The microgreens industry continues to expand. As soon as you shift from hobby grower to a commercial producer, certifications become essential. Whether you sell through farmers markets, grocery stores, or wholesale distributors, having proof of safe and responsible practices builds trust and supports growth.
Certifications might seem complicated, with labels like Organic, GAP, HACCP, FSMA, and more, but understanding what is needed helps you make clear decisions. This guide focuses on what is essential for microgreen growers in the United States, along with optional programs you might consider.
Core Certifications for Microgreen Growers in the United States
1. USDA Organic Certification
If you plan to sell your microgreens as organic, USDA Organic certification is mandatory. This verifies that your production follows federal rules for approved inputs, safe water, and traceable records.
Even if you grow soilless, you can still apply by documenting that your water and substrates are clean. Some growers have found that maintaining simple, clear records about their water testing and sourcing organic seeds made their inspections easier and less stressful.
If you claim your microgreens are organic and sell more than $5,000/year, you must be certified.

2. Good Agricultural Practices (GAP)
GAP certification covers food safety across your entire process, from planting and harvesting to packing and storing. Auditors check details like water testing, worker hygiene, and traceability systems.
Many wholesale buyers expect GAP so they can confidently stand behind the products they offer their customers. Several microgreen farms have streamlined their GAP prep by switching from soil to clean, pathogen-reduced substrates, cutting down risk during inspections.

3. Hazard Analysis Critical Control Point (HACCP)
HACCP is a food safety management system that identifies hazards and sets up critical control points to prevent them. Microgreen growers that process ready-to-eat salad mixes often need HACCP to prove they control risks at each step.
A grower packaging assorted microgreens for meal-prep businesses shared that HACCP certification helped them win bigger accounts because buyers trusted their documented safety plan.

Secondary Certifications to Consider
Food Safety Modernization Act (FSMA) Compliance
FSMA is not a certification you display, but it is federal law. It covers food safety for any farm distributing food products in the United States. If you ship across state lines or sell to wholesalers, you must comply with FSMA, which addresses water safety, traceability, and sanitation practices.

Local Health Department Licenses
Your state or county might require a food handler license or specific inspections. In some areas, microgreens are grouped with sprouts, which means they need regular water testing and possibly lab verification. Always check with your local agency so you can operate with confidence.
Tip: Connect with your local cooperative extension office for help interpreting rules, since they often offer free guidance.
Third-Party Food Safety Certifications
If you plan to serve large national grocery chains, advanced certifications like SQF (Safe Quality Food) or PrimusGFS can build even more trust. These programs have detailed audits covering sanitation, recordkeeping, and emergency recall plans.
A grower in Pennsylvania who upgraded to SQF shared that it took a few months of preparation, but allowed them to double their sales with regional retailers.

Non-GMO Verification
If you want to market a non-GMO product, certification helps confirm you are using approved seeds and inputs. It is not required, but can strengthen your brand for health-conscious shoppers.
Sustainability Certifications
While optional, eco certifications support your brand. Labels like Certified Naturally Grown or Fair Trade can show customers that you uphold high environmental and social values. They work especially well for farmers market vendors, where customers appreciate a personal story and authentic practices.
Choosing Which Certifications to Pursue
Certifications help protect your business, reassure buyers, and even prevent costly liability issues. Here is a simple breakdown to help you choose:
-
Farmers markets: Check with your county health department for licensing. GAP can help, but is usually not mandatory.
-
Wholesale buyers of groceries: GAP plus FSMA compliance will meet most expectations.
-
Value-added or prepackaged products: HACCP and possibly SQF build trust with larger foodservice accounts.
Tip: Simplify your recordkeeping from the start by using pathogen-free, uniform grow mats like Vegbed bamboo fiber substrates. These mats keep the product cleaner and safer, which supports certifications.
Additional Considerations for Microgreen Growers
Seed Source Certifications
If you are pursuing organic or non-GMO labels, your seeds must meet those standards too. Look for seed vendors that provide documentation such as USDA Organic or Non-GMO Project Verified certificates. Keep these records on file, especially if undergoing a third-party audit.
Water Quality Standards
Since microgreens are often consumed raw, irrigation water safety is non-negotiable. Many states require water testing to detect pathogens like E. coli. Some growers test their water every quarter and store lab results in a digital file for easy access during audits.
Building a Broader Food Safety Plan
In addition to certifications like GAP or HACCP, it's important to develop a food safety plan tailored to your farm. This includes:
-
Sanitation procedures for trays and tools
-
Storage and handling protocols
-
Labeling practices and batch tracking
-
Emergency recall systems
A well-documented plan helps ensure every team member knows what to do, and it shows buyers you're serious about safety.
Don’t Overlook State and Local Permitting
Certifications get a lot of attention, but you also need to comply with licensing and local regulations. These vary by state and even county. For example:
-
In New York, packaging microgreens may require a food processing license.
-
In New Jersey, live tray sales may fall under nursery or greenhouse regulations rather than food handling laws.
Before selling, always contact your local Department of Agriculture and health department to confirm what applies to your farm.
Licensing Before Launch
Beyond food safety and certification, make sure your business is properly licensed. Here’s a short checklist:
-
Business registration with your state
-
Sales tax permit, if applicable
-
Food handler or processing permits for your county
-
Nursery license for live microgreens, if required
Handling these basics early helps you avoid penalties and build credibility with buyers.
Final Thoughts
Certifications might seem complex at first, but they are a tool for building a safer, more profitable, and professional microgreens business. Buyers and consumers increasingly look for transparency and evidence of clean growing practices. USDA Organic, GAP, HACCP, and FSMA give you a foundation to scale your operation confidently.
