Why is it that mold affects each person differently? How come some people present no symptoms at all or they tend to recover from symptoms as soon as the source of the mold is eradicated, while others develop chronic health problems from a single encounter with mold? The answer lies in a person’s genetic predisposition toward mold illness, which stems from the HLA-DR gene.

Note to readers: The particulars behind HLA-DR’s problematic effect on the immune system require delving into expansive details of the Major Histocompatibility Complex (MHC) in humans, as well as the definition and functions of various molecules and proteins—such as antigens, peptides, and T-cell receptors, to name a few—in relation to the pituitary and hypothalamic axis, and the immune system as a whole. For those of you who are biology buffs, I apologize for oversimplifying things. And, for those of you who dreaded every day of high school biology, well, you’re welcome.

Without further ado, let’s jump right in and butcher a very complex problem with a very modest explanation.

What is the HLA-DR Gene?

The Human Leukocyte Antigen is a protein—or marker—that is found on most cells in your body. Your immune system uses these markers to recognize which cells belong in your body and which cells do not. When an antigen is presented correctly to a T-cell receptor, for example, the appropriate immune response is given and foreign threats can be destroyed or removed from the body. This is an imperative function in the defense against biotoxins—toxic substances that have an organic origin, such as mycotoxins (fungi—yeast and mold), zootoxins (animals), and phytotoxins (plants).

When a person carries the HLA-DR gene, however, they are genetically susceptible to biotoxic illnesses because the HLA-DR causes a misprocessing of antigens, which inhibits the immune system from reacting correctly to infection and toxins.

HLA-DR and Mold Illness

Fungal triggers of the HLA-DR are often the most devastating to health. Over 36 different diseases can result from an HLA-DR carrier’s exposure to mold. This is because HLA-DR(BQ) inhibits the immune system from recognizing mycotoxins as a threat, thus impeding it from producing antibodies that are needed for deactivating and removing mold toxins. Because of this, mycotoxins and aflatoxins are stored throughout the body (namely in the “fatty” regions, such as the brain) while their negative effects go undiagnosed or incorrectly treated by the immune system for weeks, months, years, or even a lifetime.

Because the mycotoxins are misprocessed and stored, the immune system will overreact to toxic and non-toxic materials. It can lose its ability to correctly differentiate between “self” and “foreigner,” often misfiring and wreaking more havoc on the body than the mycotoxins would have done on their own. In short, HLA-DR and mold illness are synonymous with autoimmune disease and disorder.

When a group is exposed to mold, the HLA-DR carriers will be the first to experience an immune response and the last to recover—if they recover at all. Rarely does the HLA-DR victim suffer only the first line of defense markers for mold sickness, such as:

  • watering, irritated eyes
  • red eyes
  • hives
  • sneezing
  • runny nose
  • nausea
  • vomiting
  • burning sensations in airways
  • a tightening in the chest
  • cough
  • nuances of asthma
  • nosebleed
  • fever
  • numbness/tingling
  • a long, painful headache

Instead, they’re more likely to experience many of those symptoms long term and more intensely than non-carriers who were exposed to the same mold for the same duration of time. In addition, they’re now more susceptible to other chronic and seemingly-unrelated illnesses, disorders, and diseases (because HLA-DR permits the storing of mold toxins that eventually destroy neurons in the brain and disrupt hormone production):

Acne (cystic, as well)



Autoimmune diseases

Balkan nephropathy (a type of kidney disease)

Brain disorders

Bronchitis (repeat occurrences)

Celiac disease (severe gluten intolerance that puts the small intestine at risk)

Chronic sinus congestion

Colitis (inflammation of the colon lining)

Dry skin (dull, ashy-looking skin, cracked heels, chapped lips)

Epstein-Barr Virus (“Mono”)

Gastrointestinal issues

Graves Disease (i.e. hyperthyroidism)

Gum disease

Hashimoto’s Disease (autoimmune disease that damages the thyroid gland)

Heart Disease

Hepatocellular carcinoma (primary type of liver cancer)

Histamine intolerance

Insulin resistance

Irritable Bowel Syndrome (IBS)

Joint-connective tissue disorders

Kashin-Beck disease (death of bone and joint cartilage growth plates, resulting in disruption of normal growth in children and adolescents)

Lupus (inflammatory autoimmune disease that attacks the body’s healthy tissues and organs)

Lyme’s disease

Memory problems (short term)

Multiple Sclerosis

Parkinson’s Disease


Respiratory infections

Reye’s syndrome (swelling in the liver and brain—mostly occurs in children and teenagers)

Rheumatological disorders (r. arthritis)

Scalp issues (lesions, rashes, acne, abscesses, cysts)


Sjogren’s Syndrome

“Static shock” occurrences more frequent (caused by higher salt content due to dehydration)

Thirst (unquenchable)

Thyroid dysfunction

Weight gain (sudden)

Worsening vision

And so much more…

What Are the Chances That You Are a Carrier of the HLA-DR Gene?

So far, it’s been established that roughly 25% of the population is a carrier (and sufferer) of the HLA-DR gene. That’s over 80 million people in the United States alone! New research, however, is emerging that indicates that the initial assessment could be drastically inaccurate. Genetic studies on certain populations now suggest that the true number could be anywhere between 40% and 60% worldwide!

In one study conducted on four different populations, including an isolated Hutterite population, it was determined that, while those working regularly in agriculture showed mildly increased cases of mold sensitivity and asthmatic symptoms, the predisposition toward mold sensitivity and related allergens/illnesses, certainly appears to be genetic and estimated to affect around 60% of the population. It was originally assumed that isolated “inbred” groups (closely and distantly related) were more likely to pass on these susceptibility genes, but after expanding their research to include several “outbred” groups from large, multi-racial cities, they discovered that cases of genetic mold sensitivity only dropped by 10 to 20% (due to gene variance). In other words, this alarmingly high percentage of genetic mold sensitivities is not dependent on tight-knit communities of distant cousins, nor is it dependent on whether or not the lifestyle centers on agriculture. Even the most genetically-diverse populations teeter between 40% and 60% (as mentioned before).

Is There Anything Good About Having the HLA-DR Gene?

Several health professionals and genetics experts would argue that carriers of the HLA-DR mold-sensitivity gene act as canaries for the health and safety of the population at large.

Mold affects everyone, even those who aren’t genetically vulnerable to it. Some mold victims seem to be asymptomatic, but given enough exposure time to a toxic mold, they’ll eventually succumb to a mold-related illness or disorder. Mold is not always growing where it is visible to the naked eye, especially in older buildings. Centuries-old homes, apartments, and municipal buildings, for instance, often have deep rot and mold infestation within the inner structures. This is why, in a sense, it is good to have HLA-DR carriers because their immediate immune response to mold could act as a warning sign to others in a home or workspace that mold is present. (Of course, this is assuming the carrier and others are able to diagnose the symptoms correctly.)

What Can Be Done if You are a Carrier of HLA-DR?

While it does leave the immune system vulnerable to biotoxins, it doesn’t have to be a death sentence. The most important point to take home, regarding HLA-DR, is that it is genetic, which means that, if you are a carrier, the effects of the HLA-DR gene will permanently govern the way you live your life. While your spouse, friends, or coworkers may experience a restoration of full health once mold exposure is diminished, you will have to actively encourage your body to heal from mold illness with lifestyle choices, such as an anti-fungal diet or an anti-fungal supplement routine, in addition to detoxing exercise and adequate sleep.

In other words, HLA-DR carriers, unlike non-carriers, will have to actively pursue a course of treatment and live a specific lifestyle that promotes biotoxin shedding.

Testing for the HLA-DR Gene

WARNING: If you believe you are a carrier of the HLA-DR gene, please do NOT pursue testing through commercial DNA testing agencies, such as 23andMe, AncestryDNA, National Geographic Geno 2.0, or any other like service. These agencies are not required by law to follow HIPAA guidelines, which means they have the right to sell your genetic panel to insurance companies. This could result in a denial of insurance coverage or a rise in the cost of insurance should you prove to have pre-existing conditions or medical predispositions.

For the most part, testing for the HLA-DR gene is not necessary when determining treatment options for the various illnesses and disorders encouraged by it. However, it might be helpful to a potential carrier if they obtain proof of their genetic susceptibility to mold sickness for the purpose of cautiously planning their lifestyle and living conditions, as well as establishing medical or legal recourse in the case of inept diagnoses and property negligence.

Unless you are able to convince your doctor to see the HLA-DR genetic panel as a necessity in their diagnosis and treatment, be aware that insurance will not cover the blood tests or the reading of the test results. In general, prices range between $300 and $400 if you must order the testing yourself.

Blood testing for HLA-DR is available through the LabCorp and Life Extension laboratories.

Important Note: Those familiar with the Quest Diagnostics laboratory should not confuse their HLA blood test for the HLA-DR mold illness susceptibility panel. A standard HLA blood test will only yield results in terms of tissue donor matching. Quest Diagnostics does offer the C3A and C4A tests that determine whether a person has been exposed to mold recently or long term, but those tests will not shed light on underlying genetic susceptibilities and are only useful in certain scenarios.


Unbeknownst to many, the HLA-DR gene affects between 40% and 60% of the world’s population. It accounts for a greater susceptibility to yeast and mold illnesses, as well as autoimmune diseases.

Carriers of the HLA-DR gene are prone to develop chronic health issues involving systemic inflammation, whether the cause is mold, Lyme’s, gluten, or countless other catalysts. Not only does HLA-DR make a carrier vulnerable to chronic biotoxin disease, it also makes detoxification and healing extremely difficult. Thankfully, there is hope with a strict adherence to preventative and detoxifying protocols.

Got Mold? 4 Ways to Assess Your Mold Risk Mon, 26 Aug 2019 17:38:55 +0000 It is when mold begins growing in places we do not want it (such as in our homes) that it becomes a serious issue that can negatively impact our health and the longevity and safety of our house. That is why is it important to regularly check and evaluate the mold risk of the place in which we inhabit.]]>


Can You See Mold?

They say a picture is worth a thousand words, and when it comes to mold, seeing it is a sure indicator that you have a problem. Visually spotting the mold is the most obvious way to determine if you have mold in your home. If mold is growing on walls, ceilings, in cabinets, etc, you most likely have something going on that is encouraging the mold growth, such as a leak, or a humidity issue. The item that is causing the mold is important to fix, even before you begin to think about how to get rid of the mold, because if you don’t fix the root cause, the mold will inevitably return.

If you have high humidity in your home, you may want to periodically move your furniture to make sure mold isn’t growing on the wall behind it. I have discovered this type of mold issue growing several times when I lived in a very humid and wet climate. Dehumidifiers can be excellent to add to your mold prevention protocol if the issue is high humidity and not a leak.

Can You Smell Mold?

Is there a constant musty smell in your home or in certain areas of your residence? Is there a wall that emanates a scent that just doesn’t seem normal? If so, you may want to test and/or do a little investigation to see if there is some mold hiding somewhere.

When I was pregnant with my third, we were renting an apartment and each day in the summer, when the sun hit our southern wall, which was the wall in the kitchen, a smell that made me feel sicker than my normal morning sickness with the pregnancy began to grow and get stronger as the suns rays heated up that side of our home. I told my husband that there must be mold in that wall (I have had previous experience with mold sickness and was having symptoms again). Finally, he did some investigating behind the dishwasher and found the mold, and a leak from a slice in the plumbing that was continuously pouring in the surrounding wall. Apparently, whomever had been hired to do the plumbing for the apartment had cut the pipe in the wrong spot and then cut in the right spot, but then installed the partially cut pipe that leaked from day one! Always double check your plumbing to make sure there are no leaks that will grow a garden of mold in your home.

Do You Feel Sicker at Home?

Are you constantly feeling sick, and is it worse when you are at home? Do you experience unexplained respiratory issues, headaches, etc? Sick building syndrome is a real issue that many occupants of homes and buildings suffer from. The NCBI characterizes the signs and symptoms of sick building symptoms as: “Headache, dizziness, nausea, eye, nose or throat irritation, dry cough, dry or itching skin, difficulty in concentration, fatigue, sensitivity to odors, hoarseness of voice, allergies, cold, flu-like symptoms, increased incidence of asthma attacks and personality changes.” There can be many factors related to sick building symptom other than mold, and the cause of it is unknown, however, if you constantly feel sicker at home and suspect a possible mold problem, you may want to test your home for that possibility. 

Test Your Home

If you an unsure whether or not your home is infested with mold, or if you are purchasing a home and want to make sure you are not buying a mold headache to deal with, it may be a great idea to test your home for mold. There are many different ways to test your home, whether by hiring a professional to inspect and test, or by performing your own mold test, such as an ERMI dust test. It is a good idea to research which option is the best and most thorough way to test for your budget and situation.

The Complete Guide to Black Mold Tue, 02 Jul 2019 17:00:23 +0000 What is Black Mold? Stachybotrys, otherwise known as “black mold,” has a rather notorious—and nefarious—reputation worldwide, but what makes black mold so dangerous and unique from other molds? And, why is it so important that you learn how to recognize the signs of black mold in your home or the black mold symptoms within your […]]]>

What is Black Mold?


Black Mold Facts

How Does Black Mold Grow?

Like any other mold, black mold growth is the result of a mold spore (or millions) landing and taking root in an accommodating environment—damp, dark, and full of decaying organic material (which it uses for nourishment).

While black mold is satisfied with the bare minimum requirements, it prefers spaces that are absolutely saturated with moisture. This is why black mold is more commonly found among soaked materials in humid climates and, though it can take root in almost any material, it favors those made of cellulose (i.e. cardboard, hay, paper, wicker, wood).

Mold spores somewhat mimic plant seeds in that, after they reach an environment conducive to growth, materials extend from the spore itself for both the gathering of sustenance and the establishment of supportive roots and a main body above the surface that makes further reproduction possible. (This is why mold was so often confused for a species of plant for many years.)

First, the threadlike structures of the hyphae (similar to plant roots) are spread out atop (and within) the surface where they can secrete enzymes for the purpose of breaking down the organic matter for nutrient-absorption. When nourishment is assured and obtained, the mold then has the energy needed to begin growth of the mycelium, which is the visible portion of the mold that can look moss-like or even hairy due to its fibrous networking of materials. After that, the mold develops reproductively, creating mold spores that can be released on the air current or through physical contact with an animal or person. And, with each spore, the cycle begins anew.

What Does Black Mold Look Like?

To start, what does black mold look like? What you might find interesting is the fact that, for a mold so infamously described as “black,” it’s actually a dark green color, but it’s a dark enough shade that it can resemble black to the distant and naked eye. Not to mention, there are already a vast array of green molds with varying levels of toxicity, so stachybotrys couldn’t rightly be referred to as the “green mold.” It needed a common, but unforgettable name in order to signify its distinction from the rest, as well as the implication that it is deadly and worthy of fear—not unlike the term “black death” or “black plague.”

What Makes the Color of Black Mold so Important?

Does the color of black mold matter? Well, actually, it does. Those who have had the misfortune of playing host to black mold and the severe black mold symptoms that inevitably follow, can attest to the difficulty of killing and removing it from their homes, as well as the long-term effects it has on their health.

This is because the more melanin a mold produces—which determines its hue—the stronger and more resilient it is. The stronger and more resilient a mold is, the more likely it is to become a long-lasting nuisance to your health and a permanent guest in your home. In other words, yes, the color is an indication that not much can interfere with black mold’s ability to mature quickly, spread rapidly, and release millions of mycotoxins into the air that have the potential to inflict deadly responses in the body.

Why is Black Mold So Dangerous?

While all molds have the potential to be dangerous—depending on the amount (and length) of exposure and the sensitivity of the person—black mold provides a threefold threat to human health that far exceeds what other molds are capable of.

There are three levels of harm that determine the potential threat of a mold:


Black mold can afflict all three levels of harm, which certainly makes it a mold worth discussing and watching out for.

Symptoms of Black Mold

Mental and Neurological Symptoms of Black Mold

What makes black mold so uniquely dangerous is that it produces trichothecene mycotoxins, which are amongst the most toxic substances on the planet. Trichothecene mycotoxins are neurotoxins. Neurotoxins negatively affect the brain and nervous system. They have the capacity to destroy neurons in the brain, impair mental ability, cause nervous disorders (such as tremors), and cause changes in personality.

Frightening Fact #1: Trichothecene mycotoxins are the only mycotoxins that have been used as biological weapons. This is because they are highly stable in the air, they don’t degrade under ultraviolet light, they’re able to withstand high heat, they reproduce rapidly, and they absorb through the skin and air passages quickly and efficiently.


  • Aggression
  • Anxiety
  • Brain fog
  • Changes in personality
  • Confusion
  • Depression
  • Difficulty concentrating
  • Disorientation
  • Dizziness
  • Hallucinations
  • Impaired learning ability
  • Memory loss
  • Mood swings
  • Numbness
  • Poor short-term memory
  • Seizure
  • Shaking
  • Shock
  • Shortened attention span
  • Shortened temper
  • Slowed reflexes
  • Tingling
  • Trembling

Respiratory (and Oral) Symptoms of Black Mold

Every mold affects the respiratory system. Black mold is certainly no exception. Not only are the lungs affected, but the air passages and mucous membranes of the nose and mouth fall victim, as well.


  • Bleeding gums
  • Burning sensation of the mouth
  • Coughing
  • Difficulty breathing (breathlessness or shortness of breath)
  • Itchy nose
  • Nose bleeds
  • Pulmonary edema (swelling of the lungs)
  • Pulmonary hemorrhage (bleeding in the lungs)
  • Sore throat
  • Stuffy nose
  • Wheezing

Circulatory Symptoms of Black Mold

Because the spores and mycotoxins of black mold can be breathed in, absorbed through the mucous membranes (eyes, nose, mouth), ingested, or even absorbed through the skin, the toxins have easy access to the blood. With enough exposure (or if a person is particularly sensitive), this can lead to heart damage, as well as problems with blood clotting and hemorrhaging (both internal and external).


  • Bleeding in the brain (and other organs)
  • Bleeding tendency
  • Bone marrow disruption
  • Damage to heart
  • Delayed blood clotting issues
  • Heart inflammation
  • Hemorrhage (internal bleeding)
  • Irregular heartbeat
  • Low blood pressure
  • Vomiting up blood

Vision and Eye Symptoms of Black Mold

Eyes are especially susceptible to black mold’s cytotoxic mycotoxins because of the vulnerability of their mucous membranes. Inflammation (watery, itchy, red eyes) is usually the first sign of exposure. Prolonged exposure can cause problems with vision.


  • Blurry vision and vision worsening
  • Eye damage
  • Eye inflammation and soreness
  • Jaundice (yellowing of the eyes)
  • Red eyes (bloodshot)

Skin Symptoms of Black Mold

Skin is the largest organ of the human body. It may not be as vulnerable as the mucous membranes of the eyes, mouth, or nose, but, along with respiratory problems, symptoms of black mold tend to show up immediately in the skin in the form of rashes, inexplicable sensations, and discoloration.


  • Crawling skin
  • Dermatitis (i.e. blisters, itchiness, rash, skin inflammation, etc.)
  • Jaundice (yellowing of the skin)

Immune System Symptoms of Black Mold

Black mold is pathogenic, which means it produces chemicals that suppress or overly-sensitize the immune system. This means that victims of black mold exposure may be more prone to illness, experience delayed healing, or be ultra-sensitive to stimuli (i.e. stress, certain foods, etc.).

Frightening Fact #2: Many immunosuppressive drugs are created from toxic molds.


  • Immunosuppression (dysfunction of the immune system)
  • Reoccurring infections

Reproductive System Symptoms of Black Mold

Black mold mycotoxins are also teratogenic, which means they can cause damage, developmental issues, and even birth defects to unborn babies in the womb. Not only are they teratogenic, but they’re also cytotoxic (damaging to cells), mutagenic (causing mutation to cells), and they inhibit protein synthesis of DNA and RNA. In other words, exposure to black mold is very concerning news if you’re pregnant or want to have children in the future.


  • Fetal development issues
  • Impotence
  • Infertility
  • Miscarriage

General Symptoms of Black Mold

In an effort to slow down the effects of black mold and protect your bodily systems, your immune system produces chloral hydrate (a sedative). This is why many victims complain of chronic fatigue or exhaustion. Another common complaint is a general feeling of being unwell or aches and pains that have no clear indication of “why” or “how”.


  • Abdominal pain
  • Aches and pains
  • Chest pain
  • Chronic fatigue
  • Cold- or flu-like symptoms (i.e. recurring colds)
  • Diarrhea
  • Drowsiness
  • Fever
  • Headaches
  • Joint pain
  • Malaise (general discomfort or feelings of being unwell)
  • Muscle pain
  • Nausea
  • Vomiting
  • Weakness

Commonly Misdiagnosed Symptoms of Black Mold


  • Coma
  • Hair loss
  • Hearing loss (also: tinnitus—buzzing or ringing in ears)
  • Hormonal imbalances
  • Increased appetite
  • Liver disease
  • Loss of appetite
  • Weight gain
  • Weight loss

Who is Most Susceptible to Black Mold?

Toxic black mold affects different people in different ways. Some people won’t experience symptoms as severe as what others experience. Children, the elderly, and people with weak immune systems are usually the most susceptible. Death from black mold exposure is more common among these types, as well.

Are you having trouble identifying whether or not your symptoms are due to black mold exposure?

First-time exposure may only produce the following symptoms:

  • watering, irritated eyes
  • sneezing
  • runny nose
  • nausea
  • vomiting
  • burning sensations in airways
  • a tightening in the chest
  • cough
  • nosebleed
  • fever
  • a long, painful headache

In the case of frequent exposure, black mold will cause:

  • similar, but more frequent (and sometimes more intense), symptoms as first-time exposure
  • even further difficulty (and discomfort) in breathing
  • sinusitis
  • chronic fatigue
  • dull, relentless aches in joints and sinuses
  • sudden onset of depression
  • neurological issues (especially in children)
  • pulmonary bleeding (especially in infants)

Once a person is no longer exposed to toxic black mold, most of their symptoms should gradually decrease. Some of the health problems caused by toxic black mold are permanent, though. For example, after a person has been exposed for a good amount of time, their immune system most-likely won’t be as strong as it once was, and they’ll be more sensitive to mold and mycotoxins in the future.

This is why it’s imperative for potential victims of black mold to speak up to their healthcare providers if they believe they’ve come in contact with mold of any kind. Not all medical professionals are trained to recognize these symptoms as evidence for black mold exposure. In most cases, individual symptoms are treated while the patient still lives and works in a mold-infested environment simply because their doctor did not ask the right questions. As symptoms worsen, the dosages of their medications are often increased or new medicines are introduced, which only masks the problem.

How to Get Rid of Black Mold

I’ve written on how to clean black mold before in an article titled “Symptoms of Black Mold,” which I highly suggest you read (as it contains even more information you’ll need if you suspect black mold exposure). I will borrow from there a few points about black mold clean up:

The first step in any situation involving any type of mold, is to find it and eliminate it or remove yourself from the affected home or work space entirely. It isn’t always necessary to identify the specific type of mold because all molds pose health risks, whether they are the “milder” allergenic molds or the “more potent” pathogenic molds, such as black mold. However, certain legal scenarios may require the use of a mold test kit or hiring a professional mold remediation team to do the testing for you, especially if you are a renter or a landlord. In addition, some patients are unable to receive the treatment they’re convinced they need because their doctors are unaware of the ins and outs of black mold health risks. Identifying the mold in their home may come in handy when confronting medical professionals about misdiagnosis, especially since a lot of the medical decisions are based on insurance coverage and patients are unable to go to the right specialists without formal referrals from their current doctors.

If black mold is suspect (or any highly-dangerous mold, for that matter), it is wiser to hire a professional mold remediation company to locate and clean up the mold. This is because black mold, especially, is a very hardy mold. It can survive even the harshest of environments and, unless its roots are destroyed, it will merely lie dormant until conditions are favorable again for regrowth. Also, most supplies available at reasonable prices to the public (gloves, breathing masks, etc.) do not adequately protect against infiltration from mold spores and mycotoxins. Furthermore, commercial mold-cleaning solutions can be both ineffective (if bleach-based) and sometimes more harmful to the skin, mucous membranes, and lungs than the mold itself. If remediation is not possible based on the severity of the mold growth, the budget of the victim(s), or the consent and willingness of the landlords, then it is best to move (or seek legal counsel).

The second step (after the mold is removed) is to commit to preventative measures in the home. All molds thrive in dark, damp, and relatively unclean areas. Keep the home bright with as much natural light as possible, dry (a dehumidifier may be necessary), and clear of dirt, dust, and food particles. Keep up with household maintenance (updates and filter-changes) on all appliances, water pipes, and HVAC systems.

The third step is to confront any health issues and begin a regimen of detox and natural healing. Mold and yeast thrive in bodies that are malnourished by diets high in sugar and processed foods. In order to detox your body from mold, you must first begin by cutting out sugars, fruits, processed foods, fried and greasy foods, dairy, meat, grains, mushrooms, and nuts that are well-known for their mold content, such as pistachios and peanuts. Adopt a habit of eating dark leafy greens in abundance, as well as plenty of garlic and other anti-inflammatory and anti-fungal foods. Allow a period of five to six hours between each meal and never eat just before bed. This permits the digestive tract to rest and the body to focus on healing instead of digestion. Consider anti-fungal supplements, such as Myco-ZX, as well. Lastly, increase sweat-inducing exercise, water intake, and sleep.


Understand that black mold’s mycotoxins are some of the most durable and resilient toxins on the planet. Ultraviolet light does not destroy them, nor do freezing temperatures. They are also not soluble in water. In a normal environment—like any average home—these mycotoxins can remain toxic for years. It would take temperatures as high as 500 degrees Fahrenheit (for 30 minutes or more) in order to destroy trichothecene mycotoxins, which is why many professionals advise victims to destroy any and all items that came in contact with black mold in order to make remediation successful.

In other words, if you have black mold, you have a very serious problem. The way you go about cleaning and removing it should be equally serious.

You are Drinking Mold in Your Coffee Mon, 29 Apr 2019 19:06:37 +0000 According to recent studies, Americans are drinking more coffee than ever before. In 2015, it was predicted that excessive coffee consumption would decrease, thanks to the invention of the coffee pod. This prediction, however, was a flop. Now, in 2019, over 80% of Americans drink coffee daily—that’s about 400 million cups a day—and many confess […]]]>


Is There Mold in Coffee?

The question shouldn’t be, “Is there mold in my coffee?” because study after study after study confirms that over 45% of coffees and coffee brands contain significant amounts of mold toxins. To date, there are over 60 sources producing 9.5 million tons of coffee beans per year for the world’s caffeine addiction. If the studies are true, that means that nearly 50%—almost half—of all the coffee in the world is infested with the disease-causing effects of mold. Furthermore, since researchers have yet to test more brands and sources, this means that the percentage could be even higher than 45%.

If consumers only had to worry about coffee mold spores or perhaps even just mold in coffee grounds, that would be one thing. Unfortunately, it’s the secondary metabolite (think: toxic “flatulence”) of fully matured mold that is present in coffee. This toxic mold flatulence, so to speak—otherwise known as a mycotoxin—is produced in varying levels of toxicity, depending on the type of mold.

While studies have revealed several types of mycotoxins and aflatoxins present in 45% of coffees, the most alarming finds, thus far, have been the following mycotoxins and coffee mold symptoms:

Aflatoxin B1. This is a well-known genotoxic hepatocarcinogen, which means it causes liver cancer.

Aflatoxin B1 will bind itself to a segment of DNA, forming a DNA adduct. These DNA adducts, especially in the case of Aflatoxin B1, make cancerous changes to liver cells. To put it plainly, when Aflatoxin B1 is permitted into the body, it switches liver cells into “cancer-prone” mode or full-blown cancer itself, especially if the consumer practices other erroneous health decisions (i.e. poor diet, lack of exercise, etc.).

Fumonisin B1 (FB1). This causes neuronal degeneration in the cerebral cortex, as well as an interruption of lipid synthesis in the brain.

Simply put, it damages the cells of the parts of the brain that are responsible for memory, attention, perception, awareness, thought, language, and consciousness. This is no small thing. Many victims of toxic mold complain of “moldy brain” or “mold brain fog,” but there are countless others who suffer more debilitating changes in cognition, yet they’re often misdiagnosed with mental illness.

In addition, the interruption of lipid synthesis means that the body’s ability to metabolize fat will become disordered. Once disordered, the body becomes imbalanced with less “good” fats (complex sphingolipids) and more “bad” fats (sphingoid bases and sphingoid base metabolites) on the cellular level. The “bad” fats can cause cancer, particularly of the liver and kidney.

Macrocyclic Trichothecenes. Like Fumonism B1 (FB1), this also causes neuronal death (i.e. kills very important brain cells). It also causes inflammation of the olfactory system. This means that, not only is the victim eventually suffering from disabled cognitive function, they’re also subjected to chronic rhinosinusitis, which denies them a proper sense of smell and comfortable breathing through the nose.

Ochratochin A (OTA). This is responsible for serious dopamine depletion and cell death within the brain.

Dopamine is one of the feel-good neurotransmitters that motivates a person’s mood, sleeping patterns, capacity for learning, motor control, working memory, and their ability to focus and concentrate.

Anyone living the stereotypical “American Dream” lifestyle most-certainly is experiencing significantly-low dopamine levels, marked by chronic fatigue or even bouts of depression. It comes as no surprise then that most “American Dream” enthusiasts are hooked on coffee. Coffee—or caffeine, rather—temporarily increases dopamine levels. In other words, it’s a drug that’s legal, infested with mold, and abused on a daily basis by millions of people.

T-2 Toxin. Like all of the above mycotoxins found in coffee, the T-2 toxin causes neuronal death. Not only does it destroy brain cells, it also causes alimentary toxic aleukia, which is a mycotoxin-induced condition characterized by diarrhea, hemorrhaging, leukopenia (susceptibility to devastating infection), nausea, skin inflammation, vomiting, and sometimes even death. In the 1940s, for example, thousands of USSR citizens within the Orenburg District (10% of the total population of that region) ingested T-2 infested grains and died after developing alimentary toxic aleukia. Since research has uncovered the T-2 toxin in coffee, this begs the question: “Are the addictive benefits of coffee worth the risk?”

Why Would There Be Mold in Coffee?

There are several reasons why mold is guaranteed to be in most coffees on the market, but probably the most obvious reason is that coffee crops are raised in tropical climates. Mold species vary by climate and the type of food source available. The warmer and wetter the climate, the greater the variety of mold type and mold growth. Because coffee crops are tropical, they are exceedingly susceptible to mold growth and, subsequently, the disease-causing secondary metabolites known as mycotoxins and aflatoxins.

Secondly, mold spores teem in the millions—if not billions—in any given environment, which makes it next to impossible to ensure coffee beans—undergoing the typical processes in the typical processing environments—will be mold-free. This is especially an issue when coffee beans are spread out to dry in large open areas where coffee mold spores are sure to land and take root among the beans.

Thirdly, those “typical processes” and those “typical processing environments” make for a rather unavoidable cesspool of mold proliferation.

Sadly, not many consumers are aware of the process by which coffee can—and usually does—harbor and proliferate the growth of mold. For instance, the main catalysts to mold growth and mycotoxin development in coffee bean production is the fermentation process, length of storage, and storage materials.


Once harvested, the ripe and even overripe coffee cherries are pulped (crushed open) to reveal the inner coffee bean. Even after removing the skin and pulp, the coffee beans are still tightly encased in their mucilage. The mucilage—a slimy sheath that surrounds the coffee bean—is comprised of carbohydrates, simple sugars, and protein—all of which significantly whet mold’s appetite.

The mucilage-removing fermentation process that the slippery beans undergo involves cement tanks, water, and 16 to 36 hours of fermentation. While fermenting the coffee beans may remove this unwanted slimy sheath that would otherwise inspire mold growth, the water, warmth, and fermenting time only encourages mold growth and mold maturation even more.

This is a common problem that coffee producers worldwide readily admit, but because the fermentation process greatly impacts the taste of the coffee, it is the main processing choice of nearly 100% of all specialty coffee producers.


Coffee is a crop like any other. Similar to grain and corn, coffee beans are harvested, processed, and stored for long periods of time in hot, damp conditions. In the United States alone, storage-induced toxic mold growth is a serious and chronic concern among agriculturists. Nuts, corn, grains, and coffee are all subjected to storing conditions that comfortably host and foster the development of mature molds. Even the shipment of coffee beans, whether by land, sky, or sea, poses a possible threat of mold growth since many shipping containers and trucks cannot combat heat and moisture adequately.

Storage Materials

When coffee beans are shipped from the producer to departments of the brand company, they most commonly arrive in large burlap sacks. The brand company then redistributes the coffee beans in their signature container—usually plastic or laminated barrier film—and they are stored in trucks or shipping containers as they make their way to stores across the country.

The problem with burlap sacks is that they are prone to developing mold themselves. Burlap is made from the skin of the jute plant. Like cardboard, jute fabric fibers are made of cellulose, which provide the most toxic molds all the nutrients they need to take root and grow.

If there are already coffee mold spores present, then the brand company’s plastic or laminated barrier film container only makes matters worse. The mold is kept out of direct light, shielded from severe temperature changes, and any and all moisture is locked in with the moldy coffee. It’s the perfect environment for growing even more mold.

So, Does Your Coffee Have Mold?

There are several indications that you might have mold in coffee. Was there ever a time that you accidentally forgot to toss out the filter from your last brew and a few days passed? If you noticed the smell or visual hint of any mold in coffee grounds within the last filter, it’s guaranteed that the batch of coffee you purchased was already moldy before you brought it home.

Another indication would be a moldy smell coming from your coffee maker, regardless of regular filter changes. Statistically, over half of all coffee brewers are a breeding ground for mold.

Some may be able to detect this mold in their coffee, but many do not smell or taste the mold or mycotoxins in their coffee beans.

And, lastly, you may have become aware of coffee mold symptoms that affect your health. Did you know that ingesting coffee mold spores can trigger allergies? That’s right—just one cup of moldy coffee can cause congestion, coughing, headaches, sneezing, and watery eyes. Even the sudden onset of flu-like symptoms and upper respiratory infections can stem from the consumption of moldy coffee. Gastrointestinal issues, such as bloat, diarrhea, loose stool, cramping, can all be signs of mold in coffee, as well.

So, what are the solutions?

“Mold-Free Coffee” Options

Coffee raised and processed organically at high altitudes is more likely to be as close to mold free coffee as you’re going to get. This is because high altitudes produce drier climates. Mold has very little chance of taking root and growing in those conditions, even if the coffee bean is wet-processed (fermented). It’s not the ideal, but it’s an option.

Why Do You Drink Coffee?

If you love someone, you tend to want to know everything you can about them. If that’s the case, then why is it that you don’t know everything about your most beloved beverage—coffee? If you’re a serious coffee connoisseur or you’re one of the many who feels that they can’t function in the morning without a hot, steaming cup of coffee, then you need to be better informed about what it’s doing to your body.

Even back in the 1860s, it was common knowledge that coffee—caffeine more specifically—was a harmful indulgence that injuriously excited the nerves, causing an aftereffect of exhaustion and the paralysis of mental and physical abilities. There were countless temperance movements that warned men and women of all ages to reduce their coffee consumption or avoid coffee altogether. As early as 1863, health enthusiasts were concerned about the toxins in coffee, especially mold.

Today, people are catching on to the fact that coffee is not necessarily the helpful friend it’s generally perceived to be. There is new evidence that suggests women shouldn’t drink coffee at all. There are even celebrities who avoid coffee and warn others of the negative impact it has on the mind and body.

Check out news staffer James de Villiers’ 14-day “I Gave Up Coffee” experience. It might surprise you to discover that you can relate to his concluding remark: “Coffee became a crutch to make up for other things in my life which were out of balance.”

Consider Healthy Alternatives to Coffee

Mold in coffee is most assuredly dangerous, but the caffeine in coffee and other beverages is also damaging long-term. Thankfully, there are healthy alternatives that not only keep you safe from coffee mold symptoms, they are also just as equally tasty and comforting as that hot cup’a joe.

Mold Dust Tests – ERMI Testing Tue, 23 Apr 2019 05:30:57 +0000 Mold is a common health problem plaguing many homes across the globe, irrespective of financial status or location.

Mold is a common health problem plaguing many homes across the globe, irrespective of financial status or location. A homeowner or renter who suspects mold can quickly become overwhelmed and stressed about where to start and what to do. So, what should you do when you think you have mold in your home? Mold is a serious issue, and safely detecting mold and the types of mold is often the first step in determining the best course of action. This is why it’s beneficial to use the Environmental Relative Moldiness Index (ERMI) method of testing mold.

What is an ERMI test?

One of the easiest, least invasive, and relatively inexpensive ways to test for mold is through a test called Environmental Relative Moldiness Index (ERMI). This type of test samples the dust in your home for the presence of mold. This dust specimen is examined utilizing mold-specific quantitative polymerase chain reaction (MSQPCR), a method that evaluates mold species, and is then compared to a national database to reveal your home’s relative moldiness index (RMI).

What does that mean for those of us who don’t speak scientific snobberism? In short, this test uses the analysis of settled dust in homes and buildings to determine the concentrations of the DNA of the different species of molds that are present. The makers of the ERMI mold testing method have assembled a database of different molds–36 to be exact–that they refer to when defining and scoring a home or building’s mold population. The results are then compared to a thousand or more homes in the U.S. Environmental Protection Agency’s (EPA) national database, which allows current–and potential–home and business owners to evaluate the moldiness of their buildings in comparison to other similar structures throughout the United States. They also differentiate between which molds are caused by water damage (WDB) and which molds aren’t. This can be very helpful for homeowners because it takes out the guesswork and enables them to know what their next step should be in mold remediation. Unlike some mold kits and methods, the ERMI method identifies precisely what molds are in the building and measures their quantity with a purported 100% reliability.

How do you collect a mold sample for the ERMI?

Most mold testing kits are dependent on air samples. While this can be helpful in many cases, it is not the ideal method for obtaining samples. The ERMI, however, relies on the dust from carpets. Carpet dust acts as a reservoir for mold spores. There is no Hoover or Bissel on earth that can fully eliminate even a month’s-worth of embedded microscopic mold spores from carpet fibers, which is why carpet dust is a greater representation of mold levels over time versus short-term air samples.

Below are only brief, generalized instructions for carpet dust sampling. The EMLab P&K website explains their ERMI mold sampling method in greater detail, if needed.

  • Dust samples are collected by vacuuming approximately 2 square meters (or 21 square feet) in the living room and 2 square meters (or 21 square feet) in a bedroom for 5 minutes each with a Mitest™ or DustChek™ sampler-fitted vacuum directly adjacent to the sofa or bed, respectively.
  • Ship the dusted cassettes to the laboratory (EMSL Analytics, EMLab P&K, EnviroBiomics, Inc., Mycometrics) for overnight delivery. (If the samples are stored before analysis, precautions should be taken so additional mold growth in the sample is avoided.)

What is a safe ERMI score?

After receiving an ERMI test from a qualified mold inspector laboratory, it is time to evaluate the results. The ERMI Safe Life website explains the nuances of ERMI scoring most succinctly:

“The ERMI score is the difference between Group 1 (bad) and Group 2 (good) molds. ERMI scores range between -10 (really good) and +20 (really bad.) Most people with Chronic Inflammatory Response Syndrome (CIRS) cannot tolerate an ERMI score above +2 without becoming ill. However, there are many individuals who have been very ill and are extremely sensitive. They often need an ERMI score as low as -1 to continue recovery. You will need to listen to your body because an ERMI score that is safe for most people, may not be safe for you. You will need to learn what ERMI score is safe for you.”       

Note: A great suggestion is to share the documentation with a health provider to better understand one’s health issues in correlation with their home’s ERMI mold score. In nearly 100% of all cases, a doctor is unable to even diagnose mold sickness without a reliable mold test from a reliable mold-testing laboratory.

How much does an ERMI test cost?

In general, the ERMI test sampling kits, including the laboratory services, cost around $300 or less. (If additional parts are needed for dust collection, the DustChek™, for example, is an additional cost of $6.50.)

If a simpler collection method is preferred, Mycometrics ERMI mold test is the least complicated because it uses a Swiffer-type AccuCloth Kit for only $290. Mycometrics also offers an affordable HERTSMI test option for $155, using the same easy collection method.

As for the ease of finding an ERMI test Amazon might offer, the only one listed on the site is an ERMI mold test that is currently (as of 4/16/2019) unavailable. Pricing information is also not available on Amazon at this time, though it may be beneficial to check at a later date.


The Environmental Relative Moldiness Index (ERMI) method of testing and indexing mold is quickly becoming the more superior method available on the common market. It’s built a groundbreaking reputation among mycologists, victims of mold, health providers, and even property owners over the years. Because ERMI’s automated analysis provides for rapid, reproducible results that can be accurately interpreted, patients, prospective home-buyers, industrial hygienists, and mold remediators have a lot to look forward to in the future. The promise shown in the level of ERMI test reliability is quite astounding.

If you have used an ERMI mold testing kit, please share your experience in the comments below. Your personal experience is highly valuable to other readers who are battling mold problems.

What is Concrobium Mold Control?

In several articles on the web, readers have been advised on how to create their own mold killer products from natural ingredients, such as borax or essential oils. There is even advise on how to concoct a DIY laundry detergent, as well as some insight into the effectiveness of antifungal supplements and antifungal diets. This is quite possibly because many commercial mold removal products are ineffective and equally—if not more—hazardous to the consumer’s health. Over the past few years, however, one product in particular—Concrobium Mold Control—has held the attention of mold remediation experts. Could this product be as effective against mold as it claims to be?

Currently, Concrobium offers three mold removal products, two of which target superficial and embedded mold stains, as well as provide a mold-preventing layer on a variety of surfaces, including decks and housing exteriors. While all three products contain the same chief ingredients and serve similar purposes, the only product being explored today is the one that’s been specifically hailed as a mold killer: Mold Control.


The validity of their claims and the foundation of your trust as consumers in this specific mold killer and Concrobium’s other mold removal products must be based on the efficacy of their ingredients, which is precisely what will be discussed next.

Concrobium Mold Control Ingredients

Concrobium Mold Control is a patented solution comprised of purified water, sodium carbonate (washing soda), sodium bicarbonate (baking soda), and trisodium phosphate. Together, this unique, tri-salt (three salts) polymer is intensely alkaline (not acidic), which holds great advantage over mold.

Mold mirrors the human body in that it prefers a specific balance between acidity and alkalinity. Both thrive between 6.5 and 7.5 on the pH scale, but mold can sustain itself between level 2 and 9. Anything below 6.5 is considered acidic, while anything above 7.5 is considered increasingly alkaline. Concrobium Mold Control reaches a pH balance of 11+, which (considering the highest level is a 14) makes this quite a mighty alkaline mold killer solution. While mold may lie dormant for a time in an acidic environment, it cannot survive long in one of high alkalinity, which is one reason why so many antifungal diets prescribe to alkaline foods.

Furthermore, once this tri-salt polymer is sprayed on the mold itself, it begins to dry. The solution’s molecules dehydrate and pull in on each other, which crushes the existing mold spores and their colonies. Even when the solution has dried and remains in place over the mold-affected area for several months, it continues to leave a lasting alkaline barrier that prevents the possibility of mold regrowth. This aligns precisely with what the company claims.

How to Use Concrobium Mold Control

Getting rid of mold with Concrobium Mold Control is so simple that, even in their 3-minute instructional video, it takes only about 40 seconds for them to explain how to clean mold with their product. The other 2+ minutes are dedicated to general mold awareness and methods to eliminate moisture.

As always, if you find mold in your home and you intend to use any type of product on it, you will need to be sure you have taken the necessary steps to not only begin the process of getting rid of mold, but also the process of preventing mold in the future. This begins with moisture control, which you can read about here.

Once you have remedied any excessive moisture and removed the area of dirt and other debris, you can now focus on how to clean mold with Concrobium Mold Control:

Step 1: Apply a thin, even layer over the mold-affected area.

Step 2: Allow to dry completely.

Step 3: With a dampened cloth or brush, scrub the surface to clean away any remaining mold stains and residue.

Step 4: If necessary, repeat on tough mold infestations.


Concrobium Mold Control Reviews

Years ago, a writer at MoldBlogger received Concrobium Mold Control to test on mold. Unfortunately, no moldy opportunity reared its ugly head. Disappointment in a lack of a mold problem might seem a little ironic, but the chance to discover a commercial mold killer that actually works would have been a great find.

Thankfully, there is a multitude of other consumers who have provided ample testimony over the years. Most swear by the efficacy of Concrobium’s claims, while a small number have raised questions about the ingredients themselves. Some have falsely assumed that Mold Control is merely a bottle of water and baking soda, but that simply isn’t true. As stated prior, Concrobium has devised a specific measurement of three different salts. Without that tri-salt polymer combination, Mold Control would not have the same alkalizing effect that it does. Baking soda alone could not at all achieve the success that thousands have claimed they’ve had with this solution, which is why you won’t find an article on MoldBlogger that claims that only baking soda and water will solve your mold problems.

Where to Find Concrobium Mold Control

Concrobium Mold Control is available from hardware and farm supply stores, such as Home Depot, Lowes, Ace Hardware, and Tractor Supply. You can also purchase it from a third party on Amazon. Depending on what the size of the infestation and the mold-cleaning methods you choose, you will want to read the instructions carefully. Some areas and methods call for nothing more than a sponge and their 32. oz. spray bottle. Other, more expansive cases, may call for the need for a Concrobium Mold Control fogger.

Concluding Thoughts on Concrobium Mold Control

While there is no guarantee that you will have success with Concrobium Mold Control on every mold situation you encounter, the ingredients and testimonies themselves support the idea that this is the very first commercial mold killer that can live up to its claims. As mold removal products go, the simple ingredients in Concrobium Mold Control far surpass any others that have been reviewed by mold experts who care not only about eliminating mold, but also protecting their readers from the harsh effects of mold-killing chemicals. Not only are they less harmful than other mold killer products that usually only combine bleach, they’re effective where it matters most—the very cells and roots of the mold.

If you’re willing to give Concrobium Mold Control a try on your mold problems, please share your experience in the comments below. Your testimony with this and any other mold-fighting solution on MoldBlogger is very important to other readers who are suffering from mold.

Snow Mold in Your Lawn? Tue, 26 Mar 2019 01:03:31 +0000 As winter melts away into spring, things may start to reappear in your yard that was previously hidden by winter’s thick blanket of snow.

As winter melts away into spring, things may start to reappear in your yard that was previously hidden by winter’s thick blanket of snow. You may rediscover that tool that was not put away before the first significant flurries, or just the welcome signs of spring as your perennial bulbs begin to push through the surface. An unwelcome sight, however, may be the appearance of a fungal lawn disease called snow mold.

What is Snow Mold?

Snow mold grows from the spores of two types of fungi… a gray mold called Typhula blight, and pink variety called Microdochium nivalis, (also known as Fusarium patch). These molds are responsible for causing the lawn disease which resembles a spider-web like white substance. Snow mold begins growing when temperatures start to warm enough for the fungi to thrive. The pink snow mold can flourish from 32 degrees up to 60 degrees, as long as your lawn is damp, while the gray mold can grow from about 32 degrees to 45 degrees fahrenheit.

Is Snow Mold Dangerous to Your Lawn?

Though snow mold can cause your lawn to look unattractive, the fungal growth is typically not a serious concern and will dry up as the weather warms and the sun dries out and kills the infected lawn. To accelerate this process and get rid of the snow mold earlier, there are several things you can do:

  • You can spread out the snow mold with a rake (being careful to not damage the grass trying to grow). This will help get air flow to the infected area and dry it out faster.
  • Once your lawn is dry enough you can mow it shorter than usual. Tall grass can retain more moisture, which contributes to the fungal growth. Continue mowing the lawn in this manner until you notice the mold is no longer growing.

Snow Mold Prevention

There are a few things you can do to try to prevent the unsightly growth of snow mold:

  • In late fall be sure to mow your grass to a short height and then rake up and bag the grass clippings and any leaves that are collecting in your lawn. This organic matter can trap the moisture and create a perfect environment for the snow mold fungal growth to take off as the snow melts and temperatures get to the right levels.
  • Do not use a nitrogen fertilizer in the fall if you have had issues with snow mold.
  • If you have larger piles of snow in certain areas, it is a good idea to spread out the snow so that it melts more quickly and doesn’t retain the moisture as long in those spots.

Snow mold is not usually a serious concern, but it can sometimes persist into late summer and fall if the weather remains damp and cool enough. If this happens it can do more damage to your lawn. Years with earlier, deeper snows often result in more snow mold growth than the winters that are colder and bring less snow. This is because the early snow blankets the ground and protects the fungus from harsher temperatures.

Have you ever had snow mold in your lawn? How long did it last and what did you do about it?
