FSMA 204 in plain English for small food companies

, 7 minute read

The FDA Food Traceability Rule, usually called FSMA 204, is the part of the Food Safety Modernization Act that deals with tracing food through the supply chain. Its goal is simple: when people get sick, FDA wants to find the source and pull the right products in days, not weeks.

For a small food business, the rule can read like it was written for someone with a compliance department. This guide translates it.

The compliance date

The original compliance date was January 20, 2026. It has since moved to July 20, 2028. That sounds far away, but retailers have not waited. Several large buyers already ask suppliers for the same data on their shipments, and the setup work takes longer than most teams expect.

Does it apply to you?

The rule applies if you manufacture, process, pack or hold foods that appear on FDA’s Food Traceability List. The list includes:

  • Soft and semi-soft cheeses, shell eggs and nut butters
  • Fresh cucumbers, herbs, leafy greens, melons, peppers, sprouts, tomatoes and tropical tree fruits
  • Fresh-cut fruits and vegetables
  • Finfish, crustaceans and molluscan shellfish
  • Ready-to-eat deli salads

It also applies to foods that contain a listed food as an ingredient, as long as that ingredient stays in the same form. A salad kit with fresh-cut lettuce is covered. A cooked soup made from those greens is generally not.

There are full and partial exemptions, including for some small farms and small retail food establishments. Check FDA’s exemptions guidance before assuming you are in or out.

The three ideas that make the rule work

Critical tracking events

A critical tracking event (CTE) is a moment in the supply chain where food changes hands or changes form. The rule names them:

  • Harvesting
  • Cooling, before initial packing
  • Initial packing of raw agricultural commodities
  • First land-based receiving, for seafood
  • Shipping
  • Receiving
  • Transformation, such as cutting, mixing or relabeling

You only keep records for the events you actually perform. A distributor mostly deals with receiving and shipping. A fresh-cut processor handles receiving, transformation and shipping.

Key data elements

For each event, you record specific key data elements (KDEs). Most include the traceability lot code, the product description, the quantity and unit of measure, the location of the event, the date, and the business you received from or shipped to. The exact list depends on the event.

Traceability lot codes

A traceability lot code (TLC) is the code that identifies a lot. It is assigned when food is initially packed, first received from a fishing vessel, or transformed. Everyone downstream records that same code instead of inventing their own. That single rule is what lets FDA follow one lot of romaine from a field to a store shelf.

The two documents FDA can ask for

  1. A written traceability plan. It describes how you keep records, how you identify listed foods, how you assign lot codes, and who to contact. Farms that grow or raise listed foods also include a farm map.
  2. Your records, within 24 hours. When FDA requests them, you have 24 hours, or a reasonable time FDA agrees to. During an outbreak or recall, FDA can ask for the information as an electronic sortable spreadsheet. Some smaller businesses are exempt from the spreadsheet format but still owe the records.

Records must be kept for two years.

What to do now

  1. List every product you handle and mark the ones on the Food Traceability List.
  2. Write down which critical tracking events you perform for each.
  3. Look at what your paperwork already captures. Invoices and bills of lading often contain most of the KDEs, but rarely the lot code.
  4. Decide where lot codes will come from and how they will appear on case labels.
  5. Ask your key suppliers and customers what they will send and expect.
  6. Run a mock trace: pick one lot and see how long it takes to find everywhere it went.

Where Lotcrumb fits

Lotcrumb is being built for small producers, packers and distributors. It pulls key data elements from the invoices, bills of lading and labels you already handle, and produces the sortable spreadsheet and traceability plan on demand. Join the waitlist for early access.
