Is Fumonisin B1 safe in food and drink?
Food processing1 use researched2 sourced claims
Where it turns up: mycotoxin from mold on maize. Detox My Life researched fumonisin b1 under one use, because the same substance means something different in each use. Every claim below carries its evidence tier, how sure the research is that it applies here, and the sources it cites. The level is computed by the app's own deterministic engine, so the page says exactly what the app would.

Mainstream shows consensus claims only; Cautious adds emerging research; Based adds fringe claims, labelled as such. The last column counts, under Cautious, the sourced concerns, the findings in its favour and the fringe claims Based would add.
Safer swaps: the app's swap catalog has no entry tied to this ingredient yet. When you scan a product that contains it, the app suggests cleaner alternative types for that product; the swap categories list what the catalog covers today.

Sourced concerns (2)
ConsensusSuspected carcinogenconfidence 100%
Fumonisin B1 is classified by the International Agency for Research on Cancer (IARC) as possibly carcinogenic to humans (Group 2B) based on sufficient evidence in experimental animals, and epidemiological studies have associated chronic ingestion of fumonisin B1 with an increased risk of esophageal cancer in human populations.
- Why here
- Fumonisin B1 is a common mycotoxin contaminant of maize and other cereals, leading to human exposure through the ingestion of contaminated food products.
- What would have to be true
- Human exposure occurs through the ingestion of contaminated maize products, with regulatory guidance levels for total fumonisins in corn-based foods for human consumption, such as 150 ppb (0.15 mg/kg) for FB1 in the US.

ConsensusMetabolicconfidence 100%
Ingestion of fumonisin B1 can disrupt sphingolipid metabolism and has been linked to hepatotoxicity and nephrotoxicity in animals, and in humans, chronic exposure has been associated with liver and kidney disease, and neural tube defects.
- Why here
- Fumonisin B1 is a mycotoxin found in contaminated food products, primarily maize, which is ingested by humans.
- What would have to be true
- Tolerable daily intake (TDI) for fumonisins (FB1, FB2, FB3) has been established by the WHO/JECFA at 2 µg/kg body weight per day, and by EFSA at 1.0 µg/kg body weight per day.

Not researched here
The engine has no dossier for fumonisin b1 when cooked with heat, in cold food, as a finishing ingredient, in heated food packaging or other uses. The app researches an ingredient for the use it infers from your product, so a scan fills these in; this page only shows what has already been researched and source-verified.
This is research, not medical advice. Detox My Life shows sourced claims sorted by evidence tier. It does not diagnose, treat, or tell you to start or stop anything. Talk to a qualified professional about your health.
Scan your own. The app reads any product label with your camera, works out how you are about to use it, and researches every ingredient for that use with live sources. Every scan adds to a Detox Score for your home, where 50 is a typical home in your region, and a plan of next swaps.
