Record split and combined batches without losing their source links.
Distinguish traceability and information from proof of safety or quality.

Similar produce can have different histories

Two crates can look alike while coming from different fields, dates or handling conditions. Once their labels are lost, their appearance may not recover that history. A useful batch record preserves the connection before the produce moves into the next stage.

A batch is an identified quantity grouped under stated conditions. Its definition depends on the operation: one field and harvest period, for example, may be more useful than an entire season's output. State the grouping rule so later users know what the identifier actually represents.

An identifier needs linked observations

A code becomes useful when it connects to origin, crop and relevant cultivar, harvest date or period, quantity and units, and the people or operations involved. Record relevant condition observations and the destination or intended use. The exact information needed varies among food and material chains.

A date alone may be insufficient if several fields are harvested that day. A container number alone may be insufficient if containers are reused. Choose a durable link between the physical batch and its record, and retain the meaning of every code rather than relying on memory.

Changing the batch creates another link

If a batch is divided, each outgoing portion must retain a link to its parent. If batches are combined, the new identifier must link to every contributing source. Changing the label should not erase those relationships.

Quantities help check whether the record makes sense. Use consistent mass bases and account for additions, removals and remaining inventory. A water-loss or sorting step can change quantity without changing the origin; record the step rather than forcing incoming and outgoing numbers to agree.

Preserve the parent through a split

Original hypothetical identity and mass example; no losses, additions or remaining inventory. Traceability does not establish safety.

Read the diagram as text

Invented batch H splits without loss into 60 kg H-A and 40 kg H-B. Both child records retain the parent link.

Parts

H: 100 kg: Source and handling record
H-A: 60 kg: Parent H + destination A
H-B: 40 kg: Parent H + destination B

Connections

H: 100 kg → H-A: 60 kg: split
H: 100 kg → H-B: 40 kg: split

Information travels with the intended product

A receiving operation needs information that helps it handle and use the material appropriately. Relevant requirements can include condition and quality specifications, suitable storage or transport conditions, and product-specific safety information. An ingredient's composition or allergen information can matter beyond the original farm.

Define who provides the information and who checks it at receipt. A measured temperature with its time and location is more informative than an unexplained “cooled” entry. Food-contact and labelling requirements depend on product and jurisdiction; this article supplies the information structure rather than a universal compliance form.

Knowing the source does not remove a hazard

Traceability helps identify affected batches and destinations when a problem is investigated. It does not prevent every contamination event, establish adequate processing or make an unsuitable product suitable. Food-hygiene and preservation controls remain separate, linked responsibilities.

Similarly, matching the mass record does not prove every recorded condition is correct. Instruments, observations and data entry can fail. Preserve uncertainty and missing information explicitly; inventing a value makes a tidy-looking record less useful for the next decision.

Can the record answer a real question?

Take one outgoing batch and ask which source quantities contributed to it, what happened during handling and where its portions went. Then start with a source batch and trace its outgoing destinations. These checks reveal broken links that a list of codes alone can conceal.

The diagram follows an invented split. It establishes quantity and identity links only. A useful system can be simple, provided records remain readable, accessible and connected as containers, owners and processes change. Review actual receiving requirements rather than collecting fields nobody can interpret.

Worked examples

Follow an outgoing split

An invented batch H contains 100 kg of produce. It is split without loss or remaining inventory into 60 kg sent as H-A and 40 kg sent as H-B. What should remain linked?

60 + 40 = 100 kg, so the stipulated split closes the mass balance.
Both H-A and H-B link to parent H and retain relevant source and handling information.
Record each destination and quantity. The receiving businesses can then connect their new identifiers to these outgoing portions.

Two child identities with parent, quantity and destination links. A matching balance supplies no safety certificate.

Keep both parents of a mixed batch

Suppose a new 100 kg batch M combines 60 kg from source X and 40 kg from source Y without loss or additions. Can its record name only X because X supplied more?

Both X and Y contributed; 60 + 40 = 100 kg.
M needs links to both source identities and their quantities.
The 60% and 40% mass shares describe this mixture. They do not establish hazard probabilities or how a contaminant would be distributed.

No. Both origins remain relevant, and the mixture requires its own identity.

Check your understanding

Can matching appearance recover a lost field and handling history?
Show answer and reasoning
Not reliably.
Physical similarity does not identify the relevant production and transfer records.
Does a complete batch record prove validated cooling or absence of contamination?
Show answer and reasoning
No.
Records support investigation and decisions; process and hazard controls require their own evidence.
If 100 kg enters and 95 kg leaves a recorded step, should the operator simply rewrite the incoming amount as 95 kg?
Show answer and reasoning
No.
Investigate and record loss, removal, inventory or measurement uncertainty rather than hiding the difference.

Key ideas

Link identifiers to origins, quantities, conditions and destinations.
Preserve every source link when material is split or combined.
Use records to support decisions alongside actual quality and safety controls.
