Mock Recall in 4 Hours: Passing the Traceability Test in Front of an Auditor

A mock recall is a practical exam: pick a batch, then prove within a set time that you know where its materials came from and where every case went. Most auditors expect completion within 2–4 hours.

Legal basis: EU 178/2002 requires one-step-forward, one-step-back traceability for every food business operator, while US FSMA 204 requires extended traceability records (KDEs) for a list of high-risk foods.

Preparation before the test: a legible lot code on every pack, raw material receiving records linked to the batch, production records, and distribution records tying the batch to customer, quantity and date.

Step 1 — Activation: define the batch and the assumed cause (e.g. foreign body complaint) and log the start time. Time is part of the test.

Step 2 — Trace back: from the batch to every raw material, supplier and delivery note. Goal: find out whether other batches share the same material.

Step 3 — Trace forward: every quantity produced from the batch and where it is now — in stock, in transit, at the customer, or consumed. The mass balance must reconcile: produced = recovered + remaining + sold.

Step 4 — Decision and notification: recall classification (Class I/II/III), hold or withdrawal decision, and draft notices to customers and the competent authority.

Pass criteria: ≥ 99% of the quantity accounted for within the target time, with documents supporting every figure. Anything less is recorded as a non-conformity.

Failures that sink the test: illegible lot codes, sales recorded without a batch number, samples and waste not accounted for, and no up-to-date out-of-hours customer contact list.

The Complaints & Recall tool in NutriCard runs a simulation timer and documents the investigation, mass balance and classification decision in a single auditor-ready report.
