What temperature is typically used by freezers to slow bacterial growth and preserve food?

Explanation:
Freezing at around -18°C slows bacterial growth and preserves food because it drops water activity and drastically slows or virtually stops microbial metabolism and enzymatic reactions. This keeps the food safer for longer by preventing spoilage and pathogen multiplication during storage. Fridge temperatures (0°C or 4°C) are too warm for freezing and allow microbes to continue growing slowly, while -80°C is used in labs for long-term storage of samples, not typical food storage. So, -18°C is the standard setting for freezing foods.
