- Irradiated Food: Safe or Not?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: I am interested in learning more about a new process that sounds
- like it uses radioactivity to preserve food. It seems that there is a lot of
- controversy about this and if it is safe. I would like you to settle this for
- me, once and for all. Then I will know if I should buy foods that are treated
- by this method. Thank you for your help.

- ANSWER: I wish I could "settle" this controversy for you, but it is not as
- simple as you might think. To start with, the process you are interested in
- is called "irradiation". Foods are exposed to gamma rays, which can destroy
- some germs, like salmonella, and other disease producing bacteria often found
- in meats and poultry. The same process can rid produce of insects and delay
- ripening, which allows the veggies to remain on the shelves for longer periods
- of time without spoiling.
- The method is not entirely new, for the same technique has been used to
- sterilize medical supplies, such as bandages and syringes, for some time.
- While the materials are exposed to the gamma rays for sufficient time to
- become sterile, the bandages and other materials do not become radioactive,
- nor in any way dangerous to the consumer.
- Sounds like a great idea, say those who feel that this treatment of food
- products may reduce the use of toxic chemicals, and reduce the number of food
- borne illnesses. However the opponents point to the fact that irradiation may
- cause changes in the chemical structure of the molecules that could eventually
- cause cancer. Possible? Yes, but there is still no scientific evidence to
- back up the fear. Another criticism of the process is the fact that
- irradiation treatment can reduce the nutrients in the food by 10-15 percent.
- But then so do other methods of food processing, including ordinary cooking.
- The truth is that irradiation can not be used on all types of food, and
- is no cure-all that will solve all the problems in food processing. It can
- not be used on milk or dairy products, as it produces unpleasant odors, and
- can actually accelerate the decay of fresh fruits that contain high water
- content, such as peaches. While irradiation does disrupt some of the chemical
- bonds in treated food (6 out of every 10 million or .00006 percent), the
- percentage is too small to create any harmful effects. Certainly additional
- research is always needed to fully satisfy all who have doubts, but on the
- basis of currently available data, it looks like irradiation will be a useful
- tool for food processing in the future.
