Can You Get Sick From Expired Sour Cream?
Off the top, it is important to know that you can, indeed, get sick from expired sour cream.
But how long it has been expired and what conditions it was kept in makes a difference.
Because sour cream is a dairy product, you can get sick from it rather easily if it isn’t stored properly or goes bad. Consuming expired sour cream can cause you to get food poisoning and may yield a variety of symptoms including nausea, stomach cramping, diarrhea, and much more.
How Long Past Expiration Date Can You Use Sour Cream?
Assuming that you kept your sour cream refrigerated at least 40 degrees Fahrenheit, you can expect your sour cream to last anywhere from 1-3 weeks past expiry.
With that said, if you notice any signs of deterioration such as mold, an off smell, or an off taste, you should pitch your sour cream and buy a fresh container.
Above all, remember never to consume anything that makes you sick.
How Long Is Expired Sour Cream Good Unopened?
Expired sour cream can safely last anywhere from 1-3 weeks unopened, but that’s assuming that you’ve kept the sour cream in the fridge at 40 degrees Fahrenheit the entire time.
If you leave sour cream out for any more than 2 hours, you risk it going rancid and will need to purchase a new one.
Expired Sour Cream Never Opened
Whether opened or not, rules for sour cream remain the same.
Though you’ll want opened sour cream to remain in an airtight container in the fridge, even unopened sour cream risks spoilage if you let it remain in your fridge for too long.
As a rule of thumb, don’t eat any sour cream that has gone beyond three weeks of its expiry date.
And be careful…
Because sour cream is a dairy product you may find that it goes rancid faster, and also, yields more severe complications when digested the longer it sits expired.
Sour Cream 3 Months Past Expiration
Sour cream that goes three months past expiration should not be consumed.
According to the USDA, it is best to consume sour cream for only 1-3 weeks after expiration. Thus, keeping sour cream that has been in the fridge for 12 weeks, the equivalent of three months, is too long.
By eating dairy products that have gone bad, such as spoiled sour cream or even spoiled milk, you run the risk of becoming very ill. It is far better to discard dairy products after expiry.

How Do You Know When Sour Cream Goes Bad?
How to Know If Sour Cream Is Bad?
As with most things, sour cream will develop an unfamiliar look, taste, and smell after spoiling.
If you notice that your sour cream has become yellow or discolored in any way, discontinue use.
If you notice mold on sour cream, it is yet another sign of spoilage.
Sour cream that doesn’t taste or smell quite right is also likely unsafe to eat.
And most importantly, if your sour cream has gone 1-3 weeks past expiry, it is best you toss it and purchase fresh sour cream.
If you find that your sour cream has gone bad, you can replace the sour cream with buttermilk in the case of dressings or baked goodies. Although the two seem very different, they are very similar when you compare buttermilk vs sour cream.

Why Does Sour Cream Get Watery?
Is Sour Cream Still Good If It’s Watery?
That depends.
Sour cream that has water or liquid on top isn’t odd. In fact, it can be perfectly normal. That’s because the water that presents itself on both sour cream and yogurt is known as whey. It’s naturally occurring and is perfectly safe.
If, however, there are other signs of spoilage such as a bad smell, bad taste, mold, or discoloration, your best bet is to opt for new sour cream.

What Does Bad Sour Cream Smell Like?
Sour cream naturally has a tangy odor. However, if that smell is stronger than usual or seems particularly rotten, chances are that the sour cream has gone bad.
Can You Use Spoiled Sour Cream For Baking?
Spoiled Sour Cream
It’s best to avoid eating spoiled sour cream if it has been 1-3 weeks past expiry.
Despite being in baked goods, the spoiled sour cream can still induce food poisoning and unwanted symptoms when consumed. Thus, it is best to avoid using sour cream 1-3 weeks after the printed expiration date, even when using it to bake.
Is your sour cream getting close to its expiration date?
