Parmigiano-Reggiano makers are putting edible microchips the size of a grain of sand into their 90-pound cheese wheels to combat counterfeiters

• Makers of Parmigiano-Reggiano in Italy are adding microchips to their cheese wheels.
• It's the latest move to combat counterfeiters selling rip offs of the premium product.
• The chips, which are edible and placed on a food-safe label, cannot be read remotely.

The next time you dig into a bowl of pasta with freshly grated parmesan, you could accidentally be eating a microchip.
