The Risk Of Consuming An Expired Parmesan Cheese
Parmesan is a sort of hard cheese that is pretty long-lasting, and if properly stored, it can remain edible for quite a long period of time.
An unopened package of this cheese can last for as long as seven months and up to nine months.
As for the opened packet, its lifespan is, of course, shorter and consists of one or two months at most.
However, such durability does not mean parmesan can't spoil. If we store the cheese improperly, it can develop various signs of spoilage:
- mold
- rind color change
- off smell
- texture
- rancid or sour taste
- clumping
Mold is especially dangerous since quite many kinds of it are rather harmful and can cause serious diseases. And even if in most cases we can cut the moldy parts of the parmesan block and safely eat the rest of the cheese, there is always a chance that the spores of harmful mold can also spread over the surface of the cheese.
If you eat spoiled parmesan that has mold on it, you take a huge risk since harmful bacteria can get into your stomach, such as:
- Salmonella
- coli
- Listeria
- Brucella
- Penicillia
- P. Roqueforti
This is why, in order to avoid severe food poisoning, always check your cheese carefully for any signs of quality decay before tasting it

How to Store Parmesan Cheese
Storing cheese is a bit tricky. We guess quite many of us had to discard the leftover cheese because it became slimy earlier than we expected. That's because the proper conditions were not provided for the product.
Parmesan cheese expiration strongly hangs upon where and how we keep it.
The cheese will stay fresh if we wrap it tightly into a plastic cover and refrigerate.
