What Is FIFO?

FIFO stands for "First In, First Out." It's a simple inventory principle used in professional kitchens and grocery stores: the oldest items get used first, and new items go to the back.

Why FIFO Works at Home

Most home kitchens work the opposite way — new groceries go to the front, old items get pushed to the back, and eventually they expire unnoticed. FIFO reverses this so nothing gets forgotten.

FIFO for Your Fridge

When you unpack groceries:

  1. Take older items out and move them to the front
  2. Place new items behind them
  3. Group similar items together (dairy with dairy, vegetables with vegetables)
  4. Check expiry dates as you go

FIFO for Your Freezer

Freezers are where food goes to die. Items get buried and forgotten for months. Use FIFO by:

  • Labeling everything with the date you froze it
  • Keeping a freezer inventory list
  • Rotating older items to the top or front
  • Planning meals around what needs to be used soonest

FIFO for Your Pantry

Canned goods, pasta, rice, and cereals all have dates too. Use clear containers so you can see what you have, and always put new purchases behind older ones.

Combine FIFO with FreshGuard

FreshGuard's location-based inventory makes FIFO effortless. See exactly what's in your fridge, freezer, and pantry at a glance. Get reminders when items are approaching their expiry date so you use them first.

The Bottom Line

FIFO is free, takes seconds to implement, and can meaningfully reduce food waste at home. Start today — your wallet will thank you.

FIFO only works if you can see what you own. Put older items at the front, newer ones behind, and avoid storing the same product in several places. A quick weekly sweep — five minutes before shopping — prevents duplicates and surfaces items that need to be used first. Labels with the date you opened or cooked something make rotation much easier.

Practical checklist

  • Check the fridge and pantry before you shop.
  • Keep older items at the front and newer ones behind.
  • Label leftovers with the date they were cooked.
  • Plan two "use it up" meals each week.
  • Track what you throw away for one week to spot patterns.
