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

Get it straight, it's safe to separate.

IAFP - Cross contamination icon

Improper handling of raw meat, poultry, and seafood can create an inviting environment for cross-contamination. As a result, bacteria can spread to food and and other surfaces throughout the kitchen. Keeping uncooked meat, poultry, and seafood away from ready-to-eat foods like fruits, vegetables, and cold cuts helps prevent pathogens and other bacteria from contaminating the ready-to-eat foods.
