderfully seeded in distrust and anxiety.

Despite the swirling rumors, meteorologists and scientists are in agreement that the mysterious fog is not as alarming as it seems. It is well known that fog traps and amplifies pollutants, especially in urban and industrial regions. Moreover, winter months are the most conducive for fog formation, so its recent prevalence is unsurprising.

On the other hand, environmentalists advise that the fog should wake everyone up to increased levels of pollution. The reported odors and health irritations could be just symptoms of far deeper systemic issues like industrial emissions and lack of control over air quality.

The authorities must be transparent in their communication to combat misinformation and allay public fears. Governments and environmental agencies must provide timely updates on weather phenomena, air quality, and health risks. Initiatives like real-time pollutant tracking and public education campaigns can help demystify natural occurrences while addressing valid environmental concerns.

The mysterious Canada fog is a compelling case study in how environmental events intersect with psychology and societal dynamics. While rooted in natural phenomena, the fog became a vessel for collective fears, amplified by modern technology and historical anxieties.

In this information era where communication occurs at an almost lightning pace, the fog becomes a metaphor that reminds everyone about scientific literacy, environmental responsibility, and an effective balance when considering public concern. Whether perceived as a marvel of nature or as a tale that serves to teach, it left a very powerful mark in people's minds.

The FSSAI recently issued notices to three food business operators over what it described as misleading claims and labelling violations. The companies that have received notices are Heritage Foods Ltd for its paneer, Dia Foods for La Casa Vegan Hazelnut Chocolate Spread, and Cipzer Nutraceuticals for its juice capsules.

FSSAI Flags Down 3 Brands Over Misleading Claims

The food regulatory body directed the companies to provide explanations within seven days why action should not be initiated under the Food Safety and Standards Act, 2006.

The move is part of the regulator's broader ongoing crackdown on deceptive food packaging and marketing claims aimed at protecting consumers.

Heritage Foods' Fresh Paneer Under FSSAI Scrutiny

FSSAI issued a notice to Heritage Foods, objecting to the use of the term “Fresh Paneer” on the packaging. It stated that the claim term does not meet the conditions laid down under Schedule V governing the use of the word “fresh”.

According to the regulator, the label “Fresh Paneer” is liable to mislead consumers because it does not satisfy the prescribed criteria for using the term.

La Casa Vegan Chocolate Spread Accused Of Misleading Claims

FSSAI also issued a notice to Dia Foods over its La Casa Vegan Hazelnut Chocolate Spread, alleging that several claims displayed on the packaging could mislead consumers. Among the claims questioned are:

• "All Natural"

• "100% Organic"

• "Vegan"

The regulator further pointed out that the product uses the phrase "100% Organic & Vegan”, which could be misleading as it has not obtained approvals like organic and vegan food.

Further, according to FSSAI, the packaging does not display the mandatory organic certification marks, including the Jaivik Bharat logo required under Indian regulations.

It also objected to its use of “100%” as the food regulatory body has stated that it cannot be defined under FSS Act, 2006.

Cipzer Nutraceutical Also Got Served

A third notice was issued to Cipzer Nutraceuticals over its juice capsules. FSSAI said the product carries claims that violate food labelling and advertising regulations.

In its notice, it said that the product carried the claim “FSSAI-approved” which could imply that FSSAI specifically endorsed it.

Other reasons listed in the complaint stated that the product boasted of claims like “Boost your immune system” and “remove toxins from your body”, which had no scientific backing. It also said the product’s packaging depicted pictures of various vegetables that were listed in the ingredient list.

The regulatory body added that the product also claimed the presence of Vitamin C and Vitamin E but failed to substantiate it scientifically.

The makers also claimed that the capsules are “made from organic vegetables”. FSSAI said that it could mislead the consumers as it does not carry the prescribed organic certification, including Jaivik Bharat Logo.

FSSAI’s Recent Crackdowns

The latest notices are part of FSSAI's ongoing crackdowns against misleading food claims. In recent weeks, the regulator has issued notices to several food companies over the use of terms like “100%,” “healthy,” “organic,” “natural,” and “fresh” as they do not comply with food labelling and advertising regulations.

The regulator has maintained that such claims can influence consumer purchasing decisions and must be scientifically substantiated and legally compliant.

Prominent brands that faced FSSAI scrutiny includes Red Bull Energy Drink, PepsiCo – Adrenaline Rush Energy Drink, Reliance Consumer Products – Campa Energy Gold Boost, Sting Energy Drink, Hell Energy, Coca-Cola-backed Monster, Eat Fit Digestive Biscuits, Emami (Healthy & Tasty), Health Aid, Troovy, The Healthy Factory, Healthy Master, Healthy Choice, Plan B Foods, and Neuherbs.

HealthandMe had reported food contamination from Indore's Bhagirathpura, the same place that was the epicenter of water contamination that claimed many lives. HealthandMe also reported the news of Horlicks adulteration in Odisha.

In another news, bacteria were found in Amul milk packages, along with Mother Dairy and Country Delight. Eggoz, too, landed in a controversy, when a YouTube video went viral claiming that the sample tested positive for Nitrofuran.

MicrobioTx, a Bengaluru-based gut health startup, tested samples from urban populations across 9 Indian states and 14 cities and found that people are significantly exposed to pesticides, insecticides, antibiotics, steroidal growth regulators, and forever chemicals.

The independent study reported the following findings:

• 78% were exposed to pesticide residues, with 36% exposed to three or more pesticides, indicating cumulative exposure that may pose serious health risks.

• 54% showed presence of antibiotics, linked to antimicrobial resistance, harder-to-treat infections, and disruption of the gut microbiome that may contribute to metabolic disorders.

• 39% were exposed to steroids, compounds that may cause endocrine disruption, and increased carcinogenic risk.

• 38% tested positive for forever chemicals, persistent toxins that may cause cancer risk, reduced fertility, thyroid disease, hormone suppression, high cholesterol, liver damage, and ulcerative colitis.

• 17% of the samples had 10 or more toxins in their blood across 3 categories, indicating hidden chronic exposure.

The cyclospora parasite outbreak in the US is continuing to grow, with cases nearing 900, according to local health officials.

While infections have been reported in about 18 states, Michigan and Ohio continue to see the highest number of cases of the intestinal infection.

As of July 6, 678 cases of cyclosporiasis had been confirmed, an official from the Michigan Department of Health and Human Services (MDHHS) told ABC News. This is an increase from roughly 300 cases reported last week. The state annually records up to 50 cases, but the current outbreak is about 13.5 times higher than average.

According to Dr. Natasha Bagdasarian, an infectious disease physician, epidemiologist, and the chief medical executive for the state of Michigan, the figure is a "moving target," meaning cases are likely to continue rising.

"There is a significant lag time between exposure to contaminated produce or contaminated materials and development of symptoms," she told ABC News. "So it can take a week, sometimes even two weeks between exposure and development of symptoms."

In Ohio, there were 177 cases of cyclosporiasis as of July 2, Ken Gordon, press secretary for the Ohio Department of Health's communications office, was quoted as saying.

Cases have been confirmed across 43 counties in Ohio so far this year, according to Gordon. Nearly 171 cases have been reported since June 20.

Meanwhile, the Centers for Disease Control and Prevention (CDC) reported that 145 cases had been detected in 17 states since May 1, excluding Michigan, as of June 16, with at least 20 people hospitalized. No deaths have been reported.

The CDC said cases ranged in age from 5 to 86 years, with a median age of 42. About 61 per cent of patients were female.

So far, no cases have been linked between states, and health officials are still investigating whether there is a common source of the outbreak in Michigan.

How to Prevent Cyclospora Infection

The CDC recommends following safe food handling practices to reduce the risk of infection:

• Wash your hands with soap and water before and after handling fresh fruits and vegetables.
• Wash all fruits and vegetables thoroughly under running water before eating, cutting, or cooking.
• Produce labeled "prewashed" does not need to be washed again.
• Scrub firm produce, such as melons and cucumbers, with a clean produce brush.
• Cut away any bruised or damaged areas before eating.
• Refrigerate cut, peeled, or cooked fruits and vegetables within two hours.

The parasite spreads through food or water contaminated with human feces and is not spread directly from person to person.

According to Dr. Darien Sutton, an emergency medicine physician, proper handwashing is very important.

"This type of parasite doesn't easily go away with alcohol-based hand sanitizer. So, good old handwashing is really key here," said the ABC News medical correspondent.

Cyclospora cayetanensis is a parasite that causes cyclosporiasis, a form of food poisoning.

People can become infected through contaminated food or water. The infection causes watery diarrhea and other intestinal symptoms.

A Cyclospora infection can be mild or severe and may last for weeks or even months. It is typically treated with antibiotics.

People with weakened immune systems, such as those with HIV/AIDS or cancer, are at greater risk of severe disease.

Symptoms of Cyclospora Infection

Symptoms of cyclosporiasis usually begin within a week of exposure to contaminated food or water and include:

• Watery or explosive diarrhea
• Loss of appetite
• Bloating and gas
• Fatigue (extreme tiredness)
• Low-grade fever
• Nausea
• Stomach cramps
• Vomiting.

The launch of the weight-loss drug Wegovy has sparked fresh concerns among pharmacists in the UK, who warn that the new tablet format could make it easier for manufacturers to produce and sell counterfeit medicines.

Wegovy Demand Sparks Counterfeit Concern

The once-daily semaglutide pill, developed by Novo Nordisk, recently became available through private high street and online pharmacies after receiving approval from the UK's Medicines and Healthcare products Regulatory Agency (MHRA).

While the pill is expected to help patients who are reluctant to use injections, experts fear it may also increase the risk of a growing black market for fake weight-loss drugs.

According to a survey conducted by the National Pharmacy Association (NPA) with 310 pharmacies, 97% believe that the weight loss tablet could lead to an increase in counterfeit products being sold unlawfully.

Olivier Picard, chairman of the National Pharmacy Association said, “As this survey shows, pharmacies are concerned about a dangerous and growing black market for weight loss medicines, with tablet form of medication likely to be easier for criminals to counterfeit.”

He said that all patients must visit an authorised pharmacy for Wegovy pills.

He added: “Patients should only ever obtain weight loss medication from a regulated pharmacy after an appropriate consultation with a healthcare professional. Fake medicines pose a serious risk to health because they may contain harmful ingredients or incorrect doses.”

Global Concern

Unlike injectable medications of GLP-1, tablets often require less sophisticated manufacturing equipment, which makes it easier to make counterfeits.

As the medicated weight loss market is rising after the popularity of GLP-1 medications increased, criminals can produce fake pills on a large scale, using simple equipment.

Counterfeit GLP-1 medicines have already become a growing global concern. In September 2025, the European Medicines Agency (EMA) said that there had been a sharp rise in illegal forms of semaglutide and other GLP-1 medicines online.

The agency also warned that these fake medicines may contain no active ingredient, improper doses, or harmful substances that can lead to failure of treatment or serious health complications.

Demand for GLP-1 medicines such as Wegovy and Mounjaro has soared worldwide as studies continue to demonstrate significant weight loss benefits.

Clinical trials of the oral Wegovy tablet have shown participants taking the highest dose lost approximately 14% to 17% of their body weight over 64 weeks when combined with diet and exercise. However, pharmacists say the popularity of these treatments has also created opportunities for fraudsters.

Experts urge consumers to avoid purchasing weight-loss medicines from unofficial online sellers or social media advertisements, regardless of how attractive the prices appear.

Genuine GLP-1 medicines require a medical consultation and prescription, and authorised pharmacies carry out necessary clinical checks before selling them.

About Wegovy

The semaglutide (Wegovy) tablet is the first oral glucagon-like peptide-1 (GLP-1) medicine approved in the UK for weight loss.

It can be prescribed alongside a reduced-calorie diet and increased physical activity for adults who have obesity (BMI of 30 or above), or are overweight (BMI between 27 and 30), and have at least one weight-related comorbidity
