FYI, from questions that I have asked, it appears that we will be importing data from the IUSDA FoodCentral data when OFF is missing a food or we see that changes have occurred. This may get us into the same situation that was noticed with the Fleury Michon data that comes via the producer app.
Ideally, I think that when we see different data, we would want to know whether this came from an earlier pull of the USDA data or from a person. I think that edits from a person should be respected over importable data, but we can flag the data for analysis when we see something in the imported data that would override a user edit.
See Is it okay for producers to overwrite user-contributed data with bad data daily?
