How Do You Know When Sour Cream Goes Bad?
Sour cream usually goes bad when it develops an off smell, abnormal texture, or mold growth on the surface or in the container. It can also turn yellow, brown, or greenish in color and become too watery or curdled. Sour cream that has been left out at room temperature for too long or past its expiration date can also spoil and should not be consumed. It’s always best to check the expiration date and use-by date of the product before consuming it.
