What Does USDA Actually Govern for Microgreens Growers?

USDA does not regulate the food safety of your microgreens. FDA does. USDA runs organic certification, a voluntary audit service, and grant money, and none of those three is a food safety rule.

This distinction is not academic. Growers lose weeks writing to the wrong agency, and some pay for an audit believing it satisfies a legal duty that it does not touch. The confusion has a real cause: a USDA auditor genuinely can turn up at a microgreens operation, clipboard in hand, and inspect how the crop is grown. That visit looks exactly like regulation. It is not. It is a voluntary commercial verification service, and USDA is explicit that product safety remains the responsibility of the producing and handling operation.

So this page draws the line. On one side, the things USDA actually runs and where to ask about them. On the other, the thing everybody assumes USDA runs and does not.

The division of labor, stated plainly

For a normal grower selling raw microgreens, the split is clean once you see it. FDA controls the federal food safety line: whether your crop is covered produce, whether your farm is eligible for an exemption, sanitation and worker health practices, agricultural water, biological soil amendments, animals, equipment, records, and any Produce Safety Rule inspection carried out by FDA or a state partner.

USDA controls three separate things that sit beside that, none of which is food safety law. Its National Organic Program controls whether you may make a regulated organic claim. Its Agricultural Marketing Service may conduct a voluntary GAP or GHP audit if you ask for one and pay for it. And several of its agencies run grants and cost share programs you may be eligible for. USDA describes these as parallel functions, not overlapping food safety jurisdiction.

Note what is missing from the USDA column. There is no USDA license to grow microgreens, no USDA food safety approval, and no USDA inspection you must pass before you sell.

Why the confusion is so persistent

Three things feed it, and each has a grain of truth in it.

The first is that USDA is the agency with "Agriculture" in its name, and microgreens are agriculture. That instinct is reasonable and wrong. The federal food safety statute for produce is FDA's. Section 419 directs FDA, not USDA, to set science based minimum standards for the safe production and harvesting of raw agricultural commodity fruits and vegetables, covering growing, harvesting, packing, and holding produce for human consumption. FDA laid this out in its record of decision for the Produce Safety Rule.

The second is that USDA's audit program genuinely covers microgreens. This is not a misreading. USDA's own GAP program scope document lists microgreens among the crops that may be audited. A grower who finds their exact crop named in a USDA document reasonably concludes USDA is their regulator. What that document actually establishes is that USDA will sell you an audit of a microgreens operation, which is a different proposition entirely.

The third is buyer language. A distributor writes "USDA GAP required" into a supplier specification, the grower reads "required," and the word does the rest of the work. The requirement is real. Its source is the contract, not the statute book.

USDA's first real job: the organic claim

If you sell microgreens as organic, USDA is your regulator for that claim, and only for that claim. The operative rule is 7 CFR 205.200: anyone intending to sell, label, or represent agricultural products as "100 percent organic," "organic," or "made with organic" must comply with the applicable production requirements.

The threshold that decides whether you need certification is in 7 CFR 205.101(a). An operation whose gross agricultural income from organic sales totals $5,000 or less annually is exempt from having to certify. Above that, certification is required before you may use the regulated organic claim, and USDA states the same thing in plainer language.

Two features of that $5,000 figure catch people out.

It is fixed. Unlike the FDA produce safety cutoff, which is a 2011 benchmark adjusted every year, the organic exemption ceiling is not inflation adjusted. It is the number in the regulation, and it stays the number in the regulation.

And it is narrow. It counts gross agricultural income from organic sales. Not total farm income, not net income, not all your sales. If you sell $40,000 of conventional microgreens and $4,000 of organic ones, the organic figure is the one the exemption looks at.

What certification costs, and what USDA pays back

There is no national price. An accredited certifier sets its own fee schedule, so USDA cannot publish one. What USDA does publish is a usable range: certification commonly runs a few hundred dollars for a small, simple operation and several thousand for a larger or more complex one. An invoice can bundle application, annual renewal, inspection, and sales assessment elements, so get a written quote from your chosen certifier before deciding whether staying under the $5,000 exemption is the better commercial call.

Once you are certified, money comes back. The Organic Certification Cost Share Program, run by USDA's Farm Service Agency, reimburses up to 75% of eligible certification costs, capped at $750 per certification scope. Crop certification is one scope. Eligible paid costs include application and administrative fees, inspection fees and inspector travel and per diem, certification fees, state organic fees, user fees and sales assessments, and related postage.

Two conditions matter. You must be certified, so the operation sitting under the $5,000 exemption cannot claim it. And you apply through a local USDA Service Center or a participating state agency, not through your organic certifier. As checked on 7 August 2026, FSA lists December 31, 2026 as the deadline for the 2025 and 2026 program years. That is a reimbursement deadline, not a certification application deadline, and the two get muddled constantly.

USDA's second real job: the voluntary audit

A GAP or GHP audit is not required by law for a microgreens farm. USDA describes the program in its own words as a "voluntary program" for the fruit and vegetable industry.

The consequence is worth stating twice, because it runs both directions. A farm can be legally obliged to comply with applicable FDA Produce Safety Rule requirements and hold no GAP certificate at all. And a farm can hold a GAP certificate and still owe every one of those FDA duties. The two systems do not net out against each other.

When a grower is told an audit is "required," the requirement is almost always coming from a wholesale customer: a distributor, retailer, food service buyer, processor, or organized market with a supplier specification. USDA publishes no national list of buyers and no mandatory buyer threshold. USDA does note that customers may specifically require a Harmonized GAP audit, which is not the same product as a basic audit.

That last point is where money gets wasted. Basic USDA GAP and GHP, Harmonized GAP, and the GFSI recognized Harmonized GAP Plus+ are not interchangeable merely because each contains the letters GAP. Get the exact specification from the buyer in writing before you book anything.

Cost works the same way as certification: there is no honest single price. USDA charges for the actual hours invested to review, approve, certify, and post results. The AMS rate schedule effective October 1, 2025 posts $171 for federal audit services and $171 for state audit services. Harmonized GAP Plus+ carries an additional $250 per audit GFSI certification fee on top of those service charges. Travel, audit scope, how ready your records are, and any corrective actions determine the final invoice, so get a quote from the assigned audit office rather than budgeting from a number you found online.

The process for a new applicant is published and short: set up an AMS billing account, choose the audit type, submit Request for Audit Service form SC-237A and Agreement for Participation form SC-651 to your local audit office, then schedule the audit. It is a documented review of your food safety practices against a checklist, followed by an on site audit of the growing, harvesting, packing and holding system.

What the audit does not do

USDA's position is alignment, not substitution, and USDA says so carefully. Basic GAP audits are aligned with industry best practices and FDA recommendations. Harmonized GAP aligns with FDA best practices and the FSMA Produce Safety Rule. Harmonized GAP Plus+ adds GFSI technical equivalency recognition.

Nowhere does USDA say an audit substitutes for an FDA regulatory inspection. It says the opposite in two ways: the audit does not guarantee freedom from microbial contamination, and product safety responsibility remains with the operation.

The legal reason is structural. The Produce Safety Rule arises independently from 21 U.S.C. 350h and 21 CFR part 112, and FDA maintains its own produce inspection program. An auditor's certificate neither waives the regulation nor limits FDA's inspection authority. What alignment genuinely buys you is less duplicate preparation, because the same practices and records serve both, plus the buyer relationship you wanted in the first place. Those are real benefits. Legal cover is not one of them.

If you want to know whether the Produce Safety Rule reaches your farm at all, that is a separate question with a separate answer, and it is worked through on the FDA Produce Safety Rule page.

USDA's third real job: money

This is the part of USDA most relevant to a small grower and the part least understood, mostly because the application routes go in different directions.

Read those eligibility notes before the dollar figures. Value-Added Producer Grants have a producer test you either pass or do not, and Regional Food System Partnerships require an eligible entity and an eligible partner to form the partnership. A grower who reads only the award band and starts writing a proposal is often already ineligible.

Timing is the thing that will actually stop you. As checked on 7 August 2026, most of these are closed. The Specialty Crop Block Grant federal application period is closed, and state proposal dates varied, with USDA's published state date list last updated May 11, 2026. Farmers Market Promotion closed June 5, 2026. Regional Food System Partnerships also closed June 5, 2026. The FY26 Value-Added Producer Grants notice required submission by 1:00 p.m. Eastern on April 22, 2026.

Food Safety Certification for Specialty Crops sits in an awkward spot. Its program page says the calendar year 2025 application period ran January 1, 2025 through January 31, 2026. No 2026 certification year window appears in the material checked here. Do not assume a new round exists. Ask your local FSA county office whether a successor notice has issued, and get the answer from them rather than from a blog.

The one currently open route is organic cost share, with that December 31, 2026 deadline for the 2025 and 2026 program years, for certified operations with eligible paid expenses.

One place the boundary genuinely moves

Everything above assumes you sell raw microgreens. The classification holds because a soil or substrate grown microgreen harvested above the growing medium is non sprout covered produce rather than a Subpart M sprout. FDA's sprout guidance draws that line: microgreens normally reach the true leaf stage, are typically grown in soil or substrate, and are harvested above the substrate.

Start turning fresh specialty crops into fresh cut product and the answer changes, and interestingly it is USDA's own document that says so. USDA's GAP scope document states that such processing falls under FDA's current good manufacturing practice regulation. At that point you should assess FDA facility and processing rules, plus any state or local licensing, as a separate exercise. Note the direction of travel: crossing into processing moves you further into FDA's world, not into USDA's.

Frequently Asked Questions

Q: I sell about $3,000 of organic microgreens a year. Do I need USDA organic certification? A: No. 7 CFR 205.101(a) exempts an operation with $5,000 or less of gross agricultural income from organic sales. You may sell and describe your own microgreens as organic. You still have to actually follow the organic production, handling and labeling rules, keep the records for three years, and you may not use the USDA organic seal.

Q: Is that $5,000 adjusted for inflation like the FDA figure? A: No, and this is the most common cross wiring on this topic. The FDA produce safety cutoff is a 2011 benchmark adjusted annually. The organic exemption ceiling is fixed. Two federal thresholds, two entirely different behaviors.

Q: My buyer says I need USDA GAP certification. Is that a legal requirement? A: Not a federal one. USDA calls the program voluntary. Your buyer's supplier agreement is a real requirement with real commercial consequences, but it is contractual. Ask them which standard and scope they accept, because basic GAP, Harmonized GAP and Harmonized GAP Plus+ are different products.

Q: If I pass a GAP audit, am I covered for FDA? A: No. USDA says its audits are aligned with FDA recommendations, and alignment is not substitution. The Produce Safety Rule duty exists independently and a certificate does not limit FDA's inspection authority. The preparation does overlap usefully, which is worth something, just not that.

Q: Which USDA office do I call about a grant? A: It depends on the program, and getting this wrong costs weeks. State department of agriculture for the Specialty Crop Block Grant. Local FSA county office for organic cost share and food safety certification reimbursement. AMS directly for Farmers Market Promotion and Regional Food System Partnerships. Rural Development for Value-Added Producer Grants.

Q: Does USDA inspect my grow room? A: Only if you ask it to and pay for it. A USDA auditor visits because you requested an audit service. Any inspection you did not request and cannot decline is a Produce Safety Rule inspection, which is FDA's rule, generally carried out by a state partner.

Final thoughts

The short version is that USDA sells you three things and regulates one claim. It sells certification services through accredited certifiers, it sells audits, and it hands out grant money. The only thing it truly governs for a microgreens grower is whether you may use the word organic. Everything about whether your crop is safe to sell, and what you must do to keep it that way, sits with FDA.

If you take one operational habit from this page, make it this: before you pay for anything with USDA's name on it, work out whether you are buying a legal requirement or a commercial one. Organic certification above $5,000 of organic sales is a legal requirement. A GAP audit almost never is. Knowing which is which is worth more than any single figure on this page.

Figures move. Audit rates are republished annually, grant windows open and close on their own schedule, and the food safety certification program has no published 2026 window in the material checked here. Verify a dollar amount or a deadline against the linked source before you rely on it, and ask your local FSA county office about anything that looks stale. If you find something here that does not match what a USDA office told you directly, tell me and I will check it.
