What's probably happening
Dates like 'best by' and 'sell by' are mostly about peak quality, set by the manufacturer, not a federal safety cutoff. Food can be safe past that date, or unsafe before it, depending on how it was stored.
How urgent is it
This matters most for perishables: dairy, meat, eggs, and leftovers. Shelf-stable stuff like canned goods and dry pasta is far more forgiving.
What to do first
Use your senses first: smell, texture, and appearance catch most spoiled food before a date on a label does.
Can I handle this myself
Cooked leftovers are generally fine for 3 to 4 days in the fridge. Raw meat and poultry should be used or frozen within a couple of days of purchase. If something smells off, looks slimy, or has visible mold on a food that isn't supposed to have it, toss it, don't taste-test to find out.
When to call a professional
If you've eaten something questionable and start feeling sick, that's a call to a doctor or poison control, not a judgment call to make alone.
What it might cost
Free, this is about using your judgment, not buying anything.
What to gather first
None needed, just the item in front of you.
Mistakes to avoid
Treating 'best by' as a hard safety deadline, or ignoring obvious mold and smell because the date hasn't passed yet.
