Is it safe to eat mycotoxin-contaminated peanuts and corn regularly?
No. Do not knowingly eat moldy or mycotoxin-contaminated peanuts, corn, grains, or spices.
What is actually in it
Mycotoxins are toxic compounds made by molds, including Aspergillus, Fusarium, and Penicillium. They can contaminate foods like peanuts, corn, grains, dried fruit, coffee, and spices.
This is not a scrape-it-off situation. Visible mold means the food should go. Cooking does not reliably make mycotoxin-contaminated food okay.
What the research says
A 2026 Journal of Biochemical and Molecular Toxicology review describes foodborne mycotoxins as molecular and epigenetic carcinogens.
The review explains that aflatoxin B1 is a well-established liver carcinogen. It also describes shared pathways for several mycotoxins: DNA adduct formation, oxidative stress, genomic instability, immune changes, and epigenetic disruption.
What to do instead
Buy nuts, grains, and spices from brands with strong quality control. Store them cool and dry. Use sealed glass, wood, or stainless storage when it fits the food. Throw away food with visible mold, stale smell, water damage, or clumping that was not there before.
