Can one week old cheese make you sick?

Here's why:

* Cheese is a fermented food: The process of making cheese involves bacteria, which helps to break down the milk and create the distinct flavor and texture. These bacteria are generally considered beneficial and are unlikely to cause illness.

* One week is not very long: Most cheeses are safe to eat for several weeks, even months, after their "best by" date.

* Signs of spoilage: You would likely notice signs of spoilage before the cheese became unsafe, like a strong, unpleasant odor, mold, or a slimy texture.

However, there are some exceptions:

* Soft cheeses: Some soft cheeses, like brie and camembert, are more susceptible to spoilage because they have a higher moisture content. They may not be safe to eat for as long as harder cheeses.

* Unpasteurized cheeses: Unpasteurized cheeses are made with milk that has not been heated to kill harmful bacteria. These cheeses carry a higher risk of foodborne illness, especially for people with weakened immune systems.

To be safe:

* Check the label: Look for the "best by" date and try to consume the cheese before then.

* Smell and inspect: Before eating, smell the cheese and check for any signs of spoilage. If it smells bad, looks moldy, or has a slimy texture, discard it.

* Refrigerate properly: Store cheese in the refrigerator at 40°F (4°C) or lower.

If you are concerned about the safety of your cheese, it's always best to err on the side of caution and throw it away.
