Disadvantagesit may not kill all bacteria on an object.it can be very harmful - standing in the environment where objects are being treated by irradiation could expose people's cells to damage and mutation.
What are the effects of irradiation?
When you irradiate food, you produce an effect on microorganisms due to their effects on DNA and cell membranes. Photons, electrons, or x-rays strike the cell membranes and the DNA, damaging both. In plant cells, DNA is not required for reproduction, so damage to DNA is irrelevant.
Why is irradiation used?
Irradiation is an effective form of food preservation that extends the shelf life of the food and therefore reduces the spoilage of food. The process also benefits the consumer by reducing the risk of illnesses caused by foodborne diseases.
Do you think food irradiation is safe in our health Why?
Food irradiation does not make food radioactive. Food irradiation reduces or removes pathogens, such as bacteria and molds, that spoil food and cause food poisoning and other illness. For example, irradiation can kill Escherichia coli, Campylobacter and Salmonella bacteria.

What is a benefit of food irradiation? b. Irradiation eliminates organisms that cause foodborne illnesses, such as Salmonella and E. coli.
How does food irradiation work?
During irradiation, energy passes through food much like a ray of light passes through a window. This energy destroys most of the bacteria that can cause disease, yet allows food to retain its high quality. Irradiation pasteurizes food by using energy, just as milk is pasteurized using heat.
Can organic food be irradiated?
Can organic foods be irradiated? Happily, no. Just as opting for an 'organic' label means the food cannot be genetically modified, foods labeled 'organic' cannot be irradiated.
How does radiation preserve food?
The radiation destroys food-borne bacteria. Radiation is measured in units called rads. The FDA allows exposure of up to 100,000 rads for already approved foods. At this level, gamma rays penetrate the food and kill bacteria and other infectious organisms by preventing the organisms from dividing and growing.

Does irradiation sterilize food?
While it need not sterilise the food – it is still necessary to handle and cook the food properly - irradiation maintains it as “clean” and inhibits spoilage, making it possible to keep food longer, while ensuring a higher level of safety and quality.
Is irradiating food the same as heating food?
Irradiating food has the same benefits as when it is heated, refrigerated, frozen or treated with chemicals, but without changing the temperature or leaving residues. The technique controls spoilage and food-borne pathogenic micro-organisms or insect pests without significantly affecting taste or smell.
Why sterilize food?
Sterilized foods are useful in hospitals for patients with severely impaired immune systems, such as patients with AIDS or undergoing chemotherapy. Foods that are sterilized by irradiation are exposed to substantially higher levels of treatment than those approved for general use.
What is the FDA requirement for irradiated foods?
The FDA requires that irradiated foods bear the international symbol for irradiation. Look for the Radura symbol along with the statement “Treated with radiation” or “Treated by irradiation” on the food label. Bulk foods, such as fruits and vegetables, are required to be individually labeled or to have a label next to the sale container.
Why do we need to store irradiated food?
Irradiated foods need to be stored, handled, and cooked in the same way as non-irradiated foods, because they could still become contaminated with disease-causing organisms after irradiation if the rules of basic food safety are not followed.
How does ionizing radiation affect food?

Delay of Sprouting and Ripening – to inhibit sprouting (e.g., potatoes) and delay ripening of fruit to increase longevity.
What is gamma radiation?
There are three sources of radiation approved for use on foods. Gamma rays are emitted from radioactive forms of the element cobalt (Cobalt 60) or of the element cesium (Cesium 137). Gamma radiation is used routinely to sterilize medical, dental, and household products and is also used for the radiation treatment of cancer.

What is Food Irradiation?
Food irradiation is a process in which food products are exposed to a controlled amount of radiant energy to kill harmful bacteria such as E. coli 0157:H7, Camplybacter, and Salmonella. The process also can control insects and parasites, reduce spoilage, and inhibit ripening and sprouting.
What are the Benefits?
Food is irradiated to make it safer by destroying harmful bacteria, parasites, insects, and fungi. Irradiation does not destroy all disease-causing organisms, so perishable irradiated foods must still be kept in the refrigerator or freezer. Neither does it cook foods, so irradiated meat is still not safe to eat raw.
Are Irradiated Foods Safe?
The Food and Drug Administration (FDA) has evaluated the safety of irradiation over the last 50 years and has found it to be safe. Irradiation produces fewer changes in foods than those caused by cooking.
How Does Irradiation Work?
Food is packed in containers and moved by conveyer belt into a shielded room. There the food is exposed briefly to a radiant energy source. The amount of energy used depends on the type of food. Energy waves passing through the food break molecular bonds in the DNA of bacteria, other pathogens, and insects.

Not widely yet. Some stores have sold irradiated fruits and vegetables since the early 1990s. Irradiated poultry is available in some grocery stores and on menus of a few restaurants. Some meat products such as ground beef have been available in South Carolina markets since early 2002.
Do Irradiated Foods Cost More?
Irradiated products cost slightly more than conventional foods: about two to three cents more per pound for fruits and vegetables, and up to 25 cents more per pound for meat and poultry products. These costs may be offset by advantages such as keeping a product fresh longer and enhancing its safety.
What are the benefits of irradiating food?
1. It prevents food-borne illness. Through irradiation, organisms that cause food-borne illnesses such as Salmonella and Escherichia coli are effectively eliminated. 2. It helps preserve food. Irradiation destroys and inactivates organisms that cause food to spol and decompose.

Food irradiation is a subject that has created a lot of debate over the years. Anything with the term “radiation” in it is seen as potentially harmful, even though people are exposed to radiation every day. The goal of food irradiation is to create a safe food supply so that people are able to have confidence in the foods they’ve eaten. There may be some additional advantages beyond safety and some disadvantages to consider as well, so here is a look at the pros and cons of food irradiation in greater detail.
Can radiation kill everything in food?
1. There is no guarantee that it can kill everything in the food.#N#Some organisms that can be found in food are known to be resistant to radiation. Others are naturally designed to be difficult to kill and the light levels of radiation put into the foods does nothing to affect their overall life span.
