How Long Does Corn Last?

How long does corn last? The shelf life of corn, like most other fresh vegetables may not have a sell by date, use by date, or best before date so you have to go with purchase date in most cases. Although fresh corn on the cob is best and often only available during the summer months, it is enjoyed all year long in either canned or frozen form.

So, how long does corn last? When properly stored, the shelf life of corn is approximately…

Fresh Corn  lasts for 5-7 Days
Cooked Corn lasts for 5-7 Days

Of course, all foods last for a shorter period of time if they are not stored properly.

How to tell if corn is bad, rotten or spoiled?

It is the tips of the corn cob that will begin to go bad first. The best way to tell if your corn on the cob is going bad is to look at the top spray, if it is moist and darkening that is not a good sign. Often mold will begin to form at a moist tip, at which you will want to either cut off the top end plus an extra inch of the cob (if it has not spread too far) or just discard the entire ear of corn if it has spread beyond the tip. If fresh corn cobs have been left on the counter they will dry out, starting with the outer husk and the color will be a lighter green and dry looking. This corn will cook up chewy and flavorless instead of moist and tasty.

Cut fresh corn will begin to leak a milky substance as it ages and the corn will not be good once it sits in this liquid. Discard if there is odor or change in appearance.

Practicing proper hygiene and food safety discipline will help prevent food borne illness. There are, of course, certain health risks associated with spoiled corn, so always remember to practice food safety and enjoy your foods prior to their eat by dates.
