Mozzarella cheese is a popular variety of cheese that is used in a variety of dishes. However, it can be difficult to determine if it has gone bad due to its subtle aroma. While many cheeses have a strong odour, mozzarella has a light and mild scent. If the mozzarella smells like sour milk or has an off smell, it has likely gone bad and should be discarded. Other signs of spoilage include visible mould, a chemical smell, or a vinegar odour. It is important to note that while cutting off the mouldy parts of some hard cheeses may be safe, it is not recommended for soft cheeses like mozzarella.

What You'll Learn
Mozzarella should have a light, mild aroma
Mozzarella can go bad in several ways. Firstly, mould is the most obvious indication that mozzarella cheese has gone bad. If mould appears on the cheese, it is best to discard it entirely. However, if you are confident in your ability to remove the mould, you can cut away at least 1 inch (2.5 cm) around and below the mouldy spot. It is important to note that not all moulds pose a risk, and some cheeses are grown with specific moulds and are safe to eat, such as blue and soft-ripened cheeses.
Secondly, discolouration can be a sign that mozzarella has gone bad. In one instance, Italian authorities found that mozzarella imported from Germany developed a blue tint due to the bacteria Pseudomonas (P.) libanensis.
Thirdly, an off smell is a sign that mozzarella has gone bad. This could be a pungent vinegar odour, a sour or yeasty smell, or a musty, sour, or smelly-foot odour. If the mozzarella has been sitting in liquid, the liquid could be whey leaching out, which is normal, but if the smell and taste are very strong, it might be a sign that the cheese has gone off.
Lastly, the packaging can indicate that mozzarella has gone bad. If the mozzarella is vacuum-sealed, a wrinkly package indicates freshness, while an inflated package indicates that the cheese is aging.

A bad smell, like sour milk, means it's gone off
Mozzarella has a light and mild aroma, so a strong, bad smell is often the first sign that it has gone off. If your mozzarella smells like sour milk, it's definitely time to throw it out. Other signs that your mozzarella has gone bad include a wrinkly vacuum-sealed package, visible mould, or a chemical taste.
If you're unsure, it's always better to be safe than sorry—discard the cheese. While tasting a tiny amount of old mozzarella is unlikely to make you sick, it's not worth the risk. Moist cheeses like mozzarella can harbour dangerous bacteria such as Listeria, E. coli, brucella, and salmonella. Foodborne illnesses can cause unpleasant gastrointestinal symptoms and, in some cases, lead to more serious health issues.
To prevent your mozzarella from going bad, wrap it tightly when storing it in the refrigerator. Mozzarella can quickly absorb flavours and odours from other foods, so keep it away from meat to prevent possible contamination. Large chunks of mozzarella will also keep longer than small pieces or slices, which generally begin to lose quality after a month or less.
If you notice mould on your mozzarella, do not attempt to trim it off. While mouldy soft cheeses like mozzarella should be discarded immediately, you can cut away mould from hard, low-moisture cheeses such as Cheddar, Parmesan, and Swiss.

A strong vinegar odour could be a sign of bad cheese
Mozzarella is a soft cheese with a high moisture content, which makes it susceptible to bacterial growth and spoilage. While it's normal for many cheeses to have a strong odour, mozzarella typically has a light and mild aroma. If your mozzarella has developed a strong vinegar odour, it could be a sign that the cheese has gone bad.
The vinegar smell in mozzarella cheese is often associated with the presence of acetic acid bacteria, which can indicate spoilage. These bacteria can produce vinegar-like compounds, giving the cheese an unpleasant odour. In some cases, the vinegar odour may be accompanied by a sour or yeasty smell, indicating the presence of other spoilage microorganisms.
Another indication of spoilage in mozzarella cheese is the presence of mould. While it is safe to trim mould from hard, low-moisture cheeses like Cheddar or Parmesan, mouldy mozzarella should be discarded entirely. Cutting away the mouldy portions of soft cheeses like mozzarella may not remove all the spores, and consuming them could lead to foodborne illness.
To determine if your mozzarella cheese is safe to eat, it's important to inspect both its smell and appearance. Fresh mozzarella should have a mild and pleasant aroma. If it smells like sour milk or vinegar, it's likely gone bad. Additionally, look for signs of mould or discolouration, which can indicate the presence of harmful bacteria.
If you're unsure whether your mozzarella cheese is safe to consume, it's always best to err on the side of caution and discard it. While small amounts of spoiled cheese may not cause serious illness, they can still lead to unpleasant gastrointestinal symptoms. Proper storage, such as wrapping the cheese tightly and storing it away from meat, can help extend its shelf life and prevent premature spoilage.

Fresh mozzarella is vacuum-sealed; air in the package indicates aging
Fresh mozzarella is often vacuum-sealed, and the presence of air in the package can indicate that the cheese is aging. This is because as mozzarella ages, it releases gases that cause the package to puff up with air. While a small amount of air in the package is normal, a puffed-up package may indicate that the cheese is past its prime.
Mozzarella cheese is a delicate product with a relatively short shelf life compared to other cheeses. It is important to check if it has gone bad before consuming it, as eating spoiled mozzarella can lead to foodborne illnesses.
One of the key indicators of spoilage in mozzarella is its smell. Fresh mozzarella has a light and mild aroma, so if it starts to smell sour or like sour milk, it is likely a sign that the cheese has gone bad. Other indicators of spoilage include visible mold, a vinegar odor or taste, and a blue tint caused by bacterial growth.
It is worth noting that not all mold on mozzarella cheese is dangerous. In some cases, you can cut away the moldy part and consume the rest of the cheese. However, this only applies to hard, low-moisture cheeses like Cheddar, Parmesan, and Swiss. For soft, shredded, sliced, or crumbled mozzarella, it is important to discard the entire package if mold is present.
To prolong the shelf life of fresh mozzarella, it is recommended to store it properly by keeping it tightly wrapped in the refrigerator, away from other foods with strong odors or meat to prevent contamination and absorption of unwanted flavors.

For example, pre-grated mozzarella may have a sour or yeasty smell, while brined varieties may have a musty, sour, or smelly-foot odour. If you are ever in doubt about the quality of your mozzarella cheese, it is best to err on the side of caution and discard it to prevent any potential health risks.
