What Auditors Want to See Behind Your Food Safety Culture Score

A peer-reviewed systematic review published April 6, 2026 in Comprehensive Reviews in Food Science and Food Safety examined fifteen years of food safety culture questionnaires and found that none of the published assessment tools had been subjected to all of the standard validation checks that academic reviewers expect. Most relied on face validation and pilot testing alone, while the more rigorous structural methods such as confirmatory factor analysis appeared in only two of the thirty-one studies included in the review.

That gap matters now in a way it did not five years ago. SQF Edition 10 requires your facility to maintain a documented food safety culture plan with measurable performance indicators and evidence of continuous improvement, and GFSI's Position Paper on a Culture of Food Safety, Version 2.0, released March 2026, calls for measurement through multiple indicators rather than a single survey score. Auditors are starting to look past the existence of a survey and ask how the survey was built, how the items were selected, and what the numbers actually represent.

If your facility is generating culture metrics from a vendor template that has no published validation evidence, the score itself may not be the problem. The methodology behind it is.

What the research examined

Wang, Mirosa, Hou, and Bremer at the University of Otago reviewed 31 peer-reviewed studies on food safety culture measurement published between 2010 and 2025. The studies collectively surveyed more than 7,860 respondents across roughly 2,023 companies, including approximately 325 managers. European studies dominated the sample with 15 entries, followed by Brazil with 6, the United States with 4, and four cross-national projects covering multiple regions.

The pace of research has accelerated in step with regulatory expectations. Between 2010 and 2020 the literature produced 15 studies, and sixteen more have appeared since 2021, an expansion that mirrors what GFSI member schemes including SQF and BRCGS have done over the same period. Food safety culture moved from a soft commentary topic to an auditable element of the management system, and the academic instruments that operators inherited were not built for that role.

The reviewers' primary question was whether the instruments being used in the field meet basic measurement standards. They examined two dimensions: how each questionnaire defined what it was measuring, and how the instrument was tested for reliability and validity. Their conclusion is not that the instruments are useless, but that the validation evidence behind most of them is thinner than the consumers of the data assume.

The validation gap, in numbers

Across the 31 studies, the reviewers cataloged 182 distinct dimensions or sub-dimensions of food safety culture, and after clustering those reduced to eight broad groupings. The underlying point is the fragmentation: different research teams call the same construct by different names, and call different constructs by the same name, so a "leadership" dimension in one instrument is not the same as a "leadership" dimension in another.

Five dimensions appeared with consistency across the literature: Resources (in 27 studies), Commitment (26), Leadership (25), Communication (25), and Risk concepts (24). If your facility's survey covers fewer than these five core constructs, the reviewers' analysis suggests the instrument is incomplete on its face.

The validation picture is more concerning. Of the 31 studies in the review:

• 11 reported Cronbach's alpha, an internal consistency check

• 6 included expert review of items

• 5 conducted exploratory factor analysis

• 2 conducted confirmatory factor analysis

• 2 used principal components analysis

The most rigorous structural validation methods, confirmatory factor analysis and Rasch analysis, appeared either rarely or not at all across the entire sample. Twelve of the 31 studies developed new questionnaires, while the other 19 simply applied existing instruments to a new population, often without re-validating in the new context. The reviewers cite a 2024 finding from Nyarugwe and Jespersen directly: none of the assessment tools in the literature has been subjected to all of the validation checks the field considers standard, and that includes the most widely adopted instrument in the literature, De Boeck et al. (2015).

Why this matters under SQF Edition 10

SQF Code Edition 10 was released in March 2026 and formalizes food safety culture inside the management commitment element. Senior management is required to maintain a documented Food Safety Culture Plan that includes communication strategies, training programs, feedback loops, measurable performance indicators, and an evaluation system that demonstrates continuous improvement. The plan itself is not optional, and the indicators it requires are not decorative documentation.

Auditors are still calibrating how to evaluate the methodology behind culture measurement, but the practical question they now ask is consistent across audits. How did your facility choose its dimensions? What instrument did you use, and where did it come from? How did you decide that the score you reported is reliable enough to drive a corrective action?

A facility that hands the auditor a culture score without an answer to those three questions is in the same position as a facility that hands over an environmental monitoring trend chart with no swab plan behind it. The number is not the evidence. The methodology behind the number is the evidence.

GFSI's Position Paper on a Culture of Food Safety, Version 2.0, released in March 2026, pushes in the same direction. The paper calls for assessment through multiple indicators rather than a single metric and ties food safety culture to measurement, deliberate intervention, and continuous improvement of practice. The new framework drew on more than 180 academic and industry sources and replaces the original 2018 position paper that first established a common language for food safety culture across GFSI member schemes.

What an auditor looks for

The auditor's question is not whether your facility ran a survey. The question is whether the result your facility reported is defensible under examination. From the auditor's chair, a credible food safety culture measurement program shows the following five elements.

A stated theoretical framework. Your survey should be built on a defined model, whether that is the Yiannas framework, the Griffith et al. construct, the De Boeck instrument, or another published source. If the auditor asks where your dimensions came from and the answer is "the consultant who built it for us," the framework is undocumented and the program rests on assumptions the facility cannot defend.

Evidence the instrument was validated for the population using it. Validation is not a one-time event that travels with the instrument from one context to another. A questionnaire validated on European retail food service does not automatically apply to a Texas processing plant or a California co-packer, so if your facility adopted an existing tool, your records should show what was done to confirm the instrument fits the setting.

A sample design that reflects the plant population. A survey distributed only to office staff or only to leads is not measuring plant culture. The sample needs to cover production shifts, sanitation, receiving, warehouse, and maintenance, and the records should show the distribution by role and by shift.

Response rate and segmentation. A 30 percent response rate from a single shift tells you very little about your overall facility. Auditors expect to see the response rate disclosed, the results segmented by role and shift, and a written explanation when participation drops below a defensible threshold.

A closed-loop linkage between findings and corrective action. This is the element auditors weigh most heavily, because the linkage is the only thing that demonstrates the program produced an outcome rather than a record. The survey identified a weak signal on hand-washing compliance among third-shift sanitation workers. What did the facility do? What changed? When the next round measured, did the signal improve? If the answer to any of those is missing, the program is a survey, not a culture management system.

Common failures in practice

The patterns that surface most often during audits are not exotic, and they are correctable once the facility recognizes them.

The five-question quarterly survey. A short questionnaire run repeatedly with no analytical follow-through, where the numbers move quarter to quarter, no one investigates why, and the report goes into a binder. The auditor is not impressed by the cadence; the auditor wants to know what the data drove and what changed in the operation as a result.

The vendor template with no documentation. A culture survey purchased off the shelf, branded for the facility, and deployed without any record of the dimensions, the validation history, or the source. When the auditor asks for the supporting methodology, there is nothing to produce, and the conversation moves quickly toward a non-conformance.

Aggregate-only reporting. A facility-wide score of 4.2 out of 5 hides everything that matters, because culture variance lives at the shift, line, and department level, and a program that does not segment its results cannot find its weak points before the auditor finds them first.

Survey-only measurement. Questionnaires capture self-reported attitudes, but they do not capture observed behavior on the plant floor. A defensible program triangulates: the survey, the walk-through observation, and the employee interview should tell the same story, and when they do not, the discrepancy itself becomes the finding.

The missing plan-do-check-act linkage. The single most common failure across audits is the missing loop, where the facility ran the survey, recorded the score, and never returned to the same dimension to verify whether anything moved. Without a closing loop documented in the records, the survey functions as documentation theater rather than a management tool.

Building a defensible measurement program

The reviewers' practical recommendation, stated in academic terms, is to choose dimensions and items that suit the specific context being investigated. In operational terms, that translates to a small number of decisions, made deliberately and documented in the food safety culture plan itself.

Choose your framework before you choose your instrument. Decide which model your facility is using, whether that is Yiannas, Griffith, De Boeck, or another, and write down why your facility chose it. The framework drives the dimensions, and the dimensions drive the items.

Adopt a published instrument or document the gap honestly. If your facility is using a vendor tool, ask the vendor for the published validation evidence behind it, and if they cannot produce it, that is a finding waiting to happen at your next audit. The most-adopted tool in the academic literature is the De Boeck et al. (2015) instrument, with later refinements by Nyarugwe and others, and these instruments carry peer-reviewed validation history that your facility can reference in its own records.

Run validation checks that fit your scale. Most facilities will not conduct confirmatory factor analysis, and that is acceptable provided the program documents what was done in its place: pilot testing with a representative sample, expert review of items by the food safety team, internal consistency checks where the data permit, and an explicit acknowledgment of the limitations of the methodology used.

Triangulate with observation and interview. A culture program built on survey data alone is fragile, so pair the questionnaire with structured plant-floor observations on the same dimensions and short employee interviews with a representative sample. When the three sources agree, your facility has evidence; when they disagree, the discrepancy is the corrective action.

Close the loop, and document the closing. Every measurement round should produce a documented action that ties back to the next measurement, because the auditor is looking for movement in a specific dimension across two consecutive rounds, with the corrective action recorded between them. The score on its own is not enough.

What this means for your facility

The food safety culture programs that pass an Edition 10 audit are not the ones with the highest survey scores, but the ones where the documentation, the interviews, and the floor observations tell the same story, and where the methodology behind the measurement holds up to a careful question from the auditor.

If your facility is preparing for an Edition 10 transition audit and the culture measurement program rests on a survey instrument with no validation history, the gap is fixable now and will be more expensive to fix later. The first step is a written record of your framework, your instrument source, and the validation evidence you have or can obtain, and the second step is the triangulation: observation and interview alongside the questionnaire, on the same dimensions, on a defined cadence.

A practical starting point is the four-pillar plan structure covered in our food safety culture plan guide, with the methodology layer added on top. For facilities still mapping the broader Edition 10 changes, our Edition 10 preparation guide covers the structural shifts that affect documentation, monitoring, and verification across the standard.

Beacon's food safety platform builds the survey, the observation log, and the corrective action linkage into a single record so the methodology is defensible by design. For facilities preparing for an Edition 10 transition specifically, our SQF audit preparation service reviews the culture program against current auditor expectations and documents the validation gaps that need to close before the audit.

The 2026 review is not a reason to scrap your current program. It is a reason to document what your facility has, identify what is missing, and put the validation evidence in place before an auditor asks for it.
