Food safety data sharing faces trust barrier

Cornell University research has identified trust, incompatible information systems, and concerns about commercial exposure as significant barriers to pooling confidential food safety data for artificial intelligence and predictive analysis.

The qualitative study is based on interviews with 27 food industry executives, food safety directors, and managers representing dairy, meat, produce, food manufacturing, and food safety laboratory organisations.

Participants generally recognised potential benefits from combining information across companies. Larger datasets could make it easier to identify patterns that rarely appear within one business, improve predictive models, and increase understanding of uncommon food safety events.

The underlying problem is statistical as much as technological. Serious contamination incidents should be comparatively rare within a well-controlled food business, which means any individual manufacturer may have too few examples to train or test a predictive system effectively.

Pooling records from several organisations could provide a richer evidence base. Environmental monitoring results, deviations, corrective actions, complaints, process conditions, inspection findings, and near misses can all contain signals that become easier to detect when viewed across a larger population.

Smaller manufacturers could benefit particularly if a shared system gave them access to analytical capability that would otherwise require substantial investment in software, data expertise, and internal research. The Cornell interviews suggest industry participants can see that potential.

The difficulty is deciding what happens once confidential information leaves the company that generated it. Interviewees raised concerns about legal liability, regulatory scrutiny, competitive disadvantage, information being taken out of context, and loss of control over subsequent use.

Those concerns create an uneven risk equation. The benefits of better hazard detection could be distributed across the industry, while the consequences of releasing sensitive production information may fall on the individual company providing it.

Food safety records can reveal more than whether a test was positive or negative. They may expose information about suppliers, production volumes, equipment, recurring process weaknesses, sanitation performance, complaint patterns, factory layouts, or the effectiveness of internal controls.

Removing the company name does not necessarily solve that problem. A combination of product type, process, geography, plant characteristics, and event timing can sometimes make a supposedly anonymous record identifiable, particularly in specialised sectors containing relatively few manufacturers.

Technical fragmentation adds another obstacle. Participants described inconsistent record keeping, incompatible systems, and uneven levels of digital maturity. Large manufacturers may use integrated data platforms, while smaller organisations can still depend heavily on spreadsheets or paper records.

Artificial intelligence does not make those differences disappear. A larger dataset is useful only when records are defined consistently enough for the system to distinguish comparable events. If businesses use different terminology, coding structures, units, or definitions for similar food safety incidents, combining the records can increase ambiguity rather than insight.

Common data standards therefore become a prerequisite for meaningful collaboration. Participants need agreement on what information is being shared, how fields are defined, how records are anonymised, who can access them, how long they are retained, and which uses are permitted.

The interviewees identified neutral third parties, including universities, as one possible mechanism for managing those arrangements. An independent intermediary could establish access controls, provide governance, and separate commercial competitors from direct possession of each other’s underlying records.

That approach would still require clear rules around regulatory access. Manufacturers already have defined legal obligations to report particular incidents, but a voluntary shared dataset designed for research or predictive analysis serves a different purpose. Businesses are unlikely to provide detailed near-miss information if participation creates uncertain additional enforcement exposure.

The research therefore places data governance ahead of the more fashionable discussion about model sophistication. Better algorithms cannot compensate for manufacturers declining to contribute the information on which those algorithms depend.

The findings also need to be interpreted within the limits of the study. Twenty-seven interviews can provide detailed evidence about how participating professionals understand the problem, but they do not establish the proportion of food manufacturers across the wider industry that would support or reject a particular data-sharing framework.

For individual processors, the work still has an immediate implication. Consistent terminology, structured records, reliable digital capture, and traceable corrective actions improve the usefulness of food safety information inside the factory even before sector-wide data sharing becomes realistic.

Those foundations would also make controlled collaboration easier if an acceptable governance structure emerges. Without them, food manufacturers could eventually agree to share data only to discover that much of it cannot be compared reliably.

The food sector may already hold much of the information required to identify hazards earlier. The difficult part is creating technical and governance arrangements strong enough for companies to contribute that information without turning a collective food safety benefit into an individual commercial or regulatory risk.
