Radiation can rid food of bacteria

Between the spinach scare in the fall and the E. coli outbreak at Taco Bell, you may be worried about what you're feeding your family.

Now some experts say radiation could be the answer to all those problems.

“We expose food to a very high energy source, and that causes ionization of DNA so effectively we are killing these bacteria by damaging their DNA,” said Dennis Olson of Iowa State University.

Irradiated foods are available in stores, usually costing a few additional cents.

The process has been approved by the Food and Drug Administration. Critics say more testing needs to be done.
