What temperature should my upright fridge or freezer be set to for safe food storage?

For Irish kitchens, a practical target is:

Upright fridge (chilled): keep food at 0–5 °C. A common controller setpoint is +2 to +4 °C to allow for normal door openings and temperature swing.

Upright freezer (frozen): keep food at about -18 °C. Many sites run a controller setpoint around -18 to -20 °C so product stays safely frozen during busy service.

If you are regularly recording close to the limits (near 5 °C chilled or warmer than -18 °C frozen), adjust your operating routine (loading, airflow, door time) before chasing the setpoint lower or higher.
