Is Food Irradiation Safe?

It seems like every time we turn on the news, there is another story about an outbreak of food poisoning somewhere in the country. According to the Centers for Disease Control (CDC), food-borne diseases cause approximately 76 million illnesses, 325,000 hospitalizations, and 5,000 deaths in the United States each year.

To help combat this issue, the CDC, the Food and Drug Administration (FDA), the World Health Organization, the American Medical Association, and many other health and safety experts have endorsed food irradiation, which promises to reduce significantly the risk of food-borne illness from Salmonella, E coli, and other dangerous pathogens that may be lurking in our produce or meat. But is food irradiation safe?

What is Food Irradiation?

Food irradiation destroys disease-causing microorganisms and insect invaders by briefly exposing them to large doses of ionizing radiation, such as gamma rays or electron beams, which disrupts and destroys the organism’s DNA. Irradiation does not make the food radioactive, anymore than an xray makes you radioactive or an airport luggage screener causes your baggage to glow.

In addition to preventing disease, irradiation reduces spoilage bacteria, insects and parasites, and in certain fruits and vegetables it inhibits sprouting and delays ripening. For example, irradiated strawberries stay unspoiled up to three weeks, versus three to five days for untreated berries.

Irradiation is not a substitute for proper food manufacturing and handling procedures. But the process, especially when used to treat meat and poultry products, can kill harmful bacteria, greatly reducing any potential hazards.

Which Food is Irradiated?

The FDA has approved irradiation of meat and poultry and allows its use for a variety of other foods, including fresh fruits and vegetables, and spices. However, because of consumer perceptions, irradiation has largely been restricted to spices and other dried vegetable products.

The Radura Symbol

Federal rules require irradiated foods to be labeled with the “radura” symbol to distinguish them from non-irradiated foods. While any food you buy in the supermarket will be labeled, there are no requirements for restaurants, cafeterias, or similar food sources.

Is it Safe?

Food irradiation remains a very controversial topic. There have been concerns raised by some groups that the chemical products created in the food during the irradiation process may be harmful. However, there is no current scientific evidence to support this claim, and many of these chemicals are the same or similar to those created during other food processing techniques, such as cooking or canning.

There can be a small loss of nutrients with irradiated foods, but usually no more so than with other food processing methods And, if knowing that your produce is safe causes you to eat more of it, this effect may be outweighed.

Critics also point out that it may be more cost-effective, and safer, to clean up the problems with the food industry that are causing these contamination problems in the first place. We’re all for that. But there is always risk of contamination in food production, and it only takes one bad processor to cause a serious outbreak.

Irradiation is allowed in nearly 40 countries and is endorsed by many leading health organizations. The process has been around for decades and the scientific evidence has not shown any ill-effects to humans from eating irradiated foods. With 5,000 estimated food-borne illness deaths per year, including a large percentage who are children, is not having irradiation safe?

After a semester of doing research on the topic of food irradiation, I am still very much indecisive on whether or not it is safe. Though it is true that it does kill off harmful bacteria such as E colie and Salmonella, there have been numerous studies claimed that show some harmful side effects in cats. Some of these side effects included movement disorder, loss of vision, and even paralysis. If I were to choose a side, I would lean more towards the safe side, merely because most of the studies claimed to have been done aren’t as reliable as most of the other facts.

I hope it's safe, it

From Dan on August 27, 2010 :: 12:23 am

I hope it’s safe, it sounds pretty scary.  If you think we are eating food every day that is partially radiated it might in long term be bad for us.

The Meat Industry says Irradiation it's Safe... Where's the Proof?

From Briana on March 08, 2012 :: 8:04 pm

Food irradiation has never been tested for safety and it destroys the vitamins A, B-1, C, K and E. With this technology, the slaughtermen no longer have to worry about avoiding cutting the intestines which results in feces all over your meat. Irradiation kills bacteria and other micro-organisms, but now your hamburgers are covered in feces, urine and puss. Even though labels have to be put on the food in the grocery store, labeling is not required for foods in restaurants and school lunch programs. Therefore, when your children are eating lunch at school, they are really acting as the meat companies guinea pigs in an experiment that could be potentially dangerous. Whatever you find on the internet is going to be lies produced to you by yours truely, the meat companies. If you want to learn more about this, get the 10th Edition of The Food Revolution by John Robbins.

There have been hundreds of

From Josh Kirschner on March 09, 2012 :: 9:44 am

There have been hundreds of scientific studies going back decades that have demonstrated the safety of irradiated foods and its negligible impact on nutritional content, which is why the CDC, WHO the AMA and many other leading health organizations support it.

Irradiating food doesn’t eliminate the need for slaughterhouses to maintain sanitary conditions any more than pasteurizing milk eliminates the need for dairies to do so (would you advocate eliminating pasteurization for the same reason?). So the hyperbole about feces, urine and puss in your food is just that. But in the event of contamination, irradiation can prevent people from getting sick.

Irradiation can also be used for fruits and vegetables to prevent E-coli outbreaks as we’ve seen in the past from spinach and tomatoes. So the benefits go well beyond meat safety.

Irradiated Foods reduce Thyroxin Formation

From Ashok T Jaisinghani on June 09, 2016 :: 4:23 pm

★★★IRRADIATED FOODS cause DRASTIC REDUCTION in THYROXIN FORMATION★★★


     Irradiation of foods is done for reducing spoilage by killing the pathogenic bacteria and harmful insects. Irradiation is also used for preventing the sprouting and ripening in vegetables and fruits. 


     Irradiation of foods causes massive losses of Vitamin B1 and Vitamin C, which can be as high as 80 per cent to 90 per cent! The regular consumption of such foods can cause SEVERE CONSTIPATION, which cannot easily be relieved even by the regular use of laxatives. Can even the highly experienced doctors understand the real reason for such SEVERE CONSTIPATION? The SEVERE CONSTIPATION must be the result of eating IRRADIATED FOODS, which must be destroying Vitamin B1, Vitamin C and other biochemicals also within the bodies of the persons who consume such foods, which can have low-level RESIDUAL RADIATION! 


     The REGULAR consumption of   IRRADIATED FOODS drastically REDUCES the formation of THYROXIN by preventing the utilization of IODINE. As the thyroid gland becomes extremely SLUGGISH, and there is a massive deficiency of thyroxin, the CONSTIPATION also becomes EXTREMELY SEVERE in the affected persons. 


     Besides HYPOTHYROIDISM, this chronic constipation due to the IRRADIATED FOODS can be associated with polyneuritis (pain in nerves), edema, high blood pressure, high levels of fat and cholesterol in the blood, obesity, heart disease, headaches, sleeplessness, mental depression, baldness, chronic fatigue, non-insulin-deficiency diabetes (NIDD), leukemia, tumors and cancer. 


     The REGULAR consumption of IRRADIATED FOODS and DRINKS can also cause ARTHRITIS. The harmful effects of IRRADIATION can make the bones weak and even cause pain in the joints. Due to the SCURVY and BLEEDING of GUMS, caused by the massive destruction of Vitamin C, there can also be a LOOSENING of the TEETH, which can be lost. Even WHOLE UNDAMAGED teeth can just get loose and fall out from their sockets in the jaw bones due to the harmful effects caused by the regular consumption of IRRADIATED FOODS and DRINKS. Otherwise, why should the teeth, which appear to be quite healthy, become loose and fall out? I have myself lost 2 WHOLE TEETH in their original shape and size, which just loosened and came out! I have kept the 2 INTACT teeth in a glass bottle, as I can show them to others when necessary. 


     Even the fiber-rich foods made from multigrains can become EXTREMELY CONSTIPATING after they are treated with IRRADIATION. The IRRADIATION causes MASSIVE DESTRUCTION of Vitamin B1, Vitamin C and other nutrients not only in such foods, but also in the bodies of people who consume such foods, which continue to have low-level RESIDUAL RADIATION!


     Almost all of the packed foods and drinks, which have shelf lives of many months, or even a couple of years, are HIGHLY IRRADIATED items. Only a few days back, I realized that I was suffering from the TOXIC EFFECTS of IRRADIATION due to eating ROTEES (unleavened bread) prepared from the multigrain flour containing about 90% whole wheat flour, the packet of which I had bought from a big MALL. Somehow I have just managed to survive. Now, I prefer to buy many food items that are available LOOSE from the local grocers, rather than buy the PACKED grains and flours from the POSH MALLS, where HIGHLY IRRADIATED items are sold in packages. 


     IRRADIATION of FOODS and DRINKS must have already caused the PREMATURE DEATHS of MILLIONS of PEOPLE all over the world. 


     Ashok T Jaisinghani.
