Store-bought chicken broth is a staple ingredient in my kitchen, but the other day when I went to make soup, I did a double take. I couldn't remember the last time I used chicken broth and the container was open. Although the expiration date said November 2009, I wasn't sure if the stock was still good. After doing some research, I learned that once a box of chicken broth is open, it should be kept in the refrigerator for no longer than a week. The date on the outside is for an unopened box. Homemade stock [1] will last in the fridge for four days.

Freezing both homemade and store-bought chicken stock will extend its life for about 60 days.
