Tracing food is a dandy idea but this makes the usual blockchain
enthusiast error of assuming that if it's on the blockchain it must be
true.  Tagging the food and accurately identifying what each tag is
attached to is the hard part, not sticking the tag IDs in a database.

All the tags in the world won't help if a sleazy packer can just
put a tag for a clean field on produce from a dirty field.
