The shelf life of sliced cheese in a refrigerator can vary depending on the type of cheese and its packaging. In general, here are some guidelines for how long sliced cheese can last:
Unopened packaged sliced cheese: When kept in the original, unopened packaging, sliced cheese can last beyond its "best by" or "use by" date, which is typically printed on the package. It can remain safe to eat for about 1 to 2 weeks after the date indicated, but the quality may start to decline over time.
Opened packaged sliced cheese: Once you open the package, the shelf life of sliced cheese is shorter. It's best to consume the cheese within 3 to 7 days after opening to ensure its quality and safety. Properly resealing the packaging or transferring the slices to an airtight container can help extend its freshness.
Deli-sliced cheese: If you have cheese sliced at the deli counter, it's recommended to consume it within 3 to 5 days. Deli-sliced cheese is generally less processed and may have a shorter shelf life compared to pre-packaged sliced cheese.
Keep in mind that these are general guidelines, and the actual shelf life can vary depending on the specific type of cheese, storage conditions, and any preservatives used in the cheese. Always use your best judgment and perform a visual and smell check before consuming sliced cheese to ensure it hasn't spoiled.
If the cheese shows signs of mold growth, a slimy texture, or an off-putting odor, it's best to discard it, as these are indicators that the cheese has gone bad and may no longer be safe to eat.
