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.
