Do You Need a License to Sell Microgreens in Missouri?

Missouri does not answer this question. Your county does, and it may answer differently from the county next door.

There is no statewide microgreens license and no statewide permit that covers growing and selling intact raw microgreens. But that is not the same as "no permit", and the distinction matters.

The Department of Health and Senior Services does not issue the permit. Your Local Public Health Agency, the LPHA for the county or city where you pack or sell, decides whether your activity is a retail food establishment, issues any permit, sets the fee, and enforces its own ordinance. Missouri says expressly that counties and cities may impose stricter rules, permits, fees and training than the state baseline.

So the honest answer is conditional. Grow and sell intact raw microgreens and no state license attaches automatically. Run a staffed farmers market booth, a grocery-style retail operation, or a facility that cuts, packs, holds or serves food, and your LPHA can require a permit and a pre-opening inspection.

Call them before you buy packaging or build a booth. DHSS Bureau of Environmental Health Services can route you if you cannot find them: 573-751-6095, RetailFood@health.mo.gov.

The federal layer applies on top. See the FDA Produce Safety Rule page.

Where the line falls, and who draws it

That last row is DHSS's own advice to mobile operators and it is the trap most likely to catch a grower doing three markets across two counties.

For produce farms covered by federal FSMA, a separate program applies: MDA's Produce Safety Program administers the FDA Produce Safety Rule inspection. That is not a retail license and does not substitute for one.

Cottage food, and a cap that no longer exists

Missouri's cottage food statute, RSMo 196.298, covers a home operation producing baked goods, canned jams and jellies, or dried herbs and herb mixes, sold directly to consumers. Fresh microgreens are a raw agricultural commodity and are not on that list.

There is a second thing worth knowing because it circulates constantly. The 2022 bill, HB 1697, effective 28 August 2022, struck the former $50,000 gross income condition rather than keeping it. So Missouri's cottage food route currently has no sales cap.

Both facts point the same way for you: it is not your route, and the number people quote about it is not a live number anyway. Do not use cottage food as the basis for selling raw greens, and do not assume it lets you use a household kitchen for microgreens. It does not.

The one number that does apply to you

Most states in this series have a licensing threshold. Missouri's meaningful number is a tax threshold, and it is easy to trip without noticing.

Fresh farm-grown products are generally taxable food at Missouri's reduced 1.225 percent state food rate plus applicable local tax. But under RSMo 144.527 there is a farmers market exemption for sales of farm products, and it ceases for a person or entity with estimated total annual farmers market sales of $25,000 or more.

So a grower building up a market round can cross from exempt to taxable purely by succeeding, with no regulator telling them. That is a fixed state figure, not an inflation-adjusted one, and it has nothing to do with FSMA despite sharing a number with the old federal baseline.

A 100 percent wholesale seller does not need to register for a retail sales tax license, and should keep Form 149 resale documentation where appropriate.

Food safety, inspections, and things Missouri gives away free

Inspections come from two directions. Local health agencies run routine inspections and everyday enforcement of retail food establishments, with frequency set locally and complaints able to trigger a visit. A new establishment needs an application and a pre-opening inspection through the LPHA.

MDA's FSMA inspections are different and unusually predictable: they are announced, they happen while at least one crop is being harvested, and they examine records as well as facilities. Not every exempt farm is inspected.

Free things worth using. MDA says its FSMA inspections and readiness reviews carry no cost to the grower. The On-Farm Readiness Review is free, confidential and voluntary, run with MU Extension, and is explicitly not an enforcement inspection. It is most useful after the farm survey and Produce Safety Alliance training rather than before.

Water testing is free too. MDA offers free water testing, and MU Extension reports free microbial water testing for Missouri growers in partnership with K-State. Given that water is where most produce safety programs cost growers money, this is the most valuable thing on this page for anyone running a covered farm.

Water standards. There is no longer a universal federal number of tests or a single numerical standard for pre-harvest water. Since the May 2024 revision, covered farms use a systems-based agricultural water assessment, in which testing may play a part but is not the sole measure of adequacy. For harvest and post-harvest water, use potable or safe water as the applicable rules require, and ask MDA whether you are covered before setting any testing frequency.

Training. No statewide food handler certificate is required. DHSS says cities and counties may require food handler or manager training, so ask the inspecting LPHA. A covered Produce Safety Rule farm needs a recognized Produce Safety Alliance grower training participant, which is FSMA training and not the restaurant-style food handler card.

Labeling

No Missouri-wide microgreens label rule was found. The defensible baseline for a packaged cut product:

Missouri prohibits misbranding under Chapter 196, so accuracy is enforceable even where the format is not prescribed. A plain single-ingredient raw produce package may have federal nutrition labeling exemptions; do not add unverified nutrient claims to fill space.

No statewide rule requires the exact phrase "Keep Refrigerated". A retail facility's cold-holding rules may govern, and a buyer may require the wording. Confirm any date, lot or producer information your LPHA wants locally, because that is exactly the kind of thing that varies by county here.

Business setup

A sole proprietor using only their own legal name needs no entity. Trading under a different name means a fictitious name registration under RSMo 417.200: $7, effective five years, which is among the cheapest in the country. An LLC is optional liability structure rather than a condition of selling greens; the posted fee is $50 online or $105 on paper.

Missouri has agricultural input exemptions rather than a blanket exemption from tax on sales. Farm machinery and equipment must be used for an agricultural purpose, on owned or leased land producing farm products, and directly in production for retail sale. Form 149 also identifies qualifying seed, fertiliser, herbicide, fencing and certain fuel and machinery provisions. Discuss a rack and light system with the Department of Revenue before claiming it: the published test is use and location, not whether you call yourself a farm.

Selling channel by channel

Farmers markets. Missouri publishes no universal farmer-vendor permit. Markets are retail settings inside the local regulatory landscape: managers may want a vendor application, insurance, a tax ID, product and label details, an attendance commitment and compliance documents, and the LPHA may add a booth permit, inspection or training. Watch the $25,000 tax threshold above. MU Extension runs a selling at the farmers market program that covers regulations and food safety, which underlines how local this all is.

Restaurants. Wholesale creates no Missouri license by itself, but it raises the documentation bar. The restaurant needs an approved supplier and will ask how the greens were grown, harvested, packed, refrigerated and traced. Keep Form 149 resale documentation where appropriate.

Grocery. Beyond the law, expect vendor onboarding, a certificate of product liability insurance, UPC or internal item data, package and lot traceability, delivery specifications and often GAP or a food safety audit. MDA's own position is that GAP is voluntary from a regulatory standpoint but may be a buyer requirement. It is market access, not a substitute for FSMA inspection.

Online. Within Missouri, keep the same truthful label, safe handling and local compliance. The cottage food in-state internet restriction does not apply to you, because microgreens are not cottage food. Shipping across a state line is interstate commerce: federal FSMA coverage, the destination state's rules, and carrier temperature protection. A farm doing only activities within FDA's farm definition need not register as a food facility; processing beyond that definition can change that.

Home growing, zoning and right to farm

There is no single Missouri home-growing zoning rule. City and county zoning, home occupation rules, leases and HOA terms, building and fire codes, signage, customer traffic and water and wastewater controls are all local. Get written confirmation from planning and zoning and the LPHA before using a residence as a packing or customer-pickup site. DHSS specifically notes that food processors may also need local zoning approval and business licenses.

A commercial kitchen is not automatically required to grow raw produce. It becomes a live question if local code demands it once processing or food service activity occurs, or if the LPHA classifies what you do as a retail food establishment.

Missouri has right-to-farm protections, but they are a defense against certain nuisance claims, not an exemption from food permits, zoning, sanitation or business licensing. Whether a small indoor or home operation counts as a protected agricultural operation is fact-specific. The MDA legal office is on 573-751-5633, and this is a question for a Missouri agricultural attorney rather than a website.

Insurance

General and product liability are advisable rather than a statewide prerequisite for selling food. One threshold is concrete: workers' compensation is required once an employer has five or more employees, except in construction where it is one or more. Sole proprietors and partners may elect coverage. That figure is fixed by statute.

Buyers require what buyers require: a certificate of insurance naming them as additional insured, product and general liability limits, indemnity, recall and cooperation terms, traceability and lot records, and compliance with their own supplier food safety program. None of it is set by Missouri statute.

What Missouri does not publish

The market

Missouri is sizeable but dispersed. The Census estimated 6,270,541 residents on 1 July 2025, up 1.9 percent from the 2020 base, and 2022 accommodation and food services sales were $18.523 billion.

Those numbers support targeted selling around the major metros and the college and medical centers rather than assuming even statewide demand. Competition is real but is not quantified in any official microgreens census, so map the farms, market vendors and chef accounts inside your actual delivery radius before you plant.

The product argument is the usual one and it holds here: specialty produce with a short shelf life rewards reliable weekly harvest and cold chain delivery far more than a price claim. The regulatory argument is specific to Missouri: because the rules are local, the county you pack in is a business decision, not just an address.

On funding, the MDA Specialty Agricultural Crops program serves Missouri resident family farmers below $100,000 in annual agricultural product sales, with eligible loans up to $35,000. MASBDA is on 573-751-2129.

Frequently Asked Questions

Q: Do I need a license to sell microgreens in Missouri? A: No statewide one attaches automatically to growing and selling intact raw microgreens. Whether you need a local permit depends on your county public health agency and what your operation actually does.

Q: Why can't you just tell me? A: Because Missouri deliberately does not decide it centrally. DHSS routes new establishments to the LPHA and says local jurisdictions may be stricter. Any page claiming a single Missouri answer is guessing on your behalf.

Q: Can I use the cottage food law? A: No. RSMo 196.298 lists baked goods, canned jams and jellies, and dried herbs. Raw produce is not there.

Q: What is Missouri's cottage food sales cap? A: There isn't one. HB 1697 struck the $50,000 figure in 2022. It is still widely quoted and it is not current, and it would not apply to microgreens even if it were.

Q: What is the $25,000 figure then? A: A tax threshold. The farmers market sales tax exemption ceases at estimated total annual market sales of $25,000 or more. Do not confuse it with the federal FSMA figure of $34,324.

Q: I sell at markets in two counties. One permit, or two? A: Assume two. DHSS tells mobile operators to check each local health department, and a permit does not travel with the booth.

Q: Is anything actually free here? A: Yes, and it is worth taking. MDA's FSMA inspections and readiness reviews cost the grower nothing, MDA offers free water testing, and MU Extension reports free microbial water testing with K-State.

Final thoughts

Missouri is the second most devolved state in this series after Texas, and the practical consequence is that your first phone call decides more than any statute does. The regulator you need is local, reachable, and allowed to be stricter than the state.

Three things to carry. Call the LPHA where you will pack, not just where you live, and get the classification before you spend money on packaging or a booth. Watch the $25,000 farmers market tax line, because it is the one number that moves as your business grows and nobody will warn you about it. And use the free water testing and the free readiness review, because Missouri gives away the two things that usually cost a covered farm real money.

If something here does not match what your local health agency told you, report it and it gets corrected. A page that is wrong about a rule is worse than no page.
