GS1/EPCIS Standards for Seafood Traceability

GS1 is the organization behind the barcode and global identifier standards (GTIN for products, GLN for locations, SSCC for logistics units) used across most global supply chains, and EPCIS (Electronic Product Code Information Services) is its companion data-exchange standard for recording and sharing discrete supply-chain events, an item was produced, shipped, received, transformed, in a structured, machine-readable format that different companies' systems can exchange without each needing custom point-to-point integration with every trading partner. For seafood specifically, applying GS1/EPCIS means a harvested lot gets a globally unique identifier at the point of harvest, and every subsequent event, processing, repackaging, shipping, retail receipt, references that identifier, letting any party in the chain query the full history of a specific lot using a shared standard rather than each company's own proprietary tracking scheme that stops working the moment product crosses a company boundary. Industry-specific implementation guidance, notably the Global Dialogue on Seafood Traceability's standard built on GS1/EPCIS, has emerged specifically to standardize which data elements (species, catch or harvest location, method, dates) seafood supply chains should capture at each event, addressing the broader traceability problem that generic retail traceability standards did not originally specify seafood-relevant fields. Adoption remains uneven because it requires coordinated investment across an entire supply chain rather than any single company acting alone, which is why large retailers and importers increasingly mandate GS1/EPCIS-compliant data as a supplier condition rather than waiting for voluntary industry-wide adoption.
