I don't disagree with your example (while ISO 900x is prevalent there are at least two other, generally equivalent and widely used, food safety and quality certifications out there). And yes, RFIDs are great and I personally wish were used a bit more extensively. What was talked about today is the potential to greatly reduce recall event time lines, FDA investigations, etc. The issue was described as: 1. The only FDA traceability requirement being 1 up and 1 down in the supply chain from the manufacturer. Which leads to 2. 2. The lack of interoperable data from farm to retail store. If there is a lot of lettuce with E Coli from one farm, which went to five ready to eat manufacturers and eight produce packers, all of whom have different lot code designations, and all of whom ship to numerous distributors who in turn ship to even more numerous retail outlets, you end up with a very complex and time consuming traceability process.
