Isn't this such a cute symbol. It looks like a label for organic, or all natural products. https://www.backyardchickens.com/forum/uploads/11438_radura.gif No, its the symbol for irradiated food, including eggs. Even worse, the term pasteurized is allowed to be used instead of irradiated. Irradiation is supposedly a valuable tool to combat Salmonella in eggs. Thats a good thing, right? Safer food, right? Among many unseemly side-effects, irradiation destroys vitamins, nutrients and essential fatty acids in food; leads to the formation of free radicals, which set off chain reactions that tear apart cell membranes and make the body more susceptible to cancer and diabetes; can spawn mutant forms of E. coli, Salmonella and other harmful bacteria, making them more difficult to kill; can lead to the formation of carcinogens and other toxic chemicals such as benzene, formaldehyde, octane, butane and methyl propane; can corrupt the flavor and texture of foods, leading to meat that smells like a wet dog and onions that turn brown; kills beneficial microorganisms, such as the yeasts and molds that help keep botulism at bay; and does nothing to remove the feces, urine, pus, vomit and tumors often left on beef, chicken, and lamb due to filthy and inhumane slaughterhouse conditions. Moreover, experiments conducted over the past half-century at universities and research institutions throughout the world have revealed that lab animals fed irradiated food have suffered premature death, cancer, reproductive and immune problems, liver and kidney dysfunction, low birth weight, nutritional muscular dystrophy and chromosomal damage, among many serious health problems. FDA officials not only have ignored these problems, they have relied on questionable research that has obscured the well-documented hazards of exposing food to radiation. The FDA, for instance, cited only 7 of more than 400 scientific studies to determine that irradiated food is safe to eat. In all seven of these studies, researchers fudged their results by using doses of radiation at or far below levels ultimately approved by the FDA, added nutrients to the diets of lab animals to offset the harmful effects of irradiation -- and, in at least two studies -- both. Four of the seven studies have never been published in peer-reviewed journals. And three of the studies have never been translated into English.
