Does corned beef go bad?
Yes. The fridge time above is the window USDA gives for good quality; after it, corned beef may still be safe for a short while but quality drops and spoilage signs start. The date on the package is the maker's quality promise; the times here count from purchase unless marked "from the package date".
Two numbers to keep in mind: a fridge at 40 F (4 C) or below, and no more than 2 hours at room temperature (1 hour above 90 F / 32 C) for anything perishable.
How to tell corned beef has gone bad
General signs for meat: smoked or processed, the group USDA lists corned beef under.
- Slimy or sticky film on hot dogs or sliced sausage
- Grey or green tinge developing on the surface
- Sour or off smell replacing the usual smoky scent
- Hardened, dried-out edges on bacon left uncovered too long
- Package losing its vacuum seal or ballooning with gas
