This is short sighted. You would at least be able to see exactly who was involved along the line. It would be public knowledge to find unreliable suppliers that had a higher rate of contamination. Also, it would be really cool to see exactly what farm something came from. It doesn't apply to a bag of cheetos but it definately does for a waygu beef steak.

That has nothing to do with a blockchain though - the data structure you use has no ties to the physical entities entering data into it. If there's a regulatory body enforcing compliance, why wouldn't that regulatory body just maintain a database to track the supply chain? More energy efficient, and it aligns the data with its oversight. If there's no regulatory body, then you're back to the original problem - nothing about a blockchain prevents dirty Farm A from entering Farm B into the ledger.
