Food irradiation - issues of concern
|Contributions||London Food Commission.|
Food irradiation is not a new technology. Irradiation of fruits and vegetables decreases the risk of pathogens and extends shelf life. But as discussed in Chapter two, public concerns about the safety of irradiated food, fueled in part by a lack of consumer education, limits its . Why is food irradiated? Is irradiation used for non-food products? Are irradiated foods being sold now? How can I tell if food has been irradiated? Does irradiated food cost more? Are consumers buying irradiated food? Who endorses the use of food irradiation? Why not just cook food thoroughly to kill bacteria?
Food-associated diarrheal disease is a major problem in the United States. One approach offered as virtually a panacea is food irradiation. Irradiating our food would have some unequivocal benefits, but there are some important unresolved issues that must be addressed before we commit our society to a technology that could be harmful. Food and Water Watch officials point out that the same energy that kills bacteria can also alter the chemical structure of food. The group's concern is that carcinogens are created - something that Executive Director Wenonah Hauter warned about in her book "Zapped: Irradiation and the Death of .
Food irradiation standards support international trade. Irradiation has become widely accepted as a proven and effective post-harvest treatment to reduce bacterial contamination, slow spoilage and maintain food quality. It prevents premature sprouting and ripening, and acts as a phytosanitary treatment to control insect pests in fruits and. Irradiation, as a method for food preservation, has been studied for more than 30 years. This discussion focuses on this most recent method for the preservation of food with particular emphasis on its effects on the safety, more» nutritive, and aesthetic values of the food preserved by irradiation.

Ideas for inclusion
Food Irradiation focuses on the fundamental aspects and applications of food irradiation. It summarizes efforts to establish the wholesomeness of irradiated foods, and it discusses the nature of ionizing radiation, as well as its interaction with matter, the biological effects it induces in living organisms associated with food such as raw fruits and vegetables, and the application of these Book Edition: Food irradiation - issues of concern book.
irradiation treatment, the absorbed dose, and at least some concern for the benefit- to-risk ratio. In this manuscript the benefits of food irradiation in context with the risks that may be associated with the treatment will be discussed. Four criteria are generally recognized as necessary for an irradiated food toCited by: Food irradiation is an efficient technology that can be used to ensure food safety by eliminating insects and pathogens to prolong the shelf life, among others.
In most of the cases, the process could be applied to fresh or frozen products without affecting the nutritional value and sensory quality of treated foods.
Examples include changes to the taste, texture, smell or shelf life of a food. Published research on irradiated foods reveals that irradiation does change, and can actually ruin, the flavor, odor, appearance and texture of food. Such research repeatedly finds that irradiated foods smell rotten, metallic, bloody, burnt, grassy and generally off.
Food Irradiation: A Gross Failure. Download the Report The strange, sickening impacts on the smell, taste, color, and texture of food exposed to radiation.

The presence of parasites, some micro-organisms, yeast and moulds are also the source of problems sometimes directly or indirectly caused by toxin formation in food products.
Irradiation alone or combined with others processes, can contribute to insuring food safety to healthy and compromised consumers (pregnant mothers, immuno-compromised AIDS. Irradiation also causes stunted growth in lab animals fed irradiated foods.
An important study linked colon tumor promotion in lab rats to 2-alkylcyclobutanones (2-ACB’s), a new chemical compound found only in irradiated foods. The FDA has never tested the safety of these byproducts. The one realistic concern with food irradiation concerns the cobalt source.
This has to be transported to the irradiation facility and in theory accidents can happen along the way. But current methods of transporting radioactive materials are very sophisticated and accidental release of radiation is extremely unlikely.
The Dangers Of. Food Irradiation. From Dr. Gayle Eversole, PhD, ND. Originally reported on in More on the Problems with Food Irradiation.
Food irradiation exposes food to the equivalent of 30 million chest X-rays. Irradiation creates new chemicals in foods. Food irradiation (the application of ionizing radiation to food) is a technology that improves the safety and extends the shelf life of foods by reducing or eliminating microorganisms and insects.
The Center for Food Safety announced the release of Fatal Harvest: The Tragedy of Industrial Agriculture, a book that takes an unprecedented look at our nation’s destructive farming practices, and offers positive solutions in support of a new vision of farming.
A brief background of the food irradiation issues leading to these conclusions is given. fear that irradiated food is radioactive. Another concern is that irradiated food contains free. Food Irradiation: Principles and Applications provides a comprehensive, up-to-date account of food irradiation principles, effects, applications, and limitations, including global regulatory issues.
Issues surrounding use, safety, and exposure to radioactive materials are often promoted as a concern relative to food irradiation, while similar concerns have not been major issues pertaining to the use of irradiation to sterilize medical equipment and other healthcare products (Derr, ).
Irradiation, which involves exposing food briefly to radiant energy, can reduce or eliminate microorganisms that contaminate food or cause spoilage. So far, only limited quantities of irradiated foods—spices, herbs, dry vegetable seasonings, and some fresh fruits, vegetables, and poultry—have been available in the United States.
4. It eliminated warning signs of food spoilage There is concern that irradiation will make it hard to tell whether or not food has gone bad because that certain element has been stripped before it landed in someone’s grocery basket.
Normal indicators such as smell or mold are destroyed thanks to irradiation. Consumer concerns associated with irradiated food include worries about the long-term effects of consumption, the nutritional quality of food, the danger of working at or living near an irradiation facility, and concerns about cancer due to the association of irradiated food with other radiation-related technologies such as nuclear power (Henson, ; Bruhn, ).
The issues of concern for consumers, activists and government are discussed in an effort to understand the benefits of food irradiation as a food safety measure.
Food safety is a global issue with paramount environmental and public health endeavor. The concern for ensuring food safety can be illustrated by the extent of food-borne illnesses around the world.
Even with a well-established food inspection and supply system in Food irradiation technology typically uses electron beam and ionizing. The book also highlights some aspects of food irradiation that have potential significance in commercial usage, including consumer attitudes, costs, facilities, and safety.
Organized into 15 chapters, this volume begins with an overview of ionizing radiation and its biological effects, the basics of radiation chemistry, and radiation chemistry. The use of high energy irradiation to kill microbes in food was evaluated in this country as early aswhen scientists at the United States Department of Agriculture reported that it would effectively kill trichinae in pork ().Irradiation has become a standard process used to sterilize many consumer and medical products, from adhesive strips to surgical implants.P.B.
Roberts, in Encyclopedia of Food Sciences and Nutrition (Second Edition), Role of International Organizations. International organizations such as the Food and Agriculture Organization (FAO), the World Health Organization (WHO), and the International Atomic Energy Agency (IAEA) support the irradiation processing of food as a contribution to safe and secure food supplies.One of the real concerns about food irradiation is that it might be used to mask poor sanitation practices in food production.
For example, instead of taking measures to clean up and sanitize production facilities, food irradiation can be used to mask fecal contamination of meat products and poultry.
