Cheese lot lineage data for evaluating AI traceability
Cutting and repacking can give a cheese plant a hard document question.
NAICS 311513 · Cheese Manufacturing
Cutting and repacking can give a cheese plant a hard document question. Which finished lot actually descended from the source lot on the notice? FDA’s Food Traceability Rule resources describe additional records for covered foods and offer an example spreadsheet. Whether a particular cheese or activity is covered depends on the product and circumstances. A fictional lineage test can use the same type of evidence without representing a regulatory determination. FDA traceability rule resources · FDA example traceability records
Have an invented aged lot split into two pack sizes. Add a second source lot packed on the same day with a similar ID. Provide input and output lot mappings, original quantities and units, and an expected list of affected output IDs. Include one missing link and score whether the model asks for the missing packing record. Avoid using total quantity alone to determine lineage.
Supplier records and customer shipment data can remain private. Replace both with fictional IDs and use an internal quality specialist to check the expected result.

Original Fiund exercise
A source-lot notice follows explicit packing links across pack sizes
An original fictional trace graph uses empty-package aliases and arbitrary counts. No cheese, real notice, shipment, supplier, regulatory coverage or recall decision appears.
| Record | Source | What it records |
|---|---|---|
| CHL1 | Source notice | Practice source L-A is the target. Distinct source L-AA arrives same day and has a similar label. |
| CHL2 | Packing map | L-A explicitly produces outputs A-S and A-L in two pack sizes. L-AA produces AA-S. Separate exact original mapping events. |
| CHL3 | Loose output | Output X shares packing date and same count as A-S, but parent link missing. No reviewed relationship to either source. |
Question for the model
Which output IDs have supported L-A ancestry, and can date or quantity determine whether X belongs in the list?
Show the reference answer and checks
CHL1 and CHL2 support A-S and A-L as documented L-A descendants despite different package sizes. AA-S belongs to distinct L-AA and must not be included on name similarity. CHL3's X has no parent record, so shared date and quantity cannot establish whether it is affected in the fictional trace. Return the supported output list and request X's packing link without making a real recall, release or regulatory coverage decision.
- Matching a similar source ID instead of following exact packing links.
- Inferring affected output from equal quantities or assuming the documented set covers an unlinked output.
Fields to preserve
- Source and output lot IDs
- Defines trace targets.
- Packing event and package level
- Preserves split lineage.
- Missing parent and reviewer scope
- Limits the result.
Test another case
Add a reviewed X-to-L-AA map. Require X to leave the unresolved list without entering L-A's supported descendants.
Use original synthetic maps reviewed by appropriate staff. Exclude actual supplier and shipment data; no regulatory or product action is authorized.
