AFDIAG, AIC, FACE, Coeliac UK: Who Certifies What?

A crossed grain symbol on a pasta packet, an association sticker on a restaurant door, a national logo on a bag of flour: the “official” signs of gluten-free food look similar, but they don’t guarantee the same thing. Behind each one stands a national coeliac association — and understanding who certifies what tells you exactly how much trust to place in each logo.

The crossed grain: a European symbol, national licences

The best-known logo is the Crossed Grain. Contrary to a common assumption, it isn’t a simple decorative pictogram: it’s a registered trademark, owned by the AOECS (Association of European Coeliac Societies), the European federation of coeliac associations. A manufacturer can’t print it freely — they must obtain a licence, granted after audit and testing, through their country’s coeliac association.

In practice, a product bearing the official crossed grain has been checked against a shared specification (gluten content below 20 mg/kg, controlled production), with a licence number that makes it traceable. That’s a step above the simple regulatory “gluten-free” claim, which is the manufacturer’s own responsibility with no outside audit — we cover this distinction in our guide to reading a gluten-free label.

A tour of Europe’s associations

Every country has its own longstanding association, and each has built its own programmes:

Association	Country	What it does
AFDIAG	France	Licenses the crossed grain for products made in France, informs and advocates for patients
AIC	Italy	Spiga Barrata logo on products, a dedicated out-of-home dining programme with staff training
FACE	Spain	Guarantee mark on tested products, a very active network of regional associations in dining
Coeliac UK	United Kingdom	Licenses the Crossed Grain and runs an accreditation programme for restaurants and catering services

The landscape moves at two speeds: everywhere, associations certify products; but support for restaurants varies enormously from one country to another. Italy and Spain stand out as pioneers — it’s no accident that eating gluten-free feels easier there than elsewhere. In France, AFDIAG plays an essential role in information and product certification, but there’s no systematic national equivalent for auditing restaurants one by one.

Product certification vs. restaurant accreditation: two different worlds

This is the most important distinction in this article.

Certifying a product means checking a stable object: a recipe, a production line, batches that can be tested in a lab. The result is binary and verifiable — under 20 mg of gluten per kilo, or not.

Accrediting a restaurant means assessing a living process: staff who change, suppliers who vary, a kitchen where every single service replays the risk of cross-contamination. A serious accreditation requires training, written procedures, and regular checks. That’s valuable — and precisely why it’s rare.

Why are so few restaurants certified?

If you go looking for an association’s logo on a restaurant’s front window, you’ll be disappointed: even in the best-organised countries, only a minority of establishments are accredited. Three reasons explain this:

• Cost. Initial audit, annual fee, lab testing, staff training time: for an artisan or a small restaurant, the bill weighs heavily against already-tight margins.
• Administrative burden. Keeping documented procedures, tracing every supplier, training every new employee: many small teams do flawless work without having the resources to get it certified.
• Geographic coverage. Accreditation programmes simply don’t exist everywhere, and where they do exist, they only cover part of the territory.

The paradoxical result: the absence of certification says almost nothing. A 100% gluten-free bakery run by a coeliac artisan can be infinitely safer than a mixed kitchen — without any logo ever signalling it.

How Nutrixe complements certification

That’s exactly the gap our work fills. Official certifications are valuable, and when an establishment holds one, our listings mention it. But waiting for a logo to appear on every good address would mean ignoring the vast majority of genuinely safe places.

Our method: verify every address at the source, one by one — the establishment’s official website, publications from coeliac associations, local press — to establish what actually matters: is the kitchen entirely dedicated? Is wheat flour handled on site? What risks remain? The result is on the Nutrixe map: a documented confidence level, even where no certification exists.

In practice, the two approaches add up: an association’s logo is an excellent signal when it’s there, and source verification picks up the slack everywhere else.
