Food safety for microgreen growers: what buyers and inspectors ask for
The day you sell a tray, someone can ask how you know it’s safe. Usually it’s a chef or a store buyer, not an inspector. This page sorts out which rules apply to you, where contamination starts, and what to have written down. Then it points you to the right article for each step.
Start here: find your paperwork gaps
The Food Safety Gap Assessment walks your operation and shows which documents a buyer is likely to ask for that you don’t have written down yet. It costs nothing to find out where you stand.
Find my gapThe short answer
- Microgreens fall under the FDA Produce Safety Rule as regular produce. They are not sprouts, so the stricter sprout rules don’t apply. FDA
- How much of the rule applies depends on your sales. Many small farms are not covered or qualify for an exemption with lighter rules. FDA FAQ
- GAP certification is a voluntary USDA audit. No law requires it, but some buyers do. USDA AMS
- Seed is the main way germs get into a tray. Buying and handling seed carefully comes first. Xiao 2014
- An exemption doesn’t stop the questions. Buyers still ask what you do and where it’s written.
Do food safety rules apply to microgreens?
Yes. The FDA treats microgreens as covered produce. Your sales decide how much of the rule you have to follow.
The FDA says microgreens are not sprouts, since they grow in soil or another medium and are cut above it. That keeps them out of the sprout section of the Produce Safety Rule. The rest of the rule can still apply FDA.
Your farm lands in one of three groups FDA FAQ:
- Not covered. Produce sales averaged $25,000 a year or less over the last three years, adjusted for inflation.
- Qualified exempt. Total food sales averaged under $500,000 a year, adjusted for inflation, and more than half went straight to consumers or to qualified local buyers such as nearby restaurants and stores. You follow lighter rules.
- Covered. Everyone else follows the full rule.
The lighter rules are still rules. A qualified exempt farm has to keep records. It has to show the farm’s name and full business address on the label or at the point of sale 21 CFR 112.6.
Do you need GAP certification to sell microgreens?
Not by law. GAP is a voluntary audit, and buyers are the ones who ask for it.
USDA describes GAP audits as voluntary checks that produce is grown, packed, handled and stored in ways that lower the risk of germs USDA AMS. A farmers market may never ask. A grocery chain or distributor often does.
GAP and FSMA overlap, but passing one doesn’t mean you meet the other. Being GAP certified does not make you FSMA compliant lays out where they differ.
Where does contamination usually start?
With the seed. Germs on seed can grow along with the crop.
In a lab test, researchers grew microgreens and sprouts from the same radish seed, contaminated on purpose with E. coli. Both carried the germ. The microgreens carried far less than the sprouts Xiao 2014. Lower isn’t zero, so the seed you buy and how you store it matter.
For what the research says about eating microgreens, including how they compare with sprouts, see the food safety research hub.
What records should a small grower keep?
The ones that show what you did, when you did it, and who did it.
Under the Produce Safety Rule, a required record has to be made at the time of the task. It has to be dated and signed or initialed by the person who did it, and it has to be readable and permanent 21 CFR 112.161. A note written from memory a week later doesn’t meet that bar.
Buyers ask for the same kind of proof. A typical starter set covers seed lots, water, cleaning, worker hygiene, harvest dates and where each batch went.

What happens when something goes wrong?
A recall moves fast. The farms that come through it can say which lot went where.
The 2026 Canadian microgreens recall post-mortem walks through one recall step by step, and what a small grower can learn from it. For current US recalls, check the FDA recalls page.

Questions people ask
Are microgreens regulated like sprouts?
No. The FDA says microgreens grown in soil or another medium and cut above it are not sprouts. They skip the sprout-only section of the Produce Safety Rule, but the general produce sections can still apply.
Does the FDA enforcement pause passed in 2025 cover microgreens?
No. The pause came in the federal spending law for fiscal year 2026, passed in November 2025. It named four crops: wine grapes, hops, pulse crops and almonds. Microgreens growers kept the same duties they had before.
If my farm is exempt, do I still need records?
A qualified exempt farm still keeps records under the rule, and it has to put its name and full business address on labels or at the point of sale. A farm that isn’t covered at all has fewer duties, yet many buyers ask for records anyway.
How do I know if my sales are under the thresholds?
Average your sales over the past three years. The $25,000 produce limit and the $500,000 food limit both rise with inflation, so check the FDA’s current figures before you decide.
Where can I find a template for a food safety plan?
New Mexico State University’s All About Microgreens site posts one for microgreens farms. Penn State Extension and the Produce Safety Alliance publish grower guides too.
