How to Manage Lot Codes and Recalls for Packaged Food

Why lot codes matter in packaged food

Set up the process before you need it

1. 01

   Create a lot code rule

   Decide how you will read and store each lot code before products enter inventory. Use one format for every item line, and keep it on the case label, receiving record, and outbound order record. If a supplier sends a different format, normalize it in your system so staff can search it the same way every time. Consistency matters because recalls move faster when one code means one set of records.

2. 02

   Capture lot data at receiving

   Train receiving staff to check the lot code on every inbound case or pallet that requires traceability. Record the code with the item, quantity, and receive date. If a shipment contains multiple lots, split the receipt by lot instead of combining them into one line. That keeps inventory clean and makes later holds easier to apply without guessing which units are affected.

3. 03

   Link lots to outbound orders

   Your shipping record should show which lot codes left the warehouse and which customer received them. If you sell by case, pallet, or mixed order, the shipment detail still needs the lot trail. This is the part many teams skip. When you only know that ten cases shipped, you still do not know which ten. Tie every shipment line to a lot before the order closes.

4. 04

   Use a hold process for suspect inventory

   When you receive a complaint, temperature issue, label error, or supplier alert, move the lot into a visible hold status. Do not leave it mixed with saleable stock. Separate physical inventory, block it in your records, and add a clear reason for the hold. That lets warehouse staff avoid accidental picks and gives management one list to review when the food recall process begins.

5. 05

   Build a recall contact list

   Keep current contacts for suppliers, carriers, brokers, customers, and internal staff who must act during a recall. The list should include names, roles, phone numbers, and email addresses. Store it with your traceability records, not in one employee's inbox. During an event, you need one source of truth that can support notice, confirmation, and follow-up.

6. 06

   Document the final disposition

   After you identify affected lots, record what happened to each one. Some product is quarantined, some is returned, and some is destroyed under control. Save the reason, the date, and the person who approved the action. If you need to explain your traceability later, that final record is as important as the receiving log.
