Past Food Expiration Date: 3-4 weeks
Eggs are a protein and protein takes a while to break down. In fact, fresh eggs with unbroken egg shells can last up to 3-4 weeks after the expiration date has passed. Eggs removed from shells will only last a few days.
Pre-Packaged Deli Meat
Past Food Expiration Date: 7-10 days in fridge, ~7 months in freezer
Sealed, pre-packaged deli meat lasts for at least a week in the fridge. Processed deli meats last much longer. Salami will keep for about a month, and bologna lasts 1-2 weeks. Bologna is trickier because the ingredients vary based on company and price point. When in doubt, follow your nose and check for these other signs of spoiled food.
