Types of mold and their level of toxicity

‘Toxic mold’ is a term used to describe mold forms that are deemed deadly to humans. Most people think the name refers to one specific mold species; however, it includes hundreds of species, a small fraction of which are not very harmful to the human body. For the most dangerous mold types, which tend to be black, black mold is widely used as a term. Also, molds of a different color can, however, be harmful to the human body.

A possible breeding pool for mold is any place that is dark and where there is an accumulation of moisture. As long as moisture and oxygen are present, mold can grow on nearly any organic surface. Mold growth can occur as large quantities of moisture build-up in buildings or construction materials. The removal of all indoor mold and mold spores is nearly impossible, although it is possible to handle it.

Each day, people are exposed to some amount of mold. Spores can be released into the air while a mold is forming on a surface, where a human can then inhale them. There may be some medical risk to a person who is vulnerable to inhaling a significant amount of these spores.

There are five toxic mold types. They are Cladosporium, Penicillium, Fusarium, Stachybotrys, and Aspergillus. Some of the species mentioned in these groups can only induce allergic reactions similar to hay fever, while others can cause potentially fatal diseases. Indoors, in damp rooms, all five of these mold families can be found lurking. Each has its own unique features that can have a significant effect on whatever organism or substance it touches. It is not always a clear indoor mold. On concealed surfaces, such as wallpaper, paneling, the top of ceiling tiles, and under the carpet, mold can manifest itself.

Stachybotrys Chartarum:

The toxin that Stachybotrys Chartarum produces is the most lethal. It has been related to illnesses as mild as hay fever, to illnesses as severe as liver damage, pulmonary edema, and to brain or nerve damage and even death in the most severe cases. It has also been related in infants to serious illness. When they come into contact with this species of mold, people with weakened immune systems, young children, and the elderly are particularly vulnerable to illness. Some of the related symptoms of Stachybotrys toxicity include:

  • Respiratory issues
  • Nasal and sinus congestion
  • Eye irritation
  • Sore throat
  • Hacking cough
  • Chronic fatigue
  • Central nervous system issues
  • Aches and pains

Cladosporium, Fusarium, and Penicillium

Diseases such as nail fungus, asthma, and even lung, liver, and kidney infections have been attributed to these mold families. Fusarium may also cause gastrointestinal diseases and even diseases that influence the female reproductive system. Pulmonary edema and emphysema can produce chronic cases of Cladosporium.


The Aspergillus mold family, the least extreme of the toxic mold classes, consists of over 160 species. In humans, only 16 of these cause disease, none of which is fatal if treated. Toxic molds create chemicals that are known as toxins or poisons during their natural development. The “toxic mold” mark is assigned to certain styles that have been shown to have profound effects on human health.

Toxic molds, if allowed to grow inside the house, are all very harmful. To prevent and eradicate their growth, proper precautions should be taken. The best way to stop the lurking of mold into your building is to caulking your house and it is especially important to caulk your quarters, kitchens, bathrooms, and laundries with quality materials to prevent mold and leaks as the humidity raised from these would be high.
