FSMA 204 Traceability Lot Code Requirements for Food Packing Operations

Food packing companies in the United States are getting ready for big changes in food traceability under FSMA 204. The FDA’s Food Traceability Final Rule brings stricter recordkeeping rules to help improve traceability, make recalls faster, and increase supply chain visibility.

The FSMA final rule for extra traceability records applies to businesses that make, process, pack, or hold foods on the Food Traceability List (FTL). The new requirements focus on where traceability lot codes originate, maintaining accurate records, and enabling the FDA to respond faster during contamination investigations.

Companies affected by FSMA 204 need to get ready before the compliance deadline on July 20, 2028.

The FSMA 204 traceability lot code system is a key part of the regulation. Traceability Lot Codes, Critical Tracking Events, and Key Data Elements all help track food as it moves through the supply chain.
These tools help businesses and regulators find where contamination may have started.

The regulation affects food manufacturers, packers, distributors, warehouse operators, transportation providers, retailers, and technology vendors who support food traceability systems.

Businesses that still use spreadsheets, outdated ERP systems, or manual warehouse tracking may need to change how they work. Many companies are now upgrading barcode scanning systems, adopting GS1 standards, using RFID tools, updating ERP traceability software, and adding EDI integrations. These steps help improve compliance readiness.

What Is FSMA 204?

FSMA 204 is part of the Food Safety Modernization Act. The regulation establishes additional traceability recordkeeping requirements for foods considered high risk for foodborne illness outbreaks.

The FDA made this rule to make recalls more accurate, lower contamination risks, and improve visibility in the food supply chain.

The official regulation falls under 21 CFR Part 1, Subpart S, and applies to businesses that manufacture, process, pack, or hold foods listed on the FDA Food Traceability List.

The FDA wants businesses to quickly find affected products during recalls, so they do not have to remove large amounts of food that are not affected.

This means businesses need stronger lot-level traceability.

What Is the FSMA 204 Food Traceability Final Rule?

The FDA Food Traceability Final Rule sets standard traceability requirements for different points in the supply chain. Businesses covered by the rule must keep records for Critical Tracking Events and Key Data Elements.

If there is an investigation or recall, the FDA expects companies to provide traceability records within 24 hours.

The regulation strongly emphasizes supply chain compatibility. Traceability records must link suppliers, manufacturers, distributors, transportation providers, warehouses, and retail food establishments.

This is why many food businesses are switching from paper records and disconnected spreadsheets to digital food traceability systems.

What Foods Are Covered Under the Food Traceability List?

The FDA Food Traceability List includes foods associated with elevated food safety risks. Examples include:

• Fresh leafy greens
• Cucumbers
• Melons
• Nut butters
• Shell eggs
• Soft cheeses
• Finfish
• Crustaceans
• Ready-to-eat deli salads
• Fresh-cut fruits and vegetables

Requirements apply when businesses manufacture, process, pack, or hold foods on the Food Traceability List.

Some exemptions and modified requirements may apply to:

• Small farms
• Restaurants
• Certain fishing vessels
• Retail food establishments
• Direct-to-consumer operations

Businesses should check FDA guidance because requirements can change based on how food is packed, processed, shipped, or received.

Understanding FSMA 204 Traceability Lot Codes (TLCs)

A Traceability Lot Code, or TLC, is a unique code that connects traceability records throughout the food supply chain.

The traceability lot code links key data elements across critical tracking events. These codes make recalls more precise and help investigators respond faster during foodborne illness investigations.

Traceability lot codes connect records tied to:

• Harvesting
• Cooling
• Initial packing
• Shipping
• Receiving
• Transformation

Under FSMA 204, businesses must assign traceability lot codes and maintain records that identify:

• Product descriptions
• Lot identifiers
• Quantities
• Event dates
• Trading partner information
• Location description details
• Reference records

Traceability lot codes help investigators find where contamination started and track where the affected food went next.

If lot tracking is not standardized, recalls can become larger, slower, and more costly.

Critical Tracking Events (CTEs) Explained

Critical Tracking Events are supply chain activities where businesses must record traceability data under FSMA 204.

Each tracking event requires related Key Data Elements.

Additional tracking events include harvesting cooling activities, shipping, receiving, first land-based receiving, and transformation processes.

Initial Packing

Initial packing occurs when a raw agricultural commodity is first packed.

Businesses involved in initial packing must assign traceability lot codes and maintain records connected to the source, quantity, and handling process.

Foods initially packed under FSMA 204 must maintain traceability continuity as products move between suppliers, warehouses, distributors, and retail food establishments.

Transformation

Transformation occurs when food changes through manufacturing, repacking, relabeling, processing, or ingredient mixing.

Transformation creates additional traceability challenges because multiple traceability lot codes may be combined into a single finished product.

Food manufacturers must document how original traceability lots connect to newly assigned traceability lot codes.

Many ERP systems have trouble handling this kind of transformation tracking.

Shipping

Shipping events require businesses to document where products originated, where products moved, and which trading partners received shipments.

Barcode scanning systems and EDI integrations can automate much of this process.

Many food companies now use EDI 856 Advance Ship Notices to improve traceability data exchange.

Receiving

Receiving events document incoming shipments and associated traceability lot codes.

Warehouse management systems often support receiving workflows through barcode scanning, RFID readers, and automated inventory reconciliation.

If receiving records are missing, it can break traceability and lead to serious compliance risks.

Key Data Elements (KDEs) Required Under FSMA 204

Key Data Elements are the specific records businesses must maintain for each Critical Tracking Event.

Examples of key data elements (KDES) include:

• Traceability lot code
• Product description
• Quantity
• Unit of measure
• Event dates
• Shipping reference numbers
• Receiving records
• Transformation details
• Trading partner information
• Location description records

The FDA expects businesses to organize their records so they can be found quickly during recalls and investigations.

Many food companies are upgrading their systems because using disconnected databases and spreadsheets often causes data accuracy problems.

How GS1 Standards Support FSMA 204 Compliance

GS1 standards help standardize food traceability systems across the supply chain.

Businesses using GS1 barcode standards can improve product identification, shipment communication, and lot tracking between trading partners.

GS1 systems commonly support:

• GTIN product identifiers
• Serialized barcode labels
• Batch tracking
• Lot tracking
• Electronic data exchange
• Supply chain compatibility

These standards help businesses connect their ERP systems, warehouse management systems, transportation platforms, and supplier databases.

Many organizations also use GS1 standards to improve recall precision and FDA inspection readiness.

EDI 856 Advance Ship Notices and Traceability

The EDI 856 Advance Ship Notice plays an important role in digital food traceability.

An EDI 856 ASN electronically shares shipment details between trading partners before products arrive.

The notice may include:

• Product identifiers
• Shipment quantities
• Traceability lot codes
• Pallet information
• Case information
• Destination details

This improves supply chain visibility and reduces mistakes from manual data entry.

For food packing operations handling large shipment volumes, EDI automation can improve efficiency and compliance readiness.

ERP and WMS Integration for FSMA 204 Food Traceability

Many food packers already use ERP and warehouse management systems, but older systems may not fully support FSMA 204 traceability requirements.

Food companies across the United States are upgrading their ERP traceability systems, warehouse management platforms, RFID tools, and barcode scanning workflows ahead of the July 20, 2028, compliance deadline.

Businesses are evaluating whether their systems can:

• Capture KDEs automatically
• Link CTE records together
• Support lot-level traceability
• Maintain transformation records
• Generate sortable spreadsheets
• Produce rapid FDA responses
• Integrate with barcode scanners
• Support supplier compatibility

Automating warehouse processes can also make traceability more accurate.

Barcode scanning helps reduce manual entry mistakes. RFID systems make inventory easier to track. Integrated ERP traceability systems let businesses connect traceability data across different departments.

Businesses that use disconnected systems often have trouble during mock recalls because it takes too long to find records.

The FSMA 204 Traceability Plan

FSMA 204 requires covered businesses to maintain a written traceability plan.

Businesses that manufacture, process, pack, or hold foods on the Food Traceability List must document how they assign traceability lot codes, organize records, and maintain location descriptions for FDA requests.

The traceability plan should explain:

• Procedures for maintaining traceability records
• Methods for assigning traceability lot codes
• How foods on the Food Traceability List are identified
• System workflows
• Record retention procedures
• Contact information for responsible personnel

The traceability plan should also explain how records connect across critical tracking events (CTEs).

Many organizations conduct mock recalls to test whether records can be retrieved quickly and accurately.

These exercises often reveal problems involving supplier coordination, transformation tracking, and data consistency.

FSMA 204 Compliance Deadline: July 20, 2028

The FDA extended the FSMA 204 compliance deadline to July 20, 2028.

The extension gives the food industry more time to upgrade systems, coordinate with trading partners, and improve compliance readiness.

Originally, many businesses planned around the January 20, 2026, implementation timeline. The FDA later extended the deadline after recognizing that many businesses needed additional preparation time.

Even with the deadline extension, businesses should start planning now.

Upgrading ERP systems, working with suppliers, integrating WMS, and testing traceability often take a lot of time to complete.

How Food Packers Should Prepare for FSMA 204

Food packing operations should begin with a traceability gap assessment.

The assessment should identify weaknesses involving:

• Lot tracking
• Barcode labeling
• Supplier communication
• ERP workflows
• Warehouse scanning processes
• Recall documentation
• Transformation tracking
• Record retention

Businesses should also check if their current systems can create an electronic, sortable spreadsheet for quick FDA response during recalls or outbreak investigations.

After the assessment, businesses should prioritize system upgrades.

Many food companies now use cloud-based traceability platforms that connect ERP systems, WMS software, barcode scanners, and EDI networks.

Food packers should work closely with suppliers and customers because food traceability relies on consistent data exchange across the supply chain.

Training employees is also important.

Teams that handle receiving, shipping, production, labeling, and inventory management need to understand how traceability records are connected.
