How long will sliced Turkey remain good for wo refrigeration

I am refereing to the kind you buy in the supermarket in the ziplock
bags.  I assume it has preservatives it it.

thanx in advnce

"w/o refrigeration" is a little vague.

Is this in a cooler, a cabinet in an air-conditioned room, or on the
dashboard of your car in Arizona in Juy?

According to my mother-in-law, who is a culinary arts teacher, turkey
will enter a "danger zone" after 2 hours of no refrigeration.  At that
point, the bacteria will multiply to a point where it may make you
sick if you eat it.

i mean room temperature.
