Ok, as a scientist I feel a need to respond to that article you posted Kara.
First off, let me comment on the abstract that was given as "proof" that irradiation is bad for animals through mouse testing. The level of irradiation used on the food given to those mice is so above and beyond what is legal, it doesn't even make any sense. Do you know that even using 10KGy of irradiation is the highest amount of radiation currently being used on any food items? Anything above that would be a complete waste as bacteria are killed at a level of 1-4 KGy. There is absolutely no way anyone is using levels of 400 KGy to kill off bacteria in pet food or human food.
Just think about it this way, if you stay out on a really hot day for 10 minutes your chances of getting a sunburn are slim to none. However, if you stay out for 4 hours on the same hot day, you are pretty much asking for a sunburn. It's hard for you to say that just because 4 hours of sun will give you a burn then 10 minutes of sun is bad for you. That's pretty much the conclusion that person who wrote the article is coming to.
If anyone were irradiating dog food to such an extent, all of our pets would be dying left and right by the thousands, not the few deaths that have been occurring. I seriously doubt that irradiation is what is causing all of these pet food recalls and problems.
Also, free radicals are very scary things and can cause all sorts of mutations in your DNA. However, notice that even in the abstract listed above (where they irradiate food way above and beyond what is actually done) they mention that although there were growth problems (loss of weight, etc.), they found no mutations in any of these mice. There is no way that free radicals were the cause of these growth problems because if they were, mutations would be abundant in these mice. Instead, if anything, it was probably the loss of nutrients in the food from the high irradiation that caused the weight loss and subsequent death in these mice.
Sorry for the long post, but I just had to put my 2 cents in.
