A GFSI-recognized food safety scheme built for fresh produce — what the audit covers, how it is scored, and what it takes to be ready.
PrimusGFS is a food safety certification scheme written specifically for the fresh produce supply chain. It is administered by Azzule Systems and is benchmarked against the Global Food Safety Initiative, which is why a retailer asking for "a GFSI audit" will usually accept it.
The scheme is unusual in how much of the chain it covers with one standard. A single PrimusGFS audit scope can include the farm, the harvest crew, the packinghouse, cold storage and a processing facility. Most produce schemes handle one link; PrimusGFS was designed for operations that touch several.
It is built around modules. Every certified operation is audited against a food safety management system module, and then against the operational modules that match what the business physically does. A grower who also packs is audited on more than a grower who sells field-run product to someone else's packhouse.
The practical difference from a USDA Harmonized GAP audit is depth rather than subject matter. Both ask about water, worker hygiene, sanitation and traceability. PrimusGFS additionally asks you to prove you run a management system around those practices: a documented HACCP plan, internal audits, supplier approval, mock recalls, corrective actions with verified closure, and a named person accountable for each.
Nobody pursues PrimusGFS for its own sake. It shows up because a buyer's supplier requirements name it, or name GFSI recognition generally.
In practice the request comes from large retail grocery programs, foodservice distributors, fresh-cut processors who need their inbound supply certified to the same level as their own facility, and buyers moving product between the United States, Mexico and Central America, where PrimusGFS is especially common.
A retail or foodservice account whose supplier agreement requires a GFSI-benchmarked certificate rather than a GAP audit.
Operations that both farm and pack, where one audit covering field and facility is simpler than two separate certificates.
Labour contractors and harvest operations audited on their own scope because the product changes hands in the field.
Businesses shipping between the U.S., Mexico and Central America, where PrimusGFS is the most commonly named scheme.
If your buyer has not named a scheme, ask before you book anything. Switching schemes after an audit is expensive, and an audit nobody asked for is money spent on paperwork instead of a market.
The scheme is modular. Your scope determines which modules the auditor works through, and each is scored independently.
The management layer: policy, responsibilities, document control, HACCP plan, internal audits, supplier approval, traceability and recall, complaint handling and corrective actions. Required in every scope.
Field-level operations: land history and adjacent land use, agricultural water, soil amendments, worker health and hygiene, field sanitation, harvest practices and equipment.
Facility-level operations: building and grounds, sanitation programs, pest control, equipment condition, personnel practices, chemical control and maintenance.
Module applicability, numbering and the exact question sets change between versions of the standard. Confirm the current version and your scope with your certification body before preparing — Azzule publishes the active version and its checklist.
PrimusGFS is scored as a percentage per module rather than as a simple pass or fail. Findings are classified by severity, and severity matters more than the raw number of findings.
The classifications and the passing threshold are set by the standard and interpreted by your certification body, and many buyers then impose their own minimum on top. That is why two farms with the same score can get different answers from different customers.
| Finding type | What it means | Practical effect |
|---|---|---|
| Critical | An immediate food safety risk, or evidence of falsified records. | Generally halts the audit outcome regardless of the score elsewhere. Expect to correct and be re-audited. |
| Major | A required element is missing or systematically not working. | Pulls the module score down sharply and usually requires documented corrective action with evidence. |
| Minor | A requirement is met but imperfectly or inconsistently. | Costs points. A pile of minors in one area is often read as a system problem, not a set of small ones. |
The single most common cause of a disappointing score is not a dirty facility. It is records that exist but cannot be produced on request, or that were completed after the fact.
An auditor is checking whether your system ran all season, not whether it exists today. That means preparation is mostly about accumulating an honest record trail with dates on it, and only partly about writing documents.
A farm starting from nothing usually needs one full production period of real records before an audit is worth booking. A farm already running a Harmonized GAP program typically needs to add the management-system layer: the HACCP plan, internal audits, supplier approval files and a mock recall.
Agree with your certification body exactly which modules apply and which version of the standard you will be audited against.
Food safety policy, SOPs and the HACCP plan come first, because every log you keep afterwards is evidence that the plan is real.
Water tests, sanitation, training, temperature, harvest, traceability. Gaps in the log are the finding — not the activity you forgot to write down.
The scheme requires you to audit yourself and prove you can trace product both directions. Do this early enough to fix what it exposes.
Every gap you find and document with a corrective action is a gap the auditor does not have to write up.
GAP APP does not certify anyone. What it does is keep the evidence a PrimusGFS auditor asks for in one place and organized the way the standard is structured.
Process flow, hazard analysis, critical control points, limits and monitoring — the Module 1 documentation, built as a working plan rather than a one-off document.
Water, sanitation, temperature, training and harvest logs captured on a phone in the field, so records exist when they happened instead of the night before the audit.
Run a scored self-assessment, see the findings classified by severity, and fix them before someone external does the same walk.
Approved supplier files, certificates with expiry tracking and version history on every SOP.
Log a nonconformity, assign it, attach the proof it was fixed and record who verified it.
Export the whole evidence set organized by module so the auditor is not waiting on you to find things.
