Hello,
As far as salmonella is concerned, you are more likely to get it from spinach than the raw chicken, or any other meats. (It can also be in processed dog food). I also asked my vet when was the last time they treated a dog for salmonella and they couldn't give me an answer. All of my dogs good is human grade from the market . I'm very thorough with my clean up, and he never eats in the house. Outside on the deck or in the garage if the weather is bad.
Again, it works for me and others would disagree and that's ok.
