No, sorry, I meant that M49 codes are well-established in the same way 
as the ISO country and language codes we're already using in OSM. I was 
suggesting that you'd use, for example:

* food_origin:chocolate=MX for chocolate from Mexico
* food_origin:chocolate=419 for chocolate from Latin America more generally

or perhaps:

* food_origin:salmon:wikidata=Q43182728 for salmon caught in the 
Northeast Atlantic

Human-readable names for this purpose, whether localized or unlocalized, 
would only complicate what's already a relatively complicated tagging 
scheme.
