Well now,we might have two parts,or maybe three,of different discussions.
I'm thinking this thread is mostly about how to turn out some chicken that looks and tastes acceptable to our family and friends.
Now,the added benefit is they don't get food poisoned.
There is" nope you probably won't die from it".
There are good chefs ,that hot cook chicken about 450º-500º,until their eyes just quit blinkin'.
.
That carryover, external heat will haul dark meat from in the 150º s to about 175º,where it is still pretty moist.
I'm thinking,maybe 160º, for around a half minute,will keep you from dying, from most things,unless they have converted to a chemical.
This being why you don't leave that butt in the OK sun, in the car,all afternoon and figure cooking it enough, ought to kill most critters.
This be where the old, above 35º-40º and below 135º-140º for four hrs, ought to go to the landfill.
Then there is visually and texure[mouth feel] appealing,which often takes a few more degrees.
Also, there is the yardbird industry figurin' out you could get a chick to market size -this month-whether it's bones have developed and sealed, or not.
The packer can also freeze it some,but not too much,and it is still sorta fresh.
Now Smokin' will probably point out to you,how disappointed a comp cook can get,when he's paid about $2,000 in total expenses, been on the road for five days in his shiny big truck,haulin' that fancy custom 36 ft Featherlite trailer,to that big invitational, we all want to go to,and sees the KCBS rep walking back towards you with your chicken entry.
He opens that box,to show the partially sealed bone,with the blood vein running bright red along it.
Now the up side of that DQ,is you can sit right down and start drinkin that Jack and Coke,'cause its all over but the shoutin' and the cryin'.
That is why hot chicken cooks,sometimes, let their chicken parts set out 30-45 mins,to warm up a little.
Also,vendors,etc, hate to turn out well cooked chicken,and see the trash barrels filled with "undercooked" chicken.
