Food traceability: how to trace a flour batch from supplier in 2 minutes

Every food business operator must be able to identify:

• Who supplied each raw material (supplier + contact details).
• What: type of product, lot number, delivery date.
• To whom you sold (for B2B sales only).

In the event of a food safety alert (product recall), you must be able to answer the question: "Which products did you use the flour from lot X, delivered on Y, in?" The answer must come in under 4 hours.

Most bakeries still rely on binders full of delivery notes. The problem:

• Finding a lot in 6 months' worth of delivery notes takes 20 to 40 minutes.
• The ingredient-to-recipe link doesn't exist on paper. You know you received T65 flour, lot 2024-0847, but which recipes did you use it in?
• Notes get lost or become unreadable: faded ink, torn sheets, misfiling.

4 hours to respond to a product recall with paper binders is very ambitious.

The principle: each scanned supplier invoice is automatically linked to the ingredients involved. Each ingredient is linked to the recipes that use it.

The traceability chain:

1. Supplier → invoice/delivery note → lot + date.
2. Ingredient → linked to the recipes that use it.
3. Recipe → linked to the finished products sold.

When a recall comes in, you type the ingredient name or the lot number. In 2 clicks, you have the list of every product affected and the production dates.

Scenario: your supplier informs you that butter lot BT-2026-0312, delivered on March 5, is potentially contaminated with listeria.

With paper binders:

1. Find the delivery note from March 5: 10 min.
2. Identify the recipes that use butter: 15 min (from memory).
3. Determine the production dates affected: 20 min (paper schedule).
4. Total: 45 minutes minimum, with a risk of missing something.

With digital traceability:

1. Search "BT-2026-0312": 10 seconds.
2. Results: every recipe + production dates listed.
3. Total: under 2 minutes, comprehensive.

No need to computerize everything at once. Here are the steps:

1. Scan your supplier invoices at delivery. A photo or a scan, in a single motion.
2. Link each ingredient to its supplier in your software.
3. Your recipes are already entered: the ingredient → recipe link already exists.
4. Test it: run an internal recall drill once a quarter.

After 2 weeks of practice, your team is up and running on its own.
