Beware of produce or food products bearing this symbol – It is the radura symbol, which represents food has been irradiated.
The symbol RADURA is used as a symbol of quality exclusively for food processed by ionizing radiation – the controversial practice of infiltrating food with high levels of x-rays (ionizing radiation) to destroy disease causing pathogens. Unfortunately, in the process of irradiation, other hazards arise, like the creation of toxic free radicals, vitamin and nutrient loss, and the formation of carcinogenic chemicals.
The FDA has approved, this week, the production and sale of irradiated lettuce and spinach on all conventional produce, and will be available at your local markets Mid-September.
The labeling is required in supermarkets, although does not include restaurants.
