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

EU Regulation No. 178/2002 requires every food business operator to be able to identify:

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

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

Most bakeries still use binders of delivery receipts. The problem:

• Finding a batch in 6 months of delivery receipts takes 20 to 40 minutes.
• The ingredient-to-recipe link does not exist on paper. You know you received T65 flour batch 2024-0847, but which recipes did you use it in?
• Receipts get lost or become illegible: faded ink, torn pages, misfiled documents.

Responding to a product recall in 4 hours with paper binders is extremely ambitious.

The principle: every scanned supplier invoice is automatically linked to the relevant ingredients. Every ingredient is linked to the recipes that use it.

The traceability chain:

1. Supplier -> invoice/delivery receipt -> batch + date.
2. Ingredient -> linked to recipes that use it.
3. Recipe -> linked to the finished products sold.

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

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

With paper binders:

1. Find the March 5 delivery receipt: 10 min.
2. Identify recipes using butter: 15 min (from memory).
3. Determine affected production dates: 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: all recipes + production dates listed.
3. Total: under 2 minutes, comprehensive.

You do not need to digitize everything at once. Here are the steps:

1. Scan your supplier invoices upon receiving deliveries. Photo or scan, a single action.
2. Link each ingredient to its supplier in your software.
3. Your recipes are already entered: the ingredient-to-recipe link already exists.
4. Test it: run an internal recall drill once per quarter.

Within 2 weeks of practice, your team is fully autonomous.
