This is the symbol use in Japan to alert people of food that had been exposed to radiation.
Looks very ominous.
This is the symbol used by the FDA / USDA to inform us that the food we are purchasing has been processed with radiation
This looks more like a symbol for Green Peace
Since 1963, the US Food and Drug Administration (FDA) and the United States Department of Agriculture (USDA) have allowed the use of irradiation on a small number of foods available commercially to the public.
- 1963 – FDA approved the use of irradiation to kill pests in wheat and flour.
- 1985 – FDA approved port irradiation to control parasites that cause trichinosis.
- 1986 – FDA approved the use of irradiation to delay maturation, inhibit growth and disinfect certain foods, including vegetables and spices.
- 1992 – USDA approved irradiation of raw poultry to kill salmonella and other bacteria.
- 1997 – FDA approved irradiation of red meats.
Irradiation of food has been shown to kill and inactivate a number of food borne pathogens such as E. Coli 0157:H7, Bacillus cereus, lostridium botulinum, Listeria monocytogenes, salmonella, staphylococcus aureus, Campylobacter jujuni, Cyclospora, and Toxoplasma gondii. However, concerns about the safety, nutritional integrity, and cost of irradiated foods still exist and the environmental impact of irradiation technology and its long term effectiveness in dealing with the immense problem of contaminated food remain controversial
There are still many unanswered questions about the long term safety of irradiation. Furthermore, irradiation can only be used on a limited number of foods and does not address the larger problem of preventing contamination.
What is the difference between radiated and irradiated. Radiation is emitted from something and travels from its point of origin to somewhere else. When radiation hits something else (and is therefore stopped) the thing that has been hit is said to have been irradiated.
