Why Can You Use a Yogurt Past its Use By Date for So Long?

Expiry dates or “use by” dates are usually a guide to the store owners not to us, consumers after we purchase them. Now that we know that the expiry date talks about the freshness of the products, we can use a yogurt even after two weeks of its expiry date. Yogurts are made by so-called “bacteria” It is essentially made from spoilt milk in the first place. Therefore, for yogurt to get spoilt further, it takes a lot of time. Another way to save your yogurt a little longer is by storing it in the fridge and not breaking open the seal. Opened seals spoil the yogurt, and it’s still fine to eat an expired yogurt but it’s never okay to eat a spoilt yogurt. If you eat a yogurt two weeks past its use-by date, you will get mild side effects such as stomach cramps and so on. But if you eat an opened tin, you might have severe vomiting which is a result of food poisoning.

Storage is also very important with the life of any food. Some studies suggest that a yogurt stays fresh only for 2 hours if it is kept outside a refrigerator. They say it starts developing a mold if it is not refrigerated.

At any time, it is best to check if the smell of the yogurt is normal. If it has a bad stench, it means, the yogurt is no longer good to eat and you have to toss the container.
