Food traceability: why knowing your product means knowing your business

Imagine a food safety issue emerges at 10am. Leadership needs fast answers.

Which product is affected? Which lot number? Which raw materials went into it? Where was it manufactured? Which supplier provided the ingredient? Where is the remaining inventory? Which customers received it? And did the same material enter any other products?

In an urgent moment like this, food traceability stops being a theoretical principle attached to compliance. It becomes the immediate ability to reconstruct the history of a physical item – backwards to its source, and forwards through its journey to the customer.

“A recall itself does not create weaknesses in traceability. 

It reveals them.”

Food traceability: reconstructing the product journey

The European Commission describes traceability as the ability to follow food and its ingredients through production, processing and distribution. Under EU General Food Law, businesses must at minimum be able to identify their immediate supplier and immediate subsequent recipient – commonly described as “one step back, one step forward.”

But commercially useful traceability can go deeper. For a finished product, a business may need to connect a unique identifier or lot number with its: 

• Raw materials
• Source
• Manufacturing history
• Production date and time
• Location
• Quality records
• Inventory
• Onward movement

In other words, food traceability answers the question: what happened to this product, and where did it go?

A race against time

In October 2024, an outbreak of E. coli O157:H7 was linked to McDonald’s Quarter Pounders in the United States. The investigation eventually identified yellow onions supplied by Taylor Farms as the likely source. 

Taylor Farms recalled affected onions supplied to McDonald’s and other food-service customers. Major chains (including Burger King, Taco Bell, Pizza Hut and KFC) also removed onions as a precaution. McDonald’s withdrew Quarter Pounders from one-fifth of its US restaurants, and its shares fell sharply as news of the outbreak emerged.

In terms of financial and reputational consequences, McDonald’s committed more than $100 million to recovery efforts: $35 million for marketing to rebuild customer confidence, and $65 million in support for franchisees in the most heavily affected markets.

This illustrates the commercial cost of uncertainty: while the contaminated ingredient may have been relatively small, the response extended across menus, restaurants, suppliers, franchisees, customer confidence and the brand itself.

But it’s the scale here that illustrates why supply chain traceability matters.

The outbreak involved 104 reported illnesses across 14 states, 34 hospitalisations, and one death. Investigators had to work backwards from consumers and menu items towards ingredients, restaurants, distribution and suppliers. Of 81 people interviewed, 80 reported eating at McDonald’s; among those able to remember specific menu items, 84% reported eating something containing fresh slivered onions.

The commercial lesson? Once an incident occurs, specificity matters. The faster a business can identify the issue, the faster it can narrow its response.

“The value of traceability is measured when uncertainty becomes expensive.”

The architecture of a food traceability system

Good traceability connects multiple processes rather than relying on a single record.

“An unbroken chain is only as useful as its weakest handover.”

There’s an important distinction between internal traceability and supply chain traceability.

• Internal traceability follows an item through processes inside the business: receiving raw materials, food processing, manufacturing, quality control, storage and dispatch.
• Supply chain traceability connects those records across multiple companies.

Lessons from the US: could you trace it in 24 hours?

The direction of regulation is towards more granular, usable data.

The US Food and Drug Administration’s Food Traceability Rule establishes additional recordkeeping requirements for businesses that manufacture, process, pack or hold certain foods on its Food Traceability List. 

In some circumstances, covered businesses may be required to provide relevant information to the FDA within 24 hours, including an electronic sortable spreadsheet.

Enforcement of the rule has been delayed until 20 July 2028, giving industry additional time to solve the challenge of lot-level traceability across complex supply chains. But the strategic exercise is useful now: could your firm reconstruct an affected product’s journey within 24 hours?

“Knowing the data exists is not the same as being able to use it.”

Technology helps. Governance makes it work.

Modern traceability systems can connect barcodes, RFID tags, serial or lot numbers, inventory management, traceability software, mobile devices and handheld computers to capture information throughout production and logistics.

But technology itself does not equal traceability.

“Digital traceability is only as strong as the information beneath it.”

You can buy software. You cannot buy good underlying governance. If supplier information is poor, lot structures are inconsistent, processes break the chain or businesses cannot exchange usable data, digitising it simply gives you a more sophisticated version of an incomplete record.

This is reflected in the FDA approach: its rule does not prescribe a specific technology for maintaining records. Information can exist in paper or electronic form (although electronic data may be required where regulators need to trace particular products quickly).

Therefore, a commercially resilient traceability system begins with asking: 

• What needs to be identified?

• Who records it?

• Can identification survive multiple production / transformation processes?

• How will data pass between businesses?
• How quickly can the data be retrieved and the affected product located?

From product safety to commercial intelligence

Knowing the journey of a product gives you greater visibility over your suppliers, materials, inventory, quality and production.

It can strengthen quality assurance. It can support provenance and authenticity claims. It can expose recurring manufacturing problems. It can improve supplier conversations and make a product recall more targeted. And in cross-border supply chains, reliable information helps demonstrate compliance with demanding market-access requirements.

The UK’s Food Standards Agency makes the underlying economic point: the more (ideally digital) traceability information a business retains, the easier and quicker it is to identify affected food, mitigate consumer risk, and save time and money.

Consumer trust also rests upon the ability to answer questions about where food came from and what happened to it along the way.

This is why leadership teams should resist treating traceability as a database maintained for the day a regulator asks to see it. Because the real measure of traceability is how quickly that data can become an answer when something changes or goes wrong.

Speed and precision materially reduce the cost of an incident: narrowing recalls, limiting unnecessary withdrawals, supporting response, and helping protect against avoidable financial and reputational damage. Where enforcement risk exists, good traceability also provides evidence that an organisation has control over its products and supply chain.

Ultimately, knowing your product means knowing the business behind it: where its materials came from, how it was produced, where it went – and how confidently you can act when that journey comes into question.
