About the Radura

Since 1986, all irradiated products must carry the international symbol called a radura, which resembles a stylized flower.

FDA requires that both the logo and statement appear on packaged foods, bulk containers of unpackaged foods, on placards at the point of purchase (for fresh produce), and on invoices for irradiated ingredients and products sold to food processors.

Processors may add information explaining why irradiation is used; for example, "treated with irradiation to inhibit spoilage" or "treated with irradiation instead of chemicals to control insect infestation."

Accurate plant records are essential to regulation because there is no way to verify or detect if a product has been irradiated, or how much radiation it has received.

Food Safety Tip of the Day

It's safe to bite when the temperature is right

Thermy

The only way to know food has been cooked to a safe internal temperature is to use a food thermometer. Fortunately, thermometers are high-tech and easy to use. Research shows that while cooking by "color" is frequently done, it can be misleading. Correct use of the right thermometer provides confidence that foods are adequately cooked, resulting in a safe, delicious meal.
