Food recall scope: a shared ingredient lot
Trace the suspect ingredient lot into actual production batches, including intermediate mixes and rework, then match affected finished packs to customer deliveries. Keep uncertain links within the investigation and explain exclusions with evidence. China-side factory records can be gathered by Cambridge China Bridge.
Start with the ingredient, not the product name
Hold the suspect ingredient and potentially affected finished stock while investigating. Record the supplier lot exactly as printed, with photographs, receipt records and any internal codes assigned after unpacking. Ask the Chinese supplier whether the lot was split, blended or supplied under other codes, and request the underlying records rather than a general assurance.
Create a scope register with a row for each potentially affected finished batch. Record the ingredient link, evidence source, stock position and whether inclusion is confirmed or uncertain. Use our guide to batch traceability for the underlying record chain. Our imported-product recall guide covers non-food goods; this guide addresses ingredient use across foods.
Prove actual recipe and production links
Use recipes to identify candidate products, then check actual ingredient issue records, weighing sheets and production logs. A recipe shows what should have been used; it does not prove which lot entered a particular run. Include recipe revisions, substitutions, contract manufacturers and intermediate mixes that were later divided between products.
Match each production batch to its finished-pack codes, brand, pack size and date markings. Reconcile ingredient receipts against remaining stock, recorded use, waste and transfers, allowing for documented processing changes. Investigate unexplained differences. Before excluding a batch, record both the production evidence and the hazard assessment supporting that decision; do not rely only on a different product name or a passing sample.
Follow rework into later batches
Trace retained dough, trim, returned mixes and other rework from their source batches into every receiving batch. Continue through subsequent reuse until the recorded chain ends. Check shared rework containers, pooled material and carry-over between runs. Rework added later can connect the suspect ingredient to products whose original recipes never listed it.
Where records cannot distinguish the source of pooled rework, keep the receiving batches within the investigation and discuss broader protective action with the authority. Ask a food-safety specialist to assess relevant carry-over and cleaning evidence. Do not assume dilution or heating removes the hazard. Keep historical rework tracing separate from any proposed treatment of held food, which should be discussed with the authority.
Map affected packs to customer distribution
For each affected finished batch, match dispatch records to business customers, delivery locations and onward distributors. Include private-label stock, catering deliveries, online fulfilment and overseas destinations. Ask customers to confirm stock held, onward supply and consumer sales separately. A delivered notification does not establish that stock has been blocked or recovered.
If affected unsafe food has reached consumers, it needs to be recalled. Prepare product-specific messages showing recognisable packs, affected codes and date markings, the reason and the action to take. Give business customers wording for onward communication and request confirmation of implementation. Track unresponsive recipients and unresolved stock. Keep supplier recovery discussions separate through our guide to faulty goods and claims.

Send a usable authority update
Contact your local authority food-safety team or port health authority about the incident and proposed scope. If you believe unsafe food has reached consumers, tell the Food Standards Agency incidents team. Scotland has a different reporting route. Notification should not wait for complete information: send available details and identify what is still being checked.
Prepare a dated pack containing the hazard evidence, ingredient identity, finished-batch register, recipe and rework links, customer distribution, overseas destinations, held stock and actions taken. Explain each exclusion and unresolved link. Assign an owner to follow up missing records, issue updated scope lists and correct customer notices when scope changes. Retain earlier versions so the authority can see why decisions changed.
Frequently asked questions
Do all products using the ingredient need recalling?
Investigate every actual use, including intermediate mixes and rework. Decide protective action using batch evidence and the hazard assessment. A shared recipe alone does not establish which lots were used.
Can I exclude a batch that passed testing?
Do not use a passing sample alone to narrow the scope. Ask a food-safety specialist whether sampling addresses the hazard and batch variability, then document the evidence supporting any exclusion.
What if rework records are missing?
Treat the link as unresolved. Hold potentially connected stock, reconstruct movements from production and staff records, and discuss wider protective action with the authority.
Should I wait for the Chinese factory's report?
No. Notification should not be delayed because information is incomplete. Send available details, flag unknowns and update the authority as factory and distribution records arrive.
