Often first noticed as a fuzzy patch on stale bread, mold represents a more extensive issue than many realize. It’s a common fungus in our environment, subtly present in many foods, from morning coffee to the nuts in our snack drawer. While mold plays a crucial role in nature by decomposing organic matter, its unseen presence in our food can pose health risks.
Health Consequences of Mold Exposure
Often underestimated, mold exposure can have far-reaching consequences. Molds produce mycotoxins, especially in warm, humid conditions. These can cause reactions varying from mild allergies to severe health conditions.“I think most people, including physicians in the United States, are unaware of all the ways mold in foods can cause disease,” Dr. David Corry, a professor at Baylor College of Medicine in Houston, told The Epoch Times.
The challenge in diagnosing mold-related health issues, often presenting symptoms such as chronic fatigue and brain fog, lies in their similarity to other medical conditions. Dr. Corry emphasized this complexity, noting, “Food mold-related diseases also mimic many other conditions, hindering accurate diagnoses and delaying appropriate care.”
That misdiagnosis is frequently because of a lack of awareness within the medical community about the health effects of common fungi and their toxins, coupled with the diverse symptoms of mycotoxin poisoning that can resemble various unrelated conditions, he said.
Heavy mold contamination in foods poses several other health risks, particularly when mold spores become airborne, Dr. Corry said.
“The spores can cause severe respiratory allergic reactions if people have been pre-sensitized to that mold,” he said.
These reactions range from mild symptoms such as coughing and sneezing to severe conditions such as asthma exacerbations and potentially life-threatening respiratory infections.
Mold’s Path From Farm to Kitchen
Mold’s infiltration into our food is a complicated and frequently obscured process. The U.S. Department of Agriculture (USDA) recognizes aflatoxins as an “unavoidable risk” in food production. About 25 percent of global food crops are impacted by mycotoxins, particularly aflatoxins, according to the agency.5 Culprits in the Kitchen
Kitchens can become breeding grounds for mold and its byproducts, Dr. Corry warned.“Molds can grow in and on virtually any food, so everyone needs to become an expert at inspecting all foods to identify mold contamination and act accordingly,” he said.
For many items such as jellies, yogurt, fresh produce, and meats, visible mold suggests contamination, warranting trimming or disposal of the affected parts. Conversely, some foods, such as certain cheeses and a few processed meats, are meant to have mold and are safe to consume.
1. Coffee
Your morning coffee might hold a hidden surprise: mold. From the tropical farm to your cup, coffee beans face mold risks at every stage. The damp processing, lengthy humid transport in burlap sacks, and even the roasting process all threaten the beans.

2. Nuts and Peanuts
While nuts and peanuts are celebrated for their nutritional value, they also carry a hidden risk: aflatoxins. A 2023 study examining nuts and nut products discovered a significant presence of aflatoxins. This analysis, involving more than 5,400 samples from 57 countries, identified high aflatoxin levels in pistachios, peanuts, and mixed nuts—often exceeding safety standards.3. Corn
Corn, integral to human and animal diets, is also susceptible to mold contamination. When corn is affected by mycotoxins, such as aflatoxins, it poses notable health risks throughout the food chain. Resistant to cooking and processing, these mycotoxins can accumulate in the tissues of animals consuming mold-tainted corn.4. Dry-Cured Meats
Dry-cured meats, such as prosciutto, salami, and chorizo, are renowned for their rich flavors and artisanal methods. Yet these very processes that contribute to their distinctiveness also pose potential risks for mold contamination.In traditional dry-curing, meats are aged under conditions perfect for flavor development but also favorable for mold growth. While some molds are harmless or even enhance flavor and texture, others can be harmful.

5. Dried Fruit
Dried fruits, popular for their sweet taste and nutritional benefits, face the risk of mycotoxin contamination. The process of drying these fruits not only concentrates their natural sugars but also has the potential to amplify mycotoxins, particularly if the original produce was already contaminated.Safeguarding Your Plate
While occasional exposure to mycotoxins may not significantly impact a healthy individual, it’s important to consider the cumulative effect of toxins, from environmental pollution to household chemicals, on our “toxic load.” A higher toxic load can increase susceptibility to mold-related health issues. Therefore, understanding and reducing our overall exposure to these toxins, including those from mold in food, is essential.Implementing practical measures such as appropriate food storage, vigilant inspection for mold, and safe consumption practices are key to minimizing mold risk in our diets. Critical actions include storing food in cool, dry conditions and conducting thorough inspections for any signs of mold.
Despite best efforts in food handling, such as maintaining proper refrigerator temperatures and discarding items left out for extended periods, it’s crucial to recognize that refrigeration alone isn’t a foolproof solution.
“Molds will eventually grow on continuously refrigerated foods if left in the refrigerator long enough. Refrigeration is not a guarantee against mold contamination,” Dr. Corry cautioned.
He also emphasized proactive health management in relation to food mold. “Individuals suspecting health issues related to food molds must take control of their food supply and adopt the food safety practices discussed above,” Dr. Corry said.
He advised that those seeking medical attention for mold-related illnesses find a physician with specialized expertise, acknowledging the general lack of awareness in the medical community.
