FSMA Rule 204 Traceability
Enhanced Recordkeeping for Certain Foods: Understanding the operational reality of FDA's traceability requirements for food manufacturers, distributors, retailers, and foodservice operators.
Executive Summary
FSMA Rule 204 fundamentally changes how food companies must approach traceability. Officially titled Enhanced Recordkeeping for Certain Foods, the rule requires covered entities to maintain & produce standardized, linkable traceability records that enable FDA to rapidly track foods forward & backward through the supply chain during a food safety event.
While often described as a "recordkeeping rule," FSMA Rule 204 is, in practice, an operational traceability requirement. Compliance depends not only on retaining data, but on how traceability lot codes are created, handed off, and associated with key data elements at each critical tracking event. For many companies, this exposes long-standing gaps between systems, processes, suppliers, and real-world operations.
MDB works with food manufacturers, distributors, retailers, and foodservice operators to interpret FSMA Rule 204 requirements, design practical traceability architectures, & operationalize compliance without over-engineering. Our approach is technology-agnostic, regulation-first, & grounded in real implementation experience across complex, multi-party supply chains—including environments such as airline catering where traceability execution is uniquely constrained.
What Is FSMA Rule 204 and Who Does It Apply To?
What Is FSMA Rule 204?
FSMA Rule 204 is a U.S. Food and Drug Administration regulation requiring enhanced traceability records for foods on the Food Traceability List (FTL). Its purpose is to enable faster, more precise traceback during foodborne illness investigations and recalls, reducing public health risk while limiting unnecessary product disruption.
Critical Tracking Events (CTEs)

Who Must Comply?
FSMA Rule 204 applies to most entities that manufacture, process, pack, or hold foods on the FTL, or receive, transform, or ship covered foods in the U.S. This includes:
Important: Certain exemptions and modified requirements exist, but they are narrow and activity-specific, not blanket exclusions. Many organizations initially assume they are exempt, only to discover later that specific handling, transformation, or labeling activities bring them squarely within scope.
FSMA Rule 204 does not prescribe specific technologies, software platforms, or data carriers. Companies are responsible for designing traceability systems that meet the rule's intent and performance expectations within their operational realities.

Core FSMA Rule 204 Traceability Requirements
Traceability Lot Codes (TLCs)
The Traceability Lot Code is the backbone of FSMA Rule 204 compliance. It is the identifier that links records across internal systems, trading partners, and physical product movement.
In real operations, traceability failures most often stem not from missing data fields, but from broken lot lineage caused by inconsistent labeling, aggregation, or system handoffs.
Key Data Elements (KDEs)
FSMA Rule 204 requires specific data to be captured at defined Critical Tracking Events, including Receiving, Shipping, Transformation, and Harvesting (where applicable).
Many companies discover that KDEs technically exist within their systems-but not in a way that supports rapid, defensible traceability reconstruction.
Electronic Sortable Spreadsheet (ESS)
The Electronic Sortable Spreadsheet is the FDA's practical enforcement mechanism for FSMA Rule 204. Upon request, companies must be able to produce a sortable electronic file that reconstructs the movement and transformation of a traceability lot through their operations and trading partners.
In practice, the ESS is where many "compliant on paper" programs fail. Designing for ESS readiness early is essential to reducing regulatory risk and operational disruption.

Why FSMA Rule 204 Is Operationally Hard
FSMA Rule 204 challenges organizations because it sits at the intersection of regulation, data, and real-world operations. Unlike traditional food safety programs, traceability cannot be managed by a single department or system.
In some environments—such as distribution centers, commissaries, and airline catering operations—blanket scanning or labeling mandates are operationally impractical. Companies must make deliberate, risk-based decisions about where traceability controls deliver the most regulatory value.
MDB Perspective: Successful FSMA Rule 204 programs are built by acknowledging these constraints, not ignoring them. The goal is not theoretical perfection, but defensible, scalable traceability that works under pressure—including during an FDA request or recall scenario.
FSMA Rule 204 by Supply Chain Role
FSMA Rule 204 applies across the food supply chain, but compliance looks very different depending on where an organization sits operationally. While the regulatory requirements are standardized, execution must reflect the realities of each role's handling, transformation, and data maturity.
Understanding these differences is essential to building traceability programs that are both compliant and workable.
Manufacturers and processors play a disproportionately important role in FSMA Rule 204 compliance because this is often where traceability lot codes are created, transformed, or fundamentally altered.
From a system & cost perspective, traceability is most efficiently implemented upstream. When manufacturers lead on accurate lot identification & labeling, the compliance burden for distributors, retailers, & foodservice operators is significantly reduced.
Distributors and wholesalers face FSMA Rule 204 challenges driven by volume, velocity, and variability.
In practice, many distributors adopt risk-based traceability strategies, combining selective scanning, supplier performance requirements, and process controls rather than attempting blanket, item-level intervention. FSMA compliance in distribution environments depends heavily on upstream execution and clear internal rules for exception handling.
Retailers are often closest to the consumer—and to regulatory scrutiny—but have limited ability to influence upstream data quality in real time.
Retail success under FSMA Rule 204 is less about perfect data capture and more about defensible, repeatable processes supported by supplier accountability.
Foodservice operators—including airline catering, commissaries, contract feeders, and other non-retail foodservice providers—operate in some of the most complex FSMA Rule 204 environments.
While airline catering presents unique aviation and security constraints, many of the same traceability challenges apply to foodservice operations that do not serve airlines.
Successful programs recognize that foodservice traceability is fundamentally process-driven, supported by systems—not the other way around.
A Common Thread Across All Roles:
Across manufacturers, distributors, retailers, and foodservice operators, one pattern is consistent:
FSMA Rule 204 compliance improves dramatically when traceability responsibilities are clearly owned, realistically scoped, and aligned to actual operations.
Organizations that attempt to force uniform solutions across very different roles often incur unnecessary cost, disruption, and risk—without improving recall readiness.
Common FSMA Rule 204 Implementation Mistakes
Despite good intentions, many FSMA Rule 204 traceability programs fall short—not because companies ignore the rule, but because they misunderstand how compliance actually works in practice. The following mistakes appear consistently across food manufacturers, distributors, retailers, and foodservice operators.
Treating FSMA Rule 204 as a Pure Recordkeeping Exercise
FSMA Rule 204 is often framed as a documentation requirement. In reality, it is an operational traceability mandate. Companies that focus only on storing KDEs without addressing how traceability lot codes are created, preserved, and handed off discover too late that their records cannot be reliably reconstructed during an FDA request.
Effective compliance requires aligning process design, data capture, and physical product flow—not just record retention.
Over-Relying on Software Promises
Many organizations assume that purchasing or upgrading a traceability or ERP solution automatically delivers FSMA compliance. While software is necessary, it is rarely sufficient on its own.
FSMA Rule 204 compliance is determined by outcomes, not system features. If a system cannot produce an accurate Electronic Sortable Spreadsheet on demand, it is not recall-ready—regardless of vendor claims.
Ignoring Traceability Lot Code Discipline Upstream
Traceability failures frequently originate upstream, where lot codes are created or assigned. Inconsistent lot creation rules, ad-hoc aggregation, or unclear transformation logic propagate downstream and become exponentially harder to correct.
Downstream partners—distributors, retailers, and foodservice operators—often absorb the operational and compliance burden of upstream lot inconsistencies. Strong FSMA programs establish clear lot governance early, reducing cost and risk across the network.
Designing for Audits Instead of Recalls
Some traceability programs are optimized to "look compliant" rather than to function during a real event.
FSMA Rule 204 is tested during recalls and investigations, not audits. Designing traceability to work during time-compressed, high-stress scenarios is far more important than producing perfect diagrams or policy documents.
Assuming Universal Scanning Is the Answer
Scanning can be an important traceability enabler—but it is not a universal solution. Mandating scanning at every handoff without considering labor, space, throughput, and exception handling often leads to:
Effective FSMA programs apply risk-based scanning strategies, focusing on points of highest traceability value rather than indiscriminate data capture.
Underestimating Supplier Readiness and Variability
FSMA Rule 204 compliance extends beyond internal operations. Many organizations underestimate the time and effort required to align suppliers on lot labeling expectations, KDE definitions, and data formats and timeliness.
Without structured supplier onboarding and performance management, traceability programs stall or shift into perpetual exception mode. Early engagement and clear expectations are essential to scalable compliance.
Waiting Too Long to Test ESS Readiness
The Electronic Sortable Spreadsheet is often treated as a future deliverable—something to address closer to enforcement. This is a costly mistake.
Organizations that test ESS generation early can correct issues incrementally. Those that wait often face compressed remediation timelines, higher cost, and increased regulatory risk.

A Practical Perspective
The most successful FSMA Rule 204 programs are not the most complex. They are the ones that:
Avoiding these common mistakes significantly reduces both compliance risk and unnecessary disruption—while building traceability capabilities that deliver value beyond regulation.
