How to Tell if Yogurt is Bad?

It can be challenging to tell if Yogurt is spoilt, but there are a few simple ways to tell. Look for the words “natural” or “unpasteurized” on the labels of your Yogurt. If the Yogurt you bought says “pasteurized,” it’s probably not natural and should be thrown out. Similarly, if the product’s box reads “pasteurized,” you shouldn’t eat it.

How to Tell if Yogurt is Bad?

  • Fellow yogurt fans, but here it is again: Yogurt does go wrong, and if you eat poor Yogurt, you’re in trouble (more on that later). You might be perplexed about how something full of bacteria and yeast can deteriorate.
  • The trouble is, just because Yogurt is high in healthy bacteria doesn’t mean it’s immune to the growth of nasty germs. Certain conditions (hot temperatures) favor the growth of harmful bacteria in cheese, as they do in any dairy product.
  • Also, opened Yogurt spoils faster than unopened Yogurt, and germs “may develop more rapidly in yogurts with added sugar and fruit,” according to So, what happens if you leave your Yogurt in the fridge for too long?
  • Yogurt should be refrigerated as soon as possible to maintain its freshness and shelf life at a temperature of 40 degrees Fahrenheit or less. (Hint: If your refrigerator is warmer than that, something is wrong.)

If your Yogurt has gone moldy, it’s time to toss it. While mold doesn’t always indicate it’s dangerous, it’s best to stay away from it. It’s tempting to eat terrible Yogurt, but it’s not a good idea. The microorganisms in it could make you sick. If your Yogurt has mold on it, it’s time to throw it out. If it has mold on it, toss it out right away.

How Long does Yogurt Last in the Fridge?

  • Yogurt can be kept in the refrigerator for one to two weeks at 40 degrees Fahrenheit or frozen for one to two months at 0 degrees Fahrenheit. Cottage cheese, ricotta, and Brie can be kept in the refrigerator for up to a week, but they don’t freeze well.
  • A larger-than-normal amount of liquid on the surface (don’t worry, Greek Yogurt is especially prone to this), a curdling texture near the bottom, and any trace of mold are all red flags. According to the experts at StillTasty, this means the entire product has probably gone rotten.
  • While ordinary Yogurt won’t stay a year in your fridge, according to the USDA’s FreshKeeper app, Yogurt is generally good to eat for up to two weeks after purchase. The most straightforward approach to avoid eating Yogurt that has gone bad is to keep track of how long it has been in your fridge.

Health Benefits of Yogurt

Here are some health benefits of Yogurt

It has the Potential to Boost your Immune System

  • Regularly eating Yogurt, mainly if it contains probiotics, can help to improve your immune system and minimize your chances of getting sick.
  • Probiotics have been demonstrated to lower inflammation associated with various health issues, including viral infections and gut problems.
  • According to research, probiotics have been shown to help lessen the occurrence, length, and severity of the common cold in some cases.
  • Furthermore, the immune-boosting qualities of Yogurt are attributed in part to the trace minerals magnesium, selenium, and zinc, which are renowned for their role in immune system function.
  • Yogurts enhanced with vitamin D may help your immune system even more. Vitamin D has been researched to see if it can help prevent infections like the common cold and flu.

It has the Potential to Improve Heart Health

  • One of the causes for the debate regarding Yogurt’s healthiness is its fat level. It’s primarily saturated fat, with a minor quantity of monounsaturated fatty acids thrown in for good measure.
  • Saturated fat was once linked to heart disease, but new research suggests that this is no longer the case. Nonetheless, fat-free and low-fat Yogurt is still prevalent in the United States.
  • There is no conclusive evidence that the fat in Yogurt is unhealthy, and it may be beneficial to one’s heart health.
  • According to several studies, consuming saturated fat from whole-milk products raises “good” HDL cholesterol, which may help to safeguard heart health. Yogurt consumption has been shown in several trials to lessen the overall incidence of heart disease.
  • Furthermore, dairy products such as Yogurt have been demonstrated to aid in the reduction of high blood pressure, a key risk factor for heart disease. The effects appear to be strongest among people already diagnosed with high blood pressure.

It’s a Good Source of Protein

  • Yogurt has a high protein content, with roughly 12 grams every 7 ounces (200 grams)
  • Protein has been demonstrated to aid metabolism by raising your daily energy expenditure or the number of calories you burn.
  • Saturated fat was once linked to heart disease, but new research suggests that this is no longer the case. Nonetheless, fat-free and low-fat Yogurt is still prevalent in the United States.
  • Protein has been demonstrated to aid metabolism by raising your daily energy expenditure or the number of calories you burn.
  • Protein is also crucial for appetite control since it boosts the production of hormones that signal fullness. It may naturally reduce your overall calorie intake, which is excellent for weight management.
  • Greek Yogurt has been demonstrated to have a more significant impact on appetite management and hunger delay than standard Yogurt with less protein.

The liquid developed on top of the Yogurt is another indicator of poor Yogurt. This liquid may appear to be mold or water, but it is nutrient-dense. If it’s overly liquid, it’s best to throw it out. This is because a liquid yogurt will change the texture and flavor of the Yogurt. It’s not good if you have rotten Yogurt, and it’s a sign that it’s reached the end of its useful life.

If you’re unsure if your Yogurt is over its expiration date, you can always taste it if it has a sour or bitter flavor. You can also smell it to see if it’s true. The water on top of the Yogurt indicates that it has gone sour. It is a good source of nutrients. If you find mold on it, it’s probably past its prime.


Take your Yogurt to a store if you’re unsure what hue it is. Bacteria infect sour Yogurt most of the time, indicating that Yogurt is unhealthy. If it’s still a little too old, it’s best to toss it out. If you’re not careful, it’ll be far more likely to get mold-infested. A sour odor can also indicate rotten Yogurt.

Fortunately, there are a few methods for determining whether Yogurt is terrible or not. Inhalation is the first approach. You can still use the product even if you smell something off, such as sourness or mold. Any item that has liquid in it or a foul odor should be thrown away. The best course of action is to discard it if it is excessively liquid. If it feels too sticky, it probably has passed its prime.
