Mozzarella string cheese is a relatively soft, fresh cheese that is individually wrapped and can last for a while without refrigeration. However, the question of whether it will spoil depends on several factors, such as the cheese's moisture content, how it is packaged and stored, and the temperature of its surroundings. While some sources claim that mozzarella can be left unrefrigerated for a couple of days without spoiling, others suggest that it should not be left out for more than two hours at room temperature. To ensure food safety and maintain the best taste and quality, it is generally recommended to store mozzarella string cheese in an airtight container in the refrigerator.

- Refrigerators often operate above the optimal temperature for preserving cheese
- Hard cheeses can last longer at room temperature than soft cheeses
Mozzarella is a soft or semi-soft cheese
Mozzarella has a high moisture content, and soft cheeses with higher moisture content are more perishable and less likely to last unrefrigerated. The U.S. Department of Health recommends that perishable food should not be left out of the fridge for more than two hours, and this is especially the case for soft cheeses like mozzarella. If left out overnight, soft cheeses like mozzarella should be discarded.
Fresh mozzarella is sold in small plastic containers or bags filled with water or whey. It is best eaten within a few days of opening, and should be consumed within one week. It is typically stored in water and has a much shorter shelf life than low-moisture mozzarella. Fresh mozzarella can be recognised by the distinct squeaky sound it makes when chewed or rubbed.
Low-moisture mozzarella is drier, denser, and saltier than fresh mozzarella. It is not stored in water and has a longer shelf life. It can be kept refrigerated for up to a month, and some shredded low-moisture mozzarella has a shelf life of up to six months. This type of mozzarella is good for dishes that require reliable, even melting, such as lasagne or pizza.
Mozzarella is also available in a processed form, which is sold in a tight plastic wrapper without any liquid. This type of mozzarella has a firmer, more rubbery texture than fresh mozzarella.

Soft cheeses are more perishable and spoil faster without refrigeration
Soft cheeses, such as mozzarella, cream cheese, cottage cheese, and ricotta, are more delicate and perishable than hard cheeses. They have a higher moisture content, which creates more opportunities for bacteria to grow, making them spoil faster without refrigeration. The U.S. Department of Health recommends not leaving perishable food, including soft cheeses, unrefrigerated for more than two hours. After this time, soft cheeses should be discarded as they pose a higher risk of bacterial growth and spoilage.
Hard cheeses, such as Cheddar, Parmesan, and Gruyere, on the other hand, can last longer at room temperature. They have a lower moisture content, making them less susceptible to bacterial growth. While they can be left out for up to four hours without significant safety risks, it is still recommended to store them in the refrigerator for optimal freshness and taste.
The freshness and type of cheese also play a role in how long it can be left unrefrigerated. Fresh cheeses, such as mozzarella, are more perishable than aged cheeses. Additionally, softer cheeses with higher moisture content, like Brie or Camembert, are more prone to spoilage and should be consumed within one to three weeks of opening, even when stored properly in the refrigerator.
To extend the shelf life of cheese, proper storage is crucial. Soft cheeses should be stored in their natural liquid in a plastic container and kept in the refrigerator. Hard cheeses can be wrapped in wax paper, parchment paper, or cheese cloth, then placed in a plastic bag or airtight container to prevent drying out while allowing breathability.
In summary, soft cheeses are more perishable and spoil faster without refrigeration due to their higher moisture content. To ensure food safety and maintain the best taste and quality, soft cheeses should be stored in the refrigerator and consumed promptly after opening.

String cheese is individually wrapped and lasts well without refrigeration
String cheese is a relatively soft, fresh cheese. However, because it is individually wrapped, it lasts very well without refrigeration. In fact, some people have reported that they have left string cheese uneaten for a couple of weeks without refrigeration and it was still fine to eat. The individual wrapping prevents the cheese from spoiling, as long as the packaging remains intact. If the package is damaged and lets in air and mould spores, the cheese will spoil.
Mozzarella is considered a soft or semi-soft cheese, and it is generally recommended that soft cheeses be discarded if left unrefrigerated for more than two hours. This is because soft cheeses have a higher moisture content, which creates more opportunities for bacteria to grow. However, mozzarella is also considered a low-moisture cheese, which may slow down spoilage.
The length of time that mozzarella string cheese can be left unrefrigerated may also depend on the brand and the ingredients used. Some sources recommend freezing cheese sticks if you plan to keep them unrefrigerated for more than a couple of days.
It is important to use your judgement when consuming any food that has been left unrefrigerated. Check for any signs of spoilage, such as a slimy texture, discolouration, mould, or an unpleasant smell, and dispose of the cheese if you have any doubts about its safety.

Refrigerators often operate above the optimal temperature for preserving cheese
Fresh mozzarella is a soft cheese with a high moisture content. Soft cheeses are more perishable and less likely to last unrefrigerated. They are also more susceptible to bacterial growth, especially when left out at room temperature. The U.S. Department of Health recommends that perishable food, including soft cheeses, should not be left unrefrigerated for more than two hours.
Mozzarella should be consumed within one week of opening and stored in the refrigerator. The ideal temperature range for storing cheese is between 35°F to 45°F (1.7°C to 7.2°C). Refrigerators often operate above this temperature range, which is not optimal for preserving cheese.
At temperatures above 45°F (7.2°C), soft cheeses like mozzarella will spoil more quickly and are at a higher risk of bacterial growth. Higher temperatures can cause soft cheeses to ripen too fast and spoil before their intended shelf life.
To preserve cheese for longer periods, it is recommended to store it at cooler temperatures within the optimal range. Storing cheese at cooler temperatures slows down bacterial growth and prevents spoilage. Additionally, maintaining a consistent humidity level is crucial for preserving cheese. Fridges are moist spaces, and fluctuations in humidity can affect the quality of cheese. Therefore, it is recommended to store cheese in a sealed container, preferably made of glass, to protect it from humidity fluctuations and odour transfer.
By storing mozzarella at the optimal temperature range and following proper storage techniques, you can maximise its shelf life and preserve its flavour, texture, and freshness.

Hard cheeses can last longer at room temperature than soft cheeses
While cheese is a staple in many households, it is important to know how long it can be left out of the fridge before it goes bad. The answer depends on the type of cheese, with hard cheeses like Cheddar, Parmesan, and Gruyere lasting longer at room temperature than soft cheeses like mozzarella, cream cheese, and ricotta.
Hard cheeses, such as Cheddar and Parmesan, are aged for longer periods, giving them a distinct, crumbly texture. This aging process reduces their moisture content, making it harder for bacteria to grow and cause spoilage. As a result, hard cheeses can be left out at room temperature for a few months without refrigeration, although they will last much longer if refrigerated.
On the other hand, soft cheeses, also called fresh cheeses, are made from fresh curds that have not been pressed or aged. This lack of aging results in a higher moisture content, creating a softer texture and a more perishable product. Soft cheeses are more susceptible to bacterial growth and should be consumed within one to two weeks when stored in the fridge. At room temperature, soft cheeses should be discarded after two hours to prevent food safety issues.
It is important to note that the quality of cheese, whether hard or soft, will also determine how long it lasts. Additionally, factors such as the temperature of the fridge and the storage method can impact the shelf life of cheese. To maximize the shelf life of hard cheese, it is recommended to store it in its original packaging when refrigerating to delay exposure to air and potential bacterial contamination.
In summary, hard cheeses can indeed last longer at room temperature than soft cheeses due to their lower moisture content and reduced susceptibility to bacterial growth. However, all cheeses should be stored properly in the refrigerator to maintain optimal freshness and quality.
