You can probably chill a little on your disinfectant routine. Then again, you have to do what makes you comfortable.
If I cut up raw chicken or something, I just wash the knife and cutting board with hot water (hottest it can be like you) and a soapy sponge , then set it out to dry. That's it. It's the same sponge I use on the other dishes, I just give it an extra rinse out with the super hot water when I'm done. I don't clean the sink out after (unless I am about to put a bunch of other food like vegetables in there).
No salmonella or whatever in my household so far.
