The U.S. Food Supply Chain, traced end to end.

A working simulation of food supply-chain partners moving a product from farm to point of service — generating GS1 EPCIS 2.0 events at every Critical Tracking Event and rendering the FDA FSMA 204 Food Traceability sortable spreadsheet as it goes.

Scenario

Supply chain network

Each partner is a GS1 location (GLN). Critical Tracking Events light up as lots pass through.

Event stream 0 events

Press “Run the twin” to simulate the chain and emit EPCIS events.

Food Traceability records

One row per record, keyed to a Traceability Lot Code and Critical Tracking Event. Click any column header to sort. Export produces a CSV that opens directly in Excel.

No records yetRun the twin to populate the traceability spreadsheet.

EPCIS 2.0 event document

A standards-conformant EPCIS 2.0 JSON-LD document. ObjectEvents capture harvest, cooling, packing, shipping and receiving; a TransformationEvent captures fresh-cut processing.

No events yetRun the twin to generate the EPCIS 2.0 document.

One-up, one-back traceback

The decision the rule is built for: pick a lot at the point of service and reconstruct its path back to the originating farm — across transformations — in seconds, not days.

Lot under investigation

No lot selectedRun the twin, then trace any lot back to its farm of origin.

Scaffold note. This is a default build for review. GLNs, GTINs and SSCCs use the GS1 documentation prefix (0614141) and are illustrative. CBV bizStep / disposition vocabulary for the harvesting and cooling events should be validated against the GS1 “Application of GS1 Standards for FSMA 204” guidance, and the spreadsheet columns aligned to your FDA example file. Actors will be swapped to match the PFT pilot paper once it’s available.
