Is the risk of food poisoning from cookies so great that this is a useful thing to do? Seems like most food poisoning comes from either veggies that were contaminated by the soil and then left unwashed or processed meat like hamburger. Controlling the production line of baked goods seems relatively easy by comparison. I highly doubt safety tracking is a worthwhile use of this technology. The bar code on the packaging does a better job of that because the poisoned person didn't eat the evidence.

From the Article

>Researchers have developed a way of printing edible QR codes -- a kind of barcode -- within cookies, meaning that the tag is embedded within the food itself. Crucially, the tag doesn't change the flavor or outer appearance of the cookie, and can be read using a backlight while the cookie remains intact. This new method has great commercial potential for improving food safety and traceability in an environmentally friendly way.

Yo Dawg, I heard you like cookies so much I put a cookie in your cookie.

To what end? Sounds like the ultimate pointless goal.
