Do You Need a License to Sell Microgreens in Wisconsin?

No, while they stay raw and intact.

Wisconsin does not answer this with a threshold or a building test. It answers it with a product category. DATCP's Wisconsin Local Food Marketing Guide lists raw intact fruits and vegetables (excludes sprouts) as needing no license when the producer sells them, and it sets that out channel by channel.

What makes Wisconsin distinctive is how far that category travels. In most states the produce exemption is a stall exemption: it covers the farm stand and quietly dies at the wholesale door. Wisconsin's guide names the farm, door-to-door and farmers market sales, then names the grocery store, the restaurant and the institution in the same table. The buyer does not end it. Only the product does. That puts Wisconsin in the same family as Minnesota, where the exclusion also follows the product, and apart from Indiana and Oregon, where selling to a restaurant ends the protection.

The other side of the line is just as clear. DATCP's license fee schedule treats cutting, packing and packaging as food processing. Harvest into a clamshell and call it ready to eat, and you are into the commercial framework: a Food Retail License under Wis. Stat. 97.30 and ATCP 75 for retail activity, or a Food Processing Plant License under Wis. Stat. 97.29 and ATCP 70 for wholesale processing.

DATCP expects you to describe the operation rather than self-classify. Food Licensing Consultants are on 608-224-4923, new licensees on 608-224-4720, and Safe Wisconsin Produce, the produce farm side, on 608-224-4511.

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

Where the line falls

The third row is the one that matters. A grower who reads only the farm stand line will underestimate what Wisconsin allows. If your greens are still raw and intact when the chef takes delivery, DATCP's guide says the producer needs no license for that sale. Plan around that.

The three words, and where each one bites

Raw rules out cooked, frozen and preserved. DATCP's guide puts cut, frozen or otherwise processed fruit and vegetables in a different row with a different answer, so a blanched or frozen product is not a variation on the exemption, it is outside it.

Intact is where microgreens growers actually live. A tray sold with the crop still growing in it is plainly intact. Harvested stems in a clamshell are the argument. A fresh intact crop can remain a raw agricultural commodity even in ordinary containers, but ready-to-eat cut, washed or leaf-stripped greens must be assessed with DATCP before sale. Do not assume washing, stripping or labeling something ready to eat is a neutral step.

Excludes sprouts sits inside the category rather than in a separate rule, so there is no version of this exemption that reaches sprouts. If any part of your operation is sprouts, that part is on the commercial track from the start. Be able to describe your crop's growth stage and harvest method clearly enough that nobody has to guess.

There is no verified special "live tray" license in Wisconsin and no separate live-tray rule. Present a tray for what it is, an uncut plant product, and get the classification from DATCP.

Once you cut: which license, and what it costs

Two categories, named on DATCP's own license page.

On cost, DATCP's fee schedule lists a Food Processing Plant under $25,000 in annual production at $95 annually, with potentially hazardous status moving the operation into higher bands. Do not read $25,000 as an exemption threshold; it is a fee band. Nothing in Wisconsin's produce rule turns on a dollar figure at all.

For a raw intact grower, neither license is the ordinary starting permit, which is worth saying plainly: a grower who calls DATCP and describes a business rather than a product can be walked into an application they do not need yet. DATCP's guidance for food entrepreneurs says licensing staff use your description of the product, where it is made, and how it is packaged and sold to identify the applicable rules. Describe the harvest, wash, bag, refrigeration and sales model precisely, and ask them to classify it.

Dane and Milwaukee are not on the state list

DATCP's licensed-facilities notice says its lists do not include facilities licensed by Dane or Milwaukee counties, and directs operators to those public health departments instead.

The practical effect: if you process and sell in Madison or Milwaukee, your licensing and inspection relationship may sit with the county agent rather than the state office everyone else calls. That changes who answers your questions, who inspects you and whose forms you fill in. It does not change the raw intact category, which is state law and follows the product wherever you are. Outside those two counties, DATCP Food Licensing on 608-224-4923 will identify the right state, county or city agent for your site.

Cottage food is not a route here

Wisconsin has two familiar home food exceptions and neither one reaches fresh microgreens.

The home bakery exception comes from litigation, not from a produce rule, and DATCP describes it as applying only to non-potentially-hazardous baked goods sold directly to consumers. Everything else made in a commercial kitchen business must comply with ATCP 70 or ATCP 75.

The Pickle Bill covers home-canned naturally acidic or acidified fruits and vegetables at pH 4.6 or lower, capped at $5,000 per year per person. The cap is fixed rather than inflation adjusted, and DATCP publishes no last legislative change date for it. Fresh raw microgreens are not a canned acidified product, so it is simply the wrong number for this business. It also expressly forbids internet and out-of-state sales, worth knowing before anyone cites it at you as an e-commerce route.

You do not need either one. Wisconsin's produce category is broader than both, and it is the mechanism that actually fits.

Food safety, inspections and the free on-farm review

The state overlay. DATCP licensing and inspection, ATCP 75 for retail food, ATCP 70 for wholesale processing. The concrete trigger is processing, and the definition is the one already quoted: cutting, packing, packaging.

Who inspects. For a licensed retail or processing facility, DATCP or its local agent. For a covered produce farm, Safe Wisconsin Produce staff announce the Produce Safety Rule inspection, and qualified-exempt farms can receive a limited-scope review of eligibility records and notice requirements. A new operation, a change in processing, a complaint or illness investigation, or a failure to meet license conditions can each prompt one.

How often. Not published for microgreens. Frequency depends on facility type, risk, and whether a local agent licenses you. Ask DATCP Food Licensing on 608-224-4923, or the Dane or Milwaukee agency if that is your jurisdiction.

Food manager certification, and a quiet win. Most licensed retail food establishments need a certified food protection manager, with 90 days for a new establishment or a change of operator. But DATCP explicitly exempts establishments handling only fresh fruits or produce, along with prepackaged retail food establishments, transient events and micro markets. So a produce-only operation, even a licensed one, does not need the certificate. A cut or processed retail operation should assume certification applies unless DATCP confirms otherwise.

The free review, and it is the best first call. DATCP administers Safe Wisconsin Produce, the state's Produce Safety Rule program, and it offers a voluntary, confidential, non-regulatory On-Farm Readiness Review at no cost. It runs about 2.5 hours, is offered June to October, and is first come first served on 608-224-4511 or safeproduce@wi.gov. It is not an audit and not a pre-inspection, and it covers hygiene, soil amendments, animals, water, harvest and postharvest practices. DATCP names University of Wisconsin Extension as a technical assistance partner afterwards. For a small microgreens farm it is the most useful formal check available.

Water. For a fully covered farm, DATCP's covered farms fact sheet publishes the agricultural water controls: water contacting covered produce must have no detectable generic E. coli, and on detection you discontinue use and correct before reuse. For water applied directly to growing produce, the geometric mean threshold is 126 CFU generic E. coli per 100 mL, alongside a statistical value threshold. For untreated surface water, the guidance calls for at least 20 samples over 2 to 4 years initially, then five per growing season. Two cautions: these are federal standards implemented by Wisconsin rather than fixed state figures, so they move when the federal rule moves, and a sales-exempt farm is not automatically inside the testing program. Ask Safe Wisconsin Produce on 608-224-4511 for your farm's coverage before budgeting for tests.

The federal figures. Take them from FDA, not a state summary. FDA publishes $34,324 as the three-year 2023 to 2025 average produce-sales value below which a farm is not covered, from a $25,000 baseline in 2011 dollars, and $686,476 on the same basis for the qualified exemption. Both come from the column headed "Average 3 Year Value for 2023 - 2025". The single-year 2025 values printed beside them, $35,247 and $704,950, are a different measure and must never be quoted as the three-year figure. Keep dated sales records and review your status annually.

Labeling

Wisconsin publishes no exhaustive state microgreens label list for a raw intact product. What it does publish sits on the produce safety side. For a qualified-exempt farm under the federal rule, the farm name and complete business address must appear at the point of sale. Where a product label is otherwise required, DATCP says it must carry:

For a licensed processed or cut product, DATCP requires it to be "fully labeled", and the working framework is the federal commercial food label: common name, net quantity, an ingredient list where applicable, a major allergen declaration where applicable, the responsible firm's name and address, and Nutrition Facts unless an exemption applies. A single-variety pack usually needs no ingredient list beyond the identity statement, which is not a reason to skip the rest.

On "Keep Refrigerated": no mandatory Wisconsin phrase is published. DATCP's event guidance notes that a license may be needed where food must be cold held at 41 degrees Fahrenheit or below for safety, and puts cut and processed vegetables on the commercial route. Use accurate storage instructions, maintain the cold chain the product needs, and get the real label reviewed by DATCP Food Licensing on 608-224-4923 before a print run, because there is no published Wisconsin-only checklist to check yourself against.

Tax, and the permit you probably do not need

Fresh microgreens sold as food ingredients are generally exempt from Wisconsin sales tax. Wisconsin DOR Publication 220 says food and food ingredients for human consumption are exempt, except for prepared food, candy, dietary supplements and soft drinks, and it identifies vegetables as exempt food and ingredients. A raw bag of pea shoots is not any of the four exceptions.

The useful consequence: no seller's permit. DOR says a seller's permit is required for taxable retail sales unless all of your sales are exempt, so a grower whose entire product line is exempt fresh produce stays out of that system. Compare Tennessee, where registration is required above a monthly sales average even though the product itself is exempt. That changes the moment you sell something taxable alongside the greens, so watch the merchandise table and the prepared-food line.

A resale certificate is a buyer's document for a qualifying purchase for resale. It is not required merely to sell exempt fresh produce.

Business setup

Wisconsin does not require a special statewide business entity just to grow and sell raw intact microgreens. A sole proprietor can operate without forming anything, and LLC, corporation or DBA is a business-structure decision rather than a food-law one. The food license arrives only when the product, process or channel triggers it, while local business registration and zoning apply on their own terms.

Formation and local business license costs are not published in an official Wisconsin fee source. Ask the Wisconsin Department of Financial Institutions and your city clerk before budgeting a figure, and do not take a number from a third-party formation site as a state fee. Food license costs are separate and are published: $95 a year for a Food Processing Plant under $25,000 in annual production, with higher bands for potentially hazardous status.

Selling channel by channel

Farmers markets. A farmer selling their own raw intact microgreens needs no food license under DATCP's produce table. That is the state answer, not the whole answer: market rules routinely require a vendor application, insurance, attendance commitments, packaging standards and proof of any license you do hold, and the market enforces those as private terms. If you cut, mix, cook, package as processed food, or sell something needing cold holding for safety, DATCP says a license may be needed at the making location, at the event, or both. Ask Food Licensing on 608-224-4923, which will point you at the right state, county or city agent for the site.

Restaurants. This is where Wisconsin is genuinely generous. Wholesale to a restaurant does not by itself end the exemption, because DATCP's guide covers a producer distributing raw intact vegetables from the farm to a restaurant. For cut or processed greens, the finished product has to come from your own licensed retail food establishment or food processing plant, so the license attaches to where the product was made rather than to the fact of wholesaling.

Chefs will still want clean invoices, farm identity, harvest and lot traceability, consistent product condition and reliable temperature control. And if you are a federally qualified-exempt farm, a restaurant in Wisconsin or within 275 miles counts as a qualified end user, but you must retain the eligibility records and display farm name and address.

Grocery. The same exemption applies to farm-to-store raw intact product. Buyer requirements go further than the law almost every time: vendor approval, product liability insurance, invoice and lot traceability, recall cooperation, cold chain specifications, and sometimes GAP certification or a third-party audit. DATCP itself notes that retail and food-service industries use third-party audits to verify supplier GAP and GHP practices, so treat that as expected rather than exceptional. No statewide buyer insurance limit, audit certificate or grocery checklist is published. Get the written contract before you set a price or promise availability.

Online. Ordering online does not change the product's classification. Raw intact greens can be sold online if the food, tax, carrier and destination requirements are met; a processed product still needs its Wisconsin retail or processing license. Crossing a state line adds the destination state's registration and food code plus tax nexus, and the federal analysis continues unchanged. No universal interstate microgreens permit is published, so ask DATCP Food Licensing on 608-224-4923 and the destination state's agriculture or health agency before accepting the order. And do not reach for the Pickle Bill: it expressly forbids internet and out-of-state sales.

Home growing and zoning

There is no statewide home-microgreens zoning clearance in Wisconsin, and no all-city list exists. Check home occupation, building, fire, water and wastewater, lease and HOA rules at the actual growing address. The relevant office is your local zoning administrator, not DATCP.

Farmland preservation zoning is a separate structure and is locally crafted, so a certified district can be more restrictive than the state baseline. It limits land to agricultural and compatible uses under local ordinances, and tax credit eligibility requires local compliance. DATCP directs landowners to the local zoning administrator to determine what applies to a parcel. Farmland preservation status does not waive food licensing, and Wisconsin offers zoning and tax credit structures rather than a blanket right-to-farm defense that excuses food or land-use law. Do not rely on agricultural status to run a commercial cut-greens facility where it is prohibited.

A commercial kitchen is not automatically triggered by growing microgreens, and a live or intact tray does not inherently require one. Processing does: cutting, mixing, packing or packaging can be food processing, and cut product sold from the farm requires a retail food establishment license and commercial kitchen. Before installing a wash and pack room or renting shared kitchen space, describe the actual flow to DATCP, which asks applicants what is in the product, where it will be made, and how it will be packaged and sold.

Insurance

No general Wisconsin statutory product liability insurance requirement for a microgreens grower is published, which makes cover sound risk management rather than a legal condition of selling. Ask DATCP Food Licensing on 608-224-4923 and your local market or city for a specific venue. Worth carrying: general liability plus product and completed-operations cover, and where relevant property or crop cover, delivery vehicle cover and workers' compensation.

DATCP makes one point directly: licensing does not eliminate liability. A processor remains legally liable for the food it sells regardless of licensing status, so an exemption is not a shield.

Restaurant and grocery contracts commonly require a certificate of insurance, additional insured status, a specified product liability limit, product specifications, traceability and recall cooperation, food safety practices and cold chain performance. They may ask for GAP or audit evidence where no law requires it. No statewide mandatory limit or certificate is published, so the buyer's agreement controls. Secure it before committing to wholesale volume.

What Wisconsin does not publish

The market

No population, density or microgreens count is carried here, because no official Wisconsin figure for any of them was verified. Borrowing a number from elsewhere and presenting it as checked would be worse than saying less, so here is what Wisconsin's own agency material supports.

Wisconsin has real direct-market capacity and all of it is legally open without a food license. Farmers markets, CSA and direct sales, restaurant purchasing and grocery buyers can each take producer-grown raw intact vegetables with nothing in the way. Most states force a choice between the easy channel and the profitable one. Wisconsin does not.

The counterweight is the season. A short outdoor growing season makes controlled-environment production and reliable winter delivery a real differentiator, because a chef who can only get local greens from May to October has a gap you can fill. The same channels bring competition from local farms, indoor growers, distributors and established market vendors, so lead with the winter argument.

The strategic read follows from the rule. Because the exemption is a product category rather than a channel exemption, you can build an entire wholesale business, restaurants and grocers included, without a food license, provided the greens stay raw and intact. That is a different growth path from Iowa, where cutting forces the license, or Indiana, where selling to a restaurant ends the exemption.

So stage it. Start with intact trays or plain stem-cut raw product to keep the simple exemption. Add a licensed wash and pack operation only when buyer demand pays for compliance, labor, packaging, refrigeration, insurance and delivery. At $95 a year for the entry processing band, the fee is never the obstacle; the operating cost behind it is.

Do not rely on a city-specific restaurant or competitor count without a current directory or a field check. Test with preorders from chefs, co-ops and CSA members, and document harvest lot, delivery temperature and repeat order rate from the first week.

On funding, DATCP runs Specialty Crop Block Grants. The 2026 announcement described project grants of $10,000 to $100,000, with applications submitted by 3 March. Eligible applicants include nonprofit and producer organizations, governments, universities and agricultural groups, and grants must benefit the industry rather than deliver direct profit to one person or business. That last condition matters: it is not a grant for your farm, it is a grant for work that helps growers generally.

Frequently Asked Questions

Q: Do I need a license to sell microgreens in Wisconsin? A: Not while they are raw and intact. DATCP's Local Food Marketing Guide lists raw intact fruits and vegetables (excludes sprouts) as needing no license from the producer. Cut, wash, strip or bag them as ready to eat and you are into the retail or processing license framework.

Q: Can I really sell to restaurants and grocery stores with no license? A: For raw intact product, that is what the guide says. It covers producer sales from the farm, door to door, at markets, and to a grocery store, restaurant or institution. The exemption follows the product, not the buyer, which is the same shape as Minnesota and the opposite of Indiana and Oregon.

Q: Is a live tray treated differently from cut greens? A: Yes, because the product's condition is the whole test. A live tray is an intact growing plant. Cut greens are potentially a processed food. There is no verified special live-tray license, so present a tray as an uncut plant product and get DATCP's classification rather than assuming it.

Q: Is there a sales figure that keeps me exempt? A: No. The rule is product and activity based, not a dollar cap. The $5,000 figure people quote is the Pickle Bill, which covers home-canned acidified food and forbids internet and out-of-state sales. It has nothing to do with fresh greens.

Q: Can I use a cottage food law? A: No. Wisconsin's home bakery court exception reaches only non-potentially-hazardous baked goods sold direct, and the Pickle Bill reaches only home-canned acidic and acidified products. Fresh microgreens are neither. You do not need either one, because the produce category is broader.

Q: Do I need a seller's permit for sales tax? A: Probably not. Fresh vegetables are exempt food and food ingredients under DOR Publication 220, and DOR requires a seller's permit only where you make taxable retail sales. If every sale you make is exempt, you stay out of the system. Selling anything taxable changes that.

Q: Do I need a certified food protection manager? A: Not for a produce-only operation. DATCP exempts establishments handling only fresh fruits or produce, along with prepackaged retail establishments, transient events and micro markets. If you run a cut or processed retail operation, assume it applies unless DATCP confirms otherwise.

Q: What is the single best first call? A: 608-224-4511, Safe Wisconsin Produce, and book the free On-Farm Readiness Review. It is voluntary, confidential, non-regulatory, about 2.5 hours, offered June to October, and costs nothing.

Final thoughts

Wisconsin gives you a category and asks you to stay inside it. Raw. Intact. Not sprouts. Do that, and the state does not care whether the buyer is a neighbor at a market stall or a grocery chain's produce buyer, which is a wider license-free lane than most states in this series offer.

Three things to carry. Ask DATCP to classify your specific harvest, wash, bag and refrigeration model before you scale, because "intact" is the whole exemption and DATCP decides it from your description rather than from a published test. Ignore the $5,000 Pickle Bill figure completely; it belongs to a different law and quoting it at a market manager will only confuse the conversation. And if you are in Dane or Milwaukee county, your licensing and inspection relationship may sit with the county rather than the state, so start there rather than with the state list.

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