Doggy digestion is much different then people digestion. The chances of your kids getting some type of bacteria from their food are slim. I feed my girls raw, and haven't given it a second thought. And since I buy chicken and such from the grocery store, their chicken isn't always the freshest, sorry to say.
Raw has done wonders for my girls. My senior rottweiler has more energy then she has had in years, sheds less and looks fabulous.
