String Cheese: How Long Does It Last?

Packaged string cheese is a popular snack food, especially for children, and can last for a long time when stored properly. But how long does it last exactly? And how can you tell if it's gone bad? This article will answer all your questions about the shelf life, storage, and spoilage of packaged string cheese.

Unopened packaged string cheese can last for 6-8 months

However, it's important to note that the exact duration may vary depending on storage conditions. To maximise the shelf life of string cheese, it should be stored in the refrigerator at all times and the package should not be opened until ready to use. Properly stored, unopened string cheese will typically last for about a week after the "Sell By" or "Best By" date on the package.

If you want to extend the shelf life even further, you can freeze the string cheese. To do this, tightly seal the original packaging and place it in the freezer. If freezing for longer than two months, it's recommended to place the package inside a heavy-duty freezer bag to prevent freezer burn. When properly frozen, string cheese will maintain its best quality for about eight months but will remain safe to consume beyond that period.

Additionally, it's worth noting that individually wrapped string cheese sticks have a longer shelf life than pre-sliced string cheese. This is because the individual packaging provides better protection from contamination, air exposure, and light. However, regardless of the packaging, it's always important to check for signs of spoilage before consuming string cheese, as even properly stored cheese can eventually go bad.

Opened packaged string cheese should be eaten within 7-10 days

Even if it's been opened for less than 7-10 days, it's important to check for signs of spoilage before consuming. If the cheese has developed a sour or "off" smell, or has dried out or hardened, it should be discarded. Other signs of spoilage include sliminess, discolouration, and the appearance of mould. If you spot any of these, the cheese should be thrown away.

If you're planning to eat the string cheese after the recommended 7-10 days, it's important to use your judgement. While it may still be safe to consume, there is an increased risk of bacteria growth and foodborne illness. If the cheese has been stored continuously at a proper refrigerator temperature, it may still be safe to eat, but its texture, flavour, and quality will have deteriorated.

To maximise the shelf life of string cheese, it's best not to open the package until you're ready to use it. An unopened package of string cheese will usually last for about 1 week after the "Sell By" or "Best By" date on the package, and often up to 1-2 weeks. To further extend its shelf life, it can be frozen.

Signs of spoilage include odd smells, mould, soft spots, sliminess, discolouration, and funky odours

Packaged string cheese is a convenient snack with a long shelf life. However, it's important to be vigilant about signs of spoilage to ensure food safety and maintain the best quality. Here are the key indicators to look out for:

Odd Smells or Pungent Aromas

The first sign of spoilage in string cheese is often an unusual or pungent smell. If the cheese no longer smells creamy and fresh, it's best to discard it. This odd aroma could be a sign of bacterial growth or other spoilage processes.

Mould

Mould is a common issue with dairy products, and string cheese is no exception. If you spot any bluish-grey, green, white, or fuzzy spots on the surface of the cheese, it's time to throw it out. Mould can indicate the presence of harmful bacteria and mycotoxins, which can cause foodborne illnesses.

Soft Spots or Sliminess

When checking your string cheese, be on the lookout for soft spots or a slimy texture. This could indicate bacterial growth or other spoilage processes. The cheese should feel firm when gently squeezed through the packaging. If it feels overly soft, shiny, or gummy, it's best to discard it.

Discolouration

Discolouration is another sign that your string cheese has gone bad. If you notice any off-colours like grey, yellow, or brown on the surface of the cheese, it's time to let it go. These discoloured spots could be a result of oxidation or bacterial growth.

Funky Odours

If your string cheese has developed an unpleasant or sour odour, it's definitely past its prime. This could be an indication of bacterial activity or other spoilage processes. Trust your senses and discard the cheese if it smells funky.

Trust Your Senses and Exercise Caution

When in doubt, always trust your senses and err on the side of caution. If the string cheese looks, smells, or tastes odd in any way, it's best to discard it. Consuming spoiled cheese can lead to foodborne illnesses, so it's important to be vigilant about spoilage indicators.

Freezing string cheese can extend its shelf life

String cheese is a popular snack, but sometimes you buy more than you can eat before it goes bad. The good news is that you can freeze string cheese to prevent it from spoiling. Freezing can more than double the shelf life of sealed string cheese.

String cheese generally has a long shelf life of at least 6 to 8 weeks and usually stays good for an extra 2 to 3 weeks. Once the package is opened, it is recommended to finish the cheese within 7 days for the best quality. However, freezing string cheese can extend its shelf life.

If you purchase individually wrapped string cheese, you can freeze them in their original packaging or place them in a freezer bag to keep them together in the freezer. Then, simply remove one piece of cheese at a time as needed. It is recommended to use a marker to write the date you froze the cheese on the packaging.

If you buy blocks of string cheese, you can still freeze them, but the process is a bit more time-consuming. You will need to wrap the cheese carefully. Consider slicing the cheese into smaller serving sizes so that you only need to thaw a small portion at a time. Wrap the desired serving size of string cheese in a double layer of plastic wrap, ensuring that no part of the cheese is exposed to the air. Any exposed cheese will dry out, become hard, and get freezer burn in the freezer. Place the double-wrapped string cheese in a freezer bag, seal the bag, and label it with the date.

Frozen string cheese is best used within 2 to 3 months of being frozen. To thaw frozen string cheese, remove the desired amount of cheese from the freezer and place it in the refrigerator for several hours or overnight. Leave the cheese wrapped until it is completely thawed to retain as much moisture as possible. Never thaw string cheese at room temperature. Use thawed string cheese within 2 days of being thawed and do not refreeze previously frozen string cheese.

String cheese should always be stored in the fridge

String cheese is a popular snack, perfect for lunch boxes, and enjoyed by both adults and children. It is a form of mozzarella that has been stretched and dried to achieve its characteristic stringy texture.

If you are going to be storing string cheese for a long time, it is worth noting that cheese can pick up other food odours from the fridge, so it is best to keep it in a container. Also, once the cheese is exposed to the air, it will start to dry out and lose its texture and flavour over time, so it is important to seal the packet tightly or transfer the cheese to a freezer bag, squeezing out as much air as possible.

Leaving string cheese unrefrigerated for more than two hours can lead to bacteria growth and an increased risk of food poisoning, so it is important to keep it cool.
