What is the ideal temperature for keeping cold foods?

The ideal temperature for keeping cold foods is at or below 41°F (5°C). This temperature is crucial for food safety because it helps prevent the growth of harmful bacteria that can cause foodborne illnesses. When foods are stored at this temperature or colder, the rate at which pathogenic bacteria multiply is significantly reduced.

Options that suggest higher temperatures, such as 50°F (10°C) or room temperature, do not adequately restrict the growth of bacteria, making them unsafe for storing perishable items. While 32°F (0°C) may be safe for freezing, it can lead to ice formation in some food items, which isn't ideal for maintaining quality in cold food storage.
