Mycotoxins are toxic chemical compounds produced by certain fungi that can contaminate food, animal feed, and other organic materials. While mold itself is common in nature, only certain species produce mycotoxins, and not every mold exposure involves these compounds. Because of this distinction, it is important to understand what may actually be present rather than assuming all molds carry the same potential risks.

Research has shown that some mycotoxins may affect the liver, kidneys, immune system, and nervous system. Others have been associated with cancer, developmental concerns, reproductive effects, and other health impacts depending on the specific compound, the amount of exposure, and the duration of exposure. Different mycotoxins behave differently, making accurate identification an important part of understanding potential health risks.

Animals, including livestock and household pets, can also be affected by mycotoxins through contaminated feed or food. In some cases, exposure has been linked to digestive illness, organ damage, neurological symptoms, reproductive issues, and reduced productivity. Because mycotoxins cannot be identified by appearance alone, testing and proper evaluation are often necessary to determine whether they are present and whether corrective action is needed.
