Fridge at 4 °C (40 °F) or colder, freezer at −18 °C (0 °F). Freezer times are for best quality: food kept frozen stays safe, but slowly loses taste and texture. These times are USDA guidance, not a guarantee. When in doubt, throw it out.

How to tell if corn has gone bad

Slimy, dark or moldy husks or silk.
Shriveled, dented or discolored kernels, or kernels that are mushy rather than plump.
A sour or musty smell.

How to store corn on the cob

Corn's sugar turns to starch soon after picking, so it tastes sweetest the day you buy it.
Keep the husks on and refrigerate the ears as soon as you get home, in a loose bag.
Husk it only just before cooking.
Refrigerate cooked corn within 2 hours and eat it within 3 to 4 days, like other cooked vegetables.

Can you freeze corn?

Yes, for about 8 months. Husk the ears, blanch them for 4 to 6 minutes depending on size, cool them in ice water and freeze them whole, or cut the kernels off and freeze them in bags. Cook from frozen.
