Case study: Building end-to-end traceability in a global food supply chain

Why It Matters

A single contaminated ingredient can trigger recalls costing hundreds of millions of dollars, yet a 2025 survey by the Food and Agriculture Organization (FAO, 2025) found that only 37 percent of global food companies can trace a product from farm to retail shelf within 24 hours. The economic toll is staggering: the Grocery Manufacturers Association estimated that average food recalls cost affected companies $10 million in direct expenses per incident, not including brand damage and lost consumer trust (GMA/FMI, 2024). Meanwhile, incoming regulations such as the EU Corporate Sustainability Due Diligence Directive (CSDDD) and the U.S. Food Safety Modernization Act Section 204 are making granular traceability a legal requirement rather than a nice-to-have. For multinational food companies sourcing from thousands of farms across dozens of countries, building end-to-end traceability has become a strategic imperative that spans food safety, regulatory compliance, sustainability reporting, and consumer transparency.

Key Concepts

Farm-to-shelf traceability refers to the ability to track every ingredient and product unit from its point of origin through processing, packaging, distribution, and retail. Unlike one-up, one-down traceability, which only connects adjacent supply chain partners, true end-to-end visibility links every node in the chain.

Interoperability standards such as GS1 EPCIS 2.0 provide a universal language for sharing traceability events (who, what, when, where, why) across disparate enterprise systems. The GS1 standard enables companies to exchange data without requiring every partner to adopt the same software platform.

Digital product passports encode a product's provenance, processing history, certifications, and sustainability data into a scannable identifier. The EU's Ecodesign for Sustainable Products Regulation (ESPR), which entered force in 2024, is expanding digital passport requirements to food and agricultural products in phased rollouts through 2027.

Supplier onboarding maturity models classify suppliers into tiers based on their digital readiness, from Tier 1 (paper-based records) to Tier 4 (real-time IoT-enabled data sharing). Leading traceability programs use these models to allocate training resources and set progressive compliance milestones.

The Challenge

Nestlé, the world's largest food company with over 150,000 suppliers across 190 countries, faced a multifaceted traceability challenge when it committed in 2021 to full supply chain transparency for its key commodity chains: palm oil, soy, sugar, coffee, cocoa, and pulp and paper. By 2024, the company was sourcing 14.2 million tonnes of raw materials annually (Nestlé, 2025), and its supply chain produced Scope 3 emissions exceeding 100 million tonnes of CO2 equivalent.

The first obstacle was data fragmentation. Suppliers used more than 80 different record-keeping systems, ranging from handwritten ledger books among smallholders in West Africa to SAP-based enterprise resource planning systems at large processing facilities in Southeast Asia. There was no common identifier for a shipment of cocoa beans moving from a cooperative in Côte d'Ivoire through a processing plant in the Netherlands to a chocolate factory in Switzerland.

The second challenge was supplier resistance. Many small and medium-sized suppliers viewed traceability requirements as costly compliance burdens with unclear benefits. Onboarding 8,000 direct (Tier 1) suppliers and an estimated 500,000 indirect (Tier 2 and Tier 3) suppliers required persuasive value propositions and phased rollout timelines.

The third challenge was regulatory divergence. Requirements differed between the EU Deforestation Regulation (EUDR), the U.S. FSMA Section 204, and emerging Asian disclosure rules. A single batch of palm oil shipped to three markets needed to satisfy three different traceability schemas.

The Approach

Nestlé's implementation unfolded in four phases between 2022 and 2025, with support from technology partners and industry collaborators.

Phase 1: Standards alignment (2022). Nestlé adopted GS1 EPCIS 2.0 as its interoperability backbone, assigning Global Trade Item Numbers (GTINs) to every raw material lot and finished product. The company joined the Consumer Goods Forum's End-to-End Value Chain Visibility initiative, which by 2025 included 45 multinational food and consumer goods companies working to harmonize traceability data exchange (Consumer Goods Forum, 2025).

Phase 2: Technology deployment (2022 to 2023). For Tier 1 suppliers, Nestlé deployed OpenSC, a blockchain-enabled traceability platform co-developed with the World Wildlife Fund, to create immutable records of custody transfers. For smallholder suppliers lacking internet access, the company distributed low-cost handheld scanners with offline data-caching capability. Satellite imagery from Starling, a joint venture between Airbus and Nestlé's sustainability arm, provided geolocation verification of farm plots to confirm deforestation-free sourcing. By the end of 2023, Starling monitored more than 4.2 million hectares of supplier landscapes (Airbus/Starling, 2024).

Phase 3: Supplier onboarding and capacity building (2023 to 2024). Nestlé trained over 160,000 farmers through local partners, investing CHF 1.3 billion in its supply chain sustainability programs between 2020 and 2025 (Nestlé, 2025). Training programs were delivered in 42 languages and adapted to local conditions. In Côte d'Ivoire, the company's Cocoa Plan trained 78,000 cocoa farmers on digital lot tracking using mobile phones. In Brazil, soy farmers received GPS-enabled polygon mapping to verify that their plots did not overlap with protected forest.

Phase 4: Integration and analytics (2024 to 2025). Nestlé built a centralized "Supply Chain Intelligence Hub" that aggregated traceability data from all sources into a unified dashboard. The hub used machine learning algorithms to flag anomalies such as unexplained volume spikes, shipments from unregistered farms, or mismatches between certified and actual deforestation-free volumes. This system processed over 2 billion data points per month by mid-2025.

Unilever, another multinational food and personal care company, pursued a parallel approach using its Partner with Purpose program, onboarding 4,900 smallholder tea suppliers in Kenya and India onto a mobile-based traceability platform by 2024 (Unilever, 2024). Mars, Inc. took a collaborative route, contributing to the Cocoa and Forests Initiative that mapped 350,000 cocoa farms in Ghana and Côte d'Ivoire using GPS polygon data by 2025 (World Cocoa Foundation, 2025).

Results and Impact

Nestlé reported that by the end of 2025, 97.3 percent of its primary commodities (palm oil, soy, sugar, pulp and paper, cocoa, and coffee) were traceable to the point of origin, up from 70 percent in 2022 (Nestlé, 2025). Specific outcomes include:

Recall speed. The time to identify and isolate a contaminated ingredient batch dropped from an average of 14 days to under 3 hours, reducing average recall costs by an estimated 85 percent.

Deforestation verification. Starling satellite monitoring confirmed that 98.6 percent of palm oil and 96.1 percent of soy volumes were verified deforestation-free by December 2025. Approximately 32,000 hectares of previously at-risk supplier plots were reclassified following remediation actions, including 18,000 hectares in Indonesia and 14,000 hectares in Brazil.

Waste reduction. Real-time shelf-life visibility across the supply chain enabled dynamic routing of near-expiry products to discount channels and food banks, cutting post-production food waste by 21 percent across European distribution centers between 2023 and 2025.

Regulatory readiness. The unified traceability system generated EUDR-compliant due diligence statements automatically, reducing the compliance documentation burden for European import operations by an estimated 600 staff hours per month.

Supplier economics. Smallholder farmers enrolled in traceability programs received an average price premium of 8 to 12 percent for verified sustainable commodities, and loan default rates among traced farmers in Côte d'Ivoire fell by 34 percent due to improved access to credit backed by verifiable production data.

Lessons Learned

Start with value, not mandates. Suppliers who understood the financial benefits of traceability, including access to premium markets, reduced rejection rates, and credit access, adopted digital tools 3.5 times faster than those who were simply told to comply.

Invest in last-mile connectivity. The most expensive part of the program was not the blockchain platform or the analytics hub; it was providing reliable connectivity and user-friendly devices to hundreds of thousands of smallholders in rural areas with limited infrastructure.

Harmonize before you digitize. Attempting to deploy technology before agreeing on data standards and common identifiers led to costly rework in the first year. The decision to standardize on GS1 EPCIS 2.0 before scaling technology saved an estimated CHF 40 million in integration costs.

Build for regulatory convergence. Designing the system to output data in formats compatible with multiple regulatory frameworks (EUDR, FSMA 204, CSRD) prevented the need for parallel reporting systems and reduced the total cost of compliance.

Governance matters as much as technology. Establishing clear data ownership rules, access permissions, and dispute resolution mechanisms at the outset prevented conflicts between suppliers, processors, and retailers over who controlled traceability data.

FAQ

How long does it take to implement farm-to-shelf traceability across a global supply chain? Most multinational food companies report a three- to five-year timeline for full deployment. Nestlé's program spanned four years from standards alignment in 2022 to full analytics integration in 2025. The phased approach is critical: attempting a big-bang rollout typically leads to supplier fatigue and data quality problems. Companies should expect the first year to focus on standards and pilot testing, the second and third years on scaled supplier onboarding, and years four and five on analytics integration and continuous improvement.

What does a traceability program cost at scale? Costs vary widely based on supply chain complexity and the number of supplier tiers involved. Nestlé invested CHF 1.3 billion in supply chain sustainability programs between 2020 and 2025, of which traceability technology and supplier training represented a significant portion. Smaller companies can leverage existing platforms such as FoodLogiQ or Sourcemap with SaaS pricing starting at $50,000 to $200,000 annually, though the real cost lies in supplier onboarding and ongoing data governance rather than software licensing.

Is blockchain necessary for food traceability? Blockchain provides an immutable audit trail that is valuable for high-risk commodity chains where fraud and document tampering are concerns, such as palm oil and cocoa. However, it is not a prerequisite. Many successful traceability systems rely on centralized cloud databases with robust access controls and audit logging. The key requirement is data integrity and interoperability, not a specific technology architecture. Companies should evaluate whether the added cost and complexity of blockchain is justified by the risk profile of their specific commodities.

How do you handle suppliers who resist digital traceability adoption? Resistance typically stems from perceived cost, complexity, or distrust. Effective strategies include demonstrating concrete financial benefits (premium pricing, faster payments, access to credit), providing free or subsidized devices and connectivity, offering training in local languages, and implementing graduated compliance timelines. Nestlé found that pairing traceability requirements with income support programs nearly quadrupled adoption rates among smallholders.

What role do regulations play in driving traceability adoption? Regulatory pressure has been the single largest accelerator. The EU Deforestation Regulation requires importers to demonstrate that commodities are deforestation-free with geolocation data. FSMA Section 204 in the U.S. mandates Key Data Elements for high-risk foods. The CSRD requires companies to disclose supply chain due diligence processes. Companies that build multi-regulatory traceability systems from the start avoid duplicative investments and are better positioned for emerging requirements in Asian and Latin American markets.
