Food traceability: the details
In the European Union it has been mandatory since 2005 under Regulation (EC) 178/2002. The minimum requirement is summed up as “one step back, one step forward”: every business must be able to identify its immediate suppliers and customers. In practice, customers and quality certifications also ask for internal traceability: which raw materials and processes are behind each lot that ships.
The real test is a recall. If a problem appears, you have to find within hours which lots are affected and where they are, and the finer the record, the less product gets pulled. With paper and spreadsheets that takes days; with the lot captured at every step—intake, processing, packing, shipping—it’s a query.
