Pecans can and should be frozen if you are not going to be eating them right away. It will be extremely important to make sure that you properly store your nuts when you get them home from the supermarket, just so you will be able to keep them from going completely rancid.

By keeping your pecans in the freezer you will be able to prevent the nuts from going bad and as a result suffering from food poisoning if you eat them. If you do plan on keeping your pecans in the freezer, it will be important to make sure that you keep them in an airtight container so that they do not spoil.
