When scanning the aisles for groceries, you’ve probably seen a variety of symbols and seals printed on food packaging. These aren’t just decorative—they’re certification marks, awarded by independent organizations to signify that the product meets specific standards for quality, sourcing, or dietary restrictions.
In this post, we’ll break down some of the most common third-party certification marks you’ll find on food products and packaging, so you can shop with more clarity and confidence.
1. USDA Organic – United States
1.1 What Is the USDA Organic Seal?
The USDA Organic seal is an official certification mark issued by the United States Department of Agriculture (USDA) through its National Organic Program (NOP).
It is used to identify food and agricultural products that meet strict organic farming and processing standards defined by federal law.
This seal is one of the most trusted and recognized indicators of organic integrity in the U.S. market.
1.2 What Does It Mean?
When you see the USDA Organic label on a product, it means:
- The product is made without synthetic fertilizers, pesticides, genetically modified organisms (GMOs), antibiotics, or growth hormones.
- It is grown and processed using natural and sustainable farming practices.
- The entire supply chain—from farm to packaging—has been certified by an accredited third-party certifying agent under the USDA’s National Organic Program.
USDA Organic Seal Design
The seal features:
- A green and white circular badge
- The words “USDA ORGANIC” in bold capital letters
- Often appears on the front of food packaging
1.3 Certification Categories
The USDA allows four types of organic labeling, each with its own rules:
| Label | Meaning |
| 100% Organic | Made with only certified organic ingredients (excluding water & salt) |
| Organic | Contains 95% or more organic ingredients |
| Made with Organic | Contains at least 70% organic ingredients (no USDA seal allowed) |
| Less than 70% Organic | May list organic ingredients but no organic label or seal permitted |
Why It Matters?
The USDA Organic seal gives consumers confidence that:
- The product has been independently verified
- It adheres to ecological, health-conscious, and ethical standards
- It supports sustainable agriculture and avoids harmful synthetic inputs
Extra Notes:
- Certification is required for any business labeling products as organic.
- Violations, such as false claims or misuse of the USDA Organic seal, can result in fines up to $11,000 per violation.
- Organic certification must be renewed annually and includes on-site inspections.
2. EU Organic Logo (Euro Leaf)
2.1 What Is the EU Organic Logo?
The EU Organic Logo is the official mark used across the European Union to identify certified organic food and farming products.
It represents compliance with the EU Organic Regulation, which sets strict standards for environmentally friendly farming, animal welfare, and the prohibition of most synthetic chemicals and GMOs.
The logo is often called the “Euro Leaf” due to its design: a green background with a leaf shape formed by 12 white stars (symbolizing the EU).
2.2 What It Means?
Products bearing the EU Organic Logo have been:
- Certified by an approved EU control body or authority
- Produced according to organic farming principles and sustainable practices
- Free from genetically modified organisms (GMOs)
- Grown with limited use of synthetic pesticides and fertilizers
- Processed without artificial additives or preservatives (with few exceptions)
The logo applies to both food and beverage products that are at least 95% organic in content.
Logo Appearance
- Design: A stylized leaf made of 12 stars (symbolizing the EU flag)
- Color: Typically green background (Pantone 376), but can appear in black or white if color printing is not possible
- Shape: Rectangular, with a minimum size requirement of 9 mm height and 13.5 mm width
Additional Requirements
When the logo is used on packaging, it must be accompanied by:
- The code number of the certifying control body (e.g., FR-BIO-01)
- The place of origin of the raw materials (e.g., “EU Agriculture,” “Non-EU Agriculture,” or “EU/Non-EU Agriculture”)
2.3 Legal and Regulatory Context
- The logo is mandatory on all prepackaged EU organic foods.
- Use of the logo is governed by EU Regulation (EU) 2018/848 on organic production and labeling.
- Unauthorized or misleading use of the logo is subject to penalties and enforcement actions.
Where It Applies?
The EU Organic Logo is valid across all EU member states and recognized by many international markets. It helps consumers quickly identify products that meet consistent organic standards, supporting transparency and sustainable agriculture.
3. Halal & Kosher Certification
Religious Dietary Certifications for Food Products.
Halal and Kosher certifications indicate that a food product has been prepared in accordance with religious dietary laws.
These certifications are especially important for Muslim and Jewish consumers, respectively, and are often required for exporting food to certain countries or serving diverse populations.
While they have different religious origins and rules, both certifications promote clean, ethical, and traceable food preparation.
3.1 What Does “Halal” Mean?
“Halal” is an Arabic word meaning “permissible”. In the context of food, it refers to items that are lawful for Muslims to eat under Islamic law (Sharia).
Requirements for Halal Certification:
- Animal products must be from animals slaughtered according to Islamic rites (Zabiha), including a prayer during slaughter.
- Prohibits pork and pork by-products
- No alcohol or intoxicants
- Equipment and utensils must be clean and not cross-contaminated with non-halal substances
3.2 Certification Bodies
Examples include:
- JAKIM (Malaysia)
- Halal Monitoring Authority (HMA) – Canada
- Islamic Food and Nutrition Council of America (IFANCA)
- Majelis Ulama Indonesia (MUI)
Certified products usually display a Halal symbol issued by the certifying body:
- A crescent moon and the word “Halal” in Arabic or English
- The logo of the specific certifying agency
4. Non-GMO Project Verified – USA/Canada
4.1 What Is It?
The Non-GMO Project Verified label is a third-party certification mark that indicates a product has been tested and verified to be free from genetically modified organisms (GMOs) to the highest North American standard.
This mark is one of the most recognized and trusted non-GMO labels in the U.S. and Canada.
Symbol and Meaning
- The logo features a butterfly on a blade of grass with the words “Non-GMO Project VERIFIED.”
- The butterfly symbolizes natural purity and freedom from genetic modification.
- Seeing this logo means the product has undergone a rigorous verification process.

4.2 What Does It Guarantee?
Products with this seal have been:
- Evaluated through ingredient testing, supply chain audits, and manufacturing reviews
- Found to meet the Non-GMO Project’s standards for GMO avoidance
- Verified to contain less than 0.9% GMO content, aligning with the EU threshold for labeling
- It applies to food, supplements, body care, and animal feed.
4.3 How Is It Verified?
Verification involves:
- Ingredient Review – Ensures that none of the ingredients are at high risk for GMO contamination (e.g., corn, soy, canola).
- DNA Testing – Lab tests are used for high-risk ingredients to detect the presence of GMOs.
- Traceability & Segregation – Supply chains must be documented and designed to keep GMO and non-GMO products separate.
- Ongoing Compliance – Companies must submit to annual reviews and spot checks.
4.4 Why It Matters?
GMOs are widely used in North American agriculture, especially in crops like corn, soybeans, canola, and sugar beets. Many consumers prefer to avoid GMOs due to:
- Health concerns (though scientific consensus finds GMOs safe)
- Environmental impact (e.g., pesticide resistance)
- Ethical or labeling transparency reasons
The Non-GMO Project Verified label gives consumers a clear, science-backed way to choose GMO-free products.
5. Gluten-Free Certification
5.1 What Is It?
Gluten-Free Certification is a third-party verification system that ensures a product does not contain gluten or is free from gluten contamination within strict limits. This certification is especially important for people with celiac disease, non-celiac gluten sensitivity, or those who choose to follow a gluten-free diet.
It gives consumers confidence that the product is safe to consume and has been independently tested and verified.
What Is Gluten?
Gluten is a group of proteins found in:
- Wheat
- Barley
- Rye
- And derivatives of these grains (like malt, spelt, or triticale)
In sensitive individuals, gluten can cause digestive damage, immune reactions, or discomfort.
5.2 Certification Standards
To earn gluten-free certification, products must meet strict thresholds for gluten content:
- Less than 20 parts per million (ppm) of gluten in the final product — in line with FDA and international standards.
- Some programs are even stricter, requiring <10 ppm.
5.3 Leading Certification Organizations
There are several major organizations that offer recognized gluten-free certification:
| Organization | Symbol Example | Standard |
| Gluten-Free Certification Organization (GFCO) | GF logo with a grain symbol | <10 ppm |
| Celiac Support Association (CSA) | CSA seal with wheat crossed out | <5 ppm |
| NSF Gluten-Free Certification | NSF/Gluten-Free mark | <20 ppm |
| Beyond Celiac (partners with GFCO) | May use GFCO seal | <10 ppm |
Each of these logos indicates that the product was tested and audited under that organization’s protocols.
5.4 How Certification Works
- Ingredient Review – Verifies that no gluten-containing ingredients are used.
- Facility Audit – Ensures no cross-contact with gluten during manufacturing.
- Lab Testing – Periodic tests confirm gluten levels are below required thresholds.
- Ongoing Compliance – Certified products are regularly reviewed and inspected.
5.5 Labeling on Packaging
Certified gluten-free products usually feature a recognizable logo such as:
- “GF” inside a circle or square
- A wheat symbol with a slash through it
- Text such as “Certified Gluten-Free” clearly visible on the package
Note: “Gluten-Free” and “Certified Gluten-Free” are not the same. Certified products have been independently tested, while a “gluten-free” label alone may be self-declared by the manufacturer.
