Watch Out! These 10 Foods Are Probably Expired In Your Fridge Right Now

Deli meat

While the plastic packaging might appear to keep your sandwich fixings fresh, as soon as the slices are separated at the deli counter, their freshness begins to wane. Most sliced meat producers, including Boar‘s Head Brand, recommend that their products be consumed within three to five days of purchase, though it should be safe to eat them within 7 to 10 days of the sell-by date. Signs it’s gone bad: If it feels extremely slimy, if it smells remotely of vinegar, ammonia, or yeast, or if there’s any mold or other growth on the meat or the package.
