Wheat, corn, rice, oats, barley, rye, quinoa, buckwheat, sorghum, millet — milled or whole, the mycotoxin question comes first.
Grains are the classic mycotoxin substrate, and a common mistake is assuming FDA regulates them all the same way. It doesn't — the tool differs by toxin:
| Toxin | Mold / main grain | FDA level | Tool |
|---|---|---|---|
| Aflatoxin | Aspergillus — corn, others | 20 ppb total aflatoxins | Action level |
| Deoxynivalenol (DON / vomitoxin) | Fusarium — wheat | 1 ppm on finished wheat products | Advisory level |
| Fumonisins | Fusarium — corn | 2–4 ppm (by corn product) | Guidance levels |
"Enriched flour" must carry added thiamin, riboflavin, niacin, iron, and folic acid. You can't label a product "enriched" unless it meets those levels — and FDA also permits folic acid fortification of corn masa flour.
Declare wheat under FALCPA — in the ingredient list or a "Contains: Wheat" statement. Watch blended flours, seasoned mixes, and shared-equipment cross-contact. See allergen labeling.
A "gluten-free" claim must meet FDA's rule (101.91): less than 20 ppm gluten — including naturally gluten-free grains (oats, rice, corn) processed near wheat, barley, or rye.
"Whole grain" or "100% whole grain" must reflect the actual grain composition, and any related health claim must meet FDA's authorized health-claim rules. This connects to the bread standards on our bakery page.
| Requirement | Who | What it covers |
|---|---|---|
| Facility registration | Mill / processor / packer / warehouse | 21 CFR 1.225; DUNS/UFI; biennial renewal (even years, Oct–Dec) |
| U.S. Agent | Foreign facilities | Real U.S. address, reachable by FDA (no P.O. box) |
| FSVP | U.S. importer | Hazard analysis — mycotoxins, pathogens, pesticide residues, foreign material (Part 1, Subpart L) |
| Prior notice | Every import shipment | Filed before arrival; must match label, invoice, and entry |
| 60-day updates | Registered facilities | Report changes within 60 days (1.234) |
Mill/processor/packer/warehouse registers with a DUNS; foreign facilities add a U.S. Agent.
Control aflatoxin, DON, and fumonisins against FDA's action/advisory/guidance levels.
Label "enriched" only if it meets Part 137 fortification (folic acid); name products accurately.
Declare wheat; complete Nutrition Facts; substantiate gluten-free/whole-grain claims.
Prior notice + FSVP with grain-specific hazard analysis.
Renew every two years; report changes within 60 days; keep testing records.
FDA Registration Assistance registers mills and grain facilities, serves as U.S. Agent, builds FSVP programs with grain-specific hazard analysis (mycotoxins included), reviews labeling and enrichment, and coordinates prior notice — plus import-alert resolution if needed. Food Facility Registration is available as a service starting at $858.

Yes — any facility that mills, processes, packs, or holds them for U.S. consumption registers, including warehouses and grain elevators unless an exemption applies. Foreign facilities also need a U.S. Agent. Registration identifies the facility; it isn't approval.
Mycotoxins — toxins from molds that infect grains in the field or storage. FDA monitors imports closely, and there's a dedicated import alert (23-14) for detention without physical examination due to mycotoxins. Milling reduces levels but doesn't eliminate them.
With three different tools. Aflatoxin (Aspergillus, notably corn) has an action level of 20 ppb. DON/vomitoxin (Fusarium, wheat) has an advisory level of 1 ppm on finished wheat products. Fumonisins (Fusarium, corn) have guidance levels, commonly 2–4 ppm by product. Only aflatoxin uses an action level.
It reduces but doesn't remove them — which is why FDA's DON advisory applies to finished wheat products, not raw wheat headed to milling. Sourcing, cleaning, milling practices, and testing together keep products within FDA levels.
"Enriched flour" is a standard of identity (21 CFR Part 137) requiring added thiamin, riboflavin, niacin, iron, and folic acid. A product can't be labeled "enriched" unless it meets those levels. FDA also permits folic acid fortification of corn masa flour.
Yes — one of the nine major U.S. allergens under FALCPA, declared in the ingredient list or a "Contains: Wheat" statement. It matters especially for blended grain products, seasoned flour mixes, and shared-equipment products.
Yes — raw flour is a raw agricultural product linked to Salmonella and E. coli, so FDA advises against eating raw dough or batter. For products not cooked by the end user, a validated kill step such as heat-treated flour matters.
A "gluten-free" claim must meet FDA's rule (21 CFR 101.91) — under 20 ppm gluten. This applies to naturally gluten-free grains too (oats, rice, corn), especially when processed in shared facilities where cross-contact with wheat, barley, or rye can occur.
A "whole grain" or "100% whole grain" claim must reflect the actual grain composition, and any related health claim must meet FDA's authorized health-claim rules. A product that doesn't match the implied standard risks a misbranding issue.
No — USDA organic certification is separate. Facility registration, U.S. Agent, FSVP, prior notice, and FDA labeling all still apply to organic grain products; the two frameworks operate independently.
Yes — prior notice per shipment and an importer FSVP. For grains, the hazard analysis should address mycotoxins, pathogens, pesticide residues, heavy metals, and foreign material. The importer of record owns the FSVP.
Generally yes — a facility that holds flour or grain products for U.S. consumption, including warehouses, grain elevators, and storage, registers unless a specific exemption applies. Holding, not just manufacturing, can trigger registration.
No — registration tells FDA a facility exists and what it does; it isn't approval of the product. "FDA approved" based on registration is inaccurate.
