Is Zeranol safe in food and drink?
Food processing1 use researched5 sourced claims
Where it turns up: growth hormone residue in meat. Detox My Life researched zeranol 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 (5)
ConsensusRestrictedconfidence 100%
Zeranol is banned for use as a growth promoter in livestock in the European Union, and the import of beef products from countries using it is prohibited, due to concerns about potential health risks and its classification as a hormone-like substance.
- Why here
- The European Union has taken regulatory action to prohibit zeranol in the food chain due to its classification as a hormone-like substance and potential health risks associated with ingestion.
- What would have to be true
- Ingestion of meat products from animals treated with zeranol.

ConsensusRestrictedconfidence 100%
Zeranol is approved for use as a growth promoter in livestock, including beef cattle and lambs, in the United States and Canada, with established tolerances for residues in edible tissues (e.g., 20 parts per billion in sheep) and is considered safe when used according to labeling.
- Why here
- The FDA has evaluated zeranol's safety for ingestion from treated animals and set regulatory limits for residues in edible tissues.
- What would have to be true
- Ingestion of meat products from animals treated with zeranol within regulatory limits.
Sources the engine cites:
EmergingSuspected carcinogenconfidence 100%
Studies suggest that dietary exposure to zeranol may increase breast cancer cell proliferation in existing breast cancer and can stimulate the growth of human breast tumor cells in vitro at potencies similar to estradiol.
- Why here
- Zeranol's estrogenic activity, when ingested, can promote the growth of estrogen-receptor-positive breast cancer cells.
- What would have to be true
- Dietary exposure to zeranol residues in meat products, even at low levels (e.g., 30 times lower than FDA approved limits in some studies).
Sources the engine cites:
EmergingEndocrineconfidence 100%
Ingestion of zeranol, a synthetic estrogen, is linked in studies to endocrine disruption in humans by mimicking natural estrogens and binding to estrogen receptors, potentially leading to hormonal imbalances and reproductive disorders.
- Why here
- Zeranol's structural similarity to natural estrogens allows it to interfere with the human endocrine system upon ingestion.
- What would have to be true
- Dietary exposure to zeranol residues in meat products or as a metabolite of zearalenone in contaminated food.
Sources the engine cites:
EmergingEndocrineconfidence 100%
Ingestion of zeranol and its related mycotoxin zearalenone has been associated with female reproductive changes such as precocious puberty in young girls and may contribute to abnormal mammary gland development.
- Why here
- Zeranol's estrogenic properties can interfere with normal reproductive development and hormonal balance when ingested during critical developmental stages.
- What would have to be true
- Dietary exposure to zeranol or zearalenone in contaminated food, particularly in young girls.

Not researched here
The engine has no dossier for zeranol 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.
