Understanding Mycotoxins: Sources, Formation, and Common Types

Types of Mycotoxins

What are Mycotoxins?

Mycotoxins are toxic substances produced by certain types of molds and fungi. They can be harmful to both humans and animals if we come into contact with them. It’s important to note that not all molds produce mycotoxins, and even those that do may not always produce them in every situation. The production of mycotoxins depends on factors such as the type of mold, the surface it’s growing on, and the environment it’s in.

The Main Sources of Mycotoxin Contamination in Indoor Spaces

Mycotoxin contamination can happen in different places inside buildings. Here are the most common sources:
  • Damp Surfaces: Molds like to grow in damp areas. So places with moisture problems like bathrooms, kitchens, basements, or areas with water leaks are usually where mycotoxin-producing molds are found.
  • Contaminated Food: Another common source is food that has mold on it. This includes stored grains, nuts, spices, coffee beans, and even some fruits.
  • HVAC Systems: If heating, ventilation, and air conditioning (HVAC) systems aren’t properly maintained or cleaned regularly, they can become breeding grounds for mold.
It’s important to know that mycotoxins can still be harmful even after the mold that produced them is gone. This means they can stay on surfaces or in materials for a long time after visible mold has been removed.

Common Types of Mycotoxins Found in Buildings

Out of the hundreds of known mycotoxins, only a few are commonly found indoors. Let’s take a look at these:
  • Aflatoxins: These mycotoxins are mainly produced by Aspergillus molds, especially A. flavus and A. parasiticus. They are very strong cancer-causing substances (carcinogens) and can also weaken the immune system.
  • Ochratoxins: Several Aspergillus and Penicillium molds produce these mycotoxins, which are often found in damp indoor environments. Ochratoxins have been linked to kidney damage and cancer.
  • Trichothecenes: ‘Black mold’ or Stachybotrys chartarum is the primary producer of this group of toxins. Trichothecenes can cause various health problems such as difficulty breathing, skin irritation, and a weakened immune system.
  • Zearalenone and Fumonisins: These mycotoxins are commonly found in grain-based foods that have been contaminated by different types of Fusarium molds. They are known to cause reproductive issues and liver damage.
This brief overview explains the basics of mycotoxins, where they come from indoors, and the common types found in such places. Understanding these toxic substances is crucial for creating a healthier living or working environment.

The Link Between Mycotoxin Exposure and Adverse Health Effects

Mycotoxins are toxic compounds produced by certain molds and fungi. They can be found in various environments, especially indoors, and pose potential health risks to humans. In this section, we will explore six specific types of mycotoxins and discuss their effects on health as well as the symptoms they can cause.

Aflatoxins

Aflatoxins are primarily produced by molds belonging to the Aspergillus species. They have been identified as powerful carcinogens and are often present in improperly stored food items. Prolonged or high-level exposure to aflatoxins can result in liver damage or even liver cancer.

Ochratoxin A

This toxin is mainly found in cereals, coffee beans, dried fruits, and red wine. Long-term exposure to ochratoxin A has been associated with kidney disease and negative effects on the nervous system.

Patulin

Patulin is mainly found in moldy fruits, particularly apples and apple products. Consumption of these contaminated foods can cause gastrointestinal discomfort and may lead to symptoms such as nausea, vomiting, and ulcers.

Trichothecenes

Trichothecenes are produced by molds like Stachybotrys, commonly known as black mold. Exposure to these toxins can trigger a severe immune response resulting in symptoms such as skin rash, burning sensations, sore throat, eye irritation, coughing, and wheezing.

Zearalenone

This mycotoxin primarily affects grains such as corn and wheat. It acts as an estrogen mimic in the body, which can disrupt normal hormonal balance and potentially lead to reproductive issues.

Fumonisins

Fumonisins are mostly found in corn and corn products. Studies have shown a link between fumonisin exposure and esophageal cancer, as well as neural tube defects in populations where corn is a staple food. The health risks associated with these mycotoxins highlight the importance of understanding how humans can come into contact with them. There are three main ways in which exposure can occur:
  • Inhalation: Breathing in mold spores or dust that is contaminated with mycotoxins is one of the most common routes of exposure. This is particularly prevalent in damp or water-damaged buildings where there is extensive mold growth.
  • Ingestion: Consuming food or drinks that are contaminated with mycotoxins can lead to ingestion of these harmful substances. Certain molds have the ability to produce toxins that contaminate crops, which then make their way into our food supply.
  • Dermal contact: Direct contact of the skin with mold or a surface that is contaminated with mycotoxins can also result in exposure. While not as common as inhalation or ingestion, this method still poses a risk, especially for individuals who have sensitive skin or pre-existing skin conditions.
Understanding the potential health effects associated with each type of mycotoxin and knowing the main ways in which exposure can happen are crucial initial steps in reducing the impact of these toxic compounds on human health. In the following sections, we will explore further how to recognize signs and symptoms of mycotoxin exposure, as well as provide practical tips on preventing and dealing with such exposures.
