Can it sit out?
Processed cheese slices is perishable — the FSIS 2-hour rule applies.
Perishable food left at room temperature for more than 2 hours should be thrown out — 1 hour if it’s 90°F or hotter (a picnic, a hot car, a summer kitchen).
How to tell if processed cheese slices has gone bad
- Slices gone hard and curling at the corners
- Grease beading on the plastic between slices
- Mold of any kind — a slice this soft gets thrown, not trimmed
- A sour smell where there should be almost none
When in doubt, throw it out.
Keep the stack in its sleeve inside a sealed bag — slices left open dry into plastic-hard shingles overnight.
