Julius of Friends of the Earth. This, in turn, might require development of additional energy resources, possibly including geothermal. If one attempts to tabulate the tens of thousands of Salmonella, Campylobacter, Yersinia, Listeria and Escherichia coli foodborne disease outbreaks related to poultry and meat, the totals exceed millions of human illnesses. Cesium-137 is one of the most dangerous radioactive by-products of nuclear weapons production. Other food sanitation technologies such as high pressure, pulsed light, and ozone treatment are currently under development and may provide benefits similar to irradiation without the drawbacks. Not only is food expensive, but some carry the risk of causing harm to those who eat it. Other examples of unsafe practices at irradiators include incidents at the Isomedix facility in New Jersey, which was determined by the Nuclear Regulatory Commission to have flushed radioactively contaminated water into city sewers in 1974.
Check out our favorite online tools geared to get you the kind of visibility advertisers dream of, from educational courses to optimizing apps. It extends the shelf life of food. If irradiation is a proven technology as proponents claim and the market for irradiated fruit is solid as proponents claim , there should be no impediment to the private sector raising the capital needed for an irradiation facility, either by putting up the money themselves, by attracting equity investors, or by borrowing the funds. Allegedly, it makes tomatoes mushy. Safety and nutritional adequacy of irradiated food, Geneva: World Health Organization Distribution and Sales, 161 pages, 1994. As a result, many public health and government officials have begun a campaign to promote the increased use of irradiation on our food.
Source s :Conclusions By Bill Marler -Food. Immune Deficiency Benefits Those who suffer from a disease that depresses the immune system, which can occur through meds or the disease itself, can become ill from the most general food contaminants. Irradiated food must therefore be handled with even greater care in homes and restaurants. This reduces the incentive to clean up sloppy food processing operations - the industry is provided with a 'quick fix' as an alternative to dealing with the sources of the problem. Right now there are many unanswered questions about the long term safety of irradiation.
Labelling of irradiated foods If a food has been irradiated or contains irradiated ingredients or components, it must be labelled with a statement that the food, ingredients or components have been treated with ionising radiation. Divorce papers online free 29-6-2018 · Free Online Library: Conclusions By Bill Marler -Food. Yet how many of us daily drive in cars potential bombs , cook over gas flames or campfires, or light cigarettes with matches all potential torches? Irradiation is the process of treating food and other consumer products with gamma rays, x-rays, or high voltage electrons to kill potential harmful bacteria and parasites, delay sprouting, and increases shelf life. The containment and transportation of the radioactive substances are fairly secure. There were no toxic products formed than might normally be found in a single charbroiled hamburger. Pros and Cons of Food Irradiation There have been many views on Food Irradiation and its safety. How many thousands of deaths and illnesses could have been prevented if we public health authorities had implemented food irradiation and educated the public as to its benefits we will never know.
Food irradiation is a processing and preservation technique with similar results to freezing or pasteurisation. It prevents food-borne illness Through irradiation, organisms that cause food-borne illnesses such as Salmonella and Escherichia coli are effectively eliminated. . Section 107, this material is distributed without profit to those who have an interest in using the included information for research and educational purposes. In other words, the radiation that just one papaya must receive is many times that which can kill a person. There is also a trend towards increased commercialization of irradiated food.
No Promises One of the problems with food irradiation is that there is no definitive way of killing all of the organisms that can come into contact with our foods. Food irradiation has remedied the scarcity of food but it might cause more harm than good. Gamma rays and X-rays penetrate skin easily. These include chromosomal abnormalities, rare cancers, and even premature death. Impaired or weakened immune system is more vulnerable to these microbes. It does not replace the need for correct food handling practices in industry and in the home. The strength of a radioactive source or electron beam used in an irradiation facility is many millions times greater than that used in medical equipment.
Is organic food more nutritious than conventional food? Since the production of cobalt -60 does require the use of nuclear reactors, one cannot truthfully say that its production does not generate radioactive waste. To do this, a legal fiction was created that ionizing radiation used to treat food is a food additive. There is no question that there is a great deal of controversy on the subject of food irradiation advantages and disadvantages. Among the first public health leaders to speak out on the importance and value of food irradiation was James Mason, M. It has the potential both of disinfesting dried food to reduce storage losses and disinfesting fruits and vegetables to meet quarantine requirements for export trade. Without such a label, there is no telling how a particular food has been processed, packaged or even produced and shipped.
That same year, 1958, food irradiation was downplayed by the U. Here is what John Gofman, M. Several market testing and consumer acceptance studies have been carried out on food irradiation in recent years. Foods that have been irradiated come with a Radura label, allowing consumers to make a choice to buy or avoid irradiated food products. Gamma rays destroy the majority of bacteria and fungi in the food to sanitize the product of germs, making it safe for patients in the hospital to consume because they need to be surrounded by a sterile environment. Each modern food-processing advance pasteurization, canning, freezing - produced criticism.
Still, a 20 percent to 80 percent loss is not uncommon. Efforts to solve the problem have been proven ineffectual. It has become a symbol of hope in the battle against foodborne illnesses, but like all symbols, it can have a different, much darker meaning. Lack of harmonization of regulations among the countries which have approved irradiated foods hampers the introduction of this technique for international trade. The extension of human life and well being is attributable to good public health practices, immunization of all children and adults, chlorination of potable water, sewage disposal of human and industrial waste, and food hygiene, including pasteurization.
