What temperature is typically used for a freezer?

Explanation:
Freezing foods to very cold temperatures slows or stops bacterial growth, helping preserve safety and quality during storage. A typical freezer is set to −18°C because this temperature keeps foods solid and extends shelf life reliably. Warmer temperatures, like 0°C, fall into the refrigerator range where microbes can still grow, while −12°C or −9°C aren’t cold enough to freeze effectively for long-term storage. Remember, freezing inhibits growth but doesn’t kill all microorganisms, so keeping foods consistently frozen is important.
