What temperature should a refrigerator be kept at to maintain safety and quality?

Explanation:
Keeping perishable foods cold to slow bacterial growth. When the fridge is at 40°F (4°C) or below, microbial activity slows a lot, which helps prevent foodborne illness and preserves texture, color, and moisture. The range between 40°F and 140°F is known as the danger zone because bacteria multiply quickly there; staying at or below 40°F keeps foods out of that zone for longer. Choosing a temperature around freezing (32°F/0°C) would freeze many items, which can change texture and quality for dairy, produce, and beverages, and isn’t necessary for safety in a standard refrigerator. Temperatures like 50°F or 60°F are well into the danger zone, allowing rapid spoilage and higher risk of illness. Therefore, the best practice is 40°F (4°C) or below.
