Parmesan cheese, a staple in many kitchens, is known for its distinct nutty flavor and versatility. However, concerns have arisen regarding its potential to turn blue, sparking questions about its safety and consumption. In this comprehensive guide, we will delve into the science behind this phenomenon, exploring the factors that contribute to blue mold growth on parmesan cheese and providing practical guidance on how to prevent and manage it.
Causes of Blue Mold Growth on Parmesan Cheese
Blue mold, a type of fungus, primarily occurs on parmesan cheese due to the presence of certain environmental conditions:
- Moisture: Blue mold thrives in moist environments. If parmesan cheese is not properly stored or exposed to excessive humidity, it can create an ideal breeding ground for the fungus.
- Oxygen: Blue mold requires oxygen to grow. When parmesan cheese is exposed to air, it allows the fungus to access the necessary oxygen for its proliferation.
- Temperature: Blue mold prefers temperatures between 40°F and 60°F (4°C and 16°C). Improper storage at these temperatures can promote mold growth.
Is Blue Mold on Parmesan Cheese Harmful?
Generally, blue mold on parmesan cheese is not considered harmful to consume. However, it can impart an undesirable taste and texture to the cheese. Moreover, individuals with mold allergies or weakened immune systems may experience adverse reactions.
How to Prevent Blue Mold Growth on Parmesan Cheese
To prevent blue mold growth on parmesan cheese, follow these best practices:
- Proper Storage: Store parmesan cheese in an airtight container in the refrigerator at temperatures below 40°F (4°C).
- Vacuum Sealing: Vacuum sealing parmesan cheese removes oxygen and creates an inhospitable environment for mold growth.
- Regular Inspection: Regularly inspect parmesan cheese for signs of mold. Discard any cheese with visible mold growth.
- Avoid Prolonged Exposure to Air: When using parmesan cheese, minimize its exposure to air to prevent contamination.
How to Remove Blue Mold from Parmesan Cheese
If you discover blue mold on a small portion of parmesan cheese, you can attempt to remove it following these steps:

When to Discard Parmesan Cheese with Blue Mold
If the blue mold has penetrated deeply into the parmesan cheese or covers a large surface area, it is best to discard the entire block. Consuming cheese with extensive mold growth can pose health risks.
Other Factors Affecting Parmesan Cheese Color
In addition to blue mold, other factors can affect the color of parmesan cheese:
- Age: As parmesan cheese ages, it naturally develops a darker color due to the breakdown of proteins and fats.
- Additives: Some parmesan cheese manufacturers may add coloring agents to enhance the appearance of the cheese.
- Mold Culture: Certain molds, such as Penicillium roqueforti, are used intentionally in the production of specific types of cheese, such as blue cheese.
