What is food irradiation?
Disease Listing, Food Irradiation | CDC Bacterial, Mycotic D...Food irradiation is a promising new food safety technology that can eliminate disease-causing germs from foods. Like pasteurization of milk, and pressure cooking of canned foods, treating food with ionizing radiation can kill bacteria and parasites that would otherwise cause foodborne disease. Similar technology is used to sterilize medical devices so they can be used in surgery or implanted without risk of infection.
Related QuestionsWhat is the CDC's position on food irradiation?
Disease Listing, Food Irradiation | CDC Bacterial, Mycotic D...CDC has stated that food irradiation is a promising new application of an established technology. It holds great potential for preventing many important foodborne diseases that are transmitted through meat, poultry, fresh produce and other foods. An overwhelming body of scientific evidence demonstrates that irradiation does not harm the nutritional value of food, nor does it make the food unsafe to eat.
Related QuestionsIs food irradiation safe?
Tulsa Health Department - Frequently Asked QuestionsMany health experts agree that using a process called irradiation can be an effective way to help reduce food-borne 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 substitute for proper food manufacturing and handling procedures.
Related QuestionsIs irradiation of food just like pasteurization of milk?
Disease Listing, Food Irradiation | CDC Bacterial, Mycotic D...Irradiation has the potential to be used like milk pasteurization in the future. We have confidence in the safety of pasteurized milk for several reasons. The milk is graded and tested to make sure that the milk is clean enough to pasteurize in the first place. Careful industry standards and regulations monitor the effectiveness of the pasteurization process.
Related QuestionsWhat about the effect of irradiation on food packaging materials?
Disease Listing, Food Irradiation | CDC Bacterial, Mycotic D...The food to be irradiated will often already be in its final package. This raises the question about whether the irradiation has any effect on the packaging that might be transferred to the foods. The effect of irradiation on plastics and other packaging was investigated in the 1960s and early 1970s, in order to identify safe packaging materials for use in the space program. A limited number of materials have been approved for use in packaging food that is to be irradiated.

Related QuestionsHow is food irradiation regulated?
Food IrradiationThe Food and Drug Administration (FDA) regulates all aspects of irradiation: what products it can be used on, what dose can be used, and how those products are labeled. The U.S. Department of Agriculture (USDA) is responsible for the inspection and monitoring of irradiated meat and poultry products and for the enforcement of FDA regulations concerning those products. Since 1986, all irradiated products must carry the international symbol called a radura, which resembles a stylized flower.
Related QuestionsHow much a typical food irradiation facility costs?
Frequently Asked QuestionsThis will depend on many parameters including type of food, throughput etc. Estimated cost of a typical food radiation processing facility is in the range of Rs. 6 ? 8 crores excluding land cost.
Related QuestionsWhat concerns are raised by opponents of food irradiation?
Food IrradiationThe term irradiation often evokes fears of nuclear radioactivity and cancer among consumers. The process seems frightening because it is powerful and invisible. Consequently, questions and concerns exist, particularly about the safety or wholesomeness of irradiated food. Here are some commonly asked questions.
Related QuestionsQ.: What foods have the Food & Drug Administration (FDA) approved for irradiation?
Organic Madness: About Us - FAQA.: The foods that the FDA have approved for irradiation include wheat, flour, red meat, poultry, pork, fresh shell eggs, vegetables, and spices as well as refrigerated and frozen uncooked meat, meat by-products, and certain other food products made from meat.
Related QuestionsWhich foodborne diseases could be prevented with irradiation?
Disease Listing, Food Irradiation | CDC Bacterial, Mycotic D...Treating raw meat and poultry with irradiation at the slaughter plant could eliminate bacteria commonly found raw meat and raw poultry, such as E. coli O157:H7, Salmonella, and Campylobacter. These organisms currently cause millions of infections and thousands of hospitalizations in the United States every year. Raw meat irradiation could also eliminate Toxoplasma organisms, which can be responsible for severe eye and congenital infections.
Related QuestionsWhat is the actual process of irradiation?
Disease Listing, Food Irradiation | CDC Bacterial, Mycotic D...Three different irradiation technologies exist, that use three different kinds of rays: gamma rays, electron beams and x-rays. The first technology uses the radiation given off by a radioactive substance. This can be either a radioactive form of the element cobalt (Cobalt 60) or of the element cesium (Cesium 137). These substances give off high energy photons, called gamma rays, which can penetrate foods to a depth of several feet.
Related QuestionsHow does irradiation affect foods?
Disease Listing, Food Irradiation | CDC Bacterial, Mycotic D...The foods are not changed in nutritional value and they are not made dangerous as a result of the irradiation. The high energy ray is absorbed as it passes through food, and gives up its energy. The food is slightly warmed. Some treated foods may taste slightly different, just as pasteurized milk tastes slightly different from unpasteurized milk. If the food still has living cells, (such as seeds, or shellfish, or potatoes) they will be damaged or killed just as microbes are.
Related QuestionsHow do you measure the amount of irradiation used?
Disease Listing, Food Irradiation | CDC Bacterial, Mycotic D...The dose of irradiation is usually measured in a unit called the Gray, abbreviated Gy.. This is a measure of the amount of energy transferred to food, microbe or other substance being irradiated. 10 kiloGrays, or 10,000 Grays, is the same as an older measure, the megaRad. A single chest X-ray has a dose of roughly a half of a milliGray (a thousandth of a Gray). To kill Salmonella., fresh chicken can be irradiated at up to 4.
Related QuestionsHave there been any accidents involving irradiation facilities?
Disease Listing, Food Irradiation | CDC Bacterial, Mycotic D...Medical sterilization facilities have been operated in this country for more than 30 years, without a fatal accident. Over 100 such facilities are currently licensed, along with at least that many medical radiation treatment centers, and bone marrow transplant centers (which also use Cobalt 60 to irradiate patients). No events have been documented in this country that led to exposure of the population at large to radioactivity.
Related QuestionsHow does irradiation affect disease-causing microbes?
Disease Listing, Food Irradiation | CDC Bacterial, Mycotic D...When microbes present in the food are irradiated, the energy from the rays is transferred to the water and other molecules in the microbe. The energy creates transient reactive chemicals that damage the DNA in the microbe, causing defects in the genetic instructions. Unless it can repair this damage, the microbe will die when it grows and tries to duplicate itself.
Related QuestionsWhich foods have been approved for irradiation in the United States?
Disease Listing, Food Irradiation | CDC Bacterial, Mycotic D...A variety of foods have been approved for irradiation in the United States, for several different purposes. For meats, separate approval is required both from the FDA and the USDA.
Related QuestionsWho makes sure that the irradiation facilities are operated safely?
Disease Listing, Food Irradiation | CDC Bacterial, Mycotic D...The effectiveness of the treatment in eliminating pathogens will be regulated as a food safety process, by either the USDA or the FDA, often in concert with State authorities, just as is the case now for milk pasteurization or retort canning. The safety of operations of irradiation facilities is regulated separately. This requires extensive worker training, supervision, and regulatory oversight. Facilities using radioactive sources are regulated by the Nuclear Regulatory Commission (NRC).
