How long does it take for American cheese to go bad?

American cheese, being a processed cheese, generally has a longer shelf life than natural cheese.

Here's a breakdown:

* Unopened: American cheese can typically last up to 2-3 months in the refrigerator if stored properly.

* Opened: Once opened, it's best to use it within 1-2 weeks.

Here's how to know if American cheese has gone bad:

* Appearance: The cheese may develop mold, become slimy, or change color significantly.

* Smell: A sour or rancid odor is a sign of spoilage.

* Taste: If the cheese tastes sour, bitter, or off, it's likely bad.

Tips for storing American cheese:

* Refrigerate: Keep it in the refrigerator at 40°F (4°C) or below.

* Wrap tightly: Use plastic wrap or aluminum foil to prevent the cheese from drying out.

* Avoid cross-contamination: Wash your hands and any surfaces that come in contact with the cheese to prevent the spread of bacteria.

Remember, these are general guidelines, and the actual shelf life can vary depending on the specific brand and storage conditions.
