Yes, cooking kills salmonella, as well as any other germs and bacteria. The high heat kills them off. Bacteria thrive in high heat, but after a certain point it begins to kill them. I'm not sure how fast though...I doubt that just plungeing your chicken into a vat for boiling water for a minute or two will do the job (although if you intend to actually cook it there, for a while, it should work fine...although boiled chicken doesn't sound too appealing)...but it it's cooked properly, you shouldn't have to worry.
