FOOD IRRADIATION-A Safe Measure

FOOD IRRADIATION ISSUES

Irradiation does not make foods radioactive, just as an airport luggage scanner does not make luggage radioactive. Nor does is cause harmful chemical changes. The process may cause a small loss of nutrients in foods, but no more so than with other processing methods such as cooking, canning or heat pasteurization. Federal rules require irradiated foods to be labeled as such to distinguish them from non-irradiated foods.

Consumer Safety

Food safety is a subject of growing importance to consumers. One reason is the emergence of harmful bacteria or evolving forms of older ones that can cause serious illness. A relatively new strain of E. coli, for example, has caused severe, and in some cases life-threatening outbreaks of foodborne illness through contaminated products such as ground beef and unpasteurized fruit juices.

Scientists, regulators and lawmakers, working to determine how best to combat foodborne illness, are encouraging the use of technologies that can enhance the safety of the nation's food supply.

Facts About Irradiation

Many health experts agree that using a process called irradiation can be an effective way to help reduce foodborne hazards and ensure that harmful organisms are not in the foods we buy. During irradiation, foods are exposed briefly to a radiant energy source such as gamma rays or electron beams within a shielded facility. Irradiation is not a subsitute for proper food manufacturing or handling procedures. But the porcess, especially when used to treat meat and poultry products, can kill harmful bacteria, greatly reducing potential hazards.

The Food and Drug Administration has approved irradiation of meat and poultry and allows its use for a variety of other foods, including fresh fruits and vegetables, and spices. The agency determined that the process is safe and effective in decreasing or eliminating harmful bacteria. Irradiation also reduces spoilage bacteria, insects and parasites, and in certain fruits and vegetables it inhibits sprouting and delays ripening. For example, irradiated strawberries say unspoiled up to three weeks, versus three to five days for untreated berries.

Food irradiation is allowed in nearly 40 countries and is endorsed by the World Health Organization, The American Medical Association and many other organizations.

Studies show that consumers are becoming more interested in irradiated foods. Consumer research conducted by a variety of groups, including the American Meat Institute, the International Food Information Council, the Food Marketing Institute, the Grocery Manufacturers of America, and the National Food Processors Association has found that a large majority of consumers polled would buy irradiated foods.

Some special interest groups oppose irradiation or say that more attention should be placed on food safety in the early stages of food processing. Many food processors and retailers reply that irradiation can be an important tool for curbing illness and death from foodborne illness. But it is not a substitute for comprehensive food safety programs throughout the food distributin system, nor is it a substitute for good food handling practices in the home.
