Traceability

One graph. Every lot. Every handoff.

A Loamy traceability graph connects the complete path of a food shipment from grower to retail, with certificates and Critical Tracking Events on every edge.

Graph Architecture

Directed graph, not a spreadsheet

Most food safety systems store traceability data in flat tables. A flat table can tell you what a lot contains. A directed graph can tell you where every unit of that lot went, through how many transformations, and whether each step carried a valid certificate. That is the difference between spreadsheet traceability and Loamy traceability.

Each node in the Loamy graph represents a unique lot at a specific supply chain tier. Each edge represents a Critical Tracking Event: a handoff where something was received, shipped, transformed, or cooled. Certificates attach to edges, not just to the lot record, so you can verify that a specific certificate covered a specific handoff.

Recall Response

What a Loamy recall query returns

A recall starts with a lot code or ingredient name. Loamy traverses from that starting node through every downstream connection and returns a structured report within seconds.

Data Captured

What Loamy stores on every node and edge

Lot Identifier
The traceability lot code as defined under FSMA 204, extracted from the certificate and matched to your internal lot numbering convention.
Critical Tracking Event Type
One of six FDA-defined CTEs: Growing, Receiving, Transforming, Creating, Shipping, or Cooling, recorded at each supply chain handoff.
Quantity and Unit of Measure
Case counts, pallet quantities, and weight measurements as they appear on each certificate, normalized to a consistent unit schema across suppliers.
Certificate Reference
The parsed certificate ID, issuing party, test results, and compliance status, attached to the edge where that certificate covered a handoff.
Location and Business Identifier
Shipping and receiving location, business name, and any GSTIN or FDA Facility Registration Number referenced in the original documents.
Timestamp Chain
Harvest date, ship date, receive date: every timestamp present in the certificate chain, forming an auditable timeline across the full supply path.
