The document discusses using barcode technology for traceability in the fresh food industry. It describes challenges around short shelf life and new compliance requirements that are driving fresh food producers to implement barcode solutions. It then provides an overview of options for growers, processors, and packers/shippers to implement barcode labeling in fields and facilities for production reporting, inventory management, lot traceability, and shipment verification throughout the supply chain. Key points include initiating lot traceability through field labeling, options for mobile labeling in fields, and software solutions for production management with features like palletizing, commingling, and carton-level traceability to facilitate recalls.

FLEXIBILITY
The fresh food industry encompasses everything from fish to
produce to meat and poultry to berries and citrus fruits. Each
product has its own unique challenges for production, han-
dling and food safety. The following is a discussion of avail-
able and scalable solutions for fresh food growers, proces-
sors and packers.
