Because 159 was too low, and 161 was too high....
Hey, you opened the door....
Imagine this: You are using your thermometer, but one day you discover it reads high.
Holy Moly! You been eating 154 degree processed Jerky!
But wait, you are still alive. Hallelujah!
There needed to be a "standard", a target temperature.
160 filled the bill. Hot enough to kill bad bugs (If there was any...). Cool enough to not make your jerky taste like my Mom's liver did. (God Bless her!)
My Presto Dehydro runs at 174 degrees. It can hit that fine.
But the manufacturer wants the Jerky "Finished" in a 210 degree oven for 10 minutes. Just to be safe...
Not much can get by the acid in your stomach.
Ponder this: 160 is the safe temperature for beef. 165 however is the safe temperature for fowl.
Oh my goodness! :eek:
I protect myself by consuming copious amounts of alcohol. I think it's working, so far I'm still alive. ;)
