Health Canada has published final regulations this week in the Canada Gazette, Part II, which permit the sale of fresh and frozen raw ground beef treated with irradiation.

Health Canada developed the new regulations after conducting a thorough assessment, and concluded that irradiation is a safe and effective treatment to reduce harmful bacteria in ground beef.

Irradiation is an optional tool that the food industry can use to treat certain foods to maintain quality or enhance safety. The United States has permitted the irradiation of fresh and frozen ground beef since 1999, and more than 60 countries worldwide permit irradiation of various foods. It is already approved in Canada to treat potatoes, onions, wheat, flour, spices and seasoning preparations.

During irradiation, food is exposed to low levels of a type of energy called ionizing radiation. Benefits of this kind of food processing may include a reduction in levels of harmful bacteria, such as E. coli, Salmonella and Campylobacter; prevention of premature spoilage; and a longer shelf life.

Ground beef that is irradiated retains its nutritional value, taste, texture and appearance. All irradiated foods must be labelled. If the food is not packaged, a sign containing this information must be displayed at the point of sale.

The federal government says that permitting this technology will give the beef industry another tool to enhance food safety.
