What is the ideal temperature for refrigerator storage to prevent bacterial growth?

The ideal temperature range for refrigerator storage is between 32°F to 40°F (0°C to 4°C) because this range effectively slows down bacterial growth, ensuring the safety and longevity of perishable food items. Within this temperature range, the cold environment helps to inhibit the proliferation of harmful bacteria that can thrive at warmer temperatures.

At temperatures below freezing (0°F to 20°F), food can become frozen, which may alter texture and quality when defrosted, making this option inappropriate for refrigerator storage. Conversely, when temperatures rise above 40°F, particularly in the upper ranges of 41°F to 50°F or 45°F to 60°F, the risk for bacterial growth significantly increases, as these conditions create a more favorable environment for pathogens. Therefore, the specified range of 32°F to 40°F serves as the optimal zone for maintaining food safety in refrigeration.
