What temperature should my commercial upright freezer be set to for safe frozen storage in an Irish kitchen?

For commercial frozen storage in Ireland, a practical target is -18°C (or colder).

Setpoint vs product temperature: the number on the display is usually an air probe reading, not the core temperature of your food.

Best practice: aim for -18°C or lower at the warmest part of the cabinet during normal service, and verify with a calibrated probe between packs (or in a glycol test bottle) as part of your HACCP routine.

If you’re in a hot kitchen or high-access location: you may need a slightly colder setpoint to maintain compliant product temperatures during peak openings, but avoid pushing it colder than necessary because it can increase running hours and ice build-up.
