Every food and beverage business can describe its traceability process. Fewer have tested it against the system, end to end, on a day when nothing was wrong.
The question a recall asks is simple: which batches of finished product used this lot of raw material, and where did they go? The answer depends entirely on what was recorded weeks earlier, at receipt, at production and at dispatch. If one of those steps was skipped or keyed later from paper, the chain breaks at exactly the point you need it.
Traceability is a property of the whole process
It is tempting to treat lot tracking as a feature to switch on. It is closer to a discipline the system has to enforce. Lots need to be captured when goods arrive, consumed against production orders as they are used, and assigned to shipments as they leave. Each step has to be quick enough that people on the floor do it properly, every time.
Where that isn’t true, the gaps are predictable. Receipts are posted in bulk at the end of the day. Production consumes “the usual” lot rather than the one actually used. Returns come back without the lot being recorded at all. None of these look serious until the day someone asks for a trace.
Run a mock recall
The most useful test is also the simplest. Pick a raw-material lot from last month and ask the system for everything downstream of it: the production orders, the finished lots, the customers. Then pick a finished lot and trace it back. Time both. Note every point where someone had to leave the system to find the answer.
If the trace takes minutes and stays inside the system, you are in good shape. If it takes an afternoon and three spreadsheets, that is the work to do now — before a regulator or a customer asks you to do it under pressure.
