PDO Guijuelo — audit day arrives with the dossier already done, not with the plant queuing up to build it.
PDO Guijuelo demands traceable evidence at five stages — bellota, salting, curing, sealing and cellar — and today each stage lives in a different system that gets rebuilt by hand whenever the Regulatory Council calls. iLEAN Tracer (Connect + Agents + Edge) builds the file while the piece cures, keeps it permanently ready and verifiable, and leaves the quality team signing — not transcribing tally sheets.
Five stages, five systems, one signature — and everything done by hand when the Regulatory Council shows up.
PDO Guijuelo is built on an evidence chain that has to be complete. Today, in most plants, that chain looks like this:
- Origin of the pig and feeding regime — in the Regulatory Council's database and on delivery notes from the stockman.
- Slaughter and cutting — in the slaughterhouse's system.
- Salting and post-salting — in the chamber SCADA, with the temperature and salt curve.
- Curing and maturation — in the veteran cellarman's tally sheets, handwritten notes and the odd thermo-hygrometer reading.
- Sealing and labeling — in the ERP, linked to the batch.
When the Regulatory Council announces a visit, the quality team rebuilds the dossier by hand: exporting from SCADA, transcribing the cellarman's tally sheet, cross-referencing the ERP, hunting down the breed certificate. The result: weeks of work, a dossier that is never up to date, and the risk that a link in the chain is missing for exactly the piece the auditor asks about. The most valuable knowledge of all — the veteran cellarman's eye — is almost never digitized. The day he retires, half the cellar goes with him.
iLEAN Tracer does not replace the Regulatory Council — it seals the crack between the five systems you already have.
The PDO compliance problem is not a lack of information: every stage generates data. The problem is that the data lives in islands and only gets assembled by hand when somebody asks. iLEAN Tracer acts as the putty that fills those gaps, without asking you to change the chamber SCADA, the ERP or the Council's system.
Connect listens to every stage wherever it lives. Edge reads the chip and the seal. The agents cross-reference the PDO rules and build the per-piece dossier continuously. The person signs — never the other way round.
The iLEAN pieces applied to PDO Guijuelo:
- Connect — captures the Council's breed certificate, the stockman's delivery note, the curve from the salting chamber SCADA, the cellar thermo-hygrometer readings, the cellarman's notes (a photo of the notebook, voice dictation, a tablet app) and the sealing stamp from the ERP. Looking outward, it captures supplier emails and messages from the Regulatory Council at second zero.
- Edge — a terminal with vision and RFID/QR reading in the cellar and at the sealing station. It reads the ham's chip, links the piece to its history, photographs the piece when it is hung and when it is sealed, and drops photo + reading into the dossier without anyone copying a number.
- Agents — cross-reference the captured data with the PDO Guijuelo specification. If a link in the chain is missing (a breed certificate with no salting curve, a seal with no cellar photo, a cellarman's note with no chamber reading), they raise the flag before the dossier goes out. They build the file per piece and per batch, continuously, always ready.
A dossier rebuilt by hand vs. a continuous file with iLEAN Tracer
| Aspect | Classic PDO compliance | With iLEAN Tracer |
|---|---|---|
| Building the dossier | By hand, once the audit is announced | Continuously, while the piece cures |
| Quality team hours per audit | Weeks (export, transcribe, cross-reference) | Hours (review and sign) |
| The veteran cellarman's knowledge | In his notebook and in his head | Captured and linked to the piece |
| Spotting a broken link in the chain | The auditor finds it | The agent raises it beforehand |
| Traceability per individual piece | By batch, aggregated | By chip + photo + seal, individual |
| Response to the Regulatory Council | Reactive, on a tight margin | Proactive, with the dossier already done |
Impact estimate for your plant — to be validated with your numbers.
The block below is an estimate to be validated with the specific data of your plant. We put it forward so the committee has an order of magnitude; we refine it during the diagnostic.
- A PDO Guijuelo plant with a natural drying room and a climate-controlled cellar, x pieces/year under PDO, and a quality team spending a significant share of its time on audits for the Regulatory Council and for premium retailers.
- Tracer pilot with Connect on the salting SCADA and on the cellarman's tally sheets + a couple of Edge devices (chip and seal) + agents that build the per-piece dossier. First value within a few weeks: a pilot batch comes out with a complete, automatic file.
- Expected reduction in quality-team hours per audit above 30% against the baseline — the lever is a team that stops transcribing and goes back to doing real quality work.
- Indicative payback between 4 and 9 months, depending on PDO volume per year and the time currently spent on compliance.
- Extra lever (not monetizable in the short term): the veteran cellarman's eye is captured as a permanent capability — the day he retires, his judgement stays in the plant.
And the CAIO's reasonable doubt
“What if the AI invents evidence that is not there?” — hallucination is a problem of free generation, not of anchored tasks. iLEAN Tracer does not generate content: it recontextualizes real data (the SCADA curve, the photo of the seal, the chip reading) into the format the PDO specification asks for. In tasks anchored to the source, the best models brought error below 1.5% [1]. And even so, what is critical is never decided alone: the agent raises the flag and the person signs. The three safety rings exist precisely for this.

What people ask about AI-driven PDO Guijuelo compliance
What does PDO Guijuelo require at each stage of the ham process?
PDO Guijuelo, run by its Regulatory Council, requires traceable evidence at five stages: (1) origin of the pig and feeding regime (bellota, cebo de campo, cebo) with breed certification; (2) slaughter and cutting at an authorized slaughterhouse; (3) salting and post-salting with a controlled curve in the chamber; (4) curing and maturation in natural or climate-controlled cellars inside the geographic area of Guijuelo (Salamanca); (5) sealing and labeling with the Council's stamp, linked to the batch and to the piece. Every stage leaves a record, and a broken chain means a piece outside the PDO.
Why does a PDO audit usually arrive late and with incomplete dossiers?
Because the five stages live in different systems — the breed record in the Council's database, slaughter in the slaughterhouse's system, the salting curve in the chamber SCADA, cellar control in the veteran cellarman's tally sheets, the seal in the ERP. Pulling it all together after the fact for a Regulatory Council audit is rebuilding a jigsaw with the pieces in five different drawers — and the most valuable data of all, the cellarman's eye, is almost never digitized. iLEAN Tracer builds the dossier while the piece cures, not afterwards.
What is iLEAN Tracer and how does it apply to PDO Guijuelo?
iLEAN Tracer is the combination of Connect + Agents + Edge dedicated to building and maintaining the evidence file per batch and per piece. For PDO Guijuelo: Connect captures the origin record, the salting curve, chamber and cellar readings, the cellarman's reports and the sealing stamp. Edge reads the ham's chip, the label and the piece itself by vision. The agents cross-reference everything with the Regulatory Council's rules and, if evidence is missing for a piece, they raise the flag before the dossier goes to audit.
Does iLEAN Tracer replace the Regulatory Council or the PDO auditors?
No. iLEAN Tracer assists the plant's quality team and the Regulatory Council: it prepares the per-piece evidence dossier, keeps it permanently ready and verifiable, and cuts audit time from weeks to hours. The Regulatory Council remains the certifying authority; iLEAN makes sure the evidence is complete, ordered and traceable when they come to verify. The banner is assist and simplify, not replace.
How much does it cost and when do you see the first saving?
A typical iLEAN Tracer pilot in a PDO Guijuelo plant covers Connect (capturing chamber, cellar and sealing history), a couple of Edge devices (reading the chip and the stamp) and the agents that build the dossier — plus an annual license. First value shows up within a few weeks: the dossier for a pilot batch comes out complete automatically and the auditor reviews it in hours instead of days. Indicative payback between 4 and 9 months, depending on the volume of PDO pieces per year and the current cost of the team dedicated to collecting evidence.
