Shredded Cheese: How Long Does It Last?

How long does shredded cheese last once opened? The answer depends on the type of cheese and how it's stored. Soft cheeses like cheddar and mozzarella will only be good for one to two weeks after opening, while hard cheeses like parmesan and Swiss should be eaten within a month. If stored properly, shredded cheese can be consumed beyond its Best By date, but it's important to use your judgment and look out for signs of spoilage like mold, discoloration, or off odors. To extend the shelf life, shredded cheese can be frozen and consumed within six months.

Soft cheese lasts 1-2 weeks in the fridge

For example, soft cheeses like cheddar and mozzarella will only be good for about one to two weeks after opening, according to food scientist Janilyn Hutchings. On the other hand, hard cheeses like parmesan and Swiss can be consumed within a month of purchase.

To maximise the shelf life of soft cheese, it is important to store it properly. This involves keeping it refrigerated at all times and sealing it tightly in its original packaging or placing it in resealable plastic bags or airtight containers.

It is also important to note that soft cheese can spoil before the "best-by" date if there are quality control issues during manufacturing or improper storage at the store or in your home. Therefore, it is always a good idea to inspect your cheese for any signs of spoilage, such as an off odor, discolouration, or spots of mold, before consuming it. If you notice any of these signs, it is best to discard the cheese.

Hard cheese lasts 3-4 weeks in the fridge

Hard cheese, such as aged cheddar, aged gouda, and parmesan, can last about 3-4 weeks in the fridge. This is because hard cheeses are low in moisture, making it difficult for bacteria to flourish.

To ensure your hard cheese lasts the full 3-4 weeks, it's important to follow proper storage procedures. Firstly, remove the cheese from its plastic packaging. Then, wrap it loosely in a breathable material, such as wax paper or cheese paper. Finally, place the cheese in an airtight container and store it in the refrigerator.

It's worth noting that the shelf life of hard cheese may vary depending on the brand and the storage conditions. Additionally, while hard cheese can be stored outside of the fridge, it will last much longer if refrigerated.

When it comes to determining if your hard cheese has gone bad, there are a few signs to look out for. If you notice any visible mold, an unpleasant smell, or changes in texture or colour, it's best to discard the cheese. However, if you notice white specks or crystallized patches on aged hard cheeses, these are likely calcium lactate crystals and are safe to consume.

Shredded cheese can be frozen to extend its shelf life

Shredded cheese is a convenient way to add flavour to a variety of dishes, from chilli to nachos. However, it doesn't last long in the fridge, so it's a good idea to consider freezing it to extend its shelf life.

Shredded cheese will last in the refrigerator for 3 to 5 days after opening, but freezing it can extend its life by several months. This is especially useful if you don't plan on using the cheese within a few days of opening.

To freeze shredded cheese, portion it into smaller bags or containers, ensuring they are sealed tightly. It is also important to use clean utensils and hands when handling the cheese to avoid contamination.

When you are ready to use the frozen cheese, simply thaw it and sprinkle it over your favourite dishes. Freezing shredded cheese is a great way to reduce food waste and ensure you always have cheese on hand for a quick meal.

It is worth noting that freezing shredded cheese may affect its texture and quality, so it is best used in cooked dishes rather than eaten raw. Additionally, always check for any signs of spoilage, such as mould or an unpleasant odour, before consuming any cheese, regardless of its shelf life or storage method.

Cheese should be stored in an airtight container

To ensure shredded cheese stays fresh for as long as possible, it should be stored in an airtight container. This is because shredded cheese has a larger surface area than a block of cheese, which means it is more prone to drying out and going bad. By using an airtight container, you can help to maintain the moisture content of the cheese, keeping it fresher for longer.

It is also important to keep the cheese refrigerated at all times. The ideal refrigerator temperature is below 40°F (4°C). At higher temperatures, bacteria can multiply rapidly, increasing the risk of food spoilage. If shredded cheese is left at room temperature for more than two hours, it should be discarded.

In addition to refrigeration, you can further extend the shelf life of shredded cheese by freezing it. Freezing can be especially useful if you don't plan on using the cheese within the recommended time frame. To freeze shredded cheese, tightly seal the original packaging and place it in the freezer. If freezing for longer than two months, it is advisable to place the package inside a heavy-duty freezer bag to prevent freezer burn. Frozen shredded cheese will maintain its best quality for about eight months but can be safely stored indefinitely at a constant temperature of 0°F (-18°C).

When it comes to the shelf life of shredded cheese, the type of cheese matters. Hard cheeses like parmesan and Swiss will last longer than soft cheeses like cheddar and mozzarella. Hard cheeses can be consumed up to a month after opening, while soft cheeses should be eaten within one to two weeks.

It is worth noting that the recommended storage times are based on maintaining optimal flavour and texture. The cheese may still be safe to consume beyond these time frames, as long as it shows no signs of spoilage. Always use your best judgement and inspect the cheese for any off odours, discolouration, or mould before consuming.

Signs of spoiled cheese include mould, discolouring, and a bad smell

It's important to be vigilant about the signs of spoiled cheese, as consuming it can lead to digestive issues such as nausea and diarrhoea. The first sign of spoiled cheese is usually mould. Mould can be fuzzy and green, white, black, blue, or grey. If you spot any of these colours on your shredded cheese, it's best to discard it.

Discolouration is another sign of spoiled cheese. For example, if a creamy white cheddar has turned yellowish or grey, it's time to throw it out.

Spoiled cheese may also emit a sour or ammonia-like odour. If your shredded cheese smells unusual, even if there is no visible mould, it's best to avoid eating it. Trust your senses and use your best judgement.

In addition to these signs, spoiled cheese may also exhibit a change in texture. For instance, a formerly firm block of cheese may become slimy, sticky, or wet to the touch. Hard cheeses like Parmesan or Pecorino may develop a tough, dry texture or start to crumble easily.

It's worth noting that some cheeses, like Brie or Camembert, naturally have a soft, runny texture. Therefore, it's important to consider the other signs of spoilage before making a decision.

To prevent cheese spoilage, it's crucial to practise proper storage techniques. Store cheese in the refrigerator at the appropriate temperature, wrapped tightly in wax paper, aluminium foil, or breathable packaging like specialised cheese paper. Change plastic wrap frequently to avoid trapping excess moisture, which creates the perfect environment for mould and bacteria.

Additionally, cross-contamination can occur when cheese is stored alongside strong-smelling foods or near spoiled items. It's best to dedicate a specific area in your refrigerator for storing cheese, away from pungent foods, to prevent unwanted odours and flavours from transferring.
