What is regarded as the ideal temperature range for refrigerator storage?

1. -4°C to 0°C

2. 0°C to 4°C

3. 5°C to 8°C

4. 10°C to 12°C

The correct answer is: 0°C to 4°C

The ideal temperature range for refrigerator storage is crucial for ensuring food safety and preventing the growth of harmful bacteria. This specified range, which is between 0°C and 4°C, effectively slows down the growth of microorganisms that can lead to foodborne illnesses while maintaining food quality and freshness. When food is stored within this range, it remains adequately chilled without freezing, which can compromise the texture and taste of certain items. This temperature zone is universally recognized in food safety guidelines, making it a standard recommendation for effective food preservation in residential and commercial refrigeration settings. In comparison, the other temperature ranges listed do not provide optimal conditions. The first range, for instance, risks freezing items and can lead to cellular damage in certain foods. The ranges of 5°C to 8°C and 10°C to 12°C are above the recommended threshold, allowing for the rapid growth of bacteria and increasing the risk of food spoilage and foodborne illnesses. Thus, the temperature range of 0°C to 4°C is essential for food safety and quality.
