How Many Types Of Black Mold Are There

Can Black Mold Spread From House To House

The Different Types of Black Mold

Yes. If you have had mold in your old house and youre moving into another space, it is possible to cross contaminate this new environment.

Because mold spores are not visible to the naked eye, it is hard to tell which surfaces are contaminated. Therefore, the mold has to be completely cleaned before you renovate or move to a new home.

How Does Black Mold Form

The main reason behind the formation of black mold is moisture, which can be caused by several things, such as, water leakage, lack of proper ventilation, flooding, irregular maintenance, humidifiers, condensation, clogged-up gutters, damp clothes, humid basements, or even water accumulation around the foundation of your house.

Black Mold Causes Severe Side Effects

Black mold emits something called mycotoxins. Mycotoxins are irritants that black mold and other mold types give off. When these irritants are inhaled, the person can quickly experience negative side effects. These can include side effects ranging from mild irritation to permanent brain damage.

When you are exposed to these irritants for a prolonged period of time, the side effects worsen. This means that the longer you go without finding the black mold in your home, the worse off you and your family can be.

These side effects are certainly unpleasant and dangerous for adults to be exposed to, but others are at even more risk. Children and senior citizens are at particularly high risk when it comes to black mold. With weakened immune systems and strength, these age groups could experience a fatal event if exposed for prolonged periods of time.

Black Mold Eats Cellulose

One important thing to remember is that it is attracted to cellulose. Wood contains this black mold food, so it will commonly be found growing on wood around the home. Other materials that contain cellulose include drywall, wallpaper, and even some paint. So, black mold could easily also be found on the walls and ceiling, depending on the composition of them in your home.

How To Test For Black Mold In Your House

The first step in figuring out if you have mold in your house if it is not visible to the naked eye is by smell. Since mold grows in wet and damp locations, it could be hidden behind a wall, floor or ceiling. A musty, earthy odour will permeate around building materials.

Basements and crawlspaces are places that promote black mold growth, especially if there has been flooding due to heavy rains or snowmelt. If mold issues are not dealt with in these less-trafficked areas, mold can continue to grow and spread, and affect the indoor air quality and the health of you and your family, in your entire house.

Black mold in attics is also a problem for houses that have leaky roofs or are not properly weatherproofed or insulated.

If you discover black mold in your home, it is recommended that you get a mold inspection from a certified professional. If it is present then mold testing can let you know if the black mold in your home is toxic or non-toxic to ensure your safety. Hiring a mold removal company would be the next step.

Create A Bleach Mixture

If the black mold growth in your home is small enough for you to treat alone, a simple mixture of bleach and water can help. Add one cup of bleach to one gallon of water and apply it to the moldy spots. You can also find commercial black mold removal products.

Apply the cleaner to the mold spot and scrub away the growth. Be sure to dry the area thoroughly when youre done.

Do NOT mix bleach with ammonia. This combination can create toxic fumes that are far more dangerous than any mold youre trying to clean.

Mold Testing To Test Or Not To Test

Black mold, or Stachybotrys mold, is generally greenish-black and slightly slimy or wet, but can also look gray with a powdery texture. Other molds may look very similar. This is why it is nearly impossible to tell the type of mold by appearance, smell or location. The only way to definitively identify a mold species is under examination of a microscope. Testing can sometimes be costly, depending on the circumstances, and isnt necessary in every situation. Official testing is often sought for real estate transactions or insurance purposes. Many types of mold can cause health problems therefore, if visible mold is present in your home or building, you should arrange to have it removed and remediated, no matter what type it is.

Molds come in all shapes, sizes, and colors, and while some may think that color can serve as an identifying characteristic, unfortunately, it is not. The main means of identifying molds involve looking closely at the structure, spore, and growth morphology, which isnt easily done without access to a lab. Color isnt a good distinguishing characteristic of mold or toxicity because one patch can have multiple colors or change color for several reasons. Some factors that affect mold color are:

  • Food source
  • Humidity level
  • Light exposure

Bread Mold: How To Identify Types Of Mold

Mold Guide for Homeowners

Bread mold is a type of fungus and is therefore eukaryotic and multi-cellular. Mold cells are present in a long filamentous structure called a hypha.

The mold cells are connected via pores in the septa between cells and are surrounded by a tube-shaped cell wall. A collection of hyphae is called a mycelium and is a single organism.

How Can You Be Exposed To Black Mold

You can be exposed to black mold, or any species of mold, by breathing in microscopic mold particles in the air, or through consumption of food that contains it.

Stachybotrys is unique because its spores are sticky and easily adhere to a surface when the mold colony dries. They are not regularly found in the air unless the mold colony has been disturbed. Though its spores are not readily airborne, black mold can produce other harmful contaminants more easily found in the air .

A disruption to a black mold colony can be as simple as slamming a door, opening a window or knocking into contaminated furniture. More force is required for Stachybotrys spores to become airborne, as compared to other commonly found indoor molds .

Determine If There Is A Smell

Another way that you can identity black mold is by the smell. This will be harder for those that dont have a trained nose. However, most mold smells the same. You should be paying attention to the smell of certain areas of your home. If there is a musty or mildew smell, theres a good chance that you have mold somewhere in your home.

You should follow these smells as best that you can, and then use visual and texture clues to determine if the mold is indeed black mold.

    • Itchy and red eyes
    • Respiratory irritations

    Those with asthma and other breathing problems must be extra careful. The mold spores are enough to trigger an attack. If you inhaled the mycotoxins, the effect would be much worse.

    The same goes for immunocompromised individuals. They are at a higher risk of developing an infection when exposed to black molds for long periods.

    Aside from adults, infants and children are also vulnerable when exposed to black molds. Its actually a risk factor for asthma among children.

    If you suspect that youre experiencing black mold poisoning, you should seek medical care right away. Youll undergo a blood test and skin prick test to determine if you have an allergic reaction to black molds. The doctor can also provide prescriptions to ease the symptoms. Ultimately, an allergy shot will help reduce your flaring immune system.

    According to the EPA, various types of mold can cause health problems for some people. Those health problems are primarily in the form of allergies such as stuffy head, headache, itchy eyes, trouble breathing, etc. These ailments can be more severe in the young, the old, and those with other health issues. The CDC basically says the same thing that mold can cause health issues in some people, or no issues in other people.

    According to the CDC, Stachybotrys black mold is unproven to cause serious medical issues beyond those mentioned above. In other words, symptoms of black mold are only proven to be similar to other molds. The CDC simply states that various types of mold may cause health symptoms, to consult with a doctor if symptoms persist, and that no color or type of mold belongs in a building.

    You may be thinking: If all we know for sure is that mold causes allergies in some people, and maybe some serious health problems in a small percentage of other people, then whats the big deal?

    How Does Mold Form On Bread

    Everything You Need to Know About Household Mold

    As molds, and fungi in general, are heterotrophs, they are required to consume nutrients in order to obtain the energy needed to function. In order to grow, mold requires nutrients, moisture, air, and an appropriate temperature. The carbohydrates from wheat found in bread are suitable nutrients on which mold can grow, and bread contains the required levels of moisture to support mold growth. If the bread is in an environment with a temperature of greater than 4 °C and has access to the open air, mold can grow.

    If they can make penicillin out of moldy bread, they can sure make something out of you. Muhammad Ali

    Mold grows on food items such as bread by first coming into contact with the bread as a spore. Mold spores are ubiquitous in the air and float until they come into contact with an object on which they can grow. Once the spore has landed, it colonizes the food item, such as bread, by germinating into a hypha, which spreads out into the bread like a net. The hypha exude digestive enzymes which catabolize nutrients for the mold to absorb.

    Is Black Mold The Worst

    Many people believe something called “black mold,” or “toxic black mold,” is a specific type of noxious mold that can severely sicken or even kill you because it releases noxious mycotoxins or mold poisons. But that’s not totally accurate. First, molds of all colors can cause illness. And second, there are many types of black-colored molds. The one most people have in mind when they refer to black mold, or toxic black mold, is Stachybotrys chartarum , a greenish-black mold.

    Research published in Analytical and Bioanalytical Chemistry suggests S. chartarum may be linked to serious health problems such as mycotoxicosis, or mold poisoning. Other possible ill effects include body aches, headaches, memory loss, mood swings and nosebleeds. But the science isn’t definitive. A 2017 report published in Clinical Reviews in Allergy & Immunology states, “There is no scientific evidence that exposure to visible black mold in apartments and buildings can lead to the vague and subjective symptoms of memory loss, inability to focus, fatigue, and headaches that were reported by people who erroneously believed that they were suffering from ‘mycotoxicosis.’ Similarly, a causal relationship between cases of infant pulmonary hemorrhage and exposure to ‘black mold’ has never been proven. Finally, there is no evidence of a link between autoimmune disease and mold exposure.”

    Toxic Mold: The Complete Picture

    The story about toxic mold whether black, white, or orange is more complex than most people know. First, although all mold growth is capable of producing mycotoxins , none produce mycotoxins all the time. Not even Stachybotrys.

    • Mycotoxins are produced only when two conditions occur at the same time: 1. When mold is eating and producing secondary metabolites and, 2. In the presence of competing bacteria or mold. If both conditions are not present then mycotoxins will not be produced.
    • Second, mycotoxins are not some mysterious substance with properties like radiation that can penetrate through walls. They dont stick to contents creating cross-contamination days or weeks later. They also cant be killed, because they arent alive.
    • Third, mycotoxins are not even the most prevalent component of mold that can cause reactions. Mold growth can also generate gas which are more common than the particles containing the mycotoxins, so the focus on mycotoxins is limiting.

    Types Of Mold Categorized By Health Effects

  • Allergenic molds affect people who have certain allergies or asthma. When people who are allergic to mold are exposed to it, they have a hypersensitive reaction, during which an excessive number of mast cells are activated, resulting in an extreme inflammatory response in the respiratory system. About 20%-30% of the population is susceptible to mold and/or other allergens, which can lead to reactions like allergic rhinitis. Most people without allergies are unaffected by allergenic molds in small amounts.
  • Pathogenic molds are capable of causing certain infections or diseases. Most healthy individuals, with their immune systems in good shape, are able to regularly fight off pathogens. However, pathogenic molds are dangerous to people who have compromised or weakened immune systems, which is why pathogenic molds are considered an opportunistic pathogen. Pathogenic molds most commonly affect infants, the elderly and people with suppressed immune systems.
  • Toxic molds produce mycotoxins, poisonous chemicals that are dangerous to humans. Unlike allergenic and pathogenic molds, toxic molds intentionally harm other living things rather than the harm merely being a side effect. Some of the most deadly chemicals on the planet are mycotoxins. Theyre found both on mold and on mold spores. People can get exposed to mycotoxins via ingestion, dermal exposure and inhalation. This can lead to temporary irritation or even long-term illness depending on the individual.
