Researchers at the USDA have developed an edible coating that will actually kill bacteria on fresh produce. It is intended to be an alternative to conventional or chemical produce washes that will keep the food just as fresh, if not fresher, and reduce the risk of food-borne illness that is associated with fresh produce. The coating is made of apple puree and oregano oil. The oregano oil is a natural antibacterial agent and did a better job at eliminating bacteria than other oils, while the apple puree helps the coating adhere to the fruit/vegetable and takes the edge off the oregano flavor. So far, it has only been tested on E. Coli, where the oregano has been shown to kill at least half of all present bacteria in under 3 minutes. The are planning on developing wrappers in other flavors, as well as targeting different bacteria in the future, including salmonella and listeria.

The products could be commercially available in as little as two years, but they are now being tested by some selected companies and stores.
