How Long is Sour Cream Good For After the Expiration Date?

Sour cream is a beloved dairy product, but like any other milk-based food it can go bad if not handled properly.

Sour cream can spoil quickly if exposed to bacteria and fungi, especially when stored at room temperature or exposed to moisture and air. This is especially true if left unprotected for extended periods of time.


Sour cream is a dairy product that adds richness to dishes from soups to baked goods. It’s popular among foodies and often available at an affordable price point.

It is essential to remember that sour cream has an expiration date on the tub, along with “best if used by” and “sell by.” These dates indicate when to purchase for optimal flavor and freshness; thus, purchasing before these dates has passed is recommended.

If you’re wondering how long sour cream remains fresh after its expiration date, know that it can stay fresh up to two weeks when stored properly and unopened in your refrigerator. However, keep in mind the temperature of your fridge and how well you store it to maximize freshness.

Storing sour cream correctly requires keeping it refrigerated and away from light. Doing this helps prevent spoilage of the product.

You can freeze sour cream to extend its shelf life. Just be mindful not to freeze too much at once as that could cause breakdown, watery consistency and flavor loss if frozen for too long.

When storing sour cream, it should either remain in its original container or be transferred to an airtight container. Doing this helps prevent bacterial growth and spoilage which could make the sour cream unfit for consumption.

Another way to ensure your sour cream stays fresh is to store it in an area of the fridge that’s not too hot or cold. Storing it on the door of the fridge is not recommended since temperature changes frequently and could cause spoilage more quickly.

It is also wise to move sour cream around the back of the fridge rather than placing it on front shelves. As temperatures in the back tend to be lower than those at the front, this can help keep your sour cream fresh for longer.

If you plan to store sour cream in an area that gets too warm, be sure to cover the top with foil. This will help seal the lid and keep air tight, which is essential for maintaining freshness of the sour cream.

To prevent spoilage, be sure to inspect your sour cream every couple of days for signs of spoilage. This includes checking for mold or an intensely sour odor.

Additionally, you should inspect the texture of your sour cream to guarantee it remains thick and creamy. If it becomes thin or watery, then it has likely passed its prime and should be discarded.


Sour cream is an indispensable dairy ingredient used in many dishes. Due to its high moisture content, it should be stored in the refrigerator to maintain freshness longer. It makes a delicious addition to salads, dips and casseroles alike!

It’s essential to know how long sour cream remains fresh after its expiration date, so you don’t have to throw away an otherwise perfect container before using it up. There are several factors which could potentially reduce its shelf life after expiration:

  1. When storing sour cream, keep it in a refrigerator at or below 40 degrees Fahrenheit to help keep it fresh longer and prevent bacteria from growing inside of it.
  2. Store sour cream in its original packaging with the lid on or in an airtight container to prevent air from getting into it and spoiling it.
  3. Avoid scooping out sour cream using utensils that have been exposed to other foods or liquids; this could speed up its spoilage.
  4. If sour cream begins to smell foul, it’s time to discard it. This could indicate that bacteria has grown on the product and it is no longer safe for consumption.
  5. If sour cream has started to turn yellow or discolor, it’s time for you to discard it. Eating this food item no longer poses a risk and could result in stomachaches or diarrhea.
  6. If sour cream has started to develop mold on it, this could be an indication that it’s starting to spoil. Mold produces mycotoxins which may pose risks for your health.
  7. If sour cream has become lumpy or runny, it’s time to discard it. This indicates that it no longer remains thick and creamy in consistency.
  8. If sour cream has begun to smell foul, it’s time to discard the container. Doing this can keep your family healthier by preventing them from consuming harmful toxins found in sour cream.
  9. If sour cream has become moldy, it should not be used in baking due to potential mycotoxins that could cause illness or even death in some individuals.
  10. Expired sour cream can be hazardous for both your health and ease of use. Not only does it have an unpleasant odor, it may turn yellow or discolor, making it difficult to work with.

However, if you use expired sour cream as directed and it shows no signs of spoilage, it’s safe to bake with. This includes making flaky pie crusts, homemade cream soup, deviled eggs, fluffy pancakes and salad dressing.


Expired sour cream should never be eaten as it contains bacteria that can make you ill. Not only is it not a nutritious snack, but consuming large quantities could even result in serious illness if consumed improperly.

Sour cream should always be stored in the refrigerator after purchase, and leftovers can last up to one week if left unopened. Once opened, however, sour cream has an extended shelf life of two weeks after its expiration date.

Storing sour cream is best done in the refrigerator, though it can also be stored in an airtight container or its original packaging. No matter where it’s kept, keep the temperature between 40 degrees Fahrenheit and 80 degrees Celsius to extend its shelf life.

Be sure to check the label for an expiration date. Sour cream typically spoils between 7-10 days past its printed expiration date due to prolonged exposure at room temperature. If you detect signs of spoilage, like an off smell or moldy growth, discard your sour cream immediately.

If you can’t locate a date, use the “best if used by” or “sell by” as an approximate guideline for how long your sour cream may remain fresh. For instance, milk, properly stored in the refrigerator, should remain stable up to five to seven days past its sell-by date before going sour.

As with any food item, sour cream can spoil if not stored correctly and safely. Be wary of any signs that your sour cream has gone bad and discard it before its expiration date.

Sour cream is a dairy product fermented to produce tart flavors. This involves mixing lactic acid bacteria with dairy cream in order to give it its characteristic tart taste.

To prevent sour cream from spoiling, it should always be stored in the refrigerator and never left at room temperature. If left out at room temperature for more than two hours, it will begin to decay and smell rancid.

Another essential tip when storing sour cream is to use clean spoons for scooping it out. Otherwise, the cream could potentially harbor bacteria and fungi.

Kechup, mustard and mayonnaise should also be handled with care; double-dipping can spread bacteria throughout the container.

When determining how long food items can safely be eaten after their expiration dates, you should take into account the storage guidelines of that item. While you may be able to eat something past its expiration date, it’s best to discard anything that has gone off, so as not to risk becoming ill.
