How To Tell If Sour Cream Is Bad

Rate this post

I like using sour cream in a variety of meals, but I don’t always use it all up. The container has been sitting in the fridge for a long, and I’m not sure whether I should use it. So, how can you know whether sour cream is dangerous for you, and what should you do if it is?

Sour cream has a longer shelf life than most milk products, but it will split, get lumpy, acquire an unpleasant odor, stink, and eventually mold. If your sour cream shows any of these indicators, it’s time to throw it away.

Sometimes things go wrong sooner than you think. But don’t worry, I’ll show you six warning signals to avoid using poor sour cream and becoming ill.

How To Know If Sour Cream Is Bad

It’s Expired

Before using sour cream, always check the expiration date. Sour cream may become bad beyond its expiry date, even if it has never been opened. If the expiration date has passed, discard it and replace it.

Don’t just depend on the written dates and believe your stuff will be OK till then. Many variables influence the shelf life of sour cream, the most important of which is storage temperature in the grocery store and at home.

whether you can’t find the date, one of the other symptoms will let you know whether your sour cream has gone bad.

It Smells Awful

When dairy products like milk and yogurt go sour, they frequently emit a pungent foul odor. Sour cream is the same way. If it smells really sour, vinegary, or off, it’s time to throw it away.

If in doubt, take a smell before using it in a recipe. If the odor is off, don’t consume or cook with it. Simply toss it away.

It Tastes Off

I don’t encourage knowingly tasting off things, but if you do and it has a harsh, sour, or bitter flavor, throw it away.

Consuming contaminated sour cream may result in food poisoning, necessitating a trip to the emergency department.

It’s Lumpy

Curdling or lumpy sour cream is another indicator that dairy has gone bad. This is common when it is stored at an excessively high temperature, on the counter, or left out overnight. If you go food shopping on a hot summer day, try bringing everything home in a cooler.

Do not make the same mistake I did. If it seems lumpy, double-check the sour cream and not the cottage cheese.

Unfortunately, the lumpiness is still more evidence that it cannot be preserved and must be removed.

It’s Watery And Separated

When you open your sour cream container, you could see some liquid collecting in the low regions on the surface. Some liquid separation is OK; you may combine the sour cream and it will still be edible.

However, if there is a lot of liquid in your container of sour cream that seems to be separated, you should not ingest it. It’s also possible that the leftover solids are lumpy. When two indicators appear, you know your sour cream is rotten.

There’s Mold

If there is any discoloration or mold, do not use it. I’ve noticed dark blue and fuzzy mold on sour cream, but several others have also reported seeing pink mold.

Don’t think you can just scrape the mold off the top and utilize the remainder. Mold has a complicated network of roots that may reach far into the surface of your sour cream. They are so little that you won’t be able to see them unless you use a microscope.

While still delicious, sour cream should be white. Bacterial growth may also appear and cause the hue to shift to yellow, blue, or pink. Throw it away if the color changes.
