Deoxynivalenol(DON)

Background
Deoxynivalenol (DON) is a mycotoxin produced predominantly by Fusarium fungi. It is one of the most prevalent and toxicologically significant trichothecenes found in food and animal feed. Due to its widespread occurrence in crops such as wheat, corn, oats, barley, and rice, DON is considered a major global food contaminant. Contamination can occur both in the field and during storage.

Associated Health Risks
Human exposure to DON can lead to acute gastrointestinal symptoms such as nausea, vomiting, diarrhea, abdominal pain, headaches, dizziness, and fever. Long-term or repeated exposure may result in more serious effects, including:

• Immune system suppression

• Cytotoxicity and oral epithelial damage

• Skin necrosis, hemorrhage, and anemia

• Granulocytopenia and toxic aleukia (ATA)

• Coagulation disorders and hypotension

The intestinal toxicity of DON is believed to be related to mitochondrial dysfunction triggered by reactive oxygen species (ROS), making oxidative stress a key contributor to its harmful effects.

Possible Sources of Exposure
DON may be found in a variety of foods, especially plant-based and grain-derived products such as:

• Bread, cereals, noodles, and malt

• Sorghum, buckwheat, and other grains

• Beer and other grain-based beverages

• Animal-derived foods like kidneys, liver, eggs, and dairy products (via contaminated feed)

Detoxification Strategies

• Activated charcoal (AC) may help reduce the body’s toxic burden by binding DON in the gut and supporting its excretion. To prevent nutrient loss, AC should be taken separately from meals, supplements, or medications.

• Milk thistle-derived silybins can support liver detoxification pathways.

• Antioxidant support from vitamins C and E may help reduce oxidative stress caused by DON exposure.
