A public health department identifies an increase in cases of E. coli linked to fresh-cut leafy greens. As investigators interview patients, they discover they all purchased packaged salad mixes distributed through multiple grocery chains. Using the traceability records required under FSMA Section 204, regulators and supply chain partners work to quickly identify the grower, processor, and distribution path of the affected product, allowing the recall to be limited to specific lots rather than removing all salad products from store shelves.
The longer it takes to trace the source, the longer contaminated food stays in the market. How well the manufacturer can trace the origin of the contamination can mean the difference between a broad recall that costs millions and risks consumer health, and a swift, targeted recall.
For manufacturers who handle foods on the FDA’s Food Traceability List, being inspection ready for compliance with FSMA Section 204 means being able to quickly reconstruct a product’s path through the supply chain.

What is FSMA Section 204, and Why Was It Created?
In 2011, the Food Safety Modernization Act (FSMA) was passed, creating a shift in the way manufacturers approach food safety. Rather than react to outbreaks and contamination in supply chains, FSMA places a focus on prevention.
This means that the FDA doesn’t merely expect a facility to be clean or meet labeling requirements. They expect manufacturers to understand food safety risks, enact preventive control measures, and be able to quickly respond when something does go wrong.
FSMA Section 204, known as the Food Traceability Rule, was included to improve the ability of manufacturers, suppliers, and regulators to quickly trace foods through the supply chain during food safety investigations.
Prior to the implementation of the food traceability rule, the FDA and manufacturers needed to comb through thousands of records to recreate the path that an ingredient took through the supply chain to a retailer. That process could potentially take weeks.
Now, the expanded FSMA Section 204 record keeping requirements make it much easier for the FDA and manufacturers to identify and remove potentially contaminated foods from the supply chain.
Section 204 doesn’t replace other food safety requirements like HACCP, preventive controls, or sanitation programs, but it does add an additional layer of traceability and rapid response needed to contain contamination events.
Does FSMA Section 204 Compliance Apply to Your Business?
FSMA Section 204 requirements don’t apply to every food manufacturer. The food traceability rule primarily applies to manufacturers that process, pack, or hold foods that are included on the FDA’s Food Traceability List (FTL).
So what types of foods are found on the list? The FTL includes foods that the FDA considers to be at a higher risk for foodborne illness.
- Soft cheeses
- Shell eggs
- Nut butters (such as peanut butter)
- Fresh leafy greens
- Fresh-cut fruits and vegetables
- Melons
- Tomatoes
- Peppers
- Sprouts
- Shellfish (such oysters and clams)
- Crustaceans (such as shrimp and crab)
- Ready-to-eat salads
This isn’t an exhaustive list, but rather some of the more common food items and ingredients to which FSMA Section 204’s traceability requirements may apply. An important takeaway is that whether you produce a finished product or simply provide ingredients for other manufacturers, these traceability standards could possibly apply to you.
Manufacturers and suppliers should consider seeking knowledgeable food safety compliance consulting to understand whether FSMA Section 204 requirements apply to your business.
What FDA Inspectors Are Really Looking For
Food suppliers and manufacturers need to be ready for an FDA inspection, but they’re not simply looking for paperwork. They’ll want you to prove that you can reliably trace a product’s movement throughout your supply chain.
Section 204 establishes two key concepts for manufacturers and suppliers to improve traceability consistency.
Critical Tracking Events (CTEs)
These are major events in the food supply chain that the FDA requires businesses to track. Think of major events like harvesting, cooling, initial packing, receiving, and shipping.
For example, a manufacturer may need to document when ingredients arrive at their facility, how they are used to create new products, when they are packed, and where the finished product is sent.
For foods covered by the Food Traceability List, manufacturers must maintain records associated with applicable Critical Tracking Events throughout the supply chain.
Key Data Elements (KDEs)
With every critical tracking event, key data elements are collected. KDEs are specific data points or records tied to each CTE, like product descriptions, quantities, lot codes, location information, shipping and receiving dates, and specific supplier or customer information.
These key data points help the FDA ensure they have enough information about each ingredient or product to confidently know where it came from through a supply chain.
How do CTEs and their KDEs look in action?
Let’s examine a batch of leafy greens grown by a supplier.
The grower records information about their harvest, and the greens enter the traceability system. That might include a lot code for that specific harvest, the amount of greens harvested, the date of the harvest, and even the specific farm and field that lot came from.
This is just one of many Critical Tracking Events that may be documented as the leafy greens move through the supply chain and become part of a packaged salad product.
What Records Should California Manufacturers Maintain for FSMA Section 204 Compliance?
FSMA 204 requirements are designed to create a traceable system that shows where food products originate, how they move through a supply chain, and where they ultimately end up. These requirements are less about paperwork, and more about ensuring manufacturers can rapidly identify where an affected product came from during a food safety investigation or recall.
What specific records a company needs to keep largely depends on the exact product they are producing, but there are several key areas where accurate records are most helpful.
Supplier and Receiving Records
These records document where an ingredient came from, and when they entered a facility. They often contain key information like the supplier, product descriptions, quantities received, lot codes, and receiving dates. This often creates the first official connection between an incoming ingredient and the final product.
Production and Transformation Records
Production and transformation records indicate when an ingredient was used in the creation of a product. For the leafy greens in our example, the manufacturer needs a record of which lot of greens were used to produce a specific batch of prepackaged salads. Production and transformation records can help them quickly identify which batches of greens may have been contaminated, and directly impacts which batches need to be recalled.
Shipping and Distribution Records
These records allow investigators to see exactly where each finished batch of product was delivered. If we know which specific batches of packaged salads were sent to the retailer where the outbreak was reported, it means we can work backwards to trace the ingredients all the way through the supply chain.
A common misconception is that purchasing traceability software alone is enough to reach compliance. While software can support traceability, the accuracy of the system still depends on accurate data entry, employee training, and reliable record keeping.
Manufacturers should create a documented traceability plan that explains how each of these records are collected, maintained, and retrieved. It’s not simply about the documentation, but the system that lets manufacturers and investigators reliably trace ingredients from the finished product back through the supply chain to the original source and processes.
How to Prepare for an FDA Inspection Under FSMA Section 204
If you’ve been selected for inspection under the food traceability rule, the FDA expects you to be able to demonstrate that your traceability systems work. One of the most effective ways to prepare is by conducting a mock recall exercise with support from a food safety consultant.
This often involves selecting a specific ingredient or finished product lot and testing whether your organization can actually trace it back to its suppliers, as well as forward to customers. The goal of these exercises isn’t necessarily perfection, but to identify gaps, such as missing lot codes, inconsistent documentation, or missing receiving records.
Another way a consultant can help is by reviewing how your team collects and records information. Receiving teams, production operators, and quality personnel each have an important role to play in documenting the traceability of each ingredient and product in your facility. If employees are not following documented procedures, even the strongest traceability system can fail.
While technology has a valuable place in modern manufacturing, it can’t be treated as an infallible record. An ERP or inventory management system can organize information, but if suppliers and manufacturers have poor data entry practices, those systems cannot correct missing or incomplete records. A consultant can help you make sure that the right KDEs and CTEs are recorded, making it easier to trace an ingredient.
Working with a consultant will help prepare you ahead of time by identifying gaps before an FDA inspection occurs, giving your organization a chance to correct these issues and achieve FSMA compliance for food manufacturers.
