Do you have a jar of sour cream in the fridge for weeks and wonder if it is still safe to eat? Here is the answer.
The shelf life of sour cream
According to the USDA, sour cream (unopened or unopened) is the value for up to three weeks after the expiration date, provided it act kept in the refrigerator. Inspect your sour cream to make sure that it has not developed a bad odor or unpleasant odor, and if nothing seems annoying, consider using it safely.
This Golden Rule is the concept for food quality and safe operation by the Food Marketing Institute in its Consumer Guide “The Food Keeper.” They also give a window of seven to 21 days to use sour cream, assuming it is refrigerated at 40F.
What can make cream bad?
Sour cream is produced from milk, pasteurized to kill the most harmful bacteria. It acts then fermented by healthy bacteria making lactic acid, which gives it a sour taste.
Commercially dispensed sour cream should meet safety standards, while homemade sour cream can be a clown for other types of bacteria. Consider sour cream as a living product; It still contains living elements that have not been shut down by damming procedures.
Bacteria and molds enjoy life in your cream

Signs that your cream has gone bad
Even if your cream is not yet on the “first” or “before consumption” date, do not eat it if you notice:
An unpleasant smell: Take a sip of your cream. If it is cold, unhealthy, or stinky from the typical sour smell, you will have additional growth that will affect taste and safety.
Mold: If you notice the mounting on the surface, the entire container should disappear. Do not be tempted to remove the top pan and eat the rest. The mold can move through what you can see with the naked eye.
Yellow or discolored sour cream: If the cream is no longer white, it is influential that you have significant growth of bacteria and fungi.
The food companion life can act significantly shortened if it acts not handled correctly. Your sour cream may have, at some point, been left at room temperature by the manufacturer, India, or someone living in your home, or someone may have put a dirty finger or spine in the container. Depend on your eyesight and your nose when they tell you something is wrong.
A sign that is not a concern is different. It is normal to separate the liquid from the solid cream. You can dry it or remix it, provided you use a clean spine.
