As stated earlier, the lethality of salmonella is a function of both temperature and time. This has been mentioned various times. Here is an old post by Knucklhed:

Let me ask this question though, would you consider chicken kept at 137 for an hour to be:
A) Lethal - WTH are you trying to do to me man????
B) Just right! Bring it on, I'm hungry fo' that!

FDA says... Good to go! What???? AYFKM???!!!! (Are you freaking kidding me??)

Now, I'm not saying that the taste & texture will be what you want, but - technically, safe.


From USDA.gov - pages 5 - 16: http://www.fsis.usda.gov/OPPDE/rdad/...try_Tables.pdf

If you're cooking the chicken at fairly low temps, then you're probably not going to need to be resting that chicken very long. This definitely supports Harry Soo's chicken. It also suggests very strongly that most salmonella problems are due to cross-contamination, rather than cooking temps.

As Landarc mentions, the high cooking temperatures required for chicken are regional. They are the result of our high throughput chicken processing. In many other countries, chicken is cooked rare to medium rare. Bob mentions Asian countries, but it is also true of Slavic countries.
