Is “Black Mold” Equivalent to “Toxic Mold”? No, black mold is not equivalent to toxic mold. “Black Mold” is a term that is often used incorrectly to refer to toxic mold. In fact even the term “toxic mold” is also not entirely accurate. The correct term to use is “toxigenic mold”. Toxigenic molds refer to those molds that produce byproducts (i.e.,secondary metabolites) that are toxic to humans and animals. These toxic byproducts are referred to as mycotoxins. It is important to note that not every mold produces mycotoxins and toxigenic molds do not produce mycotoxins all the times. Several factors influence the production of mycotoxins by toxigenic molds. These include environmental conditions such as temperature, water activity, and humidity. Other factors such as pH, fungal strain, and substrate also play a role.

Black Mold
Aspergillus niger

While certain molds produce mycotoxins, the molds themselves are not toxic or poisonous. However, both toxin and non-toxin producers are may cause allergic reactions in sensitive individuals.

Are All Black Molds Toxigenic?

Not all black molds are toxic molds. The color and production of mycotoxins by molds are two different things. Black colored mold has a black pigment by nature which is not in any way associated with being a toxin producer.

The incorrect association of black color of mold with “toxicity” came about because of Stachybotrys chartarum, a dark black or sometimes dark green fungus. It can grow on material with a high cellulose content, such as fiberboard, gypsum board, and paper. Growth occurs when there is moisture from water damage, water leaks, condensation, water infiltration, or flooding. Constant moisture is required for its growth. In the 1990s, Stachybotrys chartarum was implicated in the death of children in Cleveland, Ohio. However, according to the Centers for Disease Control and Prevention (CDC), a possible association between acute idiopathic pulmonary hemorrhage (sudden unexpected bleeding of lungs) among infants and Stachybotrys chartarum has not been proven . Although there isn’t clear evidence linking sudden unexplained bleeding in infants to Stachybotrys chartarum (black mold), the fact that it’s black has caused the general public to think that all black molds are harmful.

Studies have shown that Stachybotrys produces and releases mycotoxins on cellulose-containing water damaged building materials. These mycotoxins can also be present in the spores that get released into the air and, while not scientifically proven, could cause danger to human health when inhaled.

Other Examples of Black Molds Commonly Found in Water-damaged Buildings.

Aspergillus niger: This mold is black and is commonly found in soil, decaying vegetation, and food. It is commonly present in indoor environments but is not typically associated with contaminated building materials. However, Aspergillus niger can also grow on damp building materials such as drywall and wallpaper as well as leather products. While it is an infrequent cause of aspergillosis, it can cause infections in the ears, nose, and lungs, particularly in individuals with compromised immune systems.

Chaetomium globosum: This mold appears black and is commonly found in water-damaged buildings. It grows on cellulose-rich materials such as drywall, wallpaper, and carpet. Chaetomium globosum may cause allergic reactions especially to immunocompromised individuals.

Cladosporium sp: This mold may appear black. It is very common in indoor environment. Cladosporium sphaerospermum for example is very common on wet building materials especially acrylic painted walls, wallpaper and insulation. Cladosporium species are well known causes of allergy.

Ulocladium sp: This mold is black and is commonly found in water-damaged buildings. It grows on cellulose-rich materials such as wood, paper, and cardboard. Little is know about the health effects of Ulocladium.

It’s crucial to emphasize that all molds pose a potential health risk, regardless of their ability to release mycotoxins. As a result, it is advisable to remove any mold growth in occupied indoor environments, regardless of the mold type. Additionally, identifying and addressing the cause of mold growth is essential.The post Is “Black Mold” Equivalent to “Toxic Mold”? appeared first on Mold Testing and Bacteria Testing.]]>

If you see black mold in your home, DO NOT panic! A number of molds can sometimes be found growing in houses on drywall, wood, behind wallpaper, and on ceiling tiles in areas that are constantly moist or have suffered water damage or leaks.

mushroom-like and black moldSome of these molds such as Stachybotrys, Aspergillus and Penicillium are associated with adverse health effects. Others like Alternaria and Cladosporium are well known allergens that trigger allergic reactions to sensitized individuals.

BUT, not all black molds that occur indoors are hazardous. Also, some dangerous molds are not black.

For $54.99 (Canadian dollar) per sample, you may submit a mold sample to determine whether the mold present is hazardous or only a cosmetic concern. A tape-lift mold sample is the most inexpensive test, and from it, Mold & Bacteria Consulting Laboratories can give you information and guidance on what to do next. It is an easy way to determine if the mold is toxic and if it will require more intensive investigation and remediation. Cleaning hazardous mold requires special protection.

How Do You Take Mold Samples?

If you hire a professional mold inspector to come to your home, they’ll take samples and send these samples to a third-party laboratory to find out the kinds of mold present in your home. What if you can collect the samples yourself and send them directly to the same lab? It would not only save you money but also give you an opportunity to discuss your mold test results with microbiologists who understand these molds more than anyone else.

Taking Mold Samples is easy! All you need is CLEAR SCOTCH tape and to follow the simple steps below.

  1. Wear gloves if necessary.
  2. Cut a few inches of clear scotch tape (2-3 inches). Avoid touching the sticky side.
  3. Holding the edges of the piece of tape, press it gently to the suspect area. Apply light pressure to the non-adhesive side.
  4. Peel tape off surface with slow, steady pressure, holding the tape edges only.
  5. Without folding the tape, apply sticky side of tape (i.e., side with mold) to the inside of the plastic bag.
  6. Close bag and label the outside of the bag with a brief description of the sample. For example:
    • Tape #1: Basement, east wall
    • Tape #2: Windowsill, master bedroom
    • Tape #3: Ceiling tile, bathroom
    • Tape #4: Under counter, kitchen sink.

    (NOTE: More than one mold type may be present. If several sites show visible mold growth, it is advisable to take more than one sample.)

  7. Put only one sample in each bag.
  8. Download, print and complete the sample submittal form. If you cannot print the form, get a blank sheet of paper and provide the following information:
    • Name
    • Address
    • Phone
    • Fax (if available)
    • Email address
    • The date the samples were collected
    • Credit card information for payment (Visa or MasterCard). You can also call us at 905-290-9101 to provide credit card information on the phone
  9. Put the samples into a mailing envelope together with your completed sample submittal form (or the sheet you completed) and mail your samples to:
    Mold & Bacteria Consulting Laboratories (MBL) Inc.
    1020 Brevik Place, Unit 1A
    Mississauga, ON L4W 4N7
    Canada.

We’ll analyze your mold sample in our ISO 17025 Accredited laboratory and send you a lab report to tell you:

  • exactly what type of mold your sample is
  • whether your sample is a toxic mold or just a cosmetic problem
  • if there are any known health problems associated with that mold and what they are
  • how to safely remove it
  • how to make sure it never comes back.

Is Mold a Concern? For Your Peace Of Mind, Have Samples From Your Home Tested For Black Mold

Is black mold affecting your family’s health? Mold growth in homes poses a significant health hazard, depending on the level of exposure and sensitivity of individuals. Possible negative health effects include increased asthma-related symptoms, such as chronic wheezing and irritation, and other respiratory conditions.

There’s been a lot of news about black mold and its effects on our health in the past few years. It is important to know that black mold isn’t the only toxic mold that can affect your family’s health. Here, we use the term “black mold” to mean any hazardous mold regardless of color.

Are you or a member of your family suffering from black mold allergy symptoms or other mold-related illnesses? Molds such as Stachybotrys, Aspergillus and Penicillium are associated with adverse health effects. Others like Alternaria and Cladosporium are well-known to trigger allergic reactions such as hay fever and even asthma.

Who is most at risk of black mold exposure?

Everyone is at risk. However, the elderly, young children, the sick, and those with a history of asthma are at higher risk of suffering from mold related illnesses. So if you find mold in your home, it’s important for everyone’s health that it is tested and then removed right away.
Mold Damage
 

If You Have Mold in Your Home, Don’t panic!

While all molds are potentially a health hazard, not all molds that occur indoors can affect your health, but even a small amount of mold growing in your home should be identified and removed. For $54.99 (Canadian dollar), you can have a mold test performed by an accredited laboratory in Canada.

How do you know if the mold is hazardous? Simply send samples to our lab for testing.

How to Collect and Send Samples to the Laboratory for Mold Testing

The black mold, Stachybotrys, is a well known producer of toxic byproducts (mycotoxins). The species most common in building environment are Stachybotrys chartarum and Stachybotrys chlorohalonata. These species have been linked with health problems associated with poor air quality in mold- contaminated buildings.

Stachybotrys black mold
Stachybotrys chartarum

In eastern Europe, in the 1930s, outbreaks of a disease of horses and other animals that was characterized by symptoms such as irritation of the mouth, throat, and nose; shock; dermal necrosis; a decrease in leukocytes; hemorrhage; nervous disorder; and death were associated with Stachybotrys chartarum (then known as S. alternans) present in straw and grain fed to the horses.

Currently, health effects in humans attributed to Stachybotrys chartarum, are controversial. However, it is generally agreed that Stachybotrys chartarum can potentially cause allergic reactions from inhaled spores and also poses the threat of mycotoxin poisoning.

One of the disputed claims is the association of Stachybotrys with the idiopathic pulmonary hemorrhage that resulted in deaths of infants in Cleveland, Ohio, USA, in 1993-1994. After a review of the reports, the US Centers for Disease Control and Prevention (CDC) concluded that a possible association between pulmonary hemorrhage in infants and exposure to molds, specifically Stachybotrys chartarum, was not proven.

Spores of Stachybotrys are believed to contain high concentrations of mycotoxins. Therefore, inhaling large numbers of these spores potentially can cause mycotoxin poisoning. Luckily, spores of Stachybotrys are not readily disseminated in the air, primarily because they usually occur in a cluster covered with wet slime. Therefore, exposure to huge amounts of airborne Stachybotrys spores would only occur when the spores dry out and are disturbed, for example, during renovations.

Black Mold (Stachybotrys) as a New Emerging Opportunistic Human Fungal Pathogen

Recently, Stachybotrys chlorohalonata, was isolated from the sinuses of a patient. This is the first reported case of invasive Stachybotrys chlorohalonata sinusitis. The patient was cured from this infection after sinus surgery and antifungal treatment.

S. chlorohalonata is very closely related to S. chartarum. It differs morphologically from S. chartarum by having smooth spores, and having more restricted growth on lab media.

A number of molds can sometimes be found growing in houses on drywall, wood, behind wallpaper, and on ceiling tiles in areas that are constantly moist or have suffered water damage or leaks. Some of these molds such as Stachybotrys, Aspergillus and Penicillium are associated with adverse health effects. Others like Alternaria and Cladosporium are well known allergens that trigger allergic reactions to sensitized individuals.

Not all molds that occur indoors are hazardous. However, current Canadian mold guidelines advise building occupants to clean-up and/or remove visible mold growth. To control mold growth, moisture should be eliminated or reduced.

For $50 per sample you can submit mold samples to Mold & Bacteria Consulting Laboratories to determine whether the mold present is hazardous or is only of cosmetic concern. Cleaning hazardous mold requires special protection. To collect a sample of visible mold, no special mold testing kit is required! Use clear scotch tape.

How to take Tape Samples for Mold Testing

Definition of Water Activity

Water activity (aw) refers to “free” water available for microbial growth. For microbial growth to occur, moisture must be freely available. The water activity of a material determines which types of mold would grow on that material.

Technically, the water activity is defined as the ratio of the vapour pressure exerted by the water in the material to the vapour pressure of pure water at the same temperature and pressure. Check out our Mold Inspection, Identification and Control course to learn more about Water Activity. 

Mold growth due to high water activity
Mold growth due to high water activity

Types of Mold based on Water Activity

Indoor molds vary in their water activity requirements and this ranges from 0.7 to >0.9. Higher aw materials tend to support the growth of more microorganisms. Unlike molds, bacteria usually require a water activity of at least 0.91 aw. Molds can be grouped according to their moisture requirements as follows:

  • Extremely to moderately xerophilic. These molds are the primary colonisers and they are capable of growth below 0.8 aw. Examples include Aspergillus and Penicillium
  • Slightly xerophilic. These molds are the secondary or intermediate colonisers. They are capable of growth between 0.8 and 0.9 aw. Examples of molds in this category include Altemaria and Cladosporium
  • Hydrophilic. Molds in this category are tertiary colonisers and require at least 0.9 aw for growth. Such high water activity can only be achieved through water intrusion and to a lesser extent high humidity and condensation. Examples of hydrophilic molds include Stachybotrys and Chaetomium

Check out our Mold Inspection, Identification and Control course to learn more about Types of Mold.

Note:

  1. Xerophilic means “dry loving.” Thus, xerophilic molds are those that can or prefer to grow in “dry” environments. “Dry” is used here in relative sense since no mold can grow in a completely dry environment.
  2. Hydrophilic means “water loving.” Thus, hydrophilic molds are those molds that require very high levels of moisture to grow.

Indicators of Water Damage

Water damage may occur over many months, mainly through roof leakage, but also via rising damp and defective plumbing, which result in mold growth. Indoor molds as well as bacteria are usually saprophytic, meaning that they obtain nutrients from dead organic matter. The nutrients are from the breakdown of simple to complex sugars such as starches, cellulose and pectin. The materials most susceptible to mold growth are organic materials containing cellulose (i.e. jute, wallpaper, cardboard and wooden materials). The tertiary colonisers are used as the indicators of moisture damage. The table below shows some of the most common indicators of water damage in buildings.

Indicators of excessive moisture or chronic condensation

Molds indicative of moisture or chronic condensation in a building

Aspergillus fumigatus is a thermotolerant/thermophilic fungus capable of growing over a wide temperature range (12°C–53°C). It has a worldwide distribution. Being thermotolerant, it is a significant component of compost microflora.

Health effects associated with Aspergillus fumigatus

The spores of Aspergillus fumigatus are very small. Having a diameter of 2–3.5 µm, they are easily inhaled deep into the lungs. It is estimated that people inhale at least several hundreds of spores of Aspergillus fumigatus per day without harm. However, Aspergillus fumigatus is an opportunist pathogen (Hazard Risk Group 2) and can cause a lung infection (aspergillosis), in people with weak immune system. Most of the cases of aspergillosis are caused by this fungus. Because of its potential role as an opportunist pathogen, there is concern about high concentrations of Aspergillus fumigatus spores in the vicinity of hospitals, where those with compromised immune system such as organ transplant and cancer patients, may be at increased risk of infection. Therefore, monitoring for airborne spores in hospitals especially during renovations is a good practice.

Aspergillus fumigatus
Aspergillus fumigatus

Occurrence of Aspergillus fumigatus

Aspergillus fumigatus naturally occurs in decaying organic material, but because it is a thermotolerant fungus it grows well at raised temperatures experienced during the composting process. Within the indoor environment, A. fumigatus belongs to the group of indicator microorganisms typical of moisture-damaged buildings such Stachybotrys, Chaetomium, Fusarium and Ulocladium. The following characteristics make A. fumigatus a ubiquitous opportunistic pathogen: 1) ability to survive and grow in a wide range of environmental conditions, 2) effective dispersal in the air, 3) physical characteristics that allow spores to reach deep into the respiratory system, and 4) ability to swiftly adapt to the host environment.

Air Sampling for Aspergillus fumigatus

In hospital environment, air sampling may be conducted to monitor air quality during construction, to verify filter efficiency, or to commission new space prior to occupancy. Because aspergillosis cases have occurred when airborne fungal spore concentrations ranged as low as 0.9–2.2 colony-forming units per cubic meter (CFU/m3) of air, it is suggested that an air volume of at least 1000 L (1 m3) should be considered when sampling highly filtered areas.

Sampling media and incubation temperature for Aspergillus fumigatus

Malt extract agar (MEA) can be used to sample for Aspergillus fumigatus. For selective isolation of A. fumigatus, a high incubation temperature of 37 to 40 is then used as this inhibits growth of other saprophytic fungi.

Poor indoor air quality can cause a number of health problems such as breathing difficulties and mold allergies. Like in any other city, indoor air quality testing in Mississauga is recommended to ensure the air we breath indoors is not causing sickness to our families as we spend about 90% of the time indoors. Humid or damp conditions in homes encourage mold growth. Signs of mold growth may include visible mold or musty smells from carpets, wood, and gypsum board. Mold spores and other microbial contaminants build up on floors, carpets, upholstery and other surfaces from where they are re-suspended into the air when disturbed thus contaminating the air. Mold spores such as those of Stachybotrys (black mold) contain allergens and toxic compounds. Health problems associated with inhaling mold spores include coughing, wheezing, and headaches. If you have a history of asthma, you are especially at risk as mold may trigger asthma attacks. Unfortunately you can never know the quality of the air you’re inhaling in your home until it is tested. If your family often experiences symptoms such as running nose, coughing, wheezing or other similar symptoms consider performing mold inspection and testing in your home.

Minimize Your Risk: Test The Air Quality In Your Home

To be sure, test the air quality in your home. While hiring an indoor air quality testing professional in Mississauga can be expensive, you can test the air in your home yourself using the same equipment that professionals use.

You need an air sampling pump and cassettes into which the pump draws the air. Since buying your own pump is expensive, you can rent the sampling pump and buy the cassettes from MBL. After you collect the air samples you ship or bring back the pump and the samples to the lab for testing. Once the lab analyzes the samples, we will send you the results that will help you decide whether you have a mold problem and whether you need to arrange for mold removal. The equipment comes with easy to understand instructions. Each air sample takes 5 or 10 minutes to collect. That’s to say, sampling will not take a lot of your time, yet you will save yourself hundreds of dollars. Yes, hundreds of dollars!

What Information Do I Get From The Lab?

The lab report includes a list of molds that are present in your house and their counts (per cubic meter of air) for each room that you tested. Upon request we can provide medical information (where available) associated with the molds in your home. The types of mold present indoors in comparison with outdoors sample will tell us whether the spores present in your house originated from outside or are from mold growing within your home. Air samples could give an indication of whether there is hidden mold growth or not.

How Much Does It Cost?

We can guarantee you it’ll cost you a third or less the cost of hiring a professional! The basic testing package for a single room is $182. The fee includes pump rental, lab analyzes and report. If you are testing more than one room, then each additional cassette (plus lab analyzes) will cost $66. The standard turnaround time for analysis of air samples is 3-5 business days.

How Do I Rent And Pay For The Package?

It’s easy! Give us a call at 905-290-9101 or 1-866-813-0648 (toll free) to arrange shipping or pick up the rental pump and the cassettes. If you want us to ship the equipment and the cassettes to you provide us with the shipping address and your credit card information on the phone.

kate-confused-600Why Mold Testing is Necessary

Homes and workplaces often have mold growth which requires mold testing to assess the risks to occupants. Mold testing helps to determine the types of mold present and whether they are a health hazard. Mold testing not only determines the species present but through more advanced mold testing methods a mold test can also quantify the concentrations of mold present in the air. Often mold testing is used to determine if there is a mold problem present in a building.
