Cheddar cheese is a firm and relatively hard cheese that is produced by finely grating or shredding cheddar. Cheddar shredded cheese is a versatile and popular dairy product. However, it is crucial to know when it has gone bad. Shredded cheddar cheese should be discarded if left out for more than 2 hours at room temperature. To extend its shelf life, it is recommended to store it in a tightly sealed package in the freezer. When it comes to determining if shredded cheddar cheese has gone bad, visual cues such as discoloration, hardening, or drying out can be indicators. Additionally, a noticeable change in smell or taste could be a sign of spoilage.

What You'll Learn
- Storage conditions: Refrigerate at all times, and use within a certain timeframe after opening
- Freezing shredded cheddar: Tightly seal the original packaging and place in the freezer

Storage conditions: Refrigerate at all times, and use within a certain timeframe after opening
Cheddar shredded cheese should be stored in the refrigerator at all times. The ideal refrigerator temperature is below 40°F (4°C). To maximise the shelf life of shredded cheddar cheese after opening, seal the original packaging tightly or transfer the cheese to resealable plastic bags or airtight containers.
Properly stored, an opened package of shredded cheddar cheese will last for about 5 to 7 days in the refrigerator. Consume or freeze the shredded cheddar cheese within this time, even if the "Best By," "Best if Used By," or "Use By" date has not passed. Cheddar shredded cheese should be discarded if left out at room temperature for more than 2 hours, as bacteria grow rapidly at temperatures between 40 °F and 140 °F.
To further extend the shelf life of opened shredded cheddar cheese, it can be frozen. To freeze shredded cheddar cheese, tightly seal the original packaging and place it in the freezer. If freezing for longer than 2 months, place the package inside a heavy-duty freezer bag to prevent freezer burn. Frozen cheddar cheese may lose some of its texture and flavour, so it is best suited for cooked dishes such as sauces, soups, and casseroles. Properly stored, shredded cheddar cheese will maintain its best quality for about 8 months in the freezer, but it will remain safe to consume beyond this timeframe.

Freezing shredded cheddar: Tightly seal the original packaging and place in the freezer
Freezing shredded cheddar is a great way to make it last longer, but it's important to note that its texture will change. Cheddar is a hard cheese, and hard cheeses tend to hold up better in the freezer than soft cheeses.
To freeze shredded cheddar, start with the original packaging. Tightly seal it to prevent freezer burn and reduce oxygen contact, which can be done with a vacuum sealer if you have one. If not, use plastic wrap and then again in foil. Place the sealed package in the freezer.
When you're ready to use your frozen cheddar, it's best to thaw it in the refrigerator. Place the cheese in its original packaging or an airtight container and allow it to thaw for a good 12 hours or so. It's best to eat the cheese after it's been thawed, and not to re-freeze it, as this will affect the texture even more.

Visual cues: Discoloration, mould, hardening or drying out
Shredded cheddar cheese is a versatile and popular dairy product. As a hard cheese, it can last up to 4 weeks in the fridge. However, it's important to know how to identify when shredded cheddar cheese has gone bad.
Visual cues: Discoloration, mould, hardening, or drying out
One of the most obvious signs that shredded cheddar cheese has gone bad is discoloration. Hard cheeses like cheddar usually have a distinct colour, and if you notice that your shredded cheddar is turning dark or has any discoloured shreds, it's best to discard it.
Mould is another visual cue that indicates that your shredded cheddar cheese has spoiled. If you see any blue or green mould on the surface, it's important to throw away the entire package, especially if it's a soft cheese. However, if it's a hard cheese like cheddar, you can carefully cut away the mouldy part with a clean knife, making sure not to contaminate the rest of the cheese.
Hardened or dried-out cheese is also a sign of spoilage. Cheddar cheese is known for its firm and flaky texture, but if it starts to harden or dry out, it has likely lost its freshness. This can happen if the cheese is not stored properly or if it has been exposed to air for too long.
To extend the shelf life of shredded cheddar cheese, it's recommended to keep it refrigerated at all times and tightly seal the original packaging if freezing. Additionally, performing a sniff test can help identify spoilage, as cheese that has gone bad may have an unpleasant smell.

Smell and taste: If it smells or tastes bad, throw it away
Smell and taste are two of our most powerful senses and can be used to determine whether food is safe to eat. This is especially true for cheddar shredded cheese. If your shredded cheddar cheese smells or tastes bad, throw it away.
While shredded cheddar cheese is a versatile and popular dairy product, it can quickly turn bad if not stored properly. Bacteria grow rapidly at temperatures between 40 °F and 140 °F, so it's important to keep shredded cheddar cheese refrigerated at all times. If left out at room temperature for more than two hours, it should be discarded.
When it comes to determining if your shredded cheddar cheese has gone bad, your sense of smell is one of your best tools. Give the cheese a sniff and trust your instincts. If it smells off, it's best to throw it away.
Taste is another important indicator of whether shredded cheddar cheese has spoiled. Take a small taste and pay attention to the flavour. If it tastes bad or unpleasant in any way, it's best to discard it. Even if you're planning to cook with the cheese, it's not worth the risk of potential foodborne illness.
In addition to smell and taste, there are other signs to look out for when determining if shredded cheddar cheese has gone bad. Discoloration, hardening, or drying out are all indications that the cheese has lost its freshness. The presence of mold is also a clear sign that the cheese should be thrown away, especially if it's a soft cheese.

Additives: Pre-shredded cheese contains additives to prevent clumping
Pre-shredded cheese is a convenient option for those who frequently use shredded cheese in their cooking. However, it's worth noting that this variety often contains additives to prevent the shreds from clumping together. These additives can include anti-caking agents such as cellulose, a powder derived from various sources, which gives the cheese an odd texture. Some manufacturers also use powdered potato starch or "plant fiber" derived from sawdust, which is labelled as "cellulose" or "plant fiber". These additives can affect the melting properties and overall taste of the cheese, so it's important to be aware of their presence when purchasing pre-shredded cheese.
The use of anti-caking agents is a common practice in the food industry, and they are generally considered safe for consumption. However, for those who prioritise taste and texture, shredding cheese from a block may be the preferred option. By shredding your own cheese, you can avoid the additives found in pre-shredded cheese and achieve a smoother, more natural melt. This is especially important if you plan to use the cheese for dishes like mac 'n' cheese or other recipes that require a creamy consistency.
The melting issues with pre-shredded cheese are often due to the high heat causing the cheese to separate into its components: casein (protein) and fat. To address this issue, it is recommended to use gentle heat when melting pre-shredded cheese. Additionally, it's important to store pre-shredded cheese properly to extend its shelf life. It should be kept in an airtight container or bag, with as much air squeezed out as possible, to prevent mould growth.
While pre-shredded cheese offers convenience, it's important to be aware of the additives it contains and their potential impact on taste and texture. For those who prioritise flavour and melting quality, shredding cheese from a block is the best option. However, for busy cooks who value time-saving options, pre-shredded cheese can still be a viable choice, especially if gentle heat is applied during melting. By understanding the characteristics of pre-shredded cheese and following proper storage practices, consumers can make informed decisions about their cheese preferences and ensure a pleasant culinary experience.
