Fungal toxins can cause a range of adverse health effects. For instance, aflatoxins are potent carcinogens that can lead to liver cancer. Ochratoxins may cause kidney damage and have also been linked to cancer. Trichothecenes, such as deoxynivalenol (DON), can cause immunosuppression and gastrointestinal problems. Fumonisins are associated with esophageal cancer and neural tube defects.
