Black Mold Allergy: Symptoms, Diagnosis, Treatment, and Safe Mold Removal

Black mold allergy is the common name for a reaction to mold fungi that grow in damp areas and can appear dark, gray, greenish-black, or almost black. Medically, it's not just the color of the stain on the wall that's important, but the actual presence of mold growth, dampness, and inhalation of spores or fungal fragments, as different types of mold can cause similar allergic and irritant symptoms. [1]

The term "black mold" is often used for Stachybotrys chartarum, a greenish-black mold that can grow on materials with high cellulose content, such as drywall, paper, fiberboard, and other damp building materials. The Centers for Disease Control and Prevention emphasizes that Stachybotrys chartarum requires persistent moisture to thrive, such as from leaks, condensation, water intrusion, or flooding.[2]

It's important to immediately separate proven risks from scary myths. Mold can indeed cause nasal congestion, runny nose, coughing, wheezing, eye irritation, skin rashes, and asthma exacerbations, but the popular term "toxic black mold" often exaggerates the role of mold color, creating the false impression that only one type of mold is dangerous and others can be ignored. [3]

The World Health Organization considers indoor dampness and mold to be important factors in indoor air quality. Its guidelines indicate that indoor microbial contamination is associated with an increased prevalence of respiratory symptoms, allergies, asthma, and immune system disorders, and that the primary prevention method is preventing persistent dampness and microbial growth on interior surfaces and within building structures. [4]

For the patient, the key practical takeaway is this: if mold is visible or felt in the home, it should be removed and the source of the moisture eliminated, rather than focusing on determining whether it's black or not. The Centers for Disease Control and Prevention clearly states that if Stachybotrys chartarum or other types of mold are found in a building, they should be removed, and the type of mold typically doesn't need to be determined to determine whether to remediate the problem. [5]

Term	What does it mean?	Why is it important?
Black mold	A common name for dark mold on walls, ceilings, furniture, or building materials.	Color does not determine all risk
Stachybotrys chartarum	A greenish-black mold often associated with damp drywall and paper	Requires constant humidity
Mold allergy	An immune reaction to mold spores or fragments	May cause rhinitis, conjunctivitis and asthma
Irritation from mold	Non-specific irritation of eyes, nose, throat, skin, or lungs	It may even be without allergies.
Mycotoxins	Substances that some molds can produce as they grow	The term is often misused in everyday life.
Dampness	A condition without which mold usually does not grow indoors	The main point of prevention
Mold removal	Physical cleaning and removal of moisture source	More important than defining the species

Why does black mold cause symptoms?

Mold reproduces by spores, which can become airborne, settle on surfaces, and, in the presence of moisture, form new colonies. It's impossible to completely eliminate all spores from a room because mold fungi are ubiquitous, but the problem begins when spores land on a damp surface and begin to actively grow. [7]

In allergies, the human immune system overreacts to mold allergens. The American Academy of Allergy, Asthma, and Immunology explains that when mold spores are inhaled, a sensitive person may experience sneezing, itchy and watery eyes, a runny nose, nasal congestion, and itchy nose, mouth, or lips. [8]

Even if a person doesn't have a true allergy, mold and dampness can irritate mucous membranes. The Environmental Protection Agency notes that mold produces allergens and irritants, and inhaling or touching mold can cause allergic reactions in sensitive individuals and irritate the eyes, skin, nose, throat, and lungs even in people without allergies. [9]

Mold is especially important for asthma. The Environmental Protection Agency notes that mold can trigger asthma attacks in susceptible individuals with asthma, and the National Institute of Environmental Health Sciences indicates that exposure to mold can increase the risk of developing asthma or worsen its symptoms, especially in young children. [10]

Black mold is not a separate "magic" category of allergen. The Centers for Disease Control and Prevention emphasizes that Stachybotrys chartarum and other molds can cause non-specific symptoms, but all types of mold in buildings should be considered equally in terms of potential risk and the need for removal. [11]

Mechanism	What's happening	Typical manifestations
Allergic reaction	The immune system reacts to mold allergens	Sneezing, runny nose, itchy eyes, nasal congestion
Irritation	Spores, mold fragments and volatile substances irritate the mucous membranes	Burning eyes, irritation, cough, discomfort in the throat
Asthma exacerbation	The bronchi react with spasm and inflammation	Wheezing, coughing, shortness of breath, chest tightness
Infection	Mold fungi attack tissue in people at high risk	Fever, difficulty breathing, lesions in the lungs
Hypersensitivity pneumonitis	Immune inflammation of the deep lungs after repeated inhalation of antigens	Shortness of breath, dry cough, fatigue
Psychological anxiety from the sight of mold	Fear of 'toxic mold' heightens perception of symptoms	Anxiety, insomnia, increased attention to sensations

Symptoms of black mold allergy

The most typical symptoms are similar to other inhalant allergies: nasal congestion, runny nose, sneezing, itchy nose, itchy and watery eyes, scratchy throat, coughing, and a feeling of mucus dripping down the back of the throat. The American College of Allergy, Asthma, and Immunology notes that mold allergy symptoms may include nasal congestion, runny nose, sneezing, eye irritation, coughing, wheezing, and itchy throat.[13]

Eye symptoms include redness, itching, watery eyes, and burning. They are often aggravated by cleaning damp areas, sorting through old items, contact with moldy fabrics, books, or carpets, or by being in a bathroom, basement, closet, or room with a leak.[14]

Bronchial symptoms may include coughing, wheezing, shortness of breath, and a feeling of heaviness or tightness in the chest, especially in people with asthma. If symptoms worsen at night, after rain, in a damp room, or when cleaning mold, this increases the likelihood of a connection with mold exposure. [15]

Skin manifestations may include itching, redness, irritation, or a rash. The Environmental Protection Agency and the Centers for Disease Control and Prevention list skin rashes as possible manifestations of mold exposure, but such rashes are nonspecific and can be associated with detergents, gloves, household chemicals, dust, mites, or other allergens. [16]

Seek immediate medical attention if you experience severe shortness of breath, wheezing, blue lips, confusion, severe weakness, high fever, coughing up blood, or a rapid deterioration in your condition. These symptoms should not be attributed solely to a "mold allergy," as they could indicate a severe asthma attack, infection, pneumonia, or another lung condition. [17]

Symptom	Possible explanation	Level of urgency
Sneezing and clear runny nose	Allergic rhinitis	Planned assessment
Itchy and watery eyes	Allergic conjunctivitis or irritation	Planned assessment
Sore throat	Irritation or mucus drainage	Planned assessment
Coughing while cleaning mold	Irritation, allergy or asthma	Need a review grade
Wheezing	Exacerbation of bronchial asthma or bronchospasm	Urgently if severe
Shortness of breath at rest	Dangerous respiratory condition	Urgent Care
Rash after contact	Allergy, irritation or other dermatitis	Dermatologist if recurrence occurs
Fever and deterioration of general condition	Infection or other disease	A doctor is needed
Hemoptysis	Not typical for a common allergy	Urgent medical care

Toxic Black Mold: What's True and What's a Myth

The term "toxic black mold" is often used inaccurately. The Centers for Disease Control and Prevention explains that some molds are toxigenic, meaning they can produce mycotoxins, but molds themselves should not be called "toxic" or "poisonous" as an organism; Stachybotrys chartarum should be treated the same as other types of mold growing in the home or workplace. [19]

Mycotoxins do exist, but the main proven risks to humans have historically been associated primarily with ingestion of contaminated food products, rather than with the common household inhalation of mold on the wall. The American Academy of Allergy, Asthma, and Immunology emphasizes that concerns about severe toxic effects of mycotoxins in the past were attributed to the consumption of contaminated crops, while "toxic mold syndrome" is often used to explain nonspecific symptoms without reliable evidence of causation. [20]

The story of Stachybotrys chartarum and pulmonary hemorrhage in infants has been widely discussed, but a proven causal link has not been confirmed. The Centers for Disease Control and Prevention states that a possible association between Stachybotrys chartarum and acute idiopathic pulmonary hemorrhage in infants has not been proven to date. [21]

This doesn't mean mold can be ignored. The correct position is both stricter and more sober: mold and dampness in the home should be addressed due to the proven link to respiratory symptoms, allergies, irritation, and asthma exacerbation, but there's no need to diagnose someone with "black mold poisoning" without proof simply because of fatigue, headaches, or "brain fog." [22]

It's a practical mistake to spend money on expensive "toxicity tests" instead of eliminating moisture. The Centers for Disease Control and Prevention points out that there is no medical test that can prove a link between Stachybotrys chartarum and specific symptoms, and even if mold is present in a building, it still needs to be removed and the moisture problem addressed. [23]

Popular statement	What does evidence-based medicine say?
All black mold is deadly toxic.	Color does not determine the degree of medical risk.
Stachybotrys chartarum always causes severe poisoning.	There is no proven association with most non-specific symptoms.
You must first determine the type of mold.	If mold is visible, it is more important to remove it and eliminate moisture.
If the air test is negative, there is no problem.	Short-term tests may not reflect actual exposure.
If the mold is black, you shouldn't touch it at all.	People in risk groups should not clean it themselves, but the mold should be removed.
Mycotoxins do not exist	They exist, but the everyday interpretation is often exaggerated.
Mold is not dangerous unless it is Stachybotrys chartarum	Any mold growth indoors indicates a moisture problem.

Who is at high risk?

People with asthma are at higher risk of worsening symptoms when exposed to mold. The Environmental Protection Agency notes that mold can trigger asthma attacks in sensitive individuals with asthma, and therefore such individuals should avoid exposure to mold. [25]

People with allergic rhinitis, hay fever, atopic dermatitis, and a family history of allergies may have a more severe reaction to mold spores. They are more likely to experience nasal congestion, itchy eyes, coughing, and prolonged symptoms when exposed to damp environments. [26]

People with chronic lung disease and immune suppression are at particular risk. The Centers for Disease Control and Prevention notes that people with immune suppression and chronic lung disease may develop fungal lung infections from mold, and people with asthma or chronic obstructive pulmonary disease may have breathing problems when cleaning up mold. [27]

Children, the elderly, and pregnant women don't necessarily have a "mold allergy," but they may be more vulnerable to respiratory effects in damp and poorly ventilated conditions. The World Health Organization links dampness and mold to an increased risk of respiratory symptoms, respiratory infections, and asthma exacerbations in residents of various types of buildings. [28]

Occupational risks should be considered separately: workers involved in flood repairs, cleaning, drywall removal, and maintaining old buildings, archives, basements, and ventilation systems may be exposed to higher levels of mold particles. The Centers for Disease Control and Prevention recommends respiratory, eye, and skin protection when removing mold, especially if the work is time-consuming or involves the destruction of materials. [29]

Group	Why is the risk higher?	What is important
People with bronchial asthma	Mold can trigger bronchospasm	Do not participate in mold removal
People with allergic rhinitis	Spores can contribute to nasal inflammation	Diagnostics and environmental control are required
People with chronic lung diseases	Higher risk of respiratory complications	Avoid damp rooms
People with immune suppression	Fungal infections are possible	Medical caution is required
Children	Increased vulnerability of the respiratory tract	Eliminate dampness in your home
Elderly people	Chronic diseases are more common	Reduce exposure
Repair and cleaning workers	High dose of spores and dust	Protective equipment and training
Residents after the flooding	Rapid mold growth on building materials	Rapid drying and removal of affected materials

Diagnosing Black Mold Allergy

Diagnosis begins not with an analysis of the wall, but with a medical history. The doctor will determine where the dampness is, when the symptoms began, whether they worsen at home, in the bathroom, basement, at work, after rain, after cleaning, or upon contact with moldy items, and whether they subside upon leaving the premises. [31]

Skin prick tests and blood tests for specific immunoglobulin E (IgE) to mold allergens are used to confirm allergic sensitization. The Mayo Clinic notes that skin prick tests use diluted amounts of common or suspected allergens, including local mold species, while blood tests can measure the immune response through specific IgE. [32]

A negative test does not always completely rule out a mold-related connection with symptoms. A 2024 review of mold allergy diagnostics notes that when an inhalant allergy is suspected, a prick test is typically performed, but a negative mold skin test does not rule out sensitization per se, because the quality and availability of extracts vary. [33]

If coughing, wheezing, and shortness of breath are present, it is important to evaluate asthma. This may include spirometry, a bronchodilator test, an asthma control assessment, a peak flow diary, and an analysis of the relationship between symptoms and exposure to damp environments. [34]

Routine air testing for "black mold" generally does not resolve the medical issue. The Centers for Disease Control and Prevention does not recommend routine air sampling for mold when assessing building air quality because there are no medical standards for mold concentrations in the air, and short-term samples may not reflect actual exposure. [35]

Method	What does it show?	When is it useful?
Medical history	Relationship of symptoms with dampness, home, work and cleaning	Always
Doctor's examination	Rhinitis, conjunctivitis, asthma, dermatitis or other condition	Always
Skin prick test	Sensitization to mold allergens	If you suspect an allergy
Specific immunoglobulin E	Allergic sensitization in the blood	When a skin test is not possible or a laboratory method is needed
Spirometry	Bronchial obstruction	For coughing, wheezing and shortness of breath
Symptom diary	Repeatability of connection with the room	When the picture is unclear
Inspection of the premises	Moisture source and visible mold growth	For prevention and repair
Routine air analysis	Often poorly associated with health risks	Usually not the main step

Differential diagnosis

An allergy to black mold must be distinguished from an allergy to house dust mites. Dampness not only supports mold growth but also creates a favorable environment for dust mites, so a runny nose, cough, and itchy eyes in a damp bedroom can be associated with several allergens. [37]

Symptoms can be confused with allergies to animals, pollen, cockroaches, household chemicals, fragrances, tobacco smoke, and air pollution. If complaints occur only in a specific room, after cleaning, or near carpet or upholstered furniture, the doctor should consider the entire environment, not just the visible dark spot on the wall. [38]

Respiratory tract infections can also look similar. A runny nose, cough, sore throat, and weakness could indicate a viral infection, sinusitis, bronchitis, or pneumonia, especially if accompanied by fever, purulent sputum, chest pain, or worsening general condition. [39]

Hypersensitivity pneumonitis is a distinct condition in which repeated exposure to organic antigens triggers immune inflammation of the deep lungs. It is distinct from a typical mold allergy and requires pulmonary evaluation, particularly if there is progressive dyspnea, dry cough, decreased exercise tolerance, and abnormal lung CT scans. [40]

Systemic complaints such as chronic fatigue, headaches, difficulty concentrating, and "brain fog" should not be automatically attributed to "black mold poisoning." The American Academy of Allergy, Asthma, and Immunology emphasizes that such claims surrounding "toxic mold syndrome" often extend beyond proven causation, although allergies, irritations, and infections from mold are real medical problems. [41]

Similar condition	Why does it look like this?	How to distinguish
House dust mite allergy	Runny nose, cough, asthma indoors	Tick tests, bedroom connection
Animal allergies	Itchy eyes, runny nose, asthma	Bonding with a cat, dog, or other animal
Viral infection	Runny nose, cough, sore throat	Acute onset, fever, contact with sick people
Sinusitis	Congestion and pressure in the face	Duration, pain, purulent discharge
Bronchial asthma without mold allergy	Wheezing and coughing	Spirometry, other triggers
Irritation from household chemicals	Burning eyes and throat	Relationship with cleaning products
Hypersensitivity pneumonitis	Cough and shortness of breath	Pulmonary examination
Infection in an immunocompromised patient	Cough, fever, changes in the lungs	Cultures, imaging, specialized diagnostics

Treatment for black mold allergy

The main principle of treatment is to reduce exposure to mold and eliminate dampness. The Mayo Clinic advises that the best way to manage allergies is to avoid triggers, although completely avoiding mold is impossible, so treatment typically combines environmental control and medications to relieve symptoms. [43]

For allergic rhinitis, a doctor may prescribe intranasal corticosteroids, antihistamines, saline nasal washes, and other treatments depending on symptoms. The Mayo Clinic notes that nasal corticosteroid sprays are often the most effective medication for upper airway inflammation associated with mold allergies. [44]

For eye symptoms, anti-allergy eye drops, cold compresses, and reduced exposure to the source of the spores may be used. If eye itching is accompanied by severe nasal congestion and cough, treatment should include the entire respiratory tract, not just the eyes. [45]

For bronchial asthma, a separate asthma treatment plan is necessary, as prescribed by a doctor: inhaled anti-inflammatory drugs, bronchodilators as indicated, education on how to deal with exacerbations, and control of triggers. The Environmental Protection Agency emphasizes that people with asthma should avoid contact with or exposure to mold. [46]

Allergen-specific immunotherapy for mold allergy is not feasible for everyone and depends on the specific allergen, the quality of the extract, and the clinical situation. The American Academy of Allergy, Asthma, and Immunology notes that the evidence base for mold immunotherapy is limited, and the most debated data concerns certain seasonal outdoor mold allergens, such as Alternaria alternata and Cladosporium herbarum. [47]

Clinical situation	Possible tactics	What is important
Mild rhinitis	Reduced contact, nasal lavage, antihistamines	Look for the source of dampness
Moderate to severe rhinitis	Intranasal corticosteroids as prescribed by a doctor	Regularity is required
Conjunctivitis	Anti-allergy drops and environmental control	Do not rub your eyes while cleaning.
Bronchial asthma	Asthma Treatment Plan and Mold Remediation	Do not remove mold yourself if you have severe asthma.
Skin rash	Examination, exclusion of other causes, local treatment	Not always associated with mold alone
Suspected infection	Medical diagnostics, sometimes antifungal therapy	Especially in cases of immune suppression
Suspected hypersensitivity pneumonitis	Pulmonary examination	Do not treat like a common cold.
Proven sensitization to individual molds	Consider immunotherapy with an allergist	Availability and evidence are limited

How to safely remove black mold

Removing mold without eliminating moisture is a temporary measure. The Environmental Protection Agency formulates the main principle very simply: the key to mold control is moisture control, and if mold is a problem, the damage must be cleaned and the source of the moisture eliminated. [49]

The Centers for Disease Control and Prevention advises that if mold is visible or odorous, it should be removed, even though knowing the exact type is not necessary. On hard surfaces, mold can be removed with household cleaners, soap and water, or a bleach solution no stronger than 1 cup household bleach per 1 gallon of water, but bleach should not be mixed with ammonia or other cleaning agents.[50]

People with allergies, asthma, chronic lung disease, or immune suppression should not participate in mold cleanup. The Centers for Disease Control and Prevention specifically states that these individuals are at risk for significant and severe effects from mold exposure and should not participate in cleanup. [51]

When cleaning, protective equipment is required: a respirator of at least a NIOSH Approved N95 standard, protective gloves, goggles, and skin protection. If the work is lengthy, involves removing moldy drywall, or involves large amounts of dust, the Centers for Disease Control and Prevention recommends more advanced respiratory protection, such as a half-mask or full-face respirator. [52]

Porous materials are often impossible to clean completely. Moldy drywall, insulation, ceiling tiles, carpets, mattresses, upholstered furniture, and paper materials may require removal after severe moisture exposure because mold grows within the structure, not just on the surface. [53]

Situation	What to do	What to avoid
A small stain on a hard surface	Clean, dry, remove moisture	Leave the source of the leak
Mold after flooding	Dry quickly and remove affected materials.	Living in a damp room without measures
Mold on drywall	Removal of a section is often required	Just paint on top
Mold in the bathroom	Improve ventilation, remove condensation	Keep the damp room closed at all times
Mold in a person with asthma	Do not clean up yourself	Work without a respirator
Using bleach	Dilute properly, ventilate	Mix with ammonia or acids
Large area of damage	Consider professional help	Spread spores throughout the apartment
Recurring mold	Look for leaks, cold bridges, ventilation	Endlessly treat the surface without repair

Preventing mold regrowth

Mold grows where there is moisture, so prevention begins with repairing the causes of dampness: leaking roofs, windows, pipes, condensation, flooding, poor ventilation, freezing walls, wet basements and constantly high air humidity. [55]

In rooms with high humidity, ventilation and exhaust ventilation are important, especially in bathrooms, kitchens, and laundry rooms. The World Health Organization emphasizes that preventing persistent dampness and microbial growth on interior surfaces and in building structures is the primary way to avoid adverse health effects. [56]

After a leak or flood, materials must be dried quickly. The longer drywall, wood, carpets, furniture, and insulation remain wet, the higher the risk of mold growth and the more difficult subsequent cleanup. [57]

In everyday life, regular dust cleaning, avoiding long-term wet carpets, controlling condensation on windows, adequate heating, using an exhaust hood when cooking, avoiding drying large amounts of laundry in an unventilated room, and quickly eliminating the smell of dampness help. [58]

If mold returns after treatment, the underlying moisture problem has not been eliminated. In this situation, it's important to look for a structural or engineering problem rather than swapping one mold treatment for another. [59]

Preventive measure	Why it works
Leak repair	Removes the main source of moisture
Extractor hood in the bathroom	Reduces condensation after showering
Ventilating the kitchen	Reduces moisture from cooking
Controlling condensation on windows	Shows the problem of humidity and cold
Quick drying after a leak	Prevents mold from taking hold
Removal of wet porous materials	Removes hidden mold reservoirs
Adequate heating	Reduces condensation on cold surfaces
Inspection under furniture and behind cabinets	Helps find hidden dampness
Do not paint over mold	Paint does not eliminate growth within the material
Control of damp odor	Helps to identify hidden problems

Frequently asked questions

Is it possible to be truly allergic to black mold? Yes, in sensitive individuals, mold spores can cause allergic rhinitis, conjunctivitis, and asthma exacerbations, but medically it's more accurate to talk about an allergy to mold allergens, not just to the "black" color of the mold. [61]

How is Stachybotrys chartarum different from other molds? It's a greenish-black mold that grows on damp, cellulose-rich materials like drywall, paper, and fiberboard, but if found in your home, it should be removed using the same principles as other types of mold. [62]

Is it necessary to test the air to determine whether mold is dangerous? In most household cases, no: The Centers for Disease Control and Prevention does not recommend routine air sampling for mold because there are no medical standards for mold concentrations in the air, and short-term test results are difficult to interpret in terms of health risks. [63]

What are the most common symptoms? The most common symptoms include nasal congestion, runny nose, sneezing, itchy eyes, cough, wheezing, sore throat, and skin rash; people with asthma may have more severe breathing symptoms. [64]

Can black mold cause asthma? Dampness and mold have been linked to worsening asthma, and some evidence suggests an increased risk of developing asthma, especially in children, so mold in the home shouldn't be considered merely a cosmetic problem.[65]

Is it true that black mold causes lung bleeding in infants? The Centers for Disease Control and Prevention notes that a possible link between Stachybotrys chartarum and acute idiopathic pulmonary hemorrhage in infants has not yet been proven. [66]

What tests are needed for a person with a suspected mold allergy? Typically, a medical history, physical examination, skin prick tests, and a blood test for specific immunoglobulin E to mold allergens are used; if cough and shortness of breath are present, asthma is also assessed. [67]

Can mold allergies be treated with pills alone? Pills and nasal sprays can reduce symptoms, but without removing mold and eliminating moisture, symptoms often return because the source of allergens remains indoors. [68]

Who shouldn't clean up mold themselves? People with mold allergies, asthma, chronic obstructive pulmonary disease, other chronic respiratory diseases, immune suppression, and chronic lung diseases should not participate in mold cleanup. [69]

When is urgent care needed? Urgent care is needed if you experience severe shortness of breath, wheezing, severe weakness, blue lips, confusion, high fever, coughing up blood, or a rapid deterioration in your condition, as it may not be a common allergy, but a severe respiratory illness or infection. [70]

These theses converge on one point: black mold shouldn't be ignored, but it shouldn't be turned into a mystical diagnosis either. A proven approach is to confirm allergies based on symptoms, monitor asthma, rule out infections in at-risk individuals, and eliminate the source of dampness in the room. [71]

Result

A black mold allergy most often refers to a reaction to the mold spores or fungal fragments, rather than to the black color of the stain itself. Symptoms may include a runny nose, nasal congestion, itchy eyes, coughing, wheezing, throat irritation, and skin rash.[72]

Stachybotrys chartarum is a real species of greenish-black mold that grows on constantly damp cellulose materials, but the Centers for Disease Control and Prevention emphasizes that all types of mold in buildings should be treated equally in terms of removal and potential risk.[73]

The main proven risks of dampness and mold are respiratory symptoms, allergies, irritation, and worsening of asthma. The World Health Organization considers preventing persistent dampness and microbial growth the primary way to protect the health of residents. [74]

Diagnosis in a patient is based on a history of symptoms, physical examination, skin prick tests, blood testing for specific immunoglobulin E, and an assessment of asthma associated with coughing or shortness of breath. Routine air testing for "black mold" usually does not answer the medical question and is not a substitute for moisture removal. [75]

Treatment includes mold control, dampness control, medications for allergic rhinitis and conjunctivitis, a comprehensive asthma treatment plan, and caution for people with immune suppression or chronic lung disease. If mold is visible or smells damp, it should be removed and the source of moisture eliminated. [76]
