What is the best way to apply FIFO stock rotation in freezers?

Make FIFO a physical system, not just a policy.

Two-step loading rule: when deliveries arrive, pull the older stock forward first, then load new stock behind or below it.

Use a front-to-back or top-to-bottom direction: choose one direction per freezer type and stick to it (e.g. uprights: older at front, chests: older in top baskets).

Date codes must be visible at pick point: if the date is on the side you can’t see, relabel the front edge.

Quarantine “unknown date” items: have a small clearly marked crate for anything that arrives without a legible date. Either label it immediately or reject it for storage.

Set a quick audit cadence: a 5 minute daily glance (front row and top baskets) plus a weekly deep tidy catches expired or buried stock before it becomes waste.
