Many types of molds, also known as fungi are some of the most toxic and deadly substances in existence.

There are over 400 known species of fungus (mold) that have been proven to be toxic to animals, humans and plants.These fungi (molds) release spores that produce toxic secondary metabolites that are called mycotoxins. Myco means fungal, and many molds are known to have toxic fungal metabolites that poison humans, animals and plants.

These molds can be found all over our environment and in our buildings. They make you sick, cause various illnesses and diseases. You can be exposed to a water damaged building with mold for a short period of time, and suffer a lifetime of illnesses.  According to the World Health Organisation more than 200 biotoxins have been identified from common molds and can interfere with RNA synthesis and may cause DNA damage.

The history, science and research has shown that it is one of the deadliest biological substances in existence for well over 50 years. They are so deadly, many countries around the world, including in the U.S., have used mold mycotoxins as chemical warfare agents.

So, do not let anyone fool you or tell you that mold is not dangerous!

mold mycotoxins

It has been proven through many studies that mold mycotoxins are highly toxic or carcinogenic. They cause inflammation and cancer, allergies, asthma and are potent immunosuppressive agents that directly affect immune cells and also modify immune responses as a consequence of tissue damage elsewhere. These diseases can also result in death if their are not treated properly.

According to one of the world’s premiere mold experts, Dr. Ritchie Shoemaker, Chronic Inflammatory Response Syndrome (CIRS), is the result of chronic inflammation produced by exposure to biotoxins (toxins produced from living organisms) that come from mold (mycotoxins). These biotoxins travel through the body distressing immunity, joints, the nervous system, and more. They change how you think, how you feel and even how long you live.

In the middle ages, people of western and central Europe died of the “holy fire,” or ergotism; in the 1940s many Russians died from alimentary toxic aleukia. These deaths were associated with eating food poisoned or contaminated with chemicals produced by molds (fungi). Interest in mycotoxins was stimulated in the United States and Europe about 1960 by the death of 100,000 turkey poults in England. These deaths and the deaths of other farm animals were associated with peanut meal that contained aflatoxins produced by the mold known as Aspergillus flavus and A. parasiticus.(1)

How mycotoxins enter the human body

Physical and biological environmental factors are important to the formation and accumulation of mycotoxins. Factors influencing the presence of the toxins in the environment, buildings and or foods include environmental conditions related to fungal strain specificity, instability of toxigenic properties, strain variation and fungal strain specificity.

Mycotoxins have several adverse effects on human beings, crops and animals that result in both economic losses and illnesses. Diseases caused by exposure to mycotoxins are known as mycotoxicoses. Acute mycotoxicoses can cause serious and sometimes
fatal diseases.

When you are around a toxin black mold, you are usually exposed to airborne mycotoxins by inhaling them. These mycotoxins then end up in the lungs and causing respiratory problems and other chronic symptoms. Trichothecene mycotoxins in the air can also enter your body through the eyes or be absorbed through the skin.

Another common way that mycotoxins get into the body is by eating contaminated food. This can happen if black mold has been growing on crops. Most mycotoxins including trichothecene remain active even after being cooked. This is the main reason why black molds are a major problem in agriculture. In 2004, over 120 people in Kenya died after consuming maize that was contaminated with aflatoxin. There are several other cases of animals dying after consuming pet food with mycotoxins as well.

These mycotoxins produce a disease called mycosis (plural: mycoses) which is a fungal infection of animals, including humans. Mycoses are common and a variety of environmental and physiological conditions can contribute to the development of fungal diseases. Inhalation of fungal spores or localized colonization of the skin may initiate persistent infections; therefore, mycoses often start in the lungs or on the skin. Fungal infections of the skin was the 4th most common disease in 2010 affecting 984 million people

A List of Molds and Their Mycotoxins

MIP - List of Mycotoxins

Some molds are capable of producing more than one mycotoxin and some mycotoxins are produced by more than one fungal species. While there are thousands of different mycotoxins, some of the most common ones include: ochratoxin, patulin, fumonisin, ochratoxin, aflatoxin (produced by aspergillus), zearalenoe and trichothecene which are all highly toxic or carcinogenic.

Trichothecenes

Stachybotrys produces various mycotoxins, and the most deadly myctoxin is called Trichothecene. Trichothecenes has been of great public health concern and has led to this fungus being known as “toxic black mold.” Other mold species that have this deadly toxin are Fusarium, Trichoderma, Verticimonosporium, Trichothecium, Cephalosporium and Myrothecium.

Trichothecenes are mycotoxins produced mostly by members of the Fusarium genus, although other genera (e.g. Trichoderma, Trichothecium, Myrothecium and Stachybotrys) are also known to produce these compounds. Trichothecenes are potent immunosuppressive agents that directly affect immune cells and also modify immune responses as a consequence of tissue damage elsewhere.

The trichothecene mycotoxins (TCT) (Fig. 4) comprise a vast group of over 100 fungal metabolites with the same basic structure. Several fungal genera are capable of producing TCT; however, most of them have been isolated from Fusarium spp. All trichothecene contain an epoxide at the C12,13 positions, which is responsible for their toxicological activity.

Trichothecenes including DON, T-2 toxin, and diacetoxyscirpenol are also important from the view of biological warfare.T-2 mycotoxins are also the only substances used in biological warfare that can be absorbed through a person’s skin.

At the cellular level, the main toxic effect of TCT mycotoxins appears to be a primary inhibition of protein synthesis. TCT affect actively dividing cells such as those lining the gastrointestinal tract, the skin, lymphoid and erythroid cells. The toxic action of TCT results in extensive necrosis of the oral mucosa and skin in contact with the toxin, acute effect on the digestive tract and decreased bone marrow and immune function (Schwarzer, 2009).(2)

Trichothecene can stay toxic for many years. It is probably the most lasting mycotoxins. Things like freezing temperatures or ultraviolet light do not have any effect on the mycotoxin. Trichothecenes resist sunlight, UV light, X-rays, heat (up to 120°C), and acids.

Aflatoxins

Aspergilus produces the major aflatoxins are called B1, B2, G1, and G2 (based on their fluorescence under UV light (blue or green) and relative chromatographic mobility during thin-layer chromatography) M1 and M2 (produced in milk and dairy products) (Fig. 1) (D’Mello and MacDonald, 1997).

Aflatoxin B1 is the most potent natural carcinogen known and is usually the major aflatoxin produced by toxigenic strains (Squire, 1981). Aflatoxins are difuranocoumarin derivatives produced by a polyketide pathway by many strains of A. flavus and A. parasiticus; in particular, A. flavus is a common contaminant in agriculture. Aspergillus bombycis, Aspergillus ochraceoroseus, Aspergillus nomius, and Aspergillus pseudotamari are also aflatoxin-producing species, but they are encountered less frequently ( Peterson et al., 2001).

Black mold symptoms and health effects

The American Academy of Allergy, Asthma & Immunology says that the most common allergy-causing molds include Alternaria, Aspergillus,Cladosporium and Penicillium. These molds can be found both indoors and outdoors. When these tiny mold spores become airborne, they can cause severe allergic reactions in people who have mold sensitivity issues, allergies and/or are immune compromised.

Prolonged exposure to the mold can cause severe and dangerous effects often compounded by allergic reactions to the mold spores. These symptoms include vomiting, nausea and bleeding in the nose and lungs. Mycotoxins may damage the lungs, brain, liver, kidney, heart, blood, or nervous system, produce facial eczema, and induce cancer or other effects.

Molds like stachybotrys chartarum and aspergillus or black mold normally release spores into the air as it feeds on organic substances like carpets, drywalls or damp sub-flooring. These spores if inhaled or ingested can result in a wide range of unpleasant and dangerous symptoms in human beings. The most common black mold health effects and symptoms include: sneezing, chronic coughing, irritation to the eyes, breathing problems, rashes, mucus membranes of the throat and nose plus persistent headaches.

Aspergillus produces aflatoxin which is associated with both toxicity and carcinogenicity in human and animal populations. The diseases caused by aflatoxin consumption are loosely called aflatoxicoses. Acute aflatoxicosis results in death; chronic aflatoxicosis results in cancer, immune suppression, and other “slow” pathological conditions. The liver is the primary target organ, with liver damage occurring when poultry, fish, rodents, and nonhuman primates are fed aflatoxin B1.(2)

Aspergillus causes a groups of diseases called Aspergillosis. The most common subtype among paranasal sinus infections associated with aspergillosis is A. fumigatus. The symptoms include fever, cough, chest pain, or breathlessness, which also occur in many other illnesses, so diagnosis can be difficult.

Mycotoxicoses, like all toxicological syndromes, can be categorized as acute or chronic. Acute toxicity generally has a rapid onset and an obvious toxic response, while chronic toxicity is characterized by low-dose exposure over a long time period, resulting in cancers and other generally irreversible effects (James, 2005).(2)

Fungus-infograph-MIP

Other symptoms of black mold include:

-Mental and neurological symptoms

-Circulatory symptoms

-Vision and eye problems

-Skin problems

-Immune system problems

-Reproductive system problems

-Tiredness and discomfort

Please keep in mind that these effects depend on things like health, immune system, age, diet, exposure level and gender of the affected person. The elderly, children and individuals with weaker immune systems will also be worse affected by the mycotoxin. The symptoms will also depend on how gradual or sudden the exposure was. Being exposed suddenly to a large amount of toxins might cause symptoms like pain and vomiting. Being exposed gradually over a long period might can cause long term symptoms like asthma, lung disease and or cancer.
