I recently received an email warning me to check the packaging of my food for the logo depicted on the right. This logo indicates that your food has been irradiated to kill unwanted organisms that are living on the food. I was in disbelief when I first saw this. Is it safe to irradiate food? Does it change the nutritional value? What are the risks associated with ionizing radiation? This is almost as ridiculous as when the FDA approved the addition of live viruses on deli meats to kill off unwanted bacteria, several years ago. It makes me wonder, how does ionizing radiation know the difference between the "bad bacteria" and the "good bacteria"? Certainly the brains behind this operation know that bacteria are essential for proper digestion and elimination. They must know that the human body contains trillions of microorganisms, and that these organisms outnumber our cells.
