PDO, PGI, TSG: What EU Food Labels Actually Guarantee (And What They Don't)
You've seen the little red-and-yellow and blue-and-yellow seals on cheese, ham and olive oil. They look official — and they are. But most shoppers can't tell you the difference between a PDO and a PGI, and food marketers are very happy to keep it that way. Here is what each label legally guarantees, where the loopholes are, and how to use them to buy genuinely European food.
PDO = everything (ingredients + production) comes from one defined region. PGI = at least one production step happens in the region. TSG = traditional recipe, but it can be made anywhere. Only PDO guarantees full regional origin.
The three labels, side by side
The EU quality schemes are defined in Regulation (EU) No 1151/2012. They are not marketing badges — using them fraudulently is a crime in every member state. But they guarantee very different things:
| Label | Full name | What must happen in the region | Origin guarantee |
|---|---|---|---|
| PDO (red/yellow seal) | Protected Designation of Origin | Production, processing and preparation | Strongest |
| PGI (blue/yellow seal) | Protected Geographical Indication | At least one stage | Partial |
| TSG | Traditional Speciality Guaranteed | None — only the recipe is protected | None |
PDO: the real deal
A PDO product is inseparable from its territory. Prosciutto di San Daniele PDO can only be made in the town of San Daniele del Friuli, from pigs born and raised in a defined area of northern Italy, cured in the specific microclimate of the Friuli hills. The same logic applies to Queso Manchego, Kalamata olive oil or Comté.
When you see the red-and-yellow seal, the raw materials and the production are regional. There is no "packed in Italy from EU and non-EU pork" fine print.
PGI: read carefully
PGI only requires one production step in the named region. That's still meaningful — but it means a PGI product can use raw materials from anywhere. Some PGI hams are made from pigs raised outside the region; some PGI baked goods use imported flour. The label is honest about where it was made, not about where everything came from.
Every PDO/PGI specification is public in the EU's eAmbrosia register. Search the product name and read the "description of product" section — it states exactly what must be regional.
TSG: tradition, not territory
TSG protects a recipe, not a place. Pizza Napoletana TSG can legally be made in a factory in Poland, as long as it follows the registered method. If you're buying for origin, TSG tells you nothing.
What none of these labels cover
This is where most shoppers get caught. The EU schemes protect registered names. Everything else is open season:
- "Mediterranean style", "Greek-type yogurt", "Italian recipe" — pure marketing, zero legal meaning.
- Flags and landscapes on packaging — legal as long as the actual origin appears somewhere (often in 6-point font on the back).
- Unregistered famous names — this is the big one. Dijon mustard is not protected. Neither is Edam, Gouda (only "Gouda Holland" PGI is), or Cheddar. Anyone, anywhere can use those names. We'll dedicate a full article to the Dijon case — it's a masterclass in why name protection matters.
Some brands print circular gold seals that resemble PDO/PGI marks but say things like "Premium Quality" or "Traditional Product". Only the official EU seals — with the exact words "Protected Designation of Origin" or "Protected Geographical Indication" (or their translations) — carry legal weight.
How this feeds into the European Score
Our scoring methodology treats these labels as strong origin evidence, in this order: PDO ranks highest, PGI counts partially, and TSG adds nothing to the origin component. Combined with manufacturing location and brand ownership data, that's how a Prosciutto di San Daniele ends up scoring dramatically higher than an "Italian-style cured ham" produced who-knows-where.
A practical workflow for your next shop:
- Look for the seal first. PDO beats PGI beats nothing.
- Ignore adjectives. "Style", "type", "recipe" and "inspired" are confessions, not descriptions.
- Scan the barcode. Our scanner shows you the European Score, origin data and better-scoring alternatives in the same category in seconds.
