Is there an official gluten-free logo?

Gluten-free diets have become increasingly popular in recent years, with more and more people avoiding gluten for medical reasons or by choice. For those who need to follow a strict gluten-free diet, being able to easily identify gluten-free products is very important. This leads many to wonder – is there an official gluten-free logo that can be found on certified gluten-free foods?

What is gluten?

Gluten is a general name for the proteins found in wheat, rye, barley and triticale. It helps foods maintain their shape and texture, but it can cause serious health issues for those with celiac disease or non-celiac gluten sensitivity.

For people who cannot tolerate gluten, following a gluten-free diet is the only treatment option. This means avoiding any foods, beverages or medications that contain gluten.

Common sources of gluten

In addition to foods made from wheat, rye and barley, gluten is commonly found in:

  • Baked goods – breads, cakes, cookies, crackers, etc.
  • Pasta
  • Cereals
  • Beer
  • Salad dressings and sauces
  • Seasonings
  • Soups and gravies
  • Processed meat products – hot dogs, sausages, etc.
  • Fried foods that are dusted with flour

It’s also important to watch out for cross-contamination, where gluten is accidentally transferred from a gluten-containing food to a gluten-free food.

The need for an official gluten-free certification

When you’re shopping for gluten-free products, how can you know for sure that something is truly gluten-free? Terms like “gluten-free” and “no gluten ingredients” are not regulated, so any manufacturer can make these claims.

This is why an official gluten-free certification program is so important. A certification logo indicates that the product has been tested to verify it meets the requirements for gluten-free status.

Benefits of an official gluten-free logo

An easily recognizable gluten-free logo on food packaging provides the following benefits:

  • Takes the guesswork out of identifying safe foods
  • Reduces risk of accidentally consuming hidden gluten
  • Gives peace of mind when shopping and eating
  • Ensures products meet gluten-free standards for ingredients as well as manufacturing processes
  • Holds manufacturers accountable for making accurate gluten-free claims

Without an official certification program, it is very challenging for those trying to avoid gluten to know which products they can trust. A consistent logo makes the process much simpler.

Gluten-free certifications around the world

A number of countries have established official gluten-free certification programs. Here is an overview of some of the major gluten-free logos you may see printed on product packaging:

United States

The gluten-free certification program in the U.S. is voluntary. Products certified as gluten-free must contain less than 20 parts per million (ppm) of gluten. The FDA recognizes the following logos:

Certification Program Logo
Gluten-Free Certification Organization (GFCO)
Celiac Support Association (CSA)
Gluten Intolerance Group (GIG)


Canada has mandatory standards for gluten-free claims. Any food labeled “gluten-free” must meet these federal guidelines:

  • No wheat, triticale, rye, barley or oats*
  • Less than 20 ppm of gluten from cross-contamination

*Oats are allowed if specifically labeled “certified gluten-free oats”

The Canadian Celiac Association issues the following gluten-free certification:

Certification Program Logo
Canadian Celiac Association


The European Union has standardized regulations for gluten-free claims. Foods labeled as “gluten-free” must not exceed 20 ppm of gluten.

Products certified as gluten-free will display one of these logos:

Certification Program Logo
Associazione Italiana Celiachia (AIC)
AOECS Standard

Australia and New Zealand

The regulatory standard for gluten-free foods is “no detectable gluten.” Certified products will display one of the following logos:

Certification Program Logo
Coeliac Australia
Coeliac New Zealand

Is there one universal gluten-free logo?

Unfortunately, at this time there is no single unifying gluten-free logo that is recognized around the world. The logos used vary between countries.

However, the International Organization for Standardization (ISO) has developed a global standard for gluten-free claims. While not a logo itself, this ISO standard does establish accepted requirements for when a food can be labeled as gluten-free. The ISO defines gluten-free as:

  • No ingredients that contain wheat, rye, barley, oats* or their crossbred hybrids
  • Less than 20 ppm of gluten

*Oats must be gluten-free

So in the future, we may possibly see movement toward one international gluten-free logo based on this ISO standard. But for now, the logos recognized in each country remain the best way to identify certified gluten-free foods locally.

Can manufacturers just create their own gluten-free logo?

Companies can develop and display their own proprietary gluten-free logo on products. However, for a logo to carry meaningful weight and be trusted by consumers, it needs to be backed up by certification.

Any reputable gluten-free certification program requires testing of both individual ingredient components as well as the finished product. Detailed audits are conducted of manufacturing facilities and processes to ensure there is no risk of cross-contamination. Only products meeting very strict standards can display the official certification logo.

So a manufacturer can create a “gluten-free logo” to put on their packages, but for it to provide credibility and confidence, it should align with established certification protocols.

Should oats have their own gluten-free logo?

Whether or not oats require a separate gluten-free logo is a frequently debated topic in the celiac community.

Oats do not naturally contain gluten. However, they are very often cross-contaminated with wheat and barley during growing and processing.

Many countries require oats labeled as gluten-free to have purity standards ensuring uncontaminated processing. But there is still dispute over whether “certified gluten-free oats” need a distinctive logo to distinguish them from regular oats.

Those in favor argue that a unique oats logo provides added transparency for the benefit of the consumer. But others believe creating another logo unnecessarily complicates food labeling. Both perspectives have valid points in this ongoing discussion.

Arguments for a special gluten-free oats logo

  • Clearly designates oat products that are uncontaminated
  • Gives added certainty for gluten-sensitive individuals who react to oats
  • Holds manufacturers accountable for purity controls

Arguments against a special gluten-free oats logo

  • Adds complexity to labeling when uniformity is preferable
  • May imply oats are less safe than other gluten-free grains
  • Regulatory standards already exist in many regions
  • Extra logo could lead to consumer distrust of certified gluten-free oats

This issue continues to spark discussion within the medical community. But whether or not a distinct gluten-free oats logo emerges, clear labeling remains paramount for consumer safety.

Should a gluten-free logo signify other attributes?

Another topic of debate is whether a gluten-free logo should indicate additional food qualities beyond just the lack of gluten. For example, should an official logo also certify that food is:

  • Organic?
  • Non-GMO?
  • Free of allergens like dairy, nuts, etc?
  • Low FODMAP?
  • Whole grain?

There are arguments on both sides of this issue. Some individuals feel that gluten-free certification should focus only on verifying the absence of gluten. They point out that consumers with different diet needs and restrictions could find additional labels confusing.

On the other hand, many people following gluten-free diets have multiple food sensitivities. A logo that indicates a product is also free of other allergens or additives could provide meaningful information. People with celiac disease often have related conditions like lactose intolerance or irritable bowel syndrome that benefit from a low FODMAP diet.

But the counterpoint is that too many factors on one logo may dilute its effectiveness. There are also cost considerations for manufacturers. Testing for gluten alternatives beyond gluten becomes more complex and potentially prohibitive.

While expanded attributes could give consumers more data, a logo that tries to certify too much at once risks becoming muddled. There are merits to keeping the focus specifically on gluten-free verification for clarity.

How are gluten-free certification programs enforced?

For a certification program to be credible, there must be measures in place to enforce compliance and prevent fraudulent use of the gluten-free logo. This is done through regular auditing and product testing.

Once a food manufacturer has been approved to use a certification logo, their facility, processes and finished products undergo periodic reviews. Samples are analyzed to ensure they continue to meet the standards. If issues are found, the manufacturer must address them to retain certification.

Certification organizations also respond to consumer complaints of illness from supposedly gluten-free products. They may launch investigations or withdraw certification if companies are found not complying with requirements.

There are legal penalties associated with misusing a registered gluten-free logo. These disincentives help deter manufacturers from making false claims.

While voluntary, compliance is encouraged by the clear sales advantage to food producers of displaying a trusted gluten-free label. Most consumers trying to avoid gluten seek out these logos when shopping.

Gluten-free label regulation challenges

Despite efforts of certification bodies, some level of fraudulent gluten-free claims still occurs. Reasons include:

  • Smaller companies circumventing certification testing requirements
  • Online-only brands with no retail presence
  • Foreign imports with questionable manufacturing methods
  • Lack of staffing to closely monitor all producers

Additionally, restaurants making gluten-free menu claims often do so without any official oversight. This increases the potential for cross-contamination with gluten-containing foods in the kitchen.

There is certainly room for improved education, regulations and enforcement around gluten-free labels. But certification logos are a valuable tool for identifying trustworthy products.

Should gluten-free labels have a “may contain traces of gluten” warning?

Some have called for gluten-free labels to include disclaimers if there is a chance of cross-contamination with gluten during manufacturing. Similar advisories are sometimes seen for common allergens like “may contain milk.”

However, deliberately adding “May contain gluten” warnings goes against the very purpose of certification labels. These logos are intended to show the product definitively does not contain any traces of gluten within established limits.

If the gluten-free status of a food is uncertain, it should not display an official logo at all. While zero risk cross-contamination is difficult, proper protocols can get extremely close through segregated facilities and equipment.

For the highest safety, the most sensitive individuals should still contact manufacturers and discuss their production procedures. But for the majority following a gluten-free diet, certification logos meaningfully identify foods free of any traces based on stringent gluten testing.


While there is not currently one universal gluten-free logo, many countries have official certification programs with identifiable logos. These enable consumers shopping for gluten-free products to more easily recognize which foods meet regulated standards and are safe to consume.

Certification also holds food companies accountable for properly labeling gluten-free items. Standards and enforcement continue improving, though isolated incidents of misuse still occur. Overall, an official gluten-free logo offers meaningful assurance when available on product packaging.
