What is the ideal refrigerator temperature to store food safely?

The ideal refrigerator temperature for safely storing food is at or below 40°F (4°C). This temperature range is essential because it slows down the growth of harmful bacteria that can cause foodborne illnesses. Keeping food at or below this temperature helps maintain its freshness and safety, as bacteria thrive in warmer conditions.

In practical terms, many refrigerators are set around 35°F to 38°F (1.6°C to 3.3°C), which is within the safe range. It is important for food handlers to monitor and maintain this temperature consistently, as fluctuations or higher temperatures could lead to spoilage and health risks.

While temperatures above 40°F (4°C) are unsafe because they permit bacteria to multiply more rapidly, temperatures below 30°F (-1°C) can cause food to freeze, which might impact texture and quality. Hence, maintaining the refrigerator at or below 40°F ensures that food remains safe while also preserving its quality.
