How does a microchip help when apparently the name "Parmigiano Reggiano" isn't protected in the US? The article doesn't seem to differentiate between actual counterfeit that claims to be from the region vs. cheese that is made in the US and sold as made in the US. The chips would only help against the second kind. Also, the article claims that parmesan is one of the oldest cheeses of humankind even though it is less than a thousand years old while people have made cheese since the stone age. Personally, I don't really see a reason, that people in the US should only be able to call parmesan from Italy parmesan if most parmesan sold there is already made in the US. I don't think it really matters where the cheese is produced and it doesn't really make sense, to transport it over the ocean when it can be produced locally.
