The 'May Contain' That Wasn't Checked
A bakery produces 400 packaged flapjacks per day on a line that also handles almond bakewells. The flapjack recipe contains no nuts, and the packaging carries no 'may contain nuts' statement because the previous production manager decided the line was 'cleaned well enough.' A new allergen risk assessment is commissioned after a customer with a tree-nut allergy reports a reaction after eating a flapjack. Investigation finds: the line is brushed between runs but not wet-cleaned; shared utensils are used for both products; the bakewell tray liners are reused; and staff change aprons only at breaks. The bakery's due-diligence file contains a signed cleaning schedule but no verification swabs or records.
1. Assess whether the absence of a 'may contain' statement was defensible, and identify the control failures that made cross-contact likely.

Not defensible. A 'may contain' statement is not a substitute for controls, but its absence is a positive claim that the producer has assessed and controlled the risk. Here no valid assessment supports that claim.
Control failures:
- Cleaning method: brushing alone does not remove allergen residues from textured surfaces or equipment; it redistributes them. Wet cleaning or validated dry cleaning is needed.
- Shared utensils and reused tray liners: direct transfer routes. Liners that have contacted almond product should not be reused for a nut-free product.
- Aprons changed only at breaks: allergen dust and crumbs transfer on clothing between runs.
- No verification: a signed schedule proves someone signed, not that cleaning worked. Without swabs or visual/ATP checks recorded, there is no evidence the control is effective.
Conclusion: cross-contact was foreseeable and uncontrolled. The product should either carry a precautionary statement reflecting a genuine, assessed risk, or the controls must be upgraded so the risk is eliminated - the current position is the worst of both worlds: no warning and no control.
2. Recommend a corrective action plan with verification, and explain how you would decide whether a precautionary allergen label is still needed afterwards.

Corrective actions:
- Segregate or sequence: run nut-free products first, or dedicate a line/shift where feasible.
- Validated cleaning: define a written procedure with detergent, contact time and rinse; include utensils and trays.
- Dedicated equipment: colour-coded utensils and separate tray liners for nut-containing runs; single-use liners.
- Gowning: apron change between product runs, not just at breaks.
- Verification: allergen swab or ATP testing after cleaning, with results recorded and retained; periodic trend review.
- Records: cleaning sign-off tied to specific batches, with a named verifier.
Deciding on the label: the precautionary statement is justified only if, after controls, a residual risk remains that cannot be eliminated. If verification consistently shows no detectable residue after validated cleaning, the assessed risk may be low enough to omit the statement - but this must be documented in the risk assessment, reviewed if the process changes, and supported by verification data, not by assertion. If controls cannot guarantee separation, the label stays.
