well for one thing people who feed RAW DONT feed muscle meat alone. you feed the Raw meat including the bone, and you feed organ meats and veggie mush to simulate the nutrients that would be found in the prey body. many people also feed the whole animals, there is a place that sells whole animal patties(the entire animal gorund into patties) a dog and cats digestive tracts are also WAY shorter then a humans, while its true that they can get e-coli and salmonella, its far easier for a human to get it then a dog or a cat, because the bacteria does not sit there for any amount of time. to be honest its easier to get e-coli or salmonella from kibble, why? because kibble sits in the animals digestive system much longer then it should, while things like RAW meats and other natural foods pass right through, that is why you cant feed the 2 together without some trouble, kibble takes nearly a full day to fully digest while natural foods only takes a few hours or even minuts. the problem with cooking the food is that while it kills the bad stuff that they are unlikley to get in the first place, it also kills all the good nutriets, and kind of defeats the purpose.
