Frequently Asked Questions

Q

How long does milk last after opening?

Opened milk lasts 5–7 days in the fridge at 34–38°F. Whole milk tends to last slightly longer than skim. Always smell before using — sour odor means it has turned. Freezing extends milk to about 3 months but may change texture.

  • Whole milk (opened): 7 days refrigerated at 34–38°F
  • Skim/2% milk (opened): 5–7 days refrigerated
  • UHT/shelf-stable milk (unopened): 6–12 months at room temperature
  • Frozen milk lasts 3 months but may separate — shake well after thawing
  • The sell-by date is for stores, not safety; milk is often good 5–7 days past it

Q

How long do leftovers last in the fridge?

Most cooked leftovers are safe for 3–4 days in the fridge at 40°F or below. This includes cooked meat, pizza, soup, casseroles, and pasta. Refrigerate within 2 hours of cooking. For longer storage, freeze within 4 days.

  • Cooked chicken, beef, pork: 3–4 days refrigerated, 2–4 months frozen
  • Pizza: 3–4 days refrigerated, 1–2 months frozen
  • Soups and stews: 3–4 days refrigerated, 2–3 months frozen
  • Cooked rice: 4 days refrigerated (Bacillus cereus risk if left out over 2 hours)
  • Use shallow airtight containers for faster cooling and better preservation
Q

Does the "sell by" date mean food is expired?

No. "Sell by" dates are for stores to manage inventory, not food safety. "Best by" indicates peak quality, not expiration. Only infant formula has a federally regulated expiration date. Most foods are safe well past these dates if stored properly.

  • "Sell By": store guidance for stock rotation — food is typically safe 3–5 days after
  • "Best By" / "Best Before": quality indicator — food may lose flavor or texture but is usually safe
  • "Use By": manufacturer's last recommended date for peak quality
  • Canned goods are often safe 1–2 years past the printed date if the can is intact
  • When in doubt, check for off smells, unusual color, slimy texture, or mold before discarding
Q

How long does raw chicken last in the fridge?

Raw chicken lasts only 1–2 days in the fridge, whether opened or unopened. Store at 32–34°F on the lowest shelf to prevent dripping. If you won't cook it within 2 days, freeze it immediately — frozen chicken lasts 9–12 months.

  • Whole chicken: 1–2 days refrigerated, up to 12 months frozen
  • Chicken pieces (thighs, breasts): 1–2 days refrigerated, 9 months frozen
  • Ground chicken: 1–2 days refrigerated, 3–4 months frozen
  • Cooked chicken: 3–4 days refrigerated, 2–4 months frozen
  • Place raw chicken in a leak-proof bag on the bottom shelf to prevent cross-contamination
Q

Can you freeze bread and how long does it last?

Yes, bread freezes well for 3–6 months. Slice before freezing so you can thaw individual pieces. White bread lasts about a week on the counter and 2 weeks refrigerated. Whole wheat spoils faster due to higher oil content in the bran.

  • White bread: 5–7 days pantry, 2 weeks fridge, 3–6 months freezer
  • Whole wheat: 4–5 days pantry, 10 days fridge, 3–6 months freezer
  • Freeze in original bag with excess air squeezed out, or use a freezer bag
  • Thaw at room temperature or toast directly from frozen — do not microwave (makes it tough)
  • Refrigerating bread actually makes it go stale faster due to starch retrogradation
