Do You Need a License to Sell Microgreens in Maine?

No, for ordinary fresh microgreens sold in essentially the same condition you harvested them in.

Maine's Department of Agriculture, Conservation and Forestry says farms, farm stands and farmers' markets need no license to sell fresh produce, including produce washed, cleaned, or sorted while it remains essentially unchanged. Normal harvesting, washing to get the soil off, trimming, sorting and display all sit outside the food-processing license. That is the statewide default, and there is no dollar figure attached to it. Sell $500 of greens or $50,000 of greens and the answer does not move.

Now the part of Maine law you have probably heard about, and the reason this page has two halves instead of one. Maine has a Food Sovereignty Act at 7 M.R.S. 282 to 286. A town, a plantation, or a county acting for unorganized territory can adopt a local food ordinance, and 7 M.R.S. 284 then tells the State not to enforce conflicting Title 7 and Title 22 food law for the transactions that ordinance governs. That is genuinely unusual. In Texas the local government adds rules the state declined to write. In Louisiana the state reaches down and forbids the parish from charging a farmer a fee. In Maine the town can reach up and switch off a piece of state enforcement.

Here is the honest conclusion, and it is not the exciting one. For raw microgreens, a local food sovereignty ordinance probably does not change your answer, because the state had already said no. The Act does real work for products the state actually licenses, such as home-produced foods and slaughtered meat. Your crop was never in that group. A grower in Sedgwick and a grower in a town that has never heard of the Act are, for licensing purposes, in the same position: no state produce license, because the produce exemption already covers them.

So do not go looking for an ordinance before you sell, and do not assume you need one. If your town has adopted one, read it, because it may add conditions of its own. If your town has not, which is most of Maine, you are on the state default and the state default is a yes to selling.

The answer flips to yes, you need a license when you change the product rather than where you sell it. Chopping, freezing, cooking, vacuum or modified-atmosphere packaging, or packaging the crop as "washed and ready to eat" moves you to a Food Processing and Manufacturing License from DACF's Quality Assurance and Regulations Division, on (207) 287-3200. Confirm the exact application classification and fee with DACF before you fit out a room.

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

Where the line falls

One desk decides the boundary. DACF's Bureau of Agriculture, Quality Assurance and Regulations Division licenses food processors and retail establishments predominantly selling prepackaged food, and it is the office that will tell you which side of the processing line your product sits on. Ask them in writing before you spend money on a room.

The Food Sovereignty Act, both halves of it

This is the section a Maine grower most often gets wrong, in one of two opposite directions. Some read the Act as a statewide license to do anything. Others read a neighboring town's ordinance and assume it is the law of the state. Neither is right, so take the two halves separately.

What an ordinance can do

7 M.R.S. 284 is the operative provision. Where a town, plantation, or county acting for unorganized territory has adopted a valid local food ordinance, the State will not enforce conflicting Title 7 and Title 22 food law for the transactions that ordinance governs. It is a withdrawal of state enforcement over a defined slice of activity, not a grant of new rights.

The slice is defined by 7 M.R.S. 282, and it is broader than most people expect. A direct producer-to-consumer transaction is written widely enough to reach roadside stands, farmers' markets, deliveries, buying clubs and CSAs. So raw produce is not carved out of the Act. Microgreens sold by the grower to the eater are the kind of transaction an ordinance can govern.

The catch is at the front end. The municipality has to actually adopt the ordinance. The Act does not exempt every grower in Maine automatically, and there is no statewide switch that has already been flipped. Confirmed examples of municipalities with local food sovereignty action include Blue Hill, Penobscot, Sedgwick and Brooksville, and there is no official statewide, exhaustive list of every town that has acted. Read the one that applies to your address, as enacted, rather than reasoning from a neighboring town.

What an ordinance cannot do

7 M.R.S. 286 is the limit, and it is the provision that keeps this page honest.

For every activity other than a governed direct producer-to-consumer transaction, 7 M.R.S. 286 requires compliance with all applicable state and federal food safety law. So the ordinance does not convert a case of clamshells delivered to a bistro into a direct consumer sale, and it cannot make an interstate shipment a local matter. A grower who builds a wholesale book on the strength of a town ordinance has misread the statute.

Your answer if your town has no ordinance

Most of Maine has no food sovereignty ordinance, and this is the position most readers of this page are in. You fall back on the state default, and the state default already says no license for ordinary fresh produce. The Act taking nothing away from you does not matter, because it was never going to give you anything you did not already have.

The same is true in an unorganized township. The Act lets a county adopt an ordinance covering unorganized territory, so check with your county, but the absence of one leaves you exactly where the state leaves everybody else: selling unlicensed fresh produce. Your genuinely different question in the unorganized territory is land use, which goes to the Land Use Planning Commission rather than to a town office. That is covered further down.

The 2025 amendment

The important recent change is already enacted rather than pending. Public Law 2025, chapter 309 amended the Food Sovereignty Act, including its definitions and its local-ordinance provisions. It did not make raw microgreens a cottage food and it did not change the fresh-produce result on this page. Read the enacted text rather than a summary if you are relying on a detail of the Act, and watch the enacted-law summaries for the 132nd Legislature. No pending Maine bill changing the microgreens fresh-produce exemption, or creating a cottage food cap, was verified as of 7 August 2026.

The Home Food License, and why it is the wrong door

Growers arrive at this page having read about a Maine Home Food License and assuming it is the cottage food route for their trays. It is not, and DACF says so directly: a Home Food License is not required for selling only fresh produce.

The license exists for shelf-stable, non-potentially-hazardous food made in a home kitchen. Microgreens sold as harvested are raw produce, which is a different regulatory object. Reaching for the Home Food License when you do not need it buys you an inspection and an annual fee for nothing.

For completeness, because the number circulates: DACF's current Home Food License guidance sets a $20 a year fixed license fee, product and sanitation conditions, and an initial inspection. It does not set a dollar sales cap. No statewide cottage food sales cap is published, so there is no cap figure and no last-change date to report. Ask DACF Quality Assurance and Regulations on (207) 287-3200 if you need that confirmed for a different product.

And note the trap in the other direction. DACF says a Home Food License does not solve a product that needs refrigeration or frozen control; those foods need a commercial food-processing license. So it is neither the route for your greens nor a shortcut past the processing boundary if you cross it.

Food safety, inspections and training

Maine publishes no microgreens-specific produce safety rule sitting above the federal one. The state layer is DACF's enforcement of the federal Produce Safety Rule through inspectors commissioned with FDA, plus Maine's general adulteration, misbranding and labeling law.

Microgreens are not sprouts. FDA describes them as usually harvested with true leaves, above the soil or substrate, which makes them covered produce under the ordinary provisions of the rule rather than the sprout-specific requirements of Subpart M, unless they are otherwise excluded or exempt. That distinction is worth knowing before someone at a market tells you otherwise.

The federal coverage figures, taken from FDA rather than from any state page. The current three-year values for 2023 to 2025 are $34,324 for the not-covered farm test and $686,476 for the qualified exemption, from FDA's column headed "Average 3 Year Value for 2023 - 2025". FDA prints single-year 2025 values of $35,247 and $704,950 beside them, and those are a different measure. FDA updates the cut-offs each April. Neither figure is a Maine license threshold, and Maine does not have one.

Inspections. An ordinary unlicensed fresh-produce operation has no routine DACF food-license inspection schedule, because there is no license to inspect against. A farm covered by the Produce Safety Rule can be inspected by DACF's FDA-commissioned inspectors. DACF says initial inspections are educational and currently scheduled in advance: they confirm coverage, walk through your activities, review records and issue FDA forms 482 and 4056. There is no published every-so-many-years frequency. A complaint, an adulteration concern, an FDA action, an outbreak or recall, or a significant observation can trigger a for-cause or follow-up visit.

Training. For a covered farm, at least one supervisor or responsible party must complete Produce Safety Alliance Grower Training or an equivalent course, and DACF says UMaine Extension offers it. No Maine food handler card requirement is published for a grower who only produces unchanged fresh microgreens. Do not substitute a restaurant food handler certificate for grower training; they are not interchangeable.

The free review. DACF runs the Produce Safety Rule implementation program under an FDA cooperative agreement and offers a free, non-regulatory On-Farm Readiness Review to a produce farm of any size, plus one-to-one assistance. The contact is Lindsay Werner, Inspection Process Analyst Coordinator, on (207) 592-2687 or Lindsay.Werner@maine.gov. Take it. It is preparation, not an approval, and it costs nothing.

Water

Below the coverage floor, no Maine microgreens water-testing frequency was found.

For a covered non-sprout farm, the federal rule now requires a written pre-harvest agricultural water assessment, done annually and again after a significant change. That replaced the old one-size microbial testing schedule. Test where your own assessment says to test, and stop using water immediately if it is not safe or adequately sanitary. Harvest and post-harvest water keeps its separate requirements: untreated surface water is prohibited for those uses, and untreated groundwater testing can apply.

The compliance dates are federal, not Maine license dates. The small-farm pre-harvest date was 6 April 2026 and the very-small-farm date is 5 April 2027.

Labeling

For a package of single-ingredient, Maine-grown microgreens, the elements are:

Two Maine-specific notes. The country-of-origin rule at 7 M.R.S. 530 applies to foreign-grown fresh produce, so it does not require a country statement on Maine-grown microgreens. And a farm operating under the federal qualified exemption must additionally label packaged produce with the farm's name and address.

On "keep refrigerated": no Maine statute or DACF microgreens rule was verified requiring that statement on ordinary raw packaged microgreens. Not published. Ask DACF Quality Assurance and Regulations on (207) 287-3200 with your exact product and package. Separately, do not claim "washed and ready to eat" unless the product was packaged in a licensed commercial facility, because that claim is one of the specific things that moves you across the processing line. The handling reality does not change either way: cut and bagged produce needs a cold chain you actually control.

Tax

Fresh microgreens are ordinarily exempt. Maine Revenue Services identifies vegetables as grocery staples, food ordinarily consumed for human nourishment, and exempts them from sales tax. A seller of only exempt fresh microgreens does not need a sales tax account merely to collect tax on those sales.

Two documents get confused with permits, so be clear about what they are. A Retailer Certificate is a sales tax registration, not a general food permit. A Resale Certificate lets you buy tax-free for resale and requires an active account plus $3,000 or more in annual gross sales, a fixed statutory threshold. If you also sell taxable goods or prepared food, register and account for those sales separately.

On inputs, the sales and use tax agricultural exemption at 36 M.R.S. 1760 covers seed, fertilizer, defoliants and pesticides used in commercial agricultural production. Equipment used directly and primarily in commercial agricultural production may qualify under the separate refund regime at 36 M.R.S. 1760-D. Both are fixed in statute and not inflation adjusted. Neither is a general shopping exemption: get a written determination from MRS before you treat racks, lights or packaging as exempt, because the statute does not make every indoor-farm supply exempt.

Business setup

You can operate as a sole proprietor without forming a state entity. If you use any name other than your own, Maine requires a sole proprietor to file a certificate with the municipal clerk where the business operates. The fee is set locally, so there is no statewide amount to quote.

An LLC is optional liability planning, not a food-selling prerequisite. The Secretary of State lists a domestic LLC certificate of formation fee of $175 and a domestic annual report fee of $85.

Selling channel by channel

Farmers' markets. No state food license for unchanged fresh microgreens. Maine defines a market as a place used by at least two farmers for direct sale, and 7 M.R.S. 415 requires a seller at a market called a "farmers' market" to have grown or processed at least 75 percent of the products offered. Anything bought in must come directly from another farmer, with that farm's name and location on the product or on an adjacent sign. The market itself can be stricter: application approval, fees, insurance, approved scales, attendance rules, vendor-origin documentation, cold handling. Read the market's own rules; they bite more often than the statute does.

Restaurants. Selling unchanged fresh microgreens wholesale creates no Maine produce license. It does mean the local ordinance route is generally unavailable to you, because 7 M.R.S. 286 requires full state and federal compliance for anything other than a governed direct producer-to-consumer transaction. What the chef will want is a traceable supplier, reliable delivery, product in suitable condition and a compliant label wherever product is packaged. If you want to sell chopped, MAP or vacuum packed, or "washed and ready to eat" product, move to the licensed facility path first.

Grocery. The legal baseline is the same exemption plus accurate labeling. A grocery's own retail food license does not license its suppliers. The buyer's contract is where the real requirements live: vendor application, lot and harvest traceability, delivery and cold chain specifications, a certificate of insurance, often a third-party food safety audit. Not published, because these are private terms. Ask the buyer's produce or procurement office for its supplier packet.

Online. Maine treats internet sales under the same sales tax analysis as mail order. Direct shipment out of Maine is not Maine sales taxed, while a seller required to register must collect Maine tax on taxable items shipped to a Maine address. Fresh microgreens are generally exempt anyway, so this matters mainly if you also sell taxable products. Across a state line, comply with the destination state's produce, labeling, tax and shipping rules. A Maine municipal food sovereignty ordinance cannot displace federal law or another state's law, so never present one as an interstate or wholesale exemption. Keep your shipping records.

Home growing and zoning

Maine has no statewide home-microgreens zoning permit, and this is where the local layer genuinely does bite.

Zoning, home occupation, accessory structure, signage, parking, water and sewer, and customer-visit rules are municipal questions. In the unorganized territory they are Land Use Planning Commission questions instead. Check the code and speak to the planning or code office before you install racks, put up a greenhouse, open a farm stand or invite pickup traffic to a residence. Note that this is a completely separate track from the Food Sovereignty Act: a town that has adopted a food ordinance has not thereby zoned your property for a farm stand.

A commercial kitchen is not triggered by growing whole, uncut fresh microgreens. The trigger is a change in condition or risk: chopping, freezing, cooking, vacuum or modified-atmosphere packaging, or packaging product as "washed and ready to eat". That product needs the food-processing and licensed commercial facility path, and a Home Food License does not substitute where refrigeration or frozen control is necessary.

Right to farm applies, with limits. The Maine Agriculture Protection Act says a compliant farm or farm operation is not a public or private nuisance where it follows best management practices and either meets the nutrient-management alternative or predates a neighboring land-use or occupancy change within one mile. It also prevents a qualifying farm operation, in an area where agriculture is permitted, from being deemed a municipal ordinance violation. Read the conditions in that last sentence carefully: it protects you in an area where agricultural activities are permitted. It is a defense and a limitation, not a license, and it does not pre-clear a home occupation in a district that prohibits one.

Insurance

For a one-person grower, Maine does not require business property or product liability insurance. The Bureau of Insurance says so expressly, while noting that product liability cover is prudent. It is: a foodborne illness claim, a delivery accident or a recall can exceed a small grower's resources outright.

Workers' compensation is required for almost all employers, subject to specific agricultural, casual and seasonal alternatives. A sole proprietor with no employees is not required to cover themself.

Auto insurance is required on vehicles used in Maine, and a personal policy may exclude business deliveries. Check the exclusion before you run a chef route in your own car, not after.

Advisable cover is product and completed operations liability, general liability, product recall and contamination where available, property and equipment, and commercial or delivery auto. Restaurants and grocers can contract for more even though Maine imposes no generic requirement: expect a certificate naming the buyer, buyer-set limits, indemnity and recall language, delivery temperature and condition standards, lot or harvest-date traceability, and right-to-audit terms. Not published, because these are buyer contracts rather than a uniform Maine rule. Ask each buyer's procurement office.

What Maine does not publish

The market

Maine is a thin, dispersed market. The Census estimate was 1,414,874 residents on 1 July 2025, up 3.8 percent from the 2020 estimate base. That population is spread across a very large state, which means a statewide delivery route is a bad first plan. Build density before you build mileage.

The practical targets are compact service areas: Greater Portland, Bangor, and a handful of others. Everything outside them is a long drive for a small drop.

Competition exists and is already differentiated. The Green Way advertises subscription, direct-to-consumer and restaurant wholesale microgreens in Greater Portland. Verdant Harvest in the Bangor area advertises restaurant and caterer supply with a stated capacity of 220 to 250 trays a week. Tripping Gnome Farm in Freeport sells microgreens alongside mushrooms and other produce. A generic "local microgreens" pitch is not going to move any of them. A tighter offer will: fixed chef delivery days, a short list of consistently available varieties, live-tray service, or a neighbourhood subscription.

The strategic read is specific to how Maine's rules are shaped. Nothing in Maine costs you money for getting bigger. There is no threshold to stay under, no annual produce license, and no fee that scales with sales. The only expensive line in this state is the processing boundary, and you cross it by changing the product, not by growing. So the sequence that makes sense here is to push volume and channels as far as they will go while the crop stays essentially unchanged, and to treat any move into "washed and ready to eat", MAP or vacuum packed product as a deliberate capital decision with a license, a facility and DACF's classification attached to it. Decide that on purpose, with a customer already asking for it, rather than drifting into it because a clamshell seemed tidier.

One more thing about the Food Sovereignty Act: it is a better marketing story than a licensing advantage. If your town has an ordinance, that is a real local-food conversation to have with your customers. It is not a reason to skip the state analysis, and it will not impress a restaurant buyer, whose purchase sits outside it anyway.

On support, DACF's Maine Healthy Soils Program offers no-cost testing and consultations plus 2026 grants; eligibility includes a Maine farm operation with at least $2,000 in gross annual value intended for commercial sale in one of the last three years, and access to one acre. The Working Farmland Access and Protection Program is accepting letters of inquiry, but it funds farmland-protection projects through eligible sponsors rather than operating cash for a microgreens start-up. UMaine Cooperative Extension's food safety program is on (207) 581-3188 or extension@maine.edu.

Frequently Asked Questions

Q: Do I need a license to sell microgreens in Maine? A: No, for ordinary fresh microgreens sold essentially unchanged. DACF says farms, farm stands and farmers' markets need no license to sell fresh produce, including produce washed, cleaned or sorted while it stays essentially unchanged.

Q: My town has a food sovereignty ordinance. Does that change anything for me? A: Probably not. 7 M.R.S. 284 withdraws state enforcement for the transactions a valid ordinance governs, but raw produce was already unlicensed statewide, so there was nothing for the ordinance to remove. Read yours anyway, since it may add conditions.

Q: My town has no ordinance. Am I worse off? A: No. You are on the state default, and the state default is the same answer: no license for ordinary fresh produce. Most of Maine is in this position, including unorganized townships whose county has not adopted anything.

Q: Can I use an ordinance to sell to a restaurant? A: No. 7 M.R.S. 286 requires all applicable state and federal food safety law for anything other than a governed direct producer-to-consumer transaction. Wholesale sits outside every ordinance, and so does an interstate shipment.

Q: Is there a sales figure that ends my exemption? A: No. Maine's fresh-produce result turns on the product and the activity, not on dollars. The $34,324 you may have read is FDA's three-year 2023 to 2025 coverage figure for the federal Produce Safety Rule, not a Maine license threshold.

Q: What actually makes me need a license? A: Changing the product. Chopping, freezing, cooking, vacuum or modified-atmosphere packaging, or packaging it as "washed and ready to eat" moves you to a Food Processing and Manufacturing License. Call DACF QAR on (207) 287-3200 before fitting out a facility.

Q: Do I need the Home Food License? A: No. DACF says a Home Food License is not required for selling only fresh produce. It is built for shelf-stable home-kitchen food, and it will not cover a product that needs refrigeration either.

Q: Do I charge sales tax? A: Generally no. Maine Revenue Services treats vegetables as exempt grocery staples, and you do not need a sales tax account merely to sell exempt fresh microgreens. Register separately if you also sell taxable goods or prepared food.

Final thoughts

Maine gives you two answers and you need both of them in your head at once. The state answer is that ordinary fresh microgreens are unlicensed produce, at any sales volume, in every town. The local answer is that a municipality can switch off state food-law enforcement for the direct sales it governs, which is a genuinely unusual power and, for your crop specifically, mostly beside the point.

Three things to carry. Do not go hunting for a food sovereignty ordinance before you sell, because you almost certainly do not need one and its absence takes nothing from you. Keep the direct and the wholesale halves of your business mentally separate, since 7 M.R.S. 286 puts wholesale outside every ordinance no matter where you live. And treat the processing line, not the town line, as the thing that decides whether you ever pay for a license in this state: a cut tray of greens is produce, and a bag that says "washed and ready to eat" is a facility.

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