Food safety, connected: protecting producers in a digital world

Food and beverage production has become highly digitized. Automation, connected sensors, and data-driven quality assurance programmes now underpin every system, from processing and packaging to traceability and compliance. This has helped producers move faster and boosted visibility across increasingly complex supply chains.

But this new digital context has also changed the meaning of food safety.

As production becomes more connected, cyber hygiene has become just as important as physical hygiene. Even the smallest digital vulnerability could offer a point of entry for a tampering visitor, meaning food safety depends not only on clean hands and equipment, but on secure networks, protected data, and resilient operational technology (OT).

Critical control points (CCPs) sit at the center of this risk. A small, unnoticed change to cooking or pasteurisation settings could allow unsafe food to reach the supply chain and trigger a serious regulatory breach. A malfunctioning metal detector, a pH regulator that provides incorrect readings, or false negatives in ingredient testing would have similar consequences.

Every data dependency also adds a potential point of exposure. Traceability platforms, supplier records, and quality logs are essential for compliance. Networks are central to maintaining proper monitoring of production lines. Any disruption on either front can leave operators essentially blind. Every system, if compromised, threatens to impact production safety and business continuity directly.

Real breaches, real consequences

Recent cybersecurity assessments across food manufacturing sites highlight how real these risks can be. Outdated firmware on industrial controllers. Unsecured remote access systems. Weak segmentation between corporate IT and production networks. The perfect environment for attackers to gain access, move laterally between systems, and interfere with production environments.

The food sector is part of the critical infrastructure landscape. Attackers understand the leverage they gain by disrupting essential supply chains. Large, multi-site producers are particularly exposed, as downtime directly affects revenue and erodes customer trust. High-profile incidents in recent years, such as the 2025 cyberattacks on both Asahi and United National Foods Inc., have demonstrated that cyberattacks can affect production, distribution, and third-party relationships with retailers and beyond.

Not all cyber incidents are obvious. Many go unnoticed until it is too late, because they create data gaps rather than causing dramatic operational failures. But a system that silently stops recording, or logs that appear intact but are untrustworthy, is arguably more dangerous: quiet failures can persist, and they undermine the verification process that inspectors, auditors, and regulators depend on.

Looking at safety in a different way

Combatting these risks while meeting the monitoring requirements of frameworks such as HARPC and the Food Safety Modernization Act requires a cultural shift that begins with accepting that cybersecurity is a shared, cross-functional responsibility. Quality assurance, engineering, production, and IT teams all play a role.

Education and continuous vigilance are vital to ensure the kind of joined-up thinking that considers not only the systems at risk but the way they interact up and down the chain. Routine verification is vital. Just as hygiene audits ensure physical safety, regular cybersecurity assessments should test the limits of network segmentation, access controls, and incident readiness.

Hazard analysis and preventive control plans must cover both the digital domain and traditional physical and biological risks. Hazard analysis of cyber threats must be written directly into food safety programmes and incorporated into all preventative controls. Like food safety, cyber safety must be addressed proactively, not reactively.

Building strength through security

Embedding cyber resilience into food safety culture positions food and drink producers to protect their products, customers, and reputations for the long term. Those who delay risk discovering too late that their biggest vulnerability isn’t on the production line, in the supply chain, or in the ingredients, but deep within their digital backbone.

The food chain is only as strong as its weakest link. In a world where threats evolve as rapidly as technology itself, safety demands robust cyber hygiene. It is as essential to modern food production as stainless steel and sanitation schedules.
