How long can you keep pimientos from spoiling?

4 days to a week depending on packaging materials. ziplock or butcher paper is best.

Potentially hazardous food should not be left unrefrigerated for more than 2 hours. Make that one if the ambient temperature is very warm. At that point, it should be refrigerated or re-heated.

Approximately 5-7 years. I believe that this answer is meant to be funny. Live clams after being kept in any refrigerator about one week will die and begin to stink.l You certainly would not want to...

If you haven't cut it yet, a green bell pepper will keep for about a week (depending on how fresh it was when you purchased it).

As long as you want.
