"transactional data"
Sounds way too modern.
Maybe stats for food sales should be regional, and not continent-wide. Then restrict them to traders, and make them spend hours to accumulate the data. You spend your hours, and learn about what happens in your area.
Then call it "Market price" or "Sale price." Basically, the data currently provided are simply irrelevant; they reflect literally nothing. Continental average actual sale prices would be useful.
