What Is Food Traceability?
Food traceability is the ability to follow a food product and its ingredients through every stage of the supply chain. Lot codes and key details are recorded at each receipt, transformation, and shipment, so any lot can be traced back to its source and forward to every customer who received it.
How Food Traceability Works
Each business in the supply chain keeps records one step back and one step forward. Linked together, those records trace food from farm to table:
Lot Codes at Receiving
Every incoming ingredient or product is received with the supplier's lot code, date, quantity, and location.
Ingredients Linked in Production
When food is processed or repacked, the new finished lot records every ingredient lot that went into it.
Lot Codes on Every Shipment
Each order records which lots shipped, in what quantity, and to which customer and location.
Fast Lookups When It Matters
In a recall or audit, one lot code shows its supplier, what it went into, who received it, and how much is still on hand.
Food Traceability Example: A Supplier Recall
A produce distributor receives baby spinach from a grower. Four days later, the grower recalls one lot. This is how the distributor's records play out:
| Date and Time | Event | Document | Details |
|---|---|---|---|
| Sep 12, 7:40 AM | Received | PO-7735 | 120 cases, grower lot code SP-0912, stored in cooler C-2 |
| Sep 12–15 | Shipped | SO-31204, -31219, -31250 | 48 cases to 3 customers, lot code recorded on each shipment |
| Sep 16, 9:00 AM | Recall notice | Grower notice | Recall Lot SP-0912 recalled for possible contamination |
| Sep 16, 9:15 AM | Lot traced | Lot report | 48 cases at 3 customers, 72 cases still in cooler C-2 |
| Sep 16, 9:30 AM | Stock on hold | HOLD-118 | 72 cases blocked from picking and removed from available stock |
| Sep 16, 10:00 AM | Customers notified | Recall log | Only the 3 affected customers contacted, with quantities and ship dates |
Within an hour, the distributor knew exactly where all 120 cases were. Without lot codes on its shipments, it would have had to contact every customer who bought spinach that week and pull every case from the cooler, including stock from other, unaffected lots.
FSMA 204: The FDA Food Traceability Rule
Section 204 of the Food Safety Modernization Act requires businesses that manufacture, process, pack, or hold foods on the FDA's Food Traceability List to keep additional records. The FDA has extended the compliance date to July 20, 2028. The rule is built on three ideas:
Critical Tracking Events (CTEs)
The points in the supply chain where records must be kept, such as receiving, shipping, and transformation.
Key Data Elements (KDEs)
The details recorded at each event, such as the traceability lot code, quantity, date, and locations.
Traceability Plan
A written plan describing how records are kept, how lot codes are assigned, and who to contact with questions.
| Critical Tracking Event | Who Records It | Example Key Data Elements |
|---|---|---|
| Harvesting and Cooling | Farms | Commodity, quantity, date, farm location |
| Initial Packing | Packers of raw agricultural products | New traceability lot code, packing date, location |
| Shipping | Anyone shipping a listed food | Lot code, quantity, ship-to location, ship date |
| Receiving | Anyone receiving a listed food | Lot code, quantity, ship-from location, receive date |
| Transformation | Processors and manufacturers | Input lot codes, new lot code, quantity, date |
Seafood also has a "first land-based receiving" event. Records must be provided to the FDA within 24 hours of a request, and in certain situations as an electronic sortable spreadsheet. This is a summary only; check the FDA's guidance for how the rule applies to your operation.
Benefits of Food Traceability
Smaller, Faster Recalls
Only the affected lots and customers are involved, so less product is destroyed and fewer customers are disrupted.
Regulatory Readiness
Records are ready when the FDA, an auditor, or a customer asks, instead of being rebuilt from paper under deadline.
Customer and Retailer Trust
Grocery chains and foodservice buyers increasingly require traceability from their suppliers.
Better Shelf-Life Control
Lot dates support first in, first out picking, so older stock ships first and less food expires on the shelf.
How to Start Food Traceability
- 1Check the Food Traceability List. Identify which of your products and ingredients are covered by FSMA 204, and start with those.
- 2Map your tracking events. List every point where those foods are received, transformed, and shipped in your operation.
- 3Turn on lot tracking. Require a lot code on every receipt, production run, and shipment for covered items.
- 4Work with suppliers. Make sure suppliers send lot codes on packaging and shipping documents so you can record them at receiving.
- 5Write your traceability plan. Document how lot codes are assigned, where records are kept, and who is responsible.
- 6Run a mock recall. Pick a lot and time how long it takes to find its supplier, its customers, and what is left in stock. Aim for well under 24 hours.
Common Food Traceability Mistakes to Avoid
A single missing record breaks the chain.
Recording Lots Only at Receiving
If lot codes aren't captured on shipments, you know what came in but not which customers received it.
Losing Ingredient Lots in Production
If a batch doesn't record which ingredient lots it used, one bad ingredient forces a recall of everything made that day.
Keeping Records on Paper
Paper logs and spreadsheets are slow to search and hard to turn into the sortable records regulators can request.
Never Testing the System
Gaps show up during a real recall unless they are found first in a mock recall.
Who Needs Food Traceability?
Every business that handles food between the farm and the consumer plays a part in the chain:
Food & Beverage Manufacturers
Processors and co-packers that must link every ingredient lot to the finished lots it went into.
Food Distributors
Wholesalers and foodservice distributors that receive and ship covered foods every day.
Ingredient Suppliers
Producers of nut butters, cheeses, and other listed foods sold to manufacturers and retailers.
Food Banks and Meal Programs
Nonprofits that receive donated and purchased food and need to act quickly when a recall is announced.
Food Traceability in Kechie ERP
Kechie Inventory Management records lot numbers on receipts, transfers, and shipments, so every lot has a history from supplier to customer. With Kechie Manufacturing, ingredient lots are linked to the finished lots they go into. Because purchasing, production, order management, and returns share the same data, a single lot lookup shows where it came from, where it went, and what is still on hand. Data entered once is available in every relevant module in real time.
Frequently Asked Questions
What is food traceability in simple terms?
Food traceability is knowing where every lot of food came from and where it went. It lets a business quickly find which customers received a problem lot and which supplier it came from.
What is FSMA 204?
FSMA 204 is the FDA's Food Traceability Rule. It requires companies that manufacture, process, pack, or hold foods on the FDA's Food Traceability List to keep additional records, called key data elements, at specific points in the supply chain called critical tracking events.
When is the FSMA 204 compliance date?
The FDA extended the compliance date by 30 months, from January 20, 2026 to July 20, 2028.
What is the Food Traceability List?
The Food Traceability List (FTL) is the FDA's list of foods covered by FSMA 204. It includes items such as leafy greens, fresh-cut fruits and vegetables, shell eggs, soft cheeses, nut butters, and certain fish and shellfish.
What is a traceability lot code?
A traceability lot code is the identifier assigned to a lot of food when it is initially packed, received from a fishing vessel, or transformed. It must be recorded on later shipments and receipts so the lot can be followed through the supply chain.
What does one step back, one step forward mean?
It means every business can identify who it received a lot from and who it shipped that lot to. Linked together, those records trace a food through the whole supply chain.
Does every food business need to comply with FSMA 204?
The rule applies to businesses that handle foods on the Food Traceability List, with some exemptions, such as certain small farms and retail food establishments. Check the FDA's guidance to confirm how it applies to your operation.
How quickly must traceability records be provided to the FDA?
Within 24 hours of a request, or within a longer time the FDA agrees to. In certain situations, such as an outbreak investigation, records must be provided as an electronic sortable spreadsheet.
