Lot Code

A lot code is an identifying code assigned to a specific production or packaging batch of food. It helps manufacturers, distributors, retailers and restaurants trace products through the supply chain and identify affected items during a recall or quality investigation. A lot code may contain letters, numbers or a combination of both.

Where to find a lot code

Lot codes are commonly printed or stamped on cases, cans, jars, vacuum packs, cartons and other food packaging. Their format is determined by the manufacturer and may be linked to a production line, facility, date, shift or batch.

Why lot codes matter in restaurants

• Identify whether a delivered product is included in a recall.
• Trace an ingredient to the supplier and production batch.
• Support investigation of a suspected quality or safety problem.
• Help isolate affected stock without discarding unrelated batches unnecessarily.
• Maintain records for supplier and regulatory follow-up.

Lot code versus date code

A lot code identifies a batch or production group. A best-before or use-by date communicates a quality or safety-related date according to the product and applicable rules. Some manufacturers encode production dates in the lot code, but the two terms are not interchangeable.

Chef’s tip: Keep the original case label or record the lot code when products are received and opened. If a recall is announced, compare the exact lot code and product details with the official notice.

Key distinction: A lot code supports traceability to a specific batch; it is not simply the product’s expiry date.
