When Walmart acts, the food industry notices. So when the retailer announced a produce traceability initiative (PTI) mandating standard case labels including GTIN, lot/batch#, voice pick code and pack or sell by date, Food Engineering wanted to know more. We spoke with Tom Kozenski of JDA Software about Walmart’s efforts to implement Produce Traceability Initiative standards and what it could mean for the future of fresh produce retail. Kozenski says proper labeling and tracking will provide improved product freshness and give all parties greater inventory visibility and control, lowering overall supply chain costs.
