Sour cream is a dairy product that can quickly go sour, harboring harmful bacteria that could make you sick.
Once sour cream goes bad, it may turn moldy or develop colored spots visible on its surface. Clumpiness and chunkiness will soon follow – any time any of these symptoms present themselves, toss out the product immediately!
The Smell
If your sour cream has an unusually strong and unpleasant aroma that surpasses its traditional tangy aroma, it could be bad. Bacteria growth in sour cream can intensify this scent to the point of becoming offensive; additionally, the presence of harmful microorganisms could result in food poisoning with stomach cramps and nausea being common symptoms.
As well as checking its aroma, it is also wise to evaluate its color. Fresh sour cream should be white in hue, while any changes such as yellowing or even green tinting indicate too long of storage time and make it unsafe to consume.
Unsafe storage practices will cause sour cream to spoil within several days after opening it, and it is easy to detect this fact. Mold growth on its surface indicates it may no longer be safe to consume and could spread further throughout the product. It should therefore be discarded immediately.
Before tasting and smelling your sour cream, be sure to inspect its texture and temperature as well. Sour cream should have a thick and creamy consistency when fresh; once it has been compromised by bacteria or mold growth it can quickly turn watery and become unpleasant for consumption. Also important: always store sour cream in the fridge; storing it outside could lead to bacteria growth which turns it moldy while the bacteria causes rancid taste!
If your sour cream contains a thin layer of milky liquid on its surface, don’t panic. This substance is called whey and it is quite normal for gelled dairy products such as sour cream to develop it when left in the fridge for too long.
The Color
Sour cream doesn’t last very long in the fridge, even when opened only occasionally. Unfortunately, though, it can go bad quickly; but the good news is that most times you can tell by simply looking or smelling.
If your sour cream smells rancid or sour, dispose of it. Eating this past its prime could make you sick; bacteria growing within it could make stomachache, nausea, diarrhea or fever more likely.
As with other foods, sour cream can tell us if it has gone bad by its color alone. If it turns pink or green in hue, that indicates its spoilage and should not be consumed. In addition, chunks of sour cream floating at the top of your container indicate separation, suggesting they no longer form part of its mass.
Fresh sour cream should have an ideal creamy texture; however, as it sits in the fridge it can often separate and form a layer of liquid on top known as whey that needs to be consumed safely before refrigerating again. Although not ideal, whey still can be safely eaten alongside its parent product: sour cream!
As it sits in the refrigerator, sour cream will begin to lose its creamy texture and could begin looking watery or lumpy. Furthermore, its color could change from its initial hue of yellow or white into something pinker or greyer.
As it may contain harmful bacteria which could potentially lead to food poisoning, using this sour cream should be done so with extreme caution.
Taste testing sour cream can help determine its quality. If it tastes delicious, continue using it. However, if it has an off flavor or strange hue that makes it unsuitable to be consumed – especially if mold has grown on it – discard immediately as this could be unsafe to eat.
The Texture
When it comes to sour cream, texture is everything. Fresh product should be silky-smooth with no signs of spoilage such as an unpleasant sour smell or watery appearance; any indications that something has gone amiss should prompt a swift action plan for disposal.
Sour cream is a dairy product produced through fermenting milk with lactic acid bacteria and is an immensely versatile addition to many dishes, from soups to salad dressings. The lactic acid provides its distinct sour flavor while thickening up the cream itself. When properly stored and kept cool it can remain fresh for months; however if left out too long it could go rancid and potentially cause food poisoning.
To prevent this from occurring, it’s crucial to properly store sour cream. This means keeping it refrigerated at all times and not leaving it sitting on the counter too long before refrigerating it again. Furthermore, try and use up all your opened containers within two hours or consuming it immediately!
If you have an abundance of sour cream in a large container, it may be beneficial to consume it quickly by scooping out what you need and returning the remaining cream back into the fridge – this will prevent spoilage as well as enable more homemade versions in future.
Mold growth is one of the telltale signs that your sour cream has gone bad, so if any black, green, or blue spots appear on its surface it should be thrown out immediately.
Curdling can also be an indication that your sour cream has gone bad, which could occur due to either keeping it at an excessively high temperature, being exposed to heat during storage and transportation, or simply being left open too long before opening it. Therefore, it is wise to always double check its temperature before opening any container of sour cream.

The Temperature
As opposed to most dairy products, which typically last about a week after they’ve been opened, sour cream tends to spoil rapidly once opened. Although not as long-lived as butter or heavy cream, however, sour cream still outlasts most fresh dairy. Partly this is because fermentation helps it maintain a more constant temperature than non-fermented versions do.
Storage conditions that promote bacteria growth may lead to spoilage in sour cream, so for optimal freshness it should be stored at an ideal temperature in your fridge and not on the countertop or near hot areas of the fridge where its freshness could rapidly deteriorate.
For optimal sour cream storage conditions, the safest place in your refrigerator would be at 40 F – this temperature allows it to maintain the best results during its shelf life and may help ensure you make it past its expiration date.
Once sour cream goes bad, it becomes rancid-smelling and has an off-putting sour flavor, not only making it taste bad but also potentially leading to stomach discomfort or food poisoning if consumed. To protect against this scenario, always store sour cream in the fridge until ready for use and keep track of when its expiration date approaches.
As well as looking out for mold or an unpleasant odor, you should also inspect the appearance of the sour cream. Spoilt sour cream typically features fuzzy grey or greenish features and may become thicker than usual; if any of these traits exist in yours it’s time to throw it out immediately.
Fermented products like sour cream can still spoil over time and go bad, however using the signs listed above, you can quickly identify whether yours has gone off before it poses any health hazards to yourself or family. By adhering to these tips, sour cream should remain fresher longer so you can experience its delicious taste and texture at its peak!
