What temperature should perishable foods be kept at to ensure safety?

Perishable foods should be stored at temperatures below 40°F (4°C) or above 140°F (60°C) to ensure safety. This temperature range is crucial because it inhibits the growth of harmful bacteria that can cause foodborne illnesses. Foods kept below 40°F are in the 'safe zone' for refrigeration, slowing down bacterial activity significantly. Conversely, maintaining temperatures above 140°F ensures that food is kept hot enough to prevent bacteria from thriving.

In contrast, storing perishable items at room temperature does not prevent bacterial growth and can lead to rapid spoilage. Maintaining temperatures between 60°F and 75°F creates a favorable environment for bacteria to multiply. Additionally, relying solely on cooking to make food safe is not sufficient, as some foodborne pathogens can produce toxins that are not destroyed by cooking. Thus, proper temperature control is essential for food safety.
