What should happen when a batch fails?

Define failure before the result arrives

A failure is a result or documented condition outside an applicable legal, safety, authenticity or internal acceptance criterion. The specification must name the parameter, unit, method or reference and decision rule in advance. Moving the line after seeing the number is not quality control.

The lot definition matters just as much. A report should connect to a clear batch or lot and a representative sample. If identity is uncertain, the first problem is not pass or fail; it is that the evidence cannot be reliably attached to the food.

A standard is credible when the uncomfortable result follows a pre-written path.

Hold first, explain second

When a potentially significant non-conformance arrives, the affected stock should be placed on hold and prevented from dispatch or further mixing. The organisation should identify related material, distribution status, retained samples and records without waiting for a polished narrative.

A hold is not the same as a final legal finding. It is a containment step that protects consumers and evidence while the result is reviewed. Clear status labels and system permissions help prevent an accidental release.

Review the evidence without shopping for a pass

The review checks sample identity, seal, chain of custody, laboratory competence, method, units, specification and any reported quality-control issue. A retest may be justified under a defined protocol—for example, using a retained counter-sample or investigating a documented laboratory deviation.

Repeatedly testing fresh hand-picked samples until one passes is not a neutral appeal. The retest rule should state who authorises it, which sample is used and how conflicting results are interpreted.

Investigate the route, not only the number

Root-cause work follows the batch backward through supplier, input, process, cleaning, storage, aggregation and sampling records. It asks what changed and whether other lots share the same exposure. Corrective action addresses the cause; preventive action reduces recurrence.

Supplier action should be proportionate and documented. A failed lot may require rejection, segregation, reprocessing where lawful, destruction or another controlled disposition. Commercial pressure cannot be the disposal method.

Escalate to recall when the food has moved

If affected food has entered the market and meets recall criteria, the Food Safety and Standards (Food Recall Procedure) Regulations, 2017 provide the regulatory framework. Distribution records, consumer communication, retrieval, reporting and final disposition become essential.

Recall messages should identify the product and batch clearly, state what people should do and avoid dramatic claims beyond the evidence. Speed and specificity help more than a vague announcement that an entire category is dangerous.

Close the loop visibly

The final record should show the decision, authority, quantity affected, disposition, root cause, corrective actions and verification that those actions worked. Farmers or suppliers whose material formed the lot need a fair explanation and access to relevant results.

Public transparency can protect legitimate confidentiality while still explaining the standard and response. A brand that only publishes passing certificates teaches readers to admire paperwork. A brand that explains its failure route teaches them how the system actually protects food.
